Why didn't Izuku's mom ask about his quirk?
Izuku was quirkless before, but then he got One For All. His mom saw him use his quirk in the Sports Festival, but she never asked him how he got his quirk. And Izuku told All Might that he hadn't told anyone about One For All, not even his mom. Yet, his mom never asked him about his quirk. Why didn't she say anything?

May be she thought he developed his quirk late in life?

@Pablo that is possible but she never asked about when he got his quirk and what his quirk was or anything else.

I can think of a few possible reasons why this would have happened.

Izuku's mother assumed that he developed his ability at some point, but chose not to use it often due to its side effects. In this case, she may not have mentioned it, realizing it may be a sensitive subject.
Izuku has a very close relationship with his mother, and people with these types of relationships can often tell a lot more about each other than most. His mother likely sense that, for whatever reason, he didn't want to talk about his quirk, and decided not to press the issue.
She asked Izuku offscreen, and he deflected her question somehow; which would end up resulting in the same effect as 1. or 2.

This is about Dekus mom knowing about the quirk   I just watched season 3 episode "From Iida to Midoriya"  and whilst on the train Deku has a flashback.  Earlier at the hospital he was on the phone with his mom and she asked him do you have to go back to UA. We don't hear what he says until this flashback.  He says mom All Might gave me everything, he trusted that I'd make the most of his quirk. This happens at just over 15 mins into the episode.  I've watched this series many times and it's the first time I caught that confession.  If you go back to the part where he's on the phone with his mom then fast forward to the confession he's still got the cellphone to his left ear and wearing the same clothes. The part that is confusing is a later episode when they talk to his mom , all might does say he's his chosen successor to be the next symbol of peace but she seems clueless to how he got his quirk. So I'm confused,  The only other possibility is it's just his thoughts and it wasn't a real conversation, what do you think?

I don't remember Deku confessing but anyway it's in season 3. Deku got his quirk in season 1 so I was asking why his mom didn't ask about it back then. I got the answer though. She just thought he developed his quirk late.

Sorry I didn't even realize this was just to answer a question,  I was writing what I had just watched and was curious if others had seen that flashback and whether they thought Midoriya said it out loud to his mom or did he just think the statements we heard, whilest talking to his mom. I have no idea how to use forums properly this was only way I saw to talk about this general topic. Sorry I wasn't more clear when I posted.

There are some scenes after the ending in season 2 episode 12 where izuku and his mom talk about him having a quirk.

How are Clow Reed and Fei Wong Reed related in Tsubasa Reservoir Chronicle?
Considering that Clow Reed and Fei Wong Reed have the same surnames and that they both have magical powers, how are they related? It was not clearly stated on the anime series or manga how they are related (unless I overlooked it). Are they brothers or relatives? Or do they just coincidentally have the same surnames? (Though Yuko said there is no such thing as coincidence, there is only inevitability.)
I'll appreciate any details. Thanks a lot.

According to the Tsubasa Wikia:

Fei Wong Reed also mentions Clow quite frequently, and he's also a descendant of Clow.

This is shown in chapter 64, which appears in Volume 9 of the manga. He is described as somewhat of a distant relative of Clow Reed.
Information for this can be found on: Fei Wang Reed's Wikia page and Fei Wang Reed's section on Wikipedia. The citing is provided on the Wikipedia page.

So they are just relatives. I see. Thanks for the info.

In Chapter 233, page 20, of the Tsubasa Chronicles manga, Kurogane has a conversation with Fai and Fai mentions that Fei Wang could have been the afterimage of a wish made by someone with a great magical power. So instead of a relative, this might mean that it might be an unintentional (side) effect of a wish made by Clow.

Fei-Wang Reed was born from the wish Clow Reed made to revive Yuko. I think this goes far beyond being heavily implied, as it is pretty much confirmed by his actions, his motivations, and his dialogue. For instance, when he dies in chapter 231, he says,

The witch must be revived... That's the whole reason for my existence... And the message I must deliver to her... That is my reason... I am to...

Additionally, he shatters to pieces, his body falling apart after death as with all the clones in the series who died. I believe he is a clone of Clow Reed, in the same way Watanuki is a clone of Syaoran. Since Clow Reed was unable to revive Yuko, part of Fei-Wang Reed's motivations is to prove he is superior to Clow, by accomplishing what Clow could not do. It's possible that Fei-Wang was born from Clow Reed's regrets at having had to give up, and thus why he is so determined to carry out the wish.
But regardless of my little speculation spree, considering Watanuki was born from stopping Sakura's time, it isn't so far-fetched to think Fei-Wang was born from stopping Yuko's.
Here's what Fai has to say when Kurogane asks why Fei-Wang broke into pieces:

I don't know. But it may be that Fei-Wang... he himself was an image of somebody else. Or perhaps less a person... and more a very strong will. It could be the personification of a wish left behind by someone with enormous magical power.

As far as the story goes, the only known characters who fit the bill of having such powerful magical power are Clow Reed and Sakura. We also happen to know Clow Reed made a wish to save Yuko, so it seems like it's a mystery solved.
We could get into speculation and say there's simply some unknown character. There is simply no information to support such a theory, however, and I believe if that was the conclusion the authors wanted us to reach, they would have laid the groundwork.

Why did Hisoka want to kill Phantom Troupe's members?
I am not quite understanding why Hisoka tried to kill all Phantom Troupe member after he lost to its leader, Chrollo Lucifer. That fight, Chrollo vs Hisoka, I think is reasonable because Hisoka always intended to beat a person that more powerful than himself,

 but in the end he lost and was also confirmed dead by Shalnark.

From the very first Phantom Troupe's Arc, Hisoka doesn't seem to have that kind of urge to kill all Phantom troupe's member. After his rebirth from that battle between Chrollo Lucifer, he suddenly does have the urge to kill all of Phantom Troupes' member, this just escalated quickly mood from Hisoka. His first Victim from the group were

 Shalnark and Kortopi, in chapter 357

What's his motive to kill all Phantom Troupe's member?

The thing is, it's quite hard to interpret or understand Hisoka's motives. So, as to the reason behind Hisoka's seemingly abrupt decision to kill or hunt down all Phantom Troupe members, we don't know yet as of now unless it will be revealed in upcoming chapters. Chapter 357 also surprised me as his decision was so sudden.
What we do know, either from reading the manga or watching the anime, is that Hisoka is someone who gets off or is 'turned on' when fighting someone who is strong, either stronger than him like Chrollo or someone with potential like Gon. This could probably mean that he either has Agonophilia or he's an adrenaline junkie. He probably wants to fight all of the Troupe members, believing it would give him great arousal or excitement since he probably realized they could be worthy opponents after his fight with Chrollo. But again, this is just a possibility based on his actions. We can't be sure unless Togashi explicitly shows this in the future.
It would be, however, hasty to immediately conclude that he did it 'just because' with no reason or plan. He's not like that and he plans all his moves, as can be seen, for example, in his fights during the Heavens Arena arc. As to his exact plans for antagonizing all of the members of the Troupe, it also has yet to be revealed.

but, in chapter 357, he defeated some of phantom troupe member easily because their ability were "stolen" by chrollo. It's contradicted, since what i know Hisoka only want to fight person when they are in good condition to fight against him.

@Gagantous 'Hisoka only want to fight person when they are in good condition to fight against him' During the Hunter Exam, this was not the case, though. Remember how he killed those group of people in that misty area? Or when he killed someone just out of pure bloodlust when Gon was tailing him? The Troupe has no quarrel with him but by killing 2 of their members, he's made enemies with all of them. This was probably in the hopes of fighting all or some of them at the same time. But again, this is just speculation based on how much he craves excitement from fighting.

From the first instance where we learned that Hisoka was trying to fight the leader of the Phantom Troupe Chrollo Lucifer, one of the major obstacles in his path were the other members of the Phantom troupe, several of whom were formidable nen users, and some are at least comparable to Hisoka's combat abilities. If Hisoka turned against the leader the other members would not allow him the fight, and would run interference.
Most of Hisoka's actions during the Phantom Troupe vs Kurapika arc is motivated by him wanting to physically separate Chrollo Lucifer from the rest of the members, and have a 1 v 1 matchup. Which didn't come to pass, seeing as how

 Kurapika sealed Chrollo's nen abilities.

When he did finally manage to weasel out a neutral match out of him, Chrollo insisted that it take place in Heaven's arena, after he had enough prep time. During their match, Chrollo used several of his new abilities, stored in the dictionary. Furthermore, he borrowed abilities of fellow troupe members Machi, Shalnark and Kortopi, and involved the crowd gathered in the arena as disposable pawns, to essentially kill Hisoka. It is implied that these three had further involvement in his loss, seeing how the exact three members were present after the match, to confirm Hisoka's death.
But, after

resurrecting himself using his post mortem nen

Hisoka restrains Machi and declares that he is going to hunt every Troupe member that he will come across.
Shortly after he

 confronts Shalnark and Kortopi and kills them with ease; decapitating Kortopi, and leaving Shalnark's corpse as a macarbe display for Chrollo.

While it is not stated outright, it is implied that Hisoka came to the conclusion, that as long as the limbs of the spider are present, he would never get to have a true 1 v 1 with chrollo.

It is also possible that Hisoka saw Chrollo borrowing the troupes abilities during their match, as them 'intruding' on their duel. Despite being a murderous psychopath with a fetish for fighting strong opponents, Hisoka has his own set of (twisted) code of conduct. Somewhat similar to a perverted version of the 'warrior's way'. Which is part of the reason why he admires fighters like Gon, who value the agreement between fighters and comes at him with no underhanded tactics, and nothing held back.
As soon as he was revived, his mind was already planning their next duel. Realizing that the other Phantom members are always going to be an obstacle, he decides to eliminate them all, before going after the head of the spider. Plus, by going after and killing the exact 2 out of 3 members from whom Chrollo borrowed abilities, and thus 'intruded' on their duel, he is sending a message to Chrollo. That being, 'you had them interfere in their match, and now your actions have led to their deaths'. This will work, as we have already seen how, despite being sociopathic mass murderers with no morals, the Troupe members care for their own, and would go ballistic when a member is harmed.
Happened when

 Uvogin was killed, and same thing happened now. Seeing as how now, the entire troupe is abroad the Kakin expedition ship to the Dark continent. I would go as far as to say that, Hisoka's managed to confine the notoriously slippery phantoms in one location, with little chance of wiggling their way out, or escape.

Much like Rorsharch says in Watchmen, "I'm not locked in here with you, you're locked in here with me"
Personal Note: I would be ecstatic if the successor arc concluded with Hisoka having curb stomped, most if not all spiders, especially Chrollo. Go for team Hisoka. (I know that rooting for a psychopath killer over some sociopath career criminals might not seem that good of a position to take, but what can I say.)

It's because hisoka fought chrollo and chrollo used the phantom troupes powers to aid him in the fight, so he's going to kill them all in order to have a fair fight with chrollo.
because killing the user removes the ability from chrollo's book.

So why he didnt kill mari ? She is phantom troupe member after all

Please include relevant sources/references. Because stealing abilities also results to the original user unable to use that ability anymore.

@Gagantous Because she healed him after getting defeated from chrollo.

@W.Are Chrollo took Shalnark and Korotopi's Hatsu to defeat Hisoka, Hunter × Hunter - Volume 34, Chapter 351
Chrollo asks if they wants their abilites back, Hunter × Hunter - Volume 34, Chapter 357
They allow Chrollo to keep them and die to hisoka defenseless.

@W.Are Killing the owner of an ability Erases the ability from Chrollos book  Hunter × Hunter - Volume 34, Chapter 352

@Nick I don't think that's enough reason for Hisoka to spare Machi. Also, while killing the owner erases the ability, that does not really explain why Hisoka wanted to kill them all. Chrollo didn't steal all their abilities and even with them dead, Chrollo can still acquire more. I doubt the Spiders' abilities are only the abilities he stole or is keeping in his book. So I don't think that because he wanted to have a fair fight is a reason.

@Nick Also, Machi sees him as enemy now. I doubt that he can still force her to heal him. He might as well have killed her there as she's also a formidable enemy. But he didn't, and the reason is not clear yet...

@W.Are It's very troublesome for chrollo to steal an ability, His phantom Troupe are 100% willing to allow him to take their abilities (especially because he can return them). The Phantom troupe members have good abilities and they make it easier for chrollo to steal. Hisoka wanted to see Chrollo's Strength not a combined effort from the other Phantom troupe. That's not what makes Hisoka erect.

@W.Are Also, Hisoka wanted to take Machi on a date during Heavens arena after she healed him from the battle with kastro. He just likes her, Thats the only reasoning the fans can go off of from reading where I left off. All the info I have is before the Kakin Boat Arc. Either Togashi hasn't wrote another reasoning for Machi to stay alive, Hisoka liking her is enough or I just need to keep reading.

@Nick 'Also, Hisoka wanted to take Machi on a date during Heavens arena after she healed him from the battle with kastro.' If that's how you interpret it, okay. But Hisoka was just flirting. Can we really truly say he wanted to take Machi on a date because he was serious about her?

@Nick Chrollo seems formidable enough even without the Phantom Troupe's abilities (IIIRC, he did not have any of the abilities from the Phantom Troupe when he fought the Zoldycks). So I don't think he relies that much on the Spiders' abilities. He's strong, even without the troupe's help.

@W.Are I have no idea man, but i answered the question. The literal reason for her being alive is because he likes her. Whether he's just flirting or not is subjective and irrelevant to the original question.

@W.Are More reasoning that hisoka just likes her.
https://i.imgur.com/alYNF10.jpg

@W.Are also its not about chrollo being strong, its chrollo denying hisoka from seeing what he actually fights like.

probably hisoka realized that lying in wait made him become rusty. Evidence is that when he fought chrollo, the latter showed off his offensive strategies, while the former observed in amazement. After his rebirth, hisoka considers he might have caused his own loss and swears to become a new person entirely.

In my opinion its because, whenever Hisoka was fighting with Chrollo, he was actually 1(Hisoka) vs 4(Chrollo, Machi, Shalnark, Kortopi). And it is obviously unfair matchup. I found this video very helpful explaining hisoka reason to kill every troupe.
Part1: https://www.youtube.com/watch?v=-Km6l5gRXuY
Part2: https://www.youtube.com/watch?v=E2vsYFYMD1g

this doesn't answer the question to Hisoka's motives. if the answer is in any of the youtube link you have linked to it's best that you summarize the relevant information from then in the event the videos were to be removed

why did machi involved on that match ? chrollo didnt steal machi's ability

@Gagantous this pictures might help explain your question.
http://i.imgur.com/dhu7ZZ6.png
Right picture source: Chapter 355

i think that's shalnark ability, not machi

shalnark have two anthena

@Gagantous, yup perhaps he have 2 antenna, but Hisoka is holding a different kind of antenna. And most likely like Machi antenna. https://vignette.wikia.nocookie.net/hunterxhunter/images/3/33/Machi_2011.png/revision/latest?cb=20150614135352

Why did Father create his "children" as the 7 deadly sins?
In both the manga and the 2nd anime (FMA Brotherhood) homunculi are willingly created. As far as I understand it, Father was created (or rather summoned from the other side of the door?) back at Xerxis before using the entire city to create a powerful philosopher's stone for himself and van Hohenheim.
Some time passed by and father started creating other homunculi, each named after and behaving according to a deadly sin. They are fueled by parts of Father's stone and are powerful subordinates, but neither Greed nor Sloth nor Gluttony use their power to any mentionable extent for Father's benefit.
It is commented by van Hohenheim (and apparently the commonly excepted "truth" as seen in this post) that Father wanted to get rid of these "human" weaknesses. But that obviously didn't work: He still is immensely proud, so he sits alone in the center of the state, never standing up, making subordinates and machines do everything for him, thinking of himself as the best and most powerful being on earth and working towards becoming a "perfect being"; He is greedy, so even though he has a powerful philosopher's stone and can create others from criminals and war casualties, he creates a stone way stronger than his old one has ever been and uses its power to enslave god and steal his/her/their/its power.
And he would have been successful if his underlings had used their powers to their whole extent instead of being too lazy, dumb, or greedy to do so. Van Hohenheim barely completed the inversion circle in time, and with faster digging at Sloth's end and Greed/ Gluttony going on a rampage to enforce the needed bloodshed, Father would have won. (Sure he still needed the sacrifices but as we see in the show, he can somehow make someone a sacrifice by force or he could have just ordered state alchemists to do things that made them become sacrifices. And that's not even the point.)
Is there another reason that I overlooked in the anime or that has been given in the manga why he created his "children" the way he did? Or a reference on why the plan of getting rid of these character flaws did actually work but just not entirely?

Whether or not it actually worked does not necessarily affect whether Father believes it worked, which I believe he did (probably up to the very end, based on his conversation with the Truth). Also consider this: is it really being greedy if you deserve what you're taking? Is it being proud if you really are as great as you believe? I can't really answer the question, but I think these are points and perspectives to consider.

I do agree that homunculus might think that it worked. On the other hand that would prove that it didn't work. According to this theory video (granted it is one of the weakest ones fact-wise compared to The Film Theorists' other videos), if the plan did work, Father should be tempered and humble. At least humble enough to realize that he is in fact still greedy, proud ...

How does Tomura Shigaraki's power not disintegrate his shoes?
In one chapter of the manga it's shown Tomura Shigaraki can disintegrate things with his feet. The disintegration activates apparently in the same way as the hands, when the 5 toes are in contact with the object. How does Tomura Shigaraki's power not disintegrate his shoes then?

This is purely speculation, but socks with holes in them.
Shigaraki's power only triggers if he touches the target with all five fingers/toes on one hand/foot.
So he could have special socks with holes for one or more toes.  Some toes touch the shoe, the others the sock, so neither decays.

The best guess would be socks with one hole for a toe. I am currently on that chapter so idk. I thought up until now that Tenko Shimura's (Tomura Shigaraki but we already knew this if we were this far) quirk could only be used through his hands. So this is a new development to me and pretty much all of us. Maybe the socks got damaged (If he wears special socks) during the whole fighting stuff or maybe when he disintegrated the building.

Welcome to Anime.SE! I'm not sure what this adds that isn't already in Xavon's answer from last year.

Tomura's power only triggers if he touches the target with all fingers on one hand. So there is no case in which he have holes in his socks or his shoes. His quirk only flows thru his hands.

The question clearly states that his Quirk also flows through his feet.

Yeah my bad. I didn't saw he said in manga. So to trigger his power all fingers/toes of one hand/ toe should be in contact only then his quirk works. So it is a possibility that all the fingers of his toe are not touching the same object or might be put his fingers up -down way

Why isn't Raku Ichijou's mother's face ever revealed in the manga?
Why isn't Raku Ichijou's mother's face ever revealed in the manga?
I mean, the manga ended, and she was the last character introduced in the series. What was the need to hide her face then?

I can think of three reasons to obscure or hide a character's face in a story.

Hazy memory. Another character's memory of this person is unclear, so their face is not shown. This has actually been done in Nisekoi and is actually a major driving point of the plot, since Raku Ichijo can't remember the face of the girl he made the promise to. In flashbacks, the girl is depicted without showing her face.
Focus. This character is not the current focus of the story, so their face is not shown. I saw a good example of this in the Watamote anime, at the end of episode 8. When Kii-Chan is going home, she is in the car with her mother, but her mother's face is not shown. The focus is on Kii-Chan sharing her experiences for the day, and her mother is just there so she has someone to talk to. Her mother is not the focus of the story.
Veneration. The character is too important to show, or showing them might somehow reduce their mystique. For historical or religious figures, one might not want to show their face in order to glorify them. For instance, figures like Saint Anselm, Oda Nobunaga, and the Buddha might have their faces obscured to show that they are too great to be depicted.

I suspect the case of Ichijo's mother is a combination of all three.

As previously mentioned, Nisekoi made extensive use of hazy memory in it's story. It's unclear what exactly Ichijo's relationship with his mother is like, but given she doesn't appear in most of the story, it's possible Ichijo hasn't seen her in a long time, and thus his memory of her is hazy. Likewise, the other characters haven't seen her in a long time, if at all, and thus her face is not depicted in flashbacks.
The focus on the scene where she returns may be more on the information Chitoge is getting from Raku's mother rather than his mother herself. The character is less important than the revelations she's sharing and Chitoge's reactions to these revelations.
The veneration point, I think, is the most important one here. Ichijo's mother is the author of the Zawze in Love children's novel, which is so important throughout the series. This book has almost mythic importance to the children, and they act out the events in the book through the keys and locket they have. As the author of this book, Raku's mother is a highly important person. Depicting her may lead to disappointment, as she would lose some of her mystique, and that in turn could make the children's book lose mystique. In order to maintain the mystique around her, and thus preserve the mystique of the Zawze in Love story, the author decided not to depict her appearance.

As mentioned in the other answer, a character's face might also not be shown due to constraints. Designing a character takes some time and effort. Shortcuts might be made for less important characters and background characters to get the manga out on time. I personally don't think this is the case for Ichijo's mother, but it is a point worth considering.
Though not related to Nisekoi, here's a quotation from the author of A Silent Voice, Yoshitoki Oima, on choosing not to draw the face of a different character, which will give a little insight on why sometimes characters' faces aren't drawn in.

Her face doesn't appear in the manga because I thought that would make her character stand out more. Once you draw a character's face and expressions, that takes on a certain meaning and it affects the story.

Is Holo different from other nonhumans?
It seems to me that the introduction of nonhumans who aren't wolves introduced a break from the initial premise, and additionally it seems that all other nonhumans don't clearly have all of the attributes Holo and Myuri have, so I'd like some clarification.
From the initial story, Holo claimed to be a wolf, and she seemed to indicate kinship with other wolves. To be clear, she identifies mainly as a wolf, not a human, and her human form is treated as a guise. My understanding of this initially was that it indicated all wolves in this world were at human level intelligence, or at least smarter than normal animals, and might have the potential to take human forms. However, this assumption was probably wrong since there are shown to be avatars of birds, sheep, etc.
With regard to these other nonhumans, there seem to be differences to Holo. Firstly, Holo has the attribute of living in and having power over wheat (also, she is required to eat it to transform back into a wolf). I don't recall other nonhumans having any similar trait disclosed. Secondly, I haven't seen in the others the aforementioned kinship that Holo has for wolves. Our two sheep, for instance, are quite disrespectful to regular sheep. In volume 10 of Spice and Wolf,

 we learn that the golden sheep has been eating sheep in order to fit
 in to human society.

Then in volume 3 of Wolf and Parchment, after offering to buy mutton for Myuri and Col, on page 188 Ilenia goes on to explain, "They look like kin, but in the end we're very different." These two, and Ilenia definitively, don't seem to view the regular sheep as their kin. In contrast to Holo, they don't seem to identify themselves as sheep (though they also don't identify as human).
Holo's attitude couldn't be any more different from these two sheep. In fact, on page 168 of volume 10 of Spice and Wolf, she throws up after learning that the golden sheep has been eating sheep.
Another point of note, the new Spice and Wolf: Spring Log books have introduced two new wolves: Selim and her brother Aram. What is the significance of these two being able to hide their ears and tails in their human transformations when Holo cannot? Is there a difference between these two and Holo or are they all the same kind of "wolf"?
So, for clarification, is Holo the same kind of entity as the rest of these nonhumans? Do these other nonhumans have powers over things like wheat but they keep their affinity secret, or do they lack these traits? Is the kinship Holo feels for the wolves merely a difference in attitude or does it indicate that she is a different kind of being?

Is this in relation to season 2?  If so, can you mark the spoilers? I'm finishing up season 1 and about to watch season 2.

@YetAnotherRandomUser All specific references are to light novels that take place beyond what was covered by the anime. My question is basically about the author being inconsistent (or so it seems to me). To answer this question, I expect one would need to have read all the books. It could possibly be addressed in an author interview, or new information may come with new releases.

@YetAnotherRandomUser In response to your request to mark spoilers, I have marked the one from volume 10. The other references, I believe, do not comprise secret information, and are only minor spoilers.

Probably, how old is it have a point here. For example, Myuri doesn't have the same powers as Holo, and she can hide their ears or tail. Also, if you think on power, you have the story about Moon-Hunting Bear (It's unknown if they have an human avatar or not)

Obito's Clothes Affected by Kamui?
Obito's MS allows him to be intangible. But when it attacks, his clothes don't get damaged at all (or fall off of him).
If we take the assumption that things really close to him or in contact with him are also affected by Kamui, does that mean that a person holding him or a backpack he's wearing is also intangible?
Clothes has always been a plot hole in Naruto. Like how Madara magically gets new clothes when he becomes SSOP. Or when the head Pain gets wrecked so hard by Naruto, but his clothes only get somewhat torn.

Does that mean that a person holdings with him or a backpack he's wearing is also intangible? Yes, anything touching the individual who uses the Kamui is also affected by the justu
Kamui

Right Eye
Obito's right eye uses a short-range version of Kamui, which can only transport targets in close proximity to the user; physical contact with the target is seemingly required
...
This intangibility can be extended to anything the user is touching at the moment of activation

Anything that is touching the caster becomes intangible, including clothes.
In Naruto Manga Chapter 684, we see Obito instructing Naruto and Sakura to keep their hands on his person so they may teleport alongside Obito

What was the relation of Urahara's Bankai's name with its ability?
Urahara Kisuke's Bankai is "Kannonbiraki Benihime Aratame", which means Modification of The Crimson Princess' Dissection at the Doors of Avalokiteśvara.
Does the name have any meaning/significance to its ability to dissect and restructure virtually anything (either organic or inorganic)?

Quoting Wikipedia

Avalokiteśvara is a bodhisattva who embodies the compassion of all Buddhas. This bodhisattva is variably depicted, described and is portrayed in different cultures as either female or male.

Thus, the Avalokiteśvara part in its name relates to the Bankai's ability to restructure everything into anything.
The key here are the words bolded above. Avalokiteśvara or Kanon, as I would refer to her from this point on, was known in many-many form. But all of those forms are her.
Things have different appearances, called by different names, but they are all formed of atoms, of matter. From the most simple to the most complicated, they are in core are made of matter.
The bankai's ability is to restructure the matter so that one thing becomes another thing. Or if we are to use Kanon, from one appearance of Kanon to another.

Why is Jewelry Bonney crying after Whitebeard's death?
I saw her crying hard after Whitebeard's death.

She even tried to avenge his death. Given the fact that she encountered Blackbeard so soon after the war, it seems likely that she has grudge on him, as he was the man responsible for Whitebeard's death.
What is her relationship to WhiteBeard?

hey, what chapter is this?

@JTR Chapter 581

Still, it is not clear whether she is crying because of whitebeards death or Ace death.
But as per this theory she is crying because of the Ace's death.
Also you can read this.

Could be true about Ace but this is about Whitebeard's death. Bonney even tried to kill Blackbeard to avenge him. So Bonney might be deeply related to WhiteBeard to do such thing.

@bot but Blackbeard is the one that give Ace to marines.

I have added few links.

Her crying was explained in the Egghead Arc. She was crying because she is Kuma’s daughter and she witnessed via transponder snail cast that her father has lost his personality and converted into a weapon by Vegapunk

I guess this reframes the meaning of the original panels, given the sequence of events (Marineford war -> Bonney goes to the new world for revenge -> ambushed by Blackbeard) one would assume the man Bonney was after was Blackbeard but if she were actually after Vegapunk at Egghead the run in with Blackbeard was just a coincidence

After leaving the marines why did Aokiji join forces with pirates?
Kuzan/Aokiji was once an Admiral of the World Government. After he lost in the battle for the Fleet Admiral position he left the marines and wander around on its own. And eventually a shocking news shock the World Government. Kuzan joined forces with

 Blackbeard pirates

which is regarded as a traitor to the government when he abuses his position as a Shichibukai.

Question: Why did he joined forces with the pirate group which is a traitor and a threat to the government? Does he not believe in justice anymore in the World Government?

While we don't have a strict no spoiler rule, please try to keep spoilers out of the title, especially for very new plot developments.

The reason is too unpredictable as there's too many probabilities.. We don't know the back story of it. It could most probably be that Aokiji has the intention of destroying the Blackbeard pirates from within by becoming a member. Or he must have accepted the Blackboard ideology. Or he decided to study the group's activities more closely (helping the Government as a spy). We won't have a clear answer for now.

Thanks for the reminder  @ʞɹɐzǝɹ. Sorry its my first time to post spoiler question here. I edited it and will take note of it next time I posts a spoiler question again.

he is a sleeper agent. . . because you know, Lazy Justice.

I think aokiji is part of the revolution army and went in to the navy to spy
also I dont think aokiji really lost the fight,cause just because he lost the fight doesn't mean he would leave the navy, also when he showed at punk hazard he was pretty calm and told the navy not to tell anyone that he was there. I think aokiji purposely losed the fight to join blackbeard and spy that is all.

Welcome to [anime.se]. Thanks for contributing an answer, but could you add some references to back up your answer? Posting a personal theory is okay if they can be backed up by canonical source. Note that you can [edit] your answer to improve it. Finally, consider taking a quick [tour] to know more how this site works.

Aokiji might have his own self justice principles.  As he has previously seen the unjustice rendered by the present fleet admiral to the innocent people of Ohara when Aokiji and Akainu are fellow comrade Vice Admirals in the buster call operation, he might feel indignant to work under a person (Akainu) who has the pretence of killing innocent in the name of justice as they contradict with his own self justice principles. So he might have decided to join hands with Black Beard who proclaims his evil intentions to the world rather than pretending to be someone.
But why he joined hands with Black Beard is the mystery.  Maybe Black Beard might have given him an approbation of making Aokiji the Fleet Admiral after he himself took the world dragons under captives and make Black Beard himself the new World Ruler. Simply a cruel, arrogant person is more detestable than a cruel, friendly person. Or he might be sick of the marines' overall cruel operations to safeguard the world government who follow tyrannical measures.

How do inanimate objects eat devil fruit?
Devil fruit users gained their powers by eating the devil fruit. But how did these inanimate objects gain their power?
This is Luffy, eating a devil fruit before he became a rubber man.

And this is Lassoo, one of Mr.4's guns that became a dog. How did a gun ate it?

I have read that Dr. Vegapunk's research has led him to devise the method that lets an inanimate object (such as a gun or a sword) gain the effect of a Devil Fruit (although it has not yet been shown how this is done)

This means that maybe black beard is able to use two devil fruits because one of them was consumed by an object he uses, maybe a ring, his sword or his gun

As mentioned in the comment, Dr. Vegapunk's scientific expertise is the logic behind an inanimate object being able to "consume" a devil fruit.

Dr. Vegapunk covered exactly how Devil Fruit powers are transferred over to a user, and was the scientist behind the method of adding Devil Fruit powers to inanimate objects, such as swords and guns.Source

This is the only known research paper of his related to this experiment:

The inanimate objects who have eaten Devil Fruits are:

Mr. 4's  gun, Lassoo
Spandam's sword, Funkfreed.

It is also notable that the only Devil Fruits shown to be capable of achieving such a feat are Zoan devil fruits. It may be because Logia and Paramecia only grant the users supernatural powers, which would not bring the objects to life.
This is all that is known about the matter.

According to Oda, a "certain professor" will explain the complex mechanisms behind all of the Devil Fruits in the series in the near future. Source

Perhaps this is the most accepted explanation as for the moment because nothing is completely revealed yet.

Also, Smiley was an inanimate object, which ate a devil fruit

Can Chopper's rumble ball be used on other Devil Fruit users?
We all know that chopper was able to extend the capability of his devil using his rumble ball. But I wonder if other DF users can also use this rumble ball.

While it doesn't look like anyone else has tried the rumble ball that Chopper created yet, modifying your devil fruit power through science is possible.
The One Piece Wikia on the rumble ball has it written:

Through his development of the Rumble Ball, Chopper is the first Devil Fruit user to artificially augment his Devil Fruit powers. However Chopper is not the only one to do so, as Caesar Clown (by his own admission) used his chemical and scientific expertise to artificially augment the Gasu Gasu no Mi to grant himself new offensive abilities.

While the Wikia also implies that the Rumble Ball can enhance any Zoan type, I have not seen this evidenced by anyone else's use in canon sources.

Who is Lola's mom in the New World?
During the Thriller Bark Arc Lola mentioned to Luffy that her mother is in the New World and indicates that she is a extremely powerful pirate. She even left Luffy a vivre card that if ever he runs into any trouble he could ask her 'Mama' to help him out.
Who could possibly be this extremely powerful pirate Lola's mother?

She might refer to Big Mama when saying It's Mama's vivre card back in thriller bark arc. Tamago and Pekoms refer Big Mom as Mama too. Lola might not refer Mama as her real Mom imo.

We know nothing about that as of this writing, but there has been a widely circulating theory for a while now that Big Mom is Lola's mom. You can read about it on various sites. I'll list a few points made in support of the argument on Reddit

Firstly, for those that don't already know the theory, it is that Big Mom is Lola's mother. Back on Thriller Bark Lola gave Nami a vivre card with Lola's signature, saying her mother is a pirate in the New World. People believe this mother is Big Mom because:

Big Mom's name is Big Mom, ie, she is known as a mother.
Big Mom is in the New World
Big Mom's jolly roger has big red lips and the same colour hair as Lola
Nami who has Lola's vivre card just happens to be on the ship that is being attacked by the Big Mom pirates
Nami is likely to eventually pull out the vivre card that Law gave her and accidentally pull out Lola's card instead.

Here is the similarity between Big Mom's jolly roger and Lola's face:

Another few points made in the Wikia are:

Big Mom is in the New World and thats where Lola was born
Lola's crew also said that her mother was an extremely powerful pirate which is another connection between the two
Luffy will definitely meet Lola's mother on account that the crew was given her vivre card and it only makes sense that Luffy meets all members of the Yonkou

Lola's crew stating that Lola's mom is an amazing pirate:

Another popular theory recently is that her mom is Miss Bakkin
The arguments in support of these here are:

Miss Bakkin is the first pirate woman to be introduce for a while and she is a mother which is really rare in One Piece, since all mothers are dead.
Miss Bakkin and Lola have the same hair style, Weeble has the same type of hair braids, Lola’s mouth looks similar to that of Miss Bakkin.
Bakkin also claims to be Whitebeard’s lover, while Lola has been desperate to find a lover herself. Is she possibly trying to imitate her mother?
The other connection to Lola is Thriller Bark itself. Lola’s reason for being in Thriller Bark could have been a search for Hogback. Maybe Weeble needed a doctor and they thought Dr. Hogback could help them. This would explain the stitches on his face, around his neck, and his arm.

Similarity between Lola, Miss Bakkin and Weeble:

Obviously, this is all speculation at this point and we won't know who her real mom is unless revealed by Oda himself. Although, based on these theories, it's likely that it's either going to be Big Mom or Miss Bakkin.

Thanks. This is a great answer. Anyway my bet is 'Big Mam' as many others do. :)

@bot, as far as I know, yes. Accepting an answer only has to do with the questioner. If you feel satisfied with this answer, then yes. Also, no problem :). Even I think it's Big Mom.

You can read about accepting an answer here

Well.. I asked the question before the truth was revealed so I think no one here will complain if I accepts an answer based from speculation. Anyway if the truth will be revealed sooner I will update the question with answer to make it trustworthy question and answer.

@bot, you should rather update my answer. Answering the question in the question itself is not encouraged. You can choose to post another answer as well. Most likely, I'll update this answer myself when the name of her mom is revealed.

Ok then. Maybe you could just put UPDATE below your answer right now if the truth will be revealed to distinguish your old answer from the new.

Its been Revealed.

@Ryan Thanks for the update. I'll update the answer in the next 2 days

It's Big Mom, confirmed in chapter 835

Manga chapter 835 page 20
Chapter 835 shows both parents

Please don't link to scanlation sites, and please don't leave answers with just a link in them and no explanation.

As @Torisuda stated, please explain the above picture with regard to the asked question, rather than just posting a seemingly unrelated picture.

What was that giant shadow with the glowing red eyes at the end of the Thriller Bark arc?
At the end of the Thriller Bark Chapter 490 in manga and episode 381 in anime. I noticed strange giant shadows with glowing red eyes at the background. What could it be?
Check this image in manga:

In Anime:

It's florian triangle monster

As stated in the comments, it's an entity related to the Florian Triangle.

According to Kokoro, many pirate and commercial ships mysteriously go missing every year and, sometimes, a ship will be found sailing without any people aboard. It has also been said that there are many haunted ships with dead bodies sailing across the sea (though, it is revealed that all this is attributed to Brook).

Though, some of the disappearances that have happened in the Triangle can be attributed to Moriah's scheme. Ships have been disappearing mysteriously in it for a long time before he came on his ship, Thriller Bark, ten years before the series. This mystery is confirmed by an unknown ominous entity larger than Thriller Bark that was barely seen by Captain Lola through the fog. It is so large that it completely dwarfs Thriller Bark, the world's largest pirate ship, in sheer size, possibly making it the world's biggest creature to appear in the series thus far.

It may also be possible that it's the trope "Real After All":

If an episode revolves around a haunting (or alien visitation) (or lake monster sighting) (or whatever) that turns out to be a hoax, the episode will end with a shot of a real ghost/alien visitor/lake monster/whatever.

However, knowing Oda, that is highly unlikely. I just stated it as it is possible that we may never get to know what those entities were.

For all that, it looks uncomfortably similar to the shadows from sky islands. (you are right though)

@Kaine Which shadow from sky island? The only one I remember seeing is Klabautermann. It's seen around 3 years since I watched it, so I seem to have forgotten..

The shadows are not on sky island but shadows of people on sky islands visible in fog that appear gigantic due to the distance. They appear just before the sky island arc and there happens to be one in the most recent anime episode. There is a flashback of Bellamy seeing Luffy in one.  When first introduced though, these shadows were interpreted to be gigantic terrifing unidentified beings.

I think that these shadows are other elephants like Zunisha http://onepiece.wikia.com/wiki/Zunisha

What makes you think that? I can similarly think something else than provide a link. Please substantiate your answer.

Zunesha's design was based on the painting The Elephants by the surrealist painter Salvador Dalí; its SPECIES name read backward is "ダリノエミタイナ象", which means "Elephant resembling Dalí's painting".
In Dalí's painting, we can see two elephants with the same Zunesha characteristics. It's easy to imagine that big shadown is about another Zunisha species.

I think that the triangle is related to Enel. My theory goes like this:
Birka is exactly over the triangle and because of the deepflying Sky Island, there is always that mist. The shadows in the background are people of that Sky Island who survived Enel's genocide. Enel came to Skypiea 8 years ago (10 after time skip) — maybe he left Birka around the time when Moria arrived. Before that, Enel killed with his Devil Fruit all travelers either to train his power or by mistake (with attacks like Raigo's). That covers the 3 problems:

the mist
the shadows at the end, and
the missing people before Gecko's arrival.

If the government wants to hide what happened during the void history why won't they just destroy the Poneglyph stone instead?
The world government has been chasing Nico Robin for reading history of Void Century on Poneglyph stones. But why won't they just destroy it so the problem is solved?

I don't read One Piece, but I guess it's natural to keep them for historical reason, and for future research.

I don't think government has this reason. As clearly they are against research and studies regarding Poneglyph stones to hide the history during Void Century. A good example is how they annihilate the whole island of Ohara for studying these stones. Only Nico Robin is the survivor that's why she has a high bounty when she was still a kid.

According to wikia, Poneglyph is indestructible.

The blocks have no real power themselves, apart from their indestructibility; it has been stated that not even explosives could leave a scratch on these stones. However, the words they contain have the power to change the world.
Each one tells a piece of history long forgotten. This history
includes mentions of (at least) three weapons of mass destruction:
Pluton, Poseidon and Uranus. There are two types of poneglyphs: those
that carry information about how to reach the other poneglyphs and
those that carry the records of the "True History". Only when the
stones are read as one will they fill in the Void Century of the
world. In the eyes of the World Government, they are dangerous
artifacts and despite declaring the stones dangerous because of the
weapons, the reality is that the ideals of the fallen Kingdom written
on some of the stones are far more dangerous then any of the weapons.

Because the Government stated that Poneglyph are dangerous artifacts and the blocks also indestructible, the Government prefer to kill peoples in Ohara rather than destroy the Poneglyph.

Which is the most powerful summoning (effective and efficient)?
I have been a great fan of Naruto for a long time, And I have seen lot of animals being summoned. But its been very hard for me to think which one of the summoning is the most powerful?
Please provide manga episode number or anime. I would like to check it again.

How do you define 'most powerful'? this looks like it could be opinion-based

First thing first, I personally don't want to include summons from Summoning: Impure World Reincarnation Technique in my list because hundreds of dead peoples were summoned by this technique. One more thing, Tailed Beasts are not included in my list because Summoned beasts are generally animals bonded with a ninja. As ninjas can summon beasts they are sealed with, the beasts can also summon ninjas. If we look at tailed beasts, they are not animals, they are a pure form of chakra, they are immensely powerful and hard to summon and bond with. This makes them not in the Top 5 list.
Top 5 strongest summons in Naruto's universe
5 - Fukasaku / Shima aka Two Great Sage Toads

(source: nocookie.net)

Summoner: Jiraiya, Naruto Uzumaki
Manga Debut: Volume #41, Chapter #375
Anime Debut: Naruto Shippūden Episode #127
What makes it Top 5: Extremely proficient in the use of elemental techniques that require the nature manipulation of wind, fire, and water.

4 - Gamabunta / Aoda / Katsuyu

(source: nocookie.net)

Gamabunta
Summoner: Jiraiya, Minato Namikaze (Fourth Hokage), Naruto Uzumaki
Manga Debut: Volume #1, Chapter #1
Anime Debut: Naruto Episode #1
What makes it Top 4: He successfully hold the Nine-Tails down while Minato transported it outside of the village using his Flying Thunder God Technique.
Aoda
Summoner: [Sasuke Uchiha][17]
Manga Debut: Volume #66, Chapter #633
Anime Debut: Naruto Shippūden Episode #373

Katsuyu
Summoner: Tsunade (Fifth Hokage), Sakura Haruno
Manga Debut: Volume #19, Chapter #169
Anime Debut: Naruto Episode #95
What makes it Top 4: Katsuyu's clones can attach themselves to injured people, allowing its summoner to channel their chakra through it to heal the injured person.

3 - Nagato's Giant Multi-Headed Dog

Summoner: Nagato, Unnamed Fūma Clan Ninja (Male Animal Path), Ajisai (Female Animal Path)
Manga Debut: Volume #41, Chapter #375
Anime Debut: Naruto Shippūden Episode #131
What makes it Top 3: Physically strong and resilient, it gained additional heads every time it splits or been struck, and each duplicated head carried the black receiver and the Rinnegan like the original.

2 - Monkey King: Enma

Summoner: Hiruzen Sarutobi (Third Hokage)
Manga Debut: Volume #14, Chapter #120
Anime Debut: Naruto Episode #71
What makes it Top 2: He was easily able to incapacitate a reincarnated Hashirama and Tobirama Senju in brief hand-to-hand combat when they tried to keep him from transforming under the command of Orochimaru.

1 - Demonic Statue of the Outer Path

Summoner: Hagoromo Ōtsutsuki (Sage of the Six Paths), Madara Uchiha, Obito Uchiha
Manga Debut: Volume #29, Chapter #254
Anime Debut: Naruto Shippūden Episode #10
What makes it Top 1: Possesses great strength. The Demonic Statue can emit phantom dragons formed out of absorption chakra, which is capable of extracting the chakra of anyone they come in contact with. Most important, the Demonic Statue is also capable of emitting chakra chains from its mouth, which binds the power of tailed beasts, and can be used to both extract them from their jinchūriki and quickly seal them inside the statue.

*Most information was taken from Narutopedia.

I am not satisfied with your analysis, even if you state it like that Hanzō single handedly  won over  Jiraiya,  Tsunade and  Orochimaru with salamander.

@AnkitSharma Yes, Hanzō's signature summon, Ibuse is indeed strong.  Ibuse has great amount of strength, and is able to release poison mist from its mouth, making victim's body entirely numb, eventually fatal. But the fatal weakness of Ibuse is it's slow, and obtuse.  Each summons of Sannin is agile and fast, except Katsuyu. Though she is slow, but she can still regenerate by consuming Tsunade's chakra even though she inhaled the poison gas.

I guess the demonic statue of the outer path aka ten tails husk should also be a chakra (as you mentioned that tailed beasts are chakra themselves). So, it should not be an animal itself.

As tailed beasts can be summoned too, I believe the most powerful summoning animal will be the ten tails.

@Jeethu I have a doubt with the shiki fuujin tho. I also posted a question regarding it: http://anime.stackexchange.com/questions/27424/is-shiki-fuujin-a-summoning-jutsu

Are there ever any animals featured that aren't Pokémon?
Out of the Pokémon episodes that I have seen, I do not remember ever seeing an animal that wasn't a Pokémon. I have also not heard of animals being present in Pokémon.
Which lead me to wonder: Are there ever any animals that aren't Pokémon present in any episode or Pokémon manga?

See also http://scifi.stackexchange.com/q/127252/4918 "Do regular animals exist in the Pokémon universe?" on Science Fiction & Fantasy SE.

In Gastly's Pokédex entry for Fire Red it states

a being that exists as a thin gas. It can topple an Indian elephant by enveloping the prey in two seconds.

Fish are also seen in the episode Pokémon Shipwreck:

When researching to see if there has ever been an animal featured that isn't a Pokémon in a scene or Manga I came across this on Bulbapedia's article Animals in the Pokémon world:

Real-world animals have been mentioned a number of times to exist in the world of Pokémon. Most often, they are mentioned in relation to a Pokémon category. For example, Pikachu is known as the "Mouse Pokémon" and was directly referred to in the anime as an "electric mouse", hinting that real-world mice exist in the Pokémon world. Other than this, all other mentions of animals are rare.

There was also this image:

Which clearly shows a dog. However, this is the only image I could find of an animal that isn't a Pokémon.

Actually, "electric mouse Pokémon" doesn't exactly imply there are real-world mice in-universe. Pikachu isn't the only mouse Pokémon, and also not the only electric one. Saying "a Pikachu is a mouse Pokémon", would be like saying "a Labrador is a dog animal". It's kinda redundant, but it doesn't really have any deeper meaning to it either.

There's a pretty comprehensive list of animal occurences in pokemon on Bulbapedia here.
Examples:

In "Ash Catches a Pokémon" Pidgeotto is seen eating a regular worm
before being captured by Ash.
In "The Water Flowers of Cerulean City" fish can be seen in the fish tanks inside the Gym
In "Battle Aboard the St. Anne" a cooked lobster can be seen as food served on the ship.

Several examples exist in early episodes. Shortly before Ash catches Pidgeotto, it eats a worm, possibly the smallest non-Pokémon animal the anime ever showed. References to such species lasted longer than their appearances. In a much later episode, Ash mentions catfish.

On the Pokèmon card Inkay (069/198) rapid strike, it is holding a roll of cheese. This has a picture of a cow on it.
ALSO, on the Peony 150/198 supporter card, there is a wood carving of (reindeer, mouse, caribou, or something) next to the closest house.

Hi, I'm a bit curious why you deleted your previous answer. Note that you can always [edit] your post to add more details.

In season 1 episode 20 there is this, I don't think it's a Pokémon, but can't say what animal this is:

I was thinking of the very same episode, it's a mongoose which is snakes' natural rival

In one of the episodes in the indigo league they eat muskrat kebabs and say themselves it's muskrat. Don't know which episode though

Does the title of Bobobo-bo bobo-bo mean anything?
Bobobo-bo Bobo-bo (ボボボーボ・ボーボボ) is certainly a strange anime, but does the title mean anything?
The main character's name is also Bobobo-bo Bobo-bo (Bo-Bobo for short - but not Bo).
Some of the other names in the series are jokes - there is someone called Beauty and another called Don Patch (a pun on "donpachi", the Japanese sound of machine gun fire).
Is there some joke in his name (apart from the obvious absurdity)?

Bōbō (ぼうぼう or ボーボー) is a common phenomime (non-auditory onomatopoeia) expressing excessive growth of things such as weed or hair, growing all over the place and unkept. The originally planned title was Hanagēbo Bōbobo (ハナゲーボ・ボーボボ), with hanage being nose hair as you may well know. This was scrapped because although Bo-bobo uses his nose hair extensively, his is not exactly growing "all over the place". But the author wanted to keep the phonomime in the title, and ended up with the final title.

Could you link to external citations/references to support your answer?

What order should the Fairy Tail volumes/chapters be read in? And how to read labelling "Fairy Tail 465 - 400 Years"?
I've watched up to episode 120 of the Fairy Tail anime and want to start to read the manga, while I finish the anime. I'm quite new to reading manga and know how to read them, it's just working out which one is the first one I find difficult.
I would really like to get the first manga (in the story) for a Christmas present but I don't know which one is first.
I started to read what was listed as the first one on a manga website (Labelled as Fairy Tail 465 - 400 Years) to check if it was and ended up reading the spoiler:

 That Natsu is Zeref's brother!

Can someone please help me by telling me which manga I need to read first and what is the order of the others?
And
If possible, Can someone explain the labelling "Fairy Tail 465 - 400 Years"? so that I know what to look out for in the future, to prevent spoiling it for myself.

You should read the chapters in order from Chapter 1 to the latest. On the majority of the websites they will put the latest characters (based on chapter number) towards the top of the page.
As for your second question: Fairy Tail 465 - 400 Years; means the that is chapter 465 of the series, and the title of that particular chapter is '400 years'.
As an FYI to you, there are several other Fairy Tail series that are pseudo-canon (or fully canon) related to the main story. Some of them are written by the same author of the core series. Just be warned that some of them have spoilers for historic events of the main series, but they are all really good.

Why are ghouls' eyes red?
Is there a particular reason why ghouls' eyes are red? (called 'kakugan' based on my research).

There might be a reason provided by the writer, which I cannot research as it may only be available in Japanese. (I am thinking that it may be due to the color of blood?)

The kakugan are red due to the activation of RC cells in the ghoul's body. The RC cells are present in their bodies are when they activate them to use their kagune of due to them becoming excited, the kakugan activates as well.

A kakugan is an influence of activated Rc cells.

The kakugan are red as the RC cells are red in colour.

Rc cells (Red Child Cells) are certain cells that exist only in the story of Tokyo Ghoul. The origin of the name comes from how each individual cell looks like a curled up foetus.

What is the Gundam anime and movies and OVA order?
There are a lot of Gundam anime series, movies and OVAs, so I don't know where to start.
Can anyone tell me its order to watch it?

There are 6 different accepted universes within the Gundam Multiverse.
Each has its own characters unique to its timeline, and does not intersect with any other timelines (ex: In Gundam Wing, the events from Mobile Suit Gundam never happened).
They are listed as follows:
Universal Century Time line (Best place to start to get into it, every single Gundam series out there is rooted in characters/gundam from this time line).
In order they are:

Mobile Suit Gundam
Mobile Suit Zeta Gundam
Mobile Suit Gundam ZZ
Char's Counterattack
MS Gundam 0080: War in the Pocket MS
Gundam F91 MS Gundam 0083: Stardust Memory
MS Victory Gundam
MS Gundam Unicorn.
Turn A Gundam (This series is really good and is a huge shift in focus from prior gundams. Its set roughly 1000 years in the future, and Turn A is quite possibly the most powerful Gundam in the entire Gundam franchise).

After Colony Timeline This is probably where most people are introduced into the Gundam world. A group of space colony scientists build Gundams piloted by young boys in hopes of weakening Earths oppressive Government.

Gundam Wing
Endless Waltz

Cosmic Era Timeline If the Universal Century seems to "old" for your tastes, this is a great place to jump into Gundam.

Gundam SEED
Gundam SEED Destiny
Gundam SEED MSV Astray
Gundam SEED Stargazer

After War Timeline Welcome to your post apocalyptic Gundam universe. Basically the series take place after a giant colony is dropped on Earth, wiping out almos the entire population.

Gundam X

Future Century Timeline Instead of giant wars and colonies fighting one another, rulers are decided by a Gundam tournament that occurs every 4 years.

G Gundam

Anno Domini Timeline Several factions are constantly vying for power when a mysterious group known as Celestial Beings creates Gundams that are years beyond an current MS technology.

Gundam 00

That concludes our journey through the very bumpy Gundam multiverse lane. I left out a few movies and tv specials, but I think I captured the bigger picture here. Now go forth, and become Gundam maesters!
The above was found here.

Your UC does not appear to be in order, for example according to another page in the wiki 8th MS Team is UC0079 and far away from Unicorn in UC0096. I would also add The Origin and probably Gundam Reconguista in G to UC. There are also the Advanced Generation and Post Disaster (and Correct Century¿?) timelines, which you probably have missed. The page is really long. :\

It's difficult to know the exact order when different sources say different things :/

Why did Rem kill L?
I know that it was Light's plan to make Misa look suspicious again so that Rem would kill L. But why did she think that Misa was going to be executed?
Was it because her lifespan was shortened again?
I thought that only a Death Note can shorten the lifespan of a person, and even though she did the Shinigami eye deal again, was her lifespan too shortened?
Or can your lifespan get shortened by other people, because of their actions?

Basically, L told her what would happen, when she would be caught. Light made it pretty obvious that Misa was the new Killer, letting all evidence point in her direction. He made her kill people the instant she left the mansion. Especially since Misa was the original suspect for being the second killer. If it wasn't for the fake rule, Misa would have been arrested or at least thoroughly investigated and L had doubts about that rule from the beginning anyway.

L:
  If the murderer by notebook is recognized, at the very least, if we cannot get the capital punishment, we would have them write their own name in the book. That's how it is. chapter 57

Rem, being pretty sharp herself, came to the same conclusion. She knew L would figure it out, she knew it would mean the end for Misa. Though, she had made a promise to protect her till the end, so she knew she had to kill L to prevent Misa from dying early.

Rem:
  The one who is killing the convicts right now is Misa. There is no doubt about that. Since the notebook has been revealed, no matter what happens from this point on, the one who will be caught as Kira will be Misa. That wont change...
  Yagami Light is confident that I will save Misa's life... The only way to save Misa in a situation like that would be for me to write Ryuuzaki's true name in the notebook...
  And in that situation if I were to kill Ryuuzaki then I would have clearly meddled with Misa's lifespan and die. chapter 57

This is for me the weakest play from any character in the series. I've searched through the internet to see if someone had the same thought that I did but haven't found any mention to it.
Rem wants to protect Misa
Rem needs to be alive to protect Misa
Then, Rem can't protect Misa if she's dead
With this simple point in mind, what she did was only the last resource she had, a resource that she should of have taken after discarding other ways of action. If she's dead nothing stops Light from killing Misa on his own (which was his initial plan).
Why didn't she talk to L and negotiate? Give him two options:
Option 1 (what she partially did): I kill you, Watari and the whole task force and you'll never catch Kira nor Misa, failing in every aspect of your investigation.
Option 2 (what she could have done before going for Option 1): I tell him that I can see who's the first Kira, and that the second Kira is Misa. But that as a Shinigami who's involved with Misa, I will not let anything happen to her, so I can either kill them all, or give them, in exchange for Misa's innocence), the name for the first Kira. If they refuse this deal, then they will have none (and go to Option 1).
There's a chance L would of rejected this deal, for an ideal about finding through himself who's Kira or an ideal of justice where he wouldn't want Misa to have immunity. But in the face of death, there was a chance where he could see that one of the two options had a better outcome than the other.

Comments are not for extended discussion; this conversation has been moved to chat.

The police suspected Misa of being Kira, and she was about to be exposed. Rem realized that Light had purposely set Misa up to get caught so that the only way to save her would be to kill L, otherwise, Misa would get the death penalty for being Kira. If a Shinigami helps a human by extending their life like this, the Shinigami dies. Even knowing this, Rem sacrificed herself in order to save Misa by killing L and making it so Misa would no longer be a suspect.
Also see: What was the intent for making Rem sacrifice herself for Misa?

to save miss I think. because if watari told L the information he had, then both Light and Misa would be executed.

While this might be correct, could you expand a little bit why they would be executed (by whom?) if Watari told L?

What is the first ever produced anime and manga?
What is the first anime ever produced in Japan?
And what is the first anime film and first anime series produced?
I heard that it was Astro Boy, is that true? And what is the first ever manga produced in Japan?

What is thought to be the first anime was a 3 second clip that is 50 frames long, called Katsudo Shashin. In it, a boy writes 活動写真, which means "moving pictures" on a board. Its creator and date of creation are unknown, but it is thought to be from circa 1907.
There is an anime short from June 1917 named  なまくら刀 (An Obtuse Sword) that is 2 minutes long and a 1918 film adaptation of Urashima Taro, or 浦島太郎 that are thought to be the first films. The Kyoto International Manga Museum cites Imokawa Mukuzo Genkanban no Maki from April 1917 as the first Japanese produced animation, though the Wikipedia article implies that there were previous works.
The first color anime feature film, which is sometimes considered to be the first anime by modern standards, is Hakujaden, which was created in 1958.
おとぎマンガカレンダー, or Otogi Manga Calendar, was the first anime series to be produced and the first to be televised. It ran from 1961-1964. Astro Boy first aired in 1963, making it one of the older anime series, but not the oldest. However, Astro Boy was the first 30 minute anime series as well as the first anime series that aired weekly.

Manga is a little bit more complicated because comics existed and it's hard to draw the line between where something stops being a comic and begins being a manga. Sazae-san was a comic strip published from 1946-1974 that has the longest ever anime series based off of it. Astro Boy is more generally referred to as a manga, and it began in 1951. There doesn't seem to be one specific manga cited as the first manga, though it seems to often be consider to have begun after WWII, as explained in this.
Edit: To add to this, Momotaro: Umi no Shinpei (桃太郎 海の神兵) was the first feature-length anime, which means that, at 74 minutes, it passed the 40 minute mark to be considered feature-length.
Edit 2: Some new information has been added based on information in the Kyoto International Manga Museum

The First Anime
Astroboy's Claim to Fame
Astroboy (1963) is often thought to be the "first anime", but that's false. It does merit some firsts though: it was the first anime to be broadcast overseas, and also the first anime that was broadcast regularly that lasted a full TV slot's duration.
What Astroboy isn't, and the real 'first anime'
The first known animation to come from Japan is Katsudo Shashin. Experts debate its age, but it's thought to have been created between 1907 - 1911. This short clip was likely shown in a private home to entertain guests, rather than be publicly available.

Many of the frames from Katsudo Shashin
This clip is out of copyright, you can watch it on the Wikipedia page

Anime's growth then was primarily attached to live action. Actors would interact with fictional anime characters for a short segment of a show. The most screen-time anime would get would be during advertisements, or occasionally once-off films that were shown as a novelty. The main reason for this is that the production costs for anime were prohibitive if a company wanted any significant amount of time animated.
Another area where anime was being used was in the armed forces. Studies at the time discovered that recruits learned faster and remembered better instructional videos that were animated. With the need to train many troops with the appearance of World War 2, anime became utilized more and more. At the height of the war, the first feature length anime film was produced - Momotaro's Divine Sea Warriors (1945) - a propaganda cartoon for the masses.

Momotaro's Divine Sea Warriors features a lot of military content.

Without significant funding such as the military's, anime was still non-viable for any studios. Several productions were made, including Otogi Manga Calander (1961) - the first anime series to be televised. The exact first tv anime is contestable though - The first televised stand-alone full episode anime Three Tales beat Astroboy by a single year however in 1960. Or a shorter clip (8 minutes) - Mole's Adventure in 1958
Japan wasn't devoid of animation, however. Disney was doing very well in the West and many of their movies were imported to Japan, and did consistently well in the box office. The Tale of the White Serpent was released in 1958 to try and rival the productions of Disney. Toei (the animation studio responsible) had difficultly making a significant profit off film however, and had to support their work with money made from advertisements.

The Tale of the White Serpent was heavily influenced by Disney works, although Toei tried to keep some of its own influence in the drawings

In 1963, Astroboy was released and had great impact on the industry. Osamu Tesuka (Director & Author of Astroboy) made large breakthroughs on how anime was produced and significantly reduced the financial investment required. This probably belongs better in another question, but for a taster some of his innovations included:

Realising that Intros, Outros, "Previously On", "In the Next Episode" segments could be reused - cutting animation time per episode significantly.

Reuse of backgrounds and celsheets, and reducing the amount of movement onscreen also reduced the time to animate each episode. (Fun fact - before Tesuka, animation studios would give fans who showed up to the studio cel sheets because the fans loved them and the studio had no use for them. They're now worth a lot of money)

Thus anime as a viable industry for television was born and more competitors began to appear onto the market.

Flying through the sky at its basics only needs one cel sheet, and a moving background.

Two years later (1965), another Tesuka work made a mark on the world - Kimba the White Lion, the first colour TV anime series to be broadcast to the public.

Kimba the White Lion also used many of Tesuka's animation tricks, such as repeated segments of running.

The First Manga
The development of manga was a gradual evolution from ancient Japanese artworks such as Yamato-e, paintings on folding screens (byōbu) (as early as 646AD), which often told stories when read from right to left.

Depiction of the Battle of Sekigahara from the Edo era
Hikone-jo Bon Sekigahara Kassen Byobu by Kano Sadanobu

There are many different stylistic developments in (byōbu) artworks, but the next relevant stage for manga is the popularization of portable artworks that told stories. Makimono handscrolls. These existed for many years (pre 300AD) but were mostly for written messages at first.
The Scrolls of Frolicking Animals or Chōjū-jinbutsu-giga are attributed by some to be the first manga drawings. These are held in the Tokyo National Museum and consist of several volumes.

The invention of the printing press brought ukiyo-e (woodblock paintings) to the general public.Some historians believe these to be the first manga. These were sold commercially for many years from as the 17th century right through to the 19th.

Ukiyo-e print of the new printing process

Along with ukiyo-e woodblock paintings, other woodblock paintings started to become popular when many of them were bundled together and sold as a set. Kusazoshi picture books (** 1600-1868**) in varying forms (the colour of the cover of the books often indicated the genre/target audience) were now available to the general public as a commercial product. These were primarily written stories with picture accompaniments, but are sometimes regarded as the origin of manga.

the poet Izumi Shikibu - by Komatsuken circa 1765.

With printing came newspapers and magazines, and at certain stage, comics strips began to be printed in newspapers - mostly strips that were sent in from the public. In particular, Japan Punch was known for its political-based cartoons. These were very popular with the public and in 1874, the first comic-strip magazine was published - Eshinbun Nipponchi. These productions are argued by other academics to be the conception of manga.

Cover Page of Japan Punch (April 1883)

As you can see, the first manga is very much up for debate.
Additional Reading
This a very interesting topic and believe it or not, this long post is very summarized. I'd recommend some of the following books to learn more about anime history.

Japanese Animation: East Asian Perspectives (Book, Reference)
Anime: A History (Book, Reference)
A Drifting Life (Manga, Autobiographical)
Starting Point - Hayou Miyazaki (Book, Autobiographical)
How the printing process for woodblock prints worked (Online)

Tetsuwan Atom (1963) is considered the first anime not because it was the first animation from Japan, but because it invented the concept and helped create the anime industry.
But I'll argue that it was only a prototype and that it wasn't until Ursuei Yatsura (1981) that anime became what it is known for today. It invented many of the tropes that are carried on to this day. It also released right on time for home video, which helped reshape the entire industry in its image.
Or if you are looking for the first time Japan produced something one can call "animated"...
Katsudou Shashin (1907)

I wouldn't call this an "anime", however.

Is it possible that marines are also trying to find one piece?
Gol D. Roger said that one piece treasure is there and anyone can claim it due to which it started the "Great Age of Pirates."
After that moment, every pirate set sail to find that treasure and that's how everyone began to explore so many things. During this adventure many fights began and many incidents happened.
Since Marine are the military sea forces and their duty is to maintain law and order. But then I was wondering that:
Are they also trying to find one piece so that they can stop this chaos of finding one piece.

Well, it's not impossible. But to the best of my knowledge, there is nothing saying/hinting that this is the case.

Before I begin to answer please let me state that I only watch the anime, I do not read the manga which is far ahead of the anime.
So the short answer is yes it is a possibility, however the likelihood I believe is very doubtful.
Gol D. Roger started the infamous age of pirates by saying his treasure was up for the taking and ever since then the military has been falling all over themselves trying to round up those pirates; it got to be so bad that they had to recognize some of the stronger pirate groups as "Warlords" who they would not go after for the piracy crimes in exchange for the Warlord pirate group to take care of the lower class pirates running rampant. Admiral Fujitora is personally against the notion of allowing the stronger pirates such as Don Quixote being allowed to do whatever they please and he wants to bring an end to the entire Warlord system.
The show is centered around the Straw Hat Pirates who have taken the world by surprise time and time again for how rowdy and badass they are. They went from defeating a small marine base to taking on the warlords, they went from warlords to storming Enis Lobby and giving a middle finger to the world government, and is if that wasn't bad enough they then took on the Celestial dragons who are considered gods compared to everyone else and then Luffy went and broke into and out of Impel down which just pub stomped the Marines reputation for being able to control the order. The straw hat pirates have made the warlords, the world government, and the pirate emperors their enemies, it is quite literally them vs the entire world.
The government is so busy trying to regain their diminishing reputation that they cant afford to waste time looking for pirate treasure. Remember the war of the great? Remember Whitebeard's last words? Whitebeard reminded everyone that One Piece exists to spark the flame once again because the government refuses to accept One Piece even exists. Imagine the government turning up with One Piece after all of this, it would bring humiliation on them; they would much prefer One Piece never be found and people losing faith in its existence as to make people lose interest in being pirates because the second they get One Piece and word gets out it'll just cause an even bigger wave of pirates but this time they will all be hell bent on going after the Marines directly and before you know it we have another war of the great.
Again this is all speculation and I have just as much evidence to support my theories as does the next guy to reply who says that I'm entirely wrong. From the way the series is going I expect that the main focus will be taking down Kaido and Big mam but we cannot forget about Luffy's wrath for Blackbeard; either way we all know the marines aren't even in the picture, its the pirate emperors that own this series. All it took was Shanks saying stop for an entire war to end, that's how terrified everyone is to piss off an emperor, and Luffy has made it his goal to piss them off. At this point the marines are relics of a lost age.

Actually, after researching a bit I came to this conclusion that is:
 In Episode 485:

Whitebeard tips backward, inhales, gathering his last breath, and
  bellows at the top of his lungs, "ONE PIECE... DOES EXIST!" His words
  echo throughout all of Marineford, and are heard over the Visual Den
  Den Mushi and transmitted straight to the viewing public at Sabaody
  Archipelago. Knowing what impact his final revelation is going to
  have, Sengoku curses Whitebeard.
Sengoku showed great fear and he was furious with Whitebeard because
   he revealed to the entire world about the existence of One Piece.

This shows that Sengoku don't want that one piece treasure should be discovered. He knew that after what Whitebeard said all the pirates will go mad and start searching for one piece and everyone will believe in Whitebeard words. But why he cursed him ?
Let us see the ideology of Sengoku regarding one piece:

Though he may appear to be stern because of his duties as a Marine, he
  is actually kind and compassionate. His drastic actions at the Battle
  of Marineford were motivated by the desire to protect innocent
  civilians from getting embroiled in conflict out of fear that
    when the
   secrets held in One Piece are discovered, it would turn the world on
   its head and lead to total war.

So actually, he wants to protect innocent civilians from pirates. He knew that if one piece will be discovered then it will lead to war and only innocent people will suffer. So by that he actually want one piece to be not discovered at all.
So in short for the sake of innocent people they didn't try to find one piece and focused on protecting them from pirates.
According to my hypothesis, if they will be able to find one piece and if pirates come to know about this news that one piece is with marines then for sure every pirates of that world will charge against those Marines just to get one piece and then you can just think how drastic situation it will be. There will be a huge battle and again innocent people will suffer.

What was Izumi doing in the Central City railway station?
While watching ep. 9 of Brotherhood, I noticed that when Winry came to Central City railway station and started looking for someone, Izumi and her husband were walking behind her:
Picture from FMA brotherhood.

After that I tried for this scene in the 2003 series, and in ep. 23 I have found this scene where they were reading something at the Central railway station:
Picture from Anime FMA 2003

So my question is: what might Izumi and her husband be doing there? Do they usually travel like this, or might there be any sort of work they had to do there? Is it also possible that it is an error (like they didn't want to put those characters there)?

Izumi was looking for Ed and Al. She had been hearing rumors that they had joined the State Alchemists and become dogs of the military.
In the 2003 anime we see that Izumi and Sig are talking to Mustang before Ed, Al and Winry leave Central. At the end of Episode 26 the two have caught up to them in Rush Valley. If I recall correctly, in the next episode Izumi reveals that she came after them to "re-educate" her wayward students.
The Welcome to Central City poster that we see Izumi and Sig look at to me looks like a directory of sorts. You see Izumi is looking at a list so she is probably looking up places to search.
I would assume it's the same in Brotherhood (I can't remember exactly if their reunion was the same) because in both series Ed has made a name for himself as a State Alchemist and in both Izumi shows her dislike towards the military. There is no doubt she would hear about the "State Alchemist and Hero of the people Edward Elric".

If I'm not mistaken, in the manga, the brothers seek out Izumi themselves. Not sure if Izumi was trying to find them prior to their actual reunion, or if she and her husband were just travelling and we were just given a cameo or Easter egg. (Seeing how she first met the brothers while travelling, the latter isn't implausible.)

Why shadow clone technique make a clone of what they are holding?
Definition : Similar to the basic Clone Technique, Shadow clone technique creates copies of the user. However, these clones are corporeal instead of illusions.
According to me when Naruto uses Shadow clone technique then his whole dress also get cloned to other user, so there might be possibility that item inside bag might get cloned too.
And it can also be proved as he uses All direction shuriken technique where "Naruto and his shadow clones throw shuriken all at once." - Source
So the quesion is: How non-living object get multiplied because according to wiki definition about Shadow clone technique : "The user's chakra is evenly distributed among every clone, giving each clone an equal fraction of the user's overall power." but non-living object has no chakra so how come ?
If it is possible to use it which is true, then let us say that those cloned user threw kunai on the target then for sure it will get hit on that target. But if that cloned user (which uses that kunai) got vanish then :
Will that kunai too vanishes at that same time or it will be there as it is?

Normally what the shadow technique can do is hold back an idem with their shadows or manipulate them. I'm not sure if it can do more than that.

Well, obviously they are able to clone the equipment, as all the clones use the weapon, but actually I never understood it, because, if think logically, you can clone only the thing that has chacra, but clothes and weapon don't have it.

I'd go with the out-of-world explanation: if he can't clone shuriken, he shouldn't clone his clothes either, and mass nakedness shouldn't be a feature of his principle attack--just for jokes and special situations.    For in-world mechanics, no idea, there are very, very few such explanations for anything in Naruto.

Well we have seen Hiruzen Sarutobi's shadow shuriken technique,it explains a lot that chakra can be used to create anything,it's easier to make a copy of something although.

Because, Magic!

Short answer: If you enjoyed it, don't question the logic.
Longer explanation
This is an example of Artistic License, which means the author is allowed to ignore logic if it makes the story more enjoyable.  The trope of a character's ability extending to their equipment is known as My Suit Is Also Super on tvtropes.1
Cloning techniques in Naruto require this trope due to how it is usually used: to confuse, distract and deceive the opponent. Cloning based techniques would be useless if the opponent could tell the original apart from the clones by simply looking at who has a shuriken in hand!2
Artistic License requires Willing Suspension of Disbelief from the audience. This is acceptable to the audience since they want the story to entertain, and do not necessarily want it to be logically accurate. The author should maintain a balance between the Artistic License and the Willing Suspension of Disbelief that the audience is willing to give.
If he uses too much Artistic License, the audience cannot take him seriously anymore. For example, if Naruto had awakened Mangekyou Sharingan, and it was explained with "an Uzumaki can awaken Mangekyou Sharingan by repeatedly using Shadow Clones and Rasengan", then the audience will lose interest in the story.
It he uses too little of it, an opportunity to make the story more entertaining is lost. The author would have had to exclude a lot of techniques and events from the story, which would make it too boring.

1 The trope of cloning techniques extending to the user's clothes is Magic Pants is used mainly for censorship reasons, as otherwise the clones would end up naked. It is too much trouble for the author to keep dealing with all the time. Given how often the cloning techniques are used in the story, it would also get annoying for the audience after a while.
2 Interestingly, in a much later battle, Kishimoto plays with this trope differently. Naruto makes one of his clones carry a certain thing which fools his opponent into thinking that clone is the original. See the below spoiler for details.

 During the battle against Kaguya Otsutsuki, Naruto deliberately places the Gudodama behind the back of one of his clones, which tricks Black Zetsu into thinking that clone is the original.

There exists shadow clone jutsu for Non living objects, See http://naruto.wikia.com/wiki/Shuriken_Shadow_Clone_Technique. Yin and Yang energies are extremely versatile, and can do just about anything so long as its not elemental.

Why is adult anime so much less likely than US adult animation to be comedic?
This video explains why US adult animation is almost always comedic. US animation studios transferred their efforts to television in the years following Hollywood's anti-trust case (which meant future shorts were less likely to be assured of theatrical releases), but this was only cost-effective if the animation style was simplified and the content made child-friendly enough for extensive ad-heavy re-runs. With the exception of a 1972 series, adult TV animation waited until The Simpsons. Although this series was a risky investment, lessons learned from its rapid success allowed a transition from expecting adult animation to be unviable to expecting it to be viable as long as it was comedic, preferably in a sitcom format.
Clearly, adult anime is in a very different situation and has been for decades. (One need only look at the lists here.) The reason, in short, is that the historical factors mentioned above are unique details of US history. A similar overview of the history of Japanese animation, both cinematic and televisual, would sound completely different and make sense of the diverse range of adult anime that resulted, including in the present day.
So my question is: what are the key details of that history? (If it's an inappropriate question here, I might move it to History.SE instead.)
Edit for requested clarity: I'm referring to work with an adult target audience, without specific implications of sexual or violent content (though these could well apply in some cases).

In my view, serious animation in Japan has evolved from such works like studio Ghibli's classics and series which were supposed to resemble western soap operas and dramas, and shows which are basically propagandas of healthy way of life, social adaptation, acceptance and patriotism. And to be taken seriously, they had to drop the funny act. That's one thing that comes to my mind.

The Simpsons is an animated prime time sitcom and is targeted not at adults specifically but at families. In this respect it's just like The Flintstones, another US animated prime time sitcom that originally aired in 60's. It's not really all that hard to find animated TV series in Japan, that are very popular, comedies and targeted at a broad family audience just like The Simpsons. Crayon Shin-Chan for example, is often compared to The Simpsons, because of the similarities between its titular character and Bart Simpson. Another example is the show that airs before it, Doraemon.

Perhaps the only long running anime that's similar to Simpsons that I can think of is Sazae-san. I don't know if it's comedic enough since I don't watch it though, but I believe both are family-oriented as Ross mentioned (compared to Doraemon, which I believe is more children-oriented anime). On the other hand, I think I can safely say that long-running, family-oriented anime/cartoon tends to be comedic.. otherwise, there's no plot and no entertainment value.

Do people who use the Death Note become Shinigami themselves?
In both the Death Note manga and anime, it is stated multiple times by Ryuk that once you use the Death Note, a human can go to neither Heaven nor Hell.
However, it is hinted in an additional movie that encompasses part of the anime that Light was reincarnated as a Shinigami.
Is it then possible to say, that any humans that use the Death Note do not go to Heaven nor Hell because they go to the Shinigami Realm?

No.
Humans who die don't go to Heaven or Hell (because neither exists).
They go to Mu (Which means, nothing).

Death Note, Volume 12, page 188, has these two rules in regards to
  "Mu": "All humans will, without exception, eventually die." Also,
  "After they die, the place they go is MU (Nothingness)."

Basically, there's nothing after death. Shinigami are a different species.

On the other hand, it's worth noting that every single person who has used the Death Note has died.

That's also stated by Ryuk. The fate of every Death Note user is the same. The Shinigami originally owning the Death Note will write their down in the Death Note, and they will die. There is an exception to that rule. Misa Misa didn't die at the end of the series.

It depends on which ending you go with.  I believe the anime she lived, whereas in the manga, it is at least stated that she died.

Do apples grow on trees in the Shinigami realm?
In the Shinigami realm, there are other apples, that taste like sand, according to Misa Amane. Do these apples grow on trees in the Shinigami realm?
I think they may rather grow on a plant, close to the ground, because of the sandy taste. But I'm not sure whether there really is ground in the Shinigami realm.
I've also heard that nothing grows in the Shinigami realm.
Is there anything known about this? In the anime, there are not much scenes from the Shinigami realm.

From Death Note wiki

Apples from the Shinigami Realm look like shriveled green peppers and do not resemble normal apples at all. Misa gave a juicy human apple to Ryuk and in return he lets Misa have a bite of an apple from the Shingami realm which Ryuk was carrying with him at the time. Misa takes a bite of the apple and then spits it out in disgust saying that it "tastes like sand".

It is not mentioned either in the anime or manga, whether these grow on trees or not.
It is mentioned though that

Apples have become a very popular commodity or currency in the Shinigami Realm when Ryuk returns with an unknown quantity after the end of the series. In the manga one-shot, Midora bribes the Shinigami King with 13 apples she brought back from the human world in order to receive an extra Death Note, which she gives to C-Kira.

Why was the hair of Howl colored black when he was young?
In the beginning-middle of the movie, Sophie accidentally made Howl paint his hair black instead of his natural blonde color. I also suspect that this is his natural color because he felt so upset after the incident.
But if this is right, then why does Sophie see him in the vision in his current color (black) which he got years after that scenario?
Was that an accident in script? Or is there another meaning for that part of the story?

Sophie went and organized his hair coloring products (like he said not to) Howl's hair is naturally black he dyes his hair blonde. When he rushed out of the bathroom this hair was a bright orange because his products weren't in the order he was used to, so by instinct he chose the wrong bottle. When he got depressed because he wasn't "beautiful" his hair turned into it's natural black color.
Because his hair is naturally black, in the vision she saw, his hair is black, not blonde.

How is Goku able to survive in Space?
In Dragon Ball Super episode 13 after losing the Super Saiyan God power, how is Goku able to breathe and survive in space.
As we all know that Saiyans can't breathe in Space then how is he able to continue fighting with Beerus in Space in SSJ2 form?

This is just speculation but I believe Saiyans are capable of breathing in space for short periods of time unlike Freeza who can live without oxygen indefinitely.
Also assuming Super follows The battle of gods movie, Goku could still be within/close to the earth's atmosphere.
Bardock has also been seen flying through space in his special although that was technically filler.
The most likely answer is that it is simply a retcon, Akira Toriyama is known to have a bad memory when it comes to the Dragon Ball universe and so it is likely that he just simply forgot that Saiyans were incapable of doing so.

Goku is indeed still in the stratosphere according to the Dragon Ball Super comics, but a person shouldn't be able to be there for a long period of time though.

Here it is shown that Goku is able to hold his breath for a very long time.

There is also a scene where Vegeta destroys planet Arlia. Vegeta and Nappa are standing in their space pods with the hatch open as Vegeta fires a beam at the planet. They proceed to laugh as the planet explodes.

Goku has been able to survive in space since OG Dragon Ball. He went to the moon using his power poll and had no problem being in a vacuum.

Vegeta and Nappa also share a scene where they are seemingly in space, yet right next to a planet. They are both standing outside their pods, then obliterate the planet and leave. Similar events occur with Bardock attacking Frieza near planet Vegeta and Goku fighting Beerus near Earth.
While I am not 100% sure if the creators meant to do this (having the above mentioned characters near the planets) they actually make it scientifically accurate. The same can even be said when Pan is flying in "space" with Hercule and co. during a Dragon Ball Super episode.
They are always in the upper atmosphere of the planet that they are near. While the air is much colder, and thinner then ground level conditions, it would still be breathable. For sayians since they are a hell of a lot more durable then the average human, they can easily survive in the upper atmosphere.

Beerus is a deity and he can't breathe in space. He needs his attendant to create a barrier around him. So, this is wrong.

Goku became a god with his godly form, he also absorbed the godly ki so Goku is technically a god now so he should be able to survive space, plus the Null Realm is basically space so yeah, Goku would be fine in space.

Please include relevant sources/references.

The null realm, the void outside the multiverse where the tournament of power happened.

Well, not really. It is clearly mentioned in Dragon Ball Super Ch 49 by Vegeta that saiyans can not survive in space.
