When did Naruto learn how to generate a Rasengan unassisted?
Jiraiya, Minato, and Kakashi each could generate and maintain a Rasengan using only one hand. When Naruto first learned the technique, he needed shadow clones to help him.
When did Naruto learn how to generate and maintain a Rasengan without the aid of shadow clones or chakra arms?

I think you should add word like perfect or stable of complete Rasengan. He was able to generate Rasengan after training with Jiraya but took long time and was not stable and fade away.

While Naruto had invented new ways to use a Rasengan and its variants, he still used shadow clones, and later chakra arms, to create them. By the end of the Fourth Shinobi World War, Naruto had become skilled enough to use the technique unassisted, with his regular Rasengan expanding to the size of a Big Ball Rasengan. so the answer is at the end of the Fourth Shinobi World War.

The first time Naruto used Rasengan without clones or chakra hands is in Naruto episode 134 at around 8:20 (YouTube video). He first used Rasengan with only one hand although he is assisted by Six-Tails chakra.

Arguably, this is still assisted by Kurama, as even after the timeskip, he still uses clones, even into his fight with Pein. it's not until Kyubbi Chakra cloak that he could do it with one had (or chakra hand) which was shown in his fight with Obito i believe, but its Sage of Six paths naruto that could do Rasen shuriken with one hand (though he may have had help from the tailed beasts) its almost arguable he never learned how to do so.

When Naruto and Sasuke were fighting in episode 134, Sasuke let his curse mark's power activate. He knew that the power would soon eat away his body, so he planned to finish off Naruto with a Chidori. However, when the Nine-Tails' cloak took over Naruto's body, he didn't need a clone to make a Rasengan. So, to counter Sasuke's Chidori, Naruto made a Rasengan with a single hand for the first time. Later on, Naruto never really noticed how amazing that was, or how he still had to use shadow clones for a while.

In the Fourth Shinobi Great War, after Sasuke and Naruto receive half the Sage of Six Paths Chakra, Naruto has the ability to maintain a perfect Sage Mode, and directly after that, he made a Lava Style: Rasenshuriken with one hand using Four-Tails Chakra and cut Madara in half with it. So he used the sage art Lava Style: Rasenshuriken first with one hand. So it is evident he could make the Rasengan with one hand after gaining the Six Paths power.

I believe it was after Naruto got half of the Sage of Six Path Chakra, mainly because in part one (ep. 135), he had the cloak of the Nine-Tails to help him, so he wasn't conscious of it. I think he was conscious of it when he fought Sasuke because he did multiple shadow clones with Rasengan. Also because of the half he received, he could naturally learn Chakra control (thus how to use Rasengan with one hand).
Also, chapter 642, sage mode.

In Naruto Shippuden the Movie: The Will of Fire, all of Naruto's clones are able to create the Rasengan independently (using two hands, granted, but independently).

It was in Naruto Shippuden when he was caught in an illusion and almost pummeled Kiba.

He did it in episode 100 when he had the vision of Sasuke and Orochimaru and ran at him with the Rasengan.

Why do some works [anime, manga, novels] have a trailing dot?
Pure curiosity.
Why do some series carry a dot [.] at the end of their titles?
Is there a meaning to it or is it convention?
Ex: Ore, Twintail ni Narimasu., Kobato.

Pretty sure it's just a period / full-stop. "Ore, Twintail ni Narimasu" is a full sentence in Japanese, so hey, why not toss a period on the end of that.

So its more like making sense of the title than just a simple styling or convention?

The second season of Oreimo (Ore no Imouto ga Konnani Kawaii Wake ga Nai.) has it, and the first one doesn't. It's actually how they are differentiated in the title. There's no 2 or Season 2 or anything of the sort.

Correct, I remember that about the series. There never was a season season of the novel (no need for that, just make another volume) - but when it came to the anime something was needed to tell them apart. Any idea why studios are choosing to go this route instead of just adding a '2' like series before.
It could simply be a newer thing though, I have noticed this practice more with novels, but it looks like it is spreading.
Sort of like the really long title syndrome. (LOL)

I think it's likely a combination of both senshin and JNat's answers - given how many light novel titles are now full sentences, it makes a certain perverse sense to make them grammatically correct by putting a period at the end; at the same time, there's also a trend to identify sequels with punctuation marks (e.g. Working'!!) which is in itself an extension of the naming convention of adding a short word rather than numbering seasons (going back to, at the very least, Slayers Next and Try).

I think it's because the title is a sentence.

The punctuation symbol  。 is called a 句点 (kuten). Although it often functions like the English period (a.k.a. full stop), it is not identical, and is used as the punctuation mark for a question sentence far more often than the ? symbol is (the question mark is called 疑問符 [gimonfu] or はてな [hatena]. Historically, Japanese did not have the question mark, so although it exists in Japan now, it is not used in Japanese academic writing). In horizontal writing, the kuten is placed in the same position as a period would be in English: at the bottom right of the preceding character. In vertical writing, it is placed immediately below and to the right of the preceding character.
Wikipedia explains that

Starting in the 1980s, advertising copy writers began incorporating full stops in titles and other advertising. In the 1990s, the group Morning Musume (モーニング娘。) began using a full stop in its name, starting a fad for this usage.

Other cases include

バクマン。 (Bakuman) manga by  Ooba Tsugumi and Obata Takeshi
いいひと。 (Ii Hito) manga by Takahashi Shin
野ブタ。をプロデュース (Nobuta wo Produce) live-action TV drama

As you can see, "Bakuman" is not a full sentence by itself, and "Nobuta. Wo Produce" intentionally slices a single phrase into two fragments by the placement of the kuten (Nobuta is the nickname of a main character that the protagonist decides to "produce," meaning to make-over Pygmalion-style.  Grammatically, you cannot make "Wo Produce" into its own sentence), so these are both examples of a kuten that should not be interpreted as a period for ending a sentence. The kuten can be utilized as a sentence ender, but it is often used for style without any grammatical meaning. Similarly, some series titles make use of other Japanese typographic symbols for style such as　, ＊, ☆, ♪, and ♯ (for example, うたの☆プリンスさまっ♪ [Uta no Prince-sama] and おジャ魔女どれみ♯ [Oja Majo DoReMi Sharp] and the choice of a star to be read as the letter A in ST☆RISH, an idol group in the former).

What is the name of the song played during the scene where Asuna is buffing the party underwater in SAO Extra Edition?
The song I'm referring to is often called the "Underwater quest BGM", as it is first played when Asuna is buffing the party in the Extra Edition. The next time it is played is in SAO II episode 2 near the ending.
Which album was the soundtrack placed in? Last time I checked, it wasn't in Volume 1 nor 2 of SAO II's OST.

Please take a look at the revision to see whether I changed the meaning of your post. Not sure what you mean by "Season's OST"

@nhahtdh You are fine there.

I do not think the song has been listed as of this moment it was not include in the 2nd ost volume or any of the extra music offered on discs.

That song's real name is 'Moon and shadow' and is the 19th song of disc 4 of 'Sword Art Online Music Collection' (ソードアート・オンライン ミュージックコレクション)
which was released on 2016.01.27 (Catalog Number SVWC-70116~9).

I'm afraid you're out of luck for now. The musical piece has not been released on any official soundtrack of Sword Art Online. It may be included in a package to be released in the future (but I haven't found any statements from the producers to this effect).

What does this symbol represent on this payphone?
In the sixth episode of the second season of Darker than Black, Hei hung up a payphone.

On this payphone there is some symbol. They’re supposedly in Russia; however, the Russian currency symbol is ₽. What does this symbol mean? I doubt they would make up a currency since they also reference the CIA and MI6.

Have you actually seen that symbol get used in Russia? In my recollection, I only remember руб being used …

Not only is that the symbol for Japanese yen, the phone itself is also something utterly Japanese, a pink public phone:

They're very iconic (somewhat ubiquitous decades ago when you'd see them in shops or restaurants) but also very outdated (They only take 10 yen coins which is not much at all). If there are any still being operated then as something between a curiosity and a "living fossil".
So basically, if that scene is supposed to play in Russia, it's either some sort of joke or the animators were very sloppy, maybe reusing a generic "using a public phone" sequence.

That's just the Japanese word "yen", written as a word 円 en rather than with the currency symbol ¥.

So we can just chuck it up to the animators preference rather than some in universe reason why Yen is being used in Russia?

That's the kanji 円, pronounced "hen" or "yen", which means both "circle" and, as you might have guessed from the pronunciation, the japanese currency.
The ¥ symbol is the international symbol of the currency used for trade deals and in tourist destinations inside Japan, while 円 is the more common and japanese way to refer to local money.

So we can just chuck it up to the animators preference rather than some in universe reason why Yen is being used in Russia?

Pretty much. This could be a mistake, it could've been done on purpose, or it could just be a case of whoever was assigned to that specific series of frames not caring enough.

The pronunciation you're referring to is neither "hen" nor "yen", but "en", like in "and" but without the terminal "d". Any other pronunciation is totally different.

Is there filler manga?
When watching anime I often come across filler episodes or arcs. They are often episodes that are not described in the manga.
I haven't read much manga, so I was wondering: Does manga also have filler volumes?

Depending on your definition of filler, I would say yes, there are indeed filler arcs in manga.
I say this for a few reasons.

The other answer on here as I write this assumes that the manga is always the original content, which is untrue. While that's the most common way to do things (adapt manga into anime) there are certainly cases of adapting anime into manga form (for example, Madoka Magica).
Consider this TV Tropes page. It offers a few definitions of filler. One is something that "isn't in the source material." However it could also be considered something "unrelated to the main plot," which doesn't necessarily mean that filler arcs are exclusive a specific adaptation.

For example, consider the Excalibur arcs in the Soul Eater manga, which also appear (almost verbatim in some cases) in the anime. They have no practical effect on the overall story - they exist simply for comedic effect. If you skipped those chapters, the overall story would not really lose anything.
Therefore, yes, manga can have filler, because filler can be defined as anything which does not have a direct effect on the main story.

My theory of filler is when it is used in anime to fill up the anime with more epsiodes to create a gap between the manga storyline and the anime storyline as in so they won't catch up to it.

That's certainly one definition, but as per the page I cited, it's not the only definition. In other words there's several types

It is certainly wrong what you are saying, "filler" is a term of "filling the gap" for anime so it won't catch the manga, you just invented a new term of "filler" that fans made, and not for that purpose.

The answer is no,
Basically what a filler episode is is a episode that does not involve any content from the original manga, these episodes are called "non-canon" or like you described it as "filler episodes".
The manga is always 100% non-filler, but the anime adaption can contain these filler episodes.

I wouldn't say that's always true, there are often chapters that don't advance the story in any meaningful way. After all, there are often scenes in manga that are published with the corresponding anime as OVA's, and they generally don't develop the plot.

How could Amagiri have eggs on him after he teleported with Brita?
In episode 24 we see Brita and Amagiri teleport inside PANDORA and steal some clothes from a group of guards.
we know that Amagiri's remuneration/obeisance is to eat boiled eggs. We also know that Brita's ability is:

Teleportation: Her ability is to teleport herself and anyone she is in
  contact with; however, any clothing, tools, or weapons are left
  behind.

Source: Darker Than Black Wikia
How would it be possible for Amagiri to have eggs on them after they teleported using Brita's ability?

My guess is maybe because clothing, tools and weapons would be "more processed" in how they are made than boiled eggs (eg. Weapons = Natural Ore that needs to be refined to produce metal and metal needs to be worked into shape VS Boiled Eggs = Eggs laid from a chicken cooked in hot water which can also be produced naturally) Brita's Power ignores anything humanity has tampered with. kinda fits with the theme that humanity is being replaced by Dolls

That is one of the eggs he and Amber made together earlier in the episode.  He pulled it out of his pocket after she rewound time to save his life.
So Amber put the egg in his pocket.  That's why he stopped and stared at it.

Are there differences between Web Novel, Light Novel and Manga of Mushoku Tensei?
I'm currently reading manga and I was thinking to switch to LN or WN so I'm wonder to what I should read WN or LN.
I'm current in chapter 15 in manga.

As far as I know, the manga follows the same path as the web novel with much skipped content. I don't know about the light novel but I read somewhere that there are some differences. And according to Wikipedia (link), there exists a whole volume between WN volumes 6 & 7, that covers Rudeus' adventures following Eris' departure.

Mushoku Tensei manga is an utter disgrace to the novel.
I'd recommend reading the translated web novel.
There's not much difference between the web and light novel. But the light novel's only been published till volume 8 right now.

Why did the Rokka no Yuusha opening song change after episode 4?
After episode 4, the opening song for Rokka no Yuusha changed from "Cry for the Truth" by Michi to "Black Swallowtail" by Uroboros and Tom H@ck.
Why did Passione (the studio) change the song? It seems weird since the visuals in the intro are the same and it's still the first season of this anime.
Update: Episode 12 seems to use the first opening again.

Have any new characters entered the intro perhaps? Maybe they wanted to hide them until the plot introduced them

@ToshinouKyouko I don't think so, the visuals are almost the same as with the first opening.

"LOOK AT ALL THIS MONEY WE HAVE!!"
"Should we make more episodes?"
"Don't be ridiculous, 12 episodes is the anime standard!"
"So what should we do with the extra budget money?"
"What episode are we at again?"
"4"
"Okay, for the next one, CHANGE THE OPENING THEME!!"
"What about the visuals"
"Do we have enough money to change those too?"
"No..."
"Well those can stay the same."
And that is why something like that happens, there's no meaning behind it, they do it because they can.
To be honest, there might have been a disagreement from the start about the opening theme and they just decided halfway to switch, or maybe the majority didn't like the first theme so they decided to try to do what was best for the anime.  All this to say, it has nothing to do with the anime itself, I watched it too, and nothing really changed from episode 4 to 5.

Are you sure it was because they had extra budget money though? It also seems very possible they had some bond to the other artist and wanted to promote that song instead.

My point being it has nothing to do with the anime, and I also did say that they might have had a disagreement from the start about the opening theme. ie : they might have liked more than one band or as you said they had some bond to another artist.  The stuff at the beginning was just to show that it had nothing to do plot wise or had anything to do with the anime as a whole, the songs changing was unrelated and more or less, just because they could.

What happens if citizens take off the PM?
In the first episode we learn that the PM (Peace Makers) are used to check if a citizen is using blacklisted words.
Couldn't they just take take the device off when they aren't in public instead of having to use some cellphone to disrupt the PM's surveillance?

It's affixed to their throats, it would probably just go off, like when a lewd word is used, and alert the Decency Squad.

What happened to Sanji in Zou?
The current situation of Sanji has not been made clear so far in the manga. The following is a summary of the pointers.

Sanji is the only person in the SH crew who is wanted Alive and not Alive/Dead.
His bounty has increased only by a 100 million Berries (to 177m berries ) which suggested that he was involved in any earth shaking event at Zou.
Nami is seen crying when she says to Luffy, "I'm sorry about Sanji" and there is nothing added on to it.
Brook says, "I'm so sorry about what happened to Sanji san. I can't even face you right now".
Strangely Luffy and crew are not at all worried about Sanji and don't feel obliged to go to his aid.
In the last seen image of Sanji he is seen tacking cannon balls from some ship and before that he defeats the Kaido crew pirate Sheepshed.

Considering the above, I like to know some plausible theories on the current condition of Sanji.

I assume Sanji was mad to Usopp's new bounty, left a letter to the other SHs that he is sneaking onto Jack's ship which attacking the marines to ruin Jack's plan and get a higher bounty of it.

Sanji was taken from Zou by Capone Bege as per Big Mum's instructions, and invited to his own wedding, a diplomatic marriage between Sanji, the third son of the Vinsmoke family and Purin, the 35th daughter of the Charlotte (Big Mum) family.

Note: After reading the A&M rules and a few related questions, it would appear that I am not violating the "back your sources" rule as this is a speculation question, which appears to be allowed (see Is a question that asks about a future event on-topic?). Either way, my answer is the following:
Knowing that One Piece is a Shōnen Manga (Main characters not dying easily is one of the trends) and that Sanji is fairly popular, here's what I can come up with:
My best candidate:

Sanji broke his leg(s) with one too many Diable Jambe

Will probably have a Miraculous Recovery later on

Other possibilities:

Sirens/Mermaids saved him when the ship fell in pieces, current location unknown.
Temporarily Dead

In the unlikely case that Sanji is dead, here is what could have happened:

A Kraken (or other Mysterious Being From The Sea) finished him
One of the Kaido crewmen escaped and wanted revenge
Ate a devil fruit and drowned.
(Comical) Ate a devil fruit, got rescued by a mermaid, but died of nosebleed.

To answer point #5, Luffy believes in Sanji. Following the Shōnen archetype, when the main character says it'll be okay, it'll be okay. If sanji broke a leg, he'd probably crack a joke about having rubber bones, or something.

stating that you have to violate a rule doesn't make the violation acceptable

I did more research and corrected my statement.

Why wasn't the Susanoo used?
During their fight with Kaguya, Obito, or even Sasuke didn't use their Susanoo which could have protected them from Kaguyas "Bone Ash" jutsu.
Same is the case when Sasuke fought Madara (Tobirama was lying on the ground paralysed and Sasuke jumped from above to attack Madara). Sasuke could have used his Susanoo, but he didn't.
Was this just a loophole on the writer's part? Or is there a reason behind it?

I'm pretty sure Sasuke uses it...

Nope,he doesn't.Madara stabs and almost kills him.

Kaguya can absorb all forms of ninjutsu, which rendered Susano'o useless. Sasuke only uses techniques like that on people who dont absorb jutsu, like Naruto. Plus, there would be no need to use Susano'o on Madara's Limbo Clone because physical attacks do not work on it. When he had chances to use Susano'o against Madara's Limbo, he didn't understand how the jutsu worked and might have felt there would be no need for its use. They have recently been putting Sasuke in situations where he doesn't need to use his stronger jutsu, like Kagatsuchi or Susano'o, which is why his fights have started taking way longer than they should be.
As for why Obito can't use it, there is literally only one manga panel that completely sums it up.

Obito had already given Kakashi his left eye by the time he awakened Mangekyou Sharingan, thus couldn't use Susano'o. Obito is later seen to get back both of his Sharingan, but since he awakened it before he had both, I guess the eyes could no longer be seen as a "vessel" for Susano'o to be used.

While battling Kaguya, the Susanoo was not a good option because of her abilities. In Episode 459 of Naruto Shippuden, Sasuke was actually using his Susanoo during the beginning of the fight. However, Sasuke stopped after he realized that Kaguya's Rinne-Sharingan ability could absorb all forms of Jutsu, including his Susanoo.
Just like Green mentioned, the Susanoo is a massive humanoid projection of its user's Chakra and so the entire Humanoid avatar can be absorbed by someone who posseses the Rinne-Sharingan, and thats actually what happened when Sasuke tried to attack Kaguya with his Susanoo, she simply absorbed the attack along with his entire Susanoo.
In the case of when Sasuke came after Madara (Episode 393), He was trying to catch Madara off guard while Tobirama kept him preoccupied, and so a Susanoo would have been a bad choice in that scanrio because of how big it is and since its a massive avatar of chakra, anyone could easily sense it.

No what I mean is why didn't sasuke use the Sussano when Madara had caught him in his limbo?

Is Ashura the actual creator of the "Rasengan"?
So as you can see in the fillers, that when Ashura is helping out the other villagers, he is using a jutsu just like the Rasengan.

Is this the Rasengan we know and love, or is this a different jutsu for say a wind release?
If it is indeed the Rasengan, then does this mean that Ashura is the original creator, and not Minato Namikaze?
If the second one is true, this could mean that Minato has some relations with the Ōtsutsuki?

I meant Minato BTW but both sayings are correct.

You can always hit the edit link below your post to fix things rather than comment.  It will make it much easier to read (and then people don't need to filter through the comments to figure out what you meant.)

@Becuzz I Didn't Know, im new to this website but thank you for telling me this

It depends on what you consider canon. Almost all of the Ashura and Indra and even Kaguya backstory stuff was anime only filler. The manga has almost none of that. Thus, in the manga, there was no mention of Ashura ever using Rasengan, or pretty much any specific jutsu for that matter. Indra's eyes barely resembled a sharingan, and Hagoromo was never known to not have the Rinnegan. So in that regard, Ashura isn't the creator, its just anime only filler. They likely chose things like the Rasengan and Sasuke's Mangekyou and put them on the two brothers to try and make it all seem more like destiny or something, symbolism that things are repeating themselves. Its pretty low quality story and a plot hole because Madara doesn't have the same pattern even though he was also an Indra trans-migrant. The story wasn't about destiny, but instead about how Naruto used the power he was given to change things, when the world finally was ready for it.
If you consider anime filler canon, then indeed he is the original creator, but like another answer here points out, he didn't pass it on. Minato most definitely developed the Rasengan on his own. In that regard, they both are the creators, Minato just rediscovered it.

Nobody even knew who Indra and Ashura were before Hagoromo told his story.Indra are Ashura are ancient history.Not even Hashirama/Madara knew about them.
Yes,Ashura was the creator of Rasengan.In fact,he had already created an advanced version of it-multiple Rasengans.Howeved his jutsu was probably not passed down to the next generation,it was forgotten.
Minato re-discovered the Rasengan and essentially,became it's present creator.Rasengan is actually a ball of chakra-you could add a Wind Release to it and make it Wind Style and stronger as well.The reason why it's so powerful is because it's pure chakra,unlike other jutsus where you have to convert your chakra to the desired "style",like the Fire ball jutsu.
Clearly,Minato has no relations with the Otsutsuki clan.

...Ashura created the Rasengan it was never passed down because nobody had the skill at the time to recreate it since the concept of chakra was new to the world Indra had his sharigan during his battle with Ashura...I’m pretty sure that story was Canon it explained things in the main story line unlike side missions used for filler

Can you provide citations or any additional details?

You're already answered it yourself. It's a filler.
Aside from that, I don't think that counted as Rasengan, since it wasn't really a perfect compressed sphere, but a round unstable mass of wind release chakra. So you could say in this filler, Asura used a proto/pseudo/imperfect Wind Release: Rasengan. Also, the Rasengan was explicitly stated to be based off of the Tailed Beast Ball, which automatically makes it structurally and functionally different from whatever Wind Release technique Asura was using in this episode. It looks like a Rasengan, but it's not. Just like Chidori and Raikiri are similar to whatever technique the 3rd Raikage used.
There is no relation between Minato and the Ōtsutsuki Clan.

Just like GK A said ashra's chakra wind release is similar to the rasengan just like chidori and raikiri are similar to the 3rd raikage thrust of hell lighting style jutsu plus it possible that ashra created the rasengan but due to the fact that he didn't teach anyone how to do it and no one border to try copy it may be because it was he's jutsu like his thing.
so eventually as time pass by his jutsu was forgotten and minato namikaze rediscover it due to inspiration of a tail beast's most powerful jutsu known as the tail beast ball but again it's highly possible to say that ashra didn't create the rasengan but the birth state or form of it just like how the rasengan is the birth state or form of the rasen-shuriken and again ashra's rasengan like jutsu was a projectile type jutsu while minato rasengan is a contact type jutsu.
so technically they both got there inspiration from the tail beast ball but had different law for human possession like how ashra's rasengan like jutsu copied the projectile feature of the tail beast ball but was a chakra ball like bubble with five rasengan balls rotating in it and how minato's rasengan copied the oneness feature of the tail beast ball but was a contact type jutsu not a projectile like the tail beast ball so clearly due to my idea on who created the rasengan one can say that ashra did not create the rasengan, minato did just like how u can say that minato did not create the rasen-shuriken, naruto did.
clearly one can call ashra's rasengan like jutsu the rasen-hado or ashra's rasengan like boruto vanishing rasengan a rasengan but a projectile type jutsu just like his ashra's kurama mode!

Who is stronger Jiren or Broly?
Some people say Jiren is stronger than Broly, while some people say Broly is stronger than Jiren. Usually, in Dragon Ball, the next enemy is stronger. However, this pattern was changed in Dragon Ball Super as Beerus is stronger than most of the antagonists that came after. So who is stronger of the two?

 Dragon ball generally follows a pattern where the antagonist tends to be > than or around the level of the protagonist. If you go back to Dragon Ball Z, Super Buu is stronger than Kid Buu and Buuhan and Butenks are way stronger than Super Buu. However, Kid Buu was the final antagonist. The antagonist's power is generally adjusted to be comparable to the protagonist they are fighting. Since Ultimate Gohan is stronger than Super Saiyan 3 Goku, they had him fight Super Buu. The same goes for Vegito, who fought the strongest iteration of Buu. Just like you said, despite Beerus being stronger than the rest of the antagonists after, they did use a greater amount of power against Goku and co.However, after watching the movie, I personally believe there is sufficient reason to believe that Jiren might be stronger( At least the version of him where he releases his dormant power). There are several reasons why I believe this to be true:The Tournament of Power emphasizes the fact that Goku surpasses the Gods and manages to overcome Jiren. This was constantly emphasized during the course of the tournament while he was Master UI. Jiren was able to go toe to toe with this iteration of Goku and also come out on top in terms of raw power. When the trailers and initial summary of the movie first came out, it was stated that Goku was almost reaching the level of a God and Vegeta was catching up(This makes sense because it was established at the end of DBS that Goku does not have access to Ultra Instinct anymore).Broly as a Super Saiyan was no doubt stronger than Super Saiyan Blue Goku and Vegeta. However, there isn't a long enough fight to determine the exact difference. Goku and Vegeta would have definitely grown stronger compared to the T.O.P. However, they were using forms 20 times stronger against Jiren who was nowhere near full power while fighting these two. Also, Golden Frieza managed to last against an agitated Broly who was looking to kill. He barely lasted for a second against Jiren who took him out with a glare and a single punchIn the tournament of power, it was more or less implied that the only way to defeat Jiren was for Goku to master Ultra Instinct. If Goku and Vegeta could've defeated Jiren with fusion, it would break the entire plot and the entire struggle against Jiren wouldn't make sense. This is because Vegeta had absolutely no problem working with Goku and doing everything to win. It was stated that Fusion was allowed and they both saw a potara fused a character a while back. Not even Whis or anyone stated Goku and Vegeta would be able to win this fight fused. So I do believe Jiren at the time was stronger than Vegito, hence Gogeta(Definitely when he releases his dormant power). SSJ Broly had a disadvantage against SSJ Gogeta. LSSJ Broly could barely hold his own against SSJB Gogeta.Finally, at the end of the movie, Goku compares Broly's power to that of Beerus. However, Goku and Vegeta mentioned that Jiren was the strongest they ever faced when they fought him, implying Jiren was > Beerus.(Goku says a suppressed Jiren's punch was the strongest he's ever faced, Vegeta says he hasn't felt a level of energy like this before). The V-Jump magazine had an article where Beerus comments that Goku has surpassed him after achieving UI, which you can see here. In the Battle of Gods arc, SSJG Goku was said to be stronger than Vegito. If you compare the difference between SSJ3 and SSJG, the power is significant indeed. However, the difference in power is a lot less if you were to compare SSJB + Kaioken * 20 To UI Omen, the difference in power is a lot more significant, and Mastered Ultra Instinct is substantially stronger than the two. Since the potara multiplier is fixed, I believe MUI Goku would still be strongerIn conclusion, the next arc of the manga states that Goku was still attempting to master UI as he tells Vegeta that he hasn't been able to tap into the transformation even once after the tournament of power. So if the series were to resume, Goku might most likely tap into this form against a stronger Antagonist than even Jiren and Broly. There is promotional material about Broly's strength claiming how he is one of the strongest and they say his level of destruction might be greater than that of a God of Destruction. The source for this can be seen here. However, there is no legitimate valid source indicating Broly to be stronger than Jiren. DBS did something new in the series by having Goku achieve two transformations in 1 arc and at the end of the arc, not be able to tap into it anymore. I think this on its own is sufficient evidence as to how Over Powered this iteration of Goku is and why the plot decided to take this transformation away before bringing characters even stronger. Plus, Whis's training is mainly focused on making them achieve the form. If Goku did achieve it, he would technically have completed Whis's training which is necessarily not the case based on the beginning of the movie.

There is no conclusive evidence in my opinion but, I think it's Jiren because of this mainly, the Broly movie apparently takes place shortly after the tournament of power, and Freezer was able to resist being beaten by Broly for 1 hour when in the tournament of power Freezer was seriously damaged by Toppo, who is at least 2 levels behind Jiren full power (Toppo is weaker than Jiren not using full power).
Aside from that, Goku thinks Broly "might be stronger than Beerus" which in my opinion means he's close to Beerus's power (since Goku isn't sure) when Jiren is said to be stronger than gods of destructions when Jiren was almost a match for Goku mastered ultra instinct (a state to which all the gods of destructions almost vowed to, they stand up when Goku transformed as a sign of respect or admiration, like admitting it was a state superior to them, Beerus had to ask Wiss about Goku's power because it was beyond his comprehension, Beerus sweated to Goku Ultra Instinct Omen which was almost a match for Jiren not in full power and the other gods of destructions were surprised, etc.)
Eventually, we could get an answer in some of the Dragon Ball Heroes versions which wouldn't be an answer for the canonical universe, but an answer for one of the Dragon Ball versions.

Why is Tajū Kage Bushin no Jutsu a secret?
In the first episode/chapter of Naruto, Naruto steals the scroll containing secret jutsus and, from it, learns Tajū Kage Bushin no Jutsu, the multiple version of the corporeal alternative to Bushin no Jutsu (which they learn in school). While Kage Bushin no Jutsu seems to take way more chakra and is a lot harder on the user than Bushin no Jutsu, it doesn't seem particularly egregious. Additionally, a decent number of characters seem to use it, if the Wikia article is to be believed. While most characters who use Kage Bushin no Jutsu don't make multiple clones, it doesn't seem like a massive leap from one to the other. So why is it kept secret and sealed away in the Scroll of Seals when other jutsus that are incredibly hard on a person or even potentially fatal (like opening the Eight Gates) aren't?

i was about to suggest that it's forbidden to Naruto out of fear that the 9-tails's seal could weaken because of it, but then that wouldn't explain why it's restricted to all other ninja which would be the point of having it sealed away and guarded effectively by the Hokage

While https://anime.stackexchange.com/q/2145/93 answers broadly why it's forbidden, I'm specifically wondering why it BUT NOT comparably or more harsh jutsus aren't.

It’s a forbidden jutsu because of the amount of chakra it requires. Along with that with certain users of the jutsu it could increase their numbers from 1 to 1000 creating a small army.

The eight gate that you gave in the example is a forbidden jutsu and not just everyone can learn it (i.e. sealed). The only known users (manga canon) of this jutsu are Might Guy and Rock Lee, both are Taijutsu masters with the first was even commended as the greatest Taijutsu user ever by none other than Uchiha Madara. Even Lee are not able to open all 8 gates, only Might Guy can. Other than ability, it was also suggested that Might Guy has yet to teach Lee how to open all 8 gates. Lee was limited to the 6th gate. This means that the jutsu is somewhat "sealed" by Guy.
Another forbidden jutsu that was not sealed is the Rasen Shuriken. But that is because Naruto created it himself.
The rest of the kinjutsu are used only by powerful ninjas, sometimes by stealing the scroll (like Deidara did), or the kinjutsu requires Kekkei Genkai (like Izanami and Izanagi).
Thus the conclusion is that other kinjutsu are sealed, just like Kage Bunshin no Jutsu was.

The shadow clone jutsu was invented by Tobirama senju. The reason it is a forbidden jutsu is because it drains the user's chakra. When kakashi was fighting PAIN he lost a decent amount of chakra to the clone.
Why is the multi shadow clone jutsu a forbidden jutsu

I think it works like, the shadow clone jutsu isn't forbidden (just 1 clone) but the multi shadow clone jutsu is forbidden because anything more that 1 clone drains too much chakra ( anything over 2 clone )

What's the difference between Endeavor and Dabi's quirks?
Endeavor and Dabi seem to have very similar quirks, with the exception that the flames Dabi generate are blue. Is there any other difference? Is one quirk stronger than the other in some way?

I guess, more or less all fire quirks are similar.

Both quirks essentially do the same thing, but blue flames (used by Dabi) are hotter and more fuel efficient than red flames (used by Endeavor) though Endeavor uses blue flame as special move while all of Dabi flames are blue.
Because blue flames burn oxygen more efficiently, Dabi can create big attacks with less effort than Endeavor.
In my opinion Dabi quirk is more stronger than Endeavor quirk.

Good answer but I recommend you include sources pertaining to the science behind flames to further improve your answer.

For now it's just speculation (manga reader) but there is a high possibility that Dabi is the son of Endeavor. As manga and anime stated Endeavor tried to create best quirk even one to exceed All Might. Fan base speculated that Dabi is one of his failed attempts.
Further evidences:

We know that Shoto Todoroki has two older brothers. We see one in the latest chapters of manga. One is still unknown.
Left eye colour of Shoto Todoroki and Dabi's eye colour is same (Turquoise). Also, Endeavor's eye colour is Turquoise too.

As for the question itself they're both fire based Quirks, but strength wise, it's same. Colour difference is because of incomplete combustion (blue).

Was Universe 18 restored by the Super Dragon Balls?
Dragon Ball Super ended with Android 17 wishing for all universes to be restored.
Does this mean Universe 18 has also been restored as it was erased by the Omni-King in the past?

I removed the last question regarding "new DB plot" because it's primarily opinion-based. Also, the 1st question might be answered objectively, but I'm not sure about the 2nd one. However, I'll leave it to users who have more experience in the DB series.

I'm assuming this question is based on a recent fan video from a prominent Dragon Ball Youtuber. That was primarily opinion based and has no association with the Dragon Ball Franchise. The first part of your question, has been answered by me here. I suggest this question be closed.

Does Hiro Mashima (Fairy Tail) have something in common with Eiichiro Oda (One Piece)?
Hiro Mashima, the author of Fairy Tail, has a really similar drawing style to Eiichiro Oda, One Piece mangaka.
We know that some well known mangakas had previously worked as assistants to others (like Hiroyuki Takei and Eiichiro Oda himself, both worked with Nobuhiro Watsuki), so I was wondering if Hiro Mashima has something in common with Eiichiro Oda, since they had very similar styles at the beginning.

When read the first Fairy Tail chapters, my first thought was: Another "One Piece"... glad it turned out not to be quite so, but it does have a very similar style.

I have read that Oda and Mashima are good friends. However, not only has Mashima never been Oda's assistant, but he has never been an assistant to any mangaka. The resemblance of their artwork is due to something they share in common: Toriyama worship and obsession with Dragon Ball. More details on this blog post.

What is the symbol on Kakashi's ninja dogs' backs?
Every one of Kakashi's ninja dogs has a symbol on its back that looks like a face:

What is this symbol and what is its meaning?

It's a pretty interesting explanation... In this wiki for Ninken (Ninja dogs):

They all have a face-shaped design on their backs called Henohenomoheji (へのへのもへじ) — which is the sound made when all the characters in the face are put together. Appropriately enough, children use this design as the face for their scarecrows, which is "kakashi" in Japanese.

Basically, if you consider the picture you included:

The eyebrows are the Hiragana へ (he);
The eyes are the Hiragana の (no);
The nose is the Hiragana も (mo);
The mouth is another へ (he);
The head shape (kind of distorted) is the Hiragana じ (ji).

So, へのへのもへじ (henohenomoheji). The first "heno" is repeated because you have a pair of eyes and eyebrows.

I wonder if they took this into account when naming Kakashi. +1 answer!

Or rather, if they took Kakashi's name into account when designing his summons.

What is the difference between a regular wall and the wall Kakashi summoned?
In chapter 420, Kakashi summoned the wall of dogs (Doton: Doryūheki).

It looks just like an ordinary earth element wall, except that it has bulldog sculptures on it.
It's already known that Kakashi was familiar with the earth element very well.
So why did he summon this wall?

Let's see what was Kakashi trying to do. First of all, he summoned the wall behind Pain. So his intention was not to make a barrier to protect himself, but rather to limit Pain's movement, probably to make it harder for him to evade Kakashi's attacks. Right after that he tries to hit Pain with Raikiri, but because of Rinnegan he misses and hits the wall instead. Note that Pain is already pushed to the wall, so he can not evade backwards.
So basically he has just two ways to move to left: forward, from where Kakashi is attacking, or upward, trying to jump over the wall. Considering this, I would assume that the dog heads are there to prevent the enemy from doing so, and possible catch and hold him at the wall if he is reckless enough.
Note that it is not the only technique which combines Earth element and Kakashi's dogs. He also uses Kuchiyose: Doton: Tsuiga no Jutsu (literally "Summoning: Earth Release: Tracking Fang") in his battle against Zabuza. In this technique, tha dogs travel underground, track their target and then assault it with their fangs to hold it still and let Kakashi hit it with Raikiri.
So yes, I think the wall had roughly the same purpose.

If what you say is true, what did he try to accomplish when he summoned it against seven swordsmen of the mist (At the early episodes of the fourth war).

@Hashirama, where exactly was it? My answer is rather an assumption based on Kakashi's actions; the wall might as well look like this because it is just cool ;)

@Hashirama, by the way, the wall he uses in chapter 608 looks different from the one in chapter 420 (there is no dog with it's mouth open)

Why aren't the Nomus' brains attacked?
In My Hero Academia, the Nomu are incredibly strong creatures that possess multiple quirks. Even a single one of them proves to be a big threat. Nomu or not, the brain of any creature is very weak and one could die if it doesn't have any kind of protection (usually skull). The Nomu seem to have brains without any kind of protection. They are clearly exposed and visible to everyone around. Considering the fact that the Nomu are strong creatures and the law doesn't restrict to kill them (since Endeavor killed many of them at the Hosu incident and also the high-end one), why don't pro heroes attack the Nomus' brains? (I know it looks gross and all the stuff, but that doesn't change the fact).

Maybe they did try to attack but the Nomus defended themselves.

Endeavor incinerates the head of one.  I think it mostly boils down to some combination of three things (1) it's a show for teenagers or thereabouts, you can't show too much brutality; (2) most of the heroes make an effort to maintain a good public image that's palatable to adults and children alike (for some that seems to be their only goal), and bloody, lethal attacks kind of work against that.  Endeavor is one of the few who doesn't care that much; and (3) heroes are a regulated part of the justice system, and pre-trial killings threaten justice and society's tenuous acceptance of quirks.

But that's just my speculation.  I don't know if there's anything specific we can cite from the manga or anime that would favor one or more (or any) of them.

Sujal Motagi There are heroes who specialise in accuracy like a teacher in UA. They can shoot from a distance when he Nomu is off guard and if it hits their brain they are done for, right?

First of all, not all Nomu have their so-called brains exposed. Their description hints that they are "mindless" soldiers that  need specific orders to function. Only the High-Tier ones have the capability to think for themselves. On the same note, you could wonder why they don't target the eyes of Nomu.
On one hand, giving that they all have muscle augmentation and others physical quirks, one could reason that the visible "brain" tissue is just a protective layer for the brain itself. On the other hand, it could be that the Nomu are aware of this "flaw" and one can't easily target that area, being direct attack or range attack. Also, most fights in manga/anime don't revolve around the characters targeting the weak spots of the body, meaning that even in BnHA, the Heroes don't go for the head when fighting any other villain to give them a concussion or something like that, the fights are a display of abilities and power.
And finally, my opinion is that it's just a design trait that Horikoshi - the author - liked and incorporated in the making of Nomu.

Endeavor yeeted a fire spear or something at the flying Nomu’s “brain”.However the Nomu has the regeneration quirk and the “brain” would probably regenerate.

In Chapter 621 Hashirama summoned a Buddha statue. While doing that, he has some markings on his face similar to the ones Naruto has when in Sage Mode. Does Hashirama have some sort of Sage Mode?

Yes, it is Sage Mode, since Senpou means Sage Art. The technique is Senpou Mokuton: Shinsuusenju (Sage Art Wood Release: True Several Thousand Hands).

Is Beelzebub's main focus on comedy or storyline?
I have started watching Beelzebub anime. The anime is very funny, and I feel there is a plot in it.
Does this anime have a real plot or is it just a comedy like Gintama?
By a real plot, I mean that the story is more important than the comedy (One Piece for example).
So, is it leaning towards One Piece or Gintama in terms of plot?

It's plot is given quite early, but is often overlooked. The plot it that Oga is supposed to raise Beelzebub into the new Demon King. Simple as that. This includes everything from Oga and Beelzebub growing stronger, to gaining minions and so forth. The anime and manga are quite easy going, but slowly and with no rush, it's moving further against the goal.
You may ask yourself what Oga feels about having his "son" to become a powerful and merciless Demon King, however thoughs regarding this hasn't been mentioned more then a couple of times with no further talk about it.
Personally, I prefer to read the manga due to the anime being cancelled. I've yet to get tired of the manga due to all the awesome and funny things occuring in it. I gave up on the anime once I knew it wouldn't continue.
To answer your question;
Beelzebub is a comedy with a (slim) story.

When does Kakashi first use his Mangekyou Sharingan?
In Naruto, when does Kakashi first use his Mangekyou Sharingan? Because as far as I know, he and Tobi both awaken their Mangekyou Sharingan when Kakashi saw Rin and Obito get killed, but he never uses it in the series until Shippuden.

Your question probably is, "Why didn't Kakashi use Mangekyo Sharingan earlier?", because I am pretty sure you know when he first used it.

Well.. Account has been suspended anyways ..

@Sai Just as I had suspected, this account was using a sock puppet account named "laxter". The answer below was given by the sock puppet. The accounts got merged, so it looks like that.

I don't understand the need to use a sock puppet to answer own question, especially when SE explicitly encourages answering own questions.

to gain (more) reputation! probably he thought no one would know, being unaware of admin privileges..

In a fight with Itachi and kisame when Kakashi jumped in to help kurenai and asuma he had to suffer tsukoyomi of itachis sharingan. Why he couldn't do a counterattack with his mangekou sharingan.

He needed more chakra control and his stamina is sub-par. That timeskip made everyone get better so that's most likely the reason. Plus, he is a non-Uchiha and that's why he can barely handle it. Maybe he first used his Mangekyou Sharingan during his fight with Deidara.

I'm also not sure he was even aware of it at the time. He fainted immediately after activating it.

Kakashi's first known use of the Mangekyo Sharigan was against Deidara. However, I think your question really is why did he not use it earlier. There could be a number of reasons why he did not use it or was not shown using it earlier.
Kakashi awakened the Mangekyo Sharingan when Rin was killed. He thus failed to keep his promise to Obito. Hence, this was a emotionally painful moment for him, tied to both Rin and Obito. Maybe he did not want to use it since to avoid revisiting those emotions.
As mentioned in lexter's answer, another reason is that being a non-Uchiha, he simply did not have enough stamina to use it effectively in battle. Even after timeskip, he could only use it twice in a day, and had to take rest for a week or so after he used it. Before timeskip, he was in charge of genin-level students, and he couldn't risk getting knocked out and put his students in danger.
Also, before the timeskip, he simply did not get to fight villains against whom he was forced to use it. He only fought Zabuza and Haku during the Land of Waves arc, and unnamed shinobi from Sand Village and Sound Village during the Invasion of Konoha arc. If Orochimaru were to fight him, Kakashi would probably be pushed to using it, but Orochimaru fought with the Third Hokage instead.
Losing to Uchiha Itachi easily may have compelled Kakashi to consider using it, due to the usual shounen/Naruto logic of "If I want to protect my nakama, I have to get stronger."
There could also be a couple of author issues why Kakashi couldn't be shown using it earlier. Sasuke was a protagonist at the time, and his main aim in life was to kill Itachi. Therefore, it was necessary to introduce Itachi as a superpowerful villian. Ensuring that Mangekyo Sharingan is first mentioned when Itachi is introduced would maximize the audience's perception of how strong and evil Itachi is.
The other reason is it was not in the author's plan that Kakashi had already awakened the Mangekyo Sharingan when the series started, and planned to offer an alternate explanation for how he awakened it during the timeskip period. However, as he started addressing the hanging threads while winding up the story, he decided to shoehorn it into Obito's backstory.

My friend just discovered this in the anime (first season, episode 6, at about 6:35) which I think supports the other explanations. Kakashi is about to use it when he is caught in Zabuza's water prison jutsu. You can see it in this image. This would indicate that he is ready to use it in a near death situation.

Interesting. Do you have an episode number?  I'd like to revisit that.

We revisted it to, and it is just before he is caught in the water prison, here is a link to the episode and it happens at 6:35
Link: http://kissanime.to/Anime/Naruto-Dub/Episode-008-The-Oath-Of-Pain?id=103875

Okay.  It certainly seems like he could have used or have chosen to use it, but the real question would be, why didn't he?  I won't deny that it looks like he is forming a different level of Sharingan in that shot, but I also wonder if this isn't an error with animation or some other detail that was overlooked.  It's good so I'll give you that, but it's not entirely convincing.

I don't think it is a error in the animation, it's to close to the Mangekyou. I think it might be the reason from earlier, that he didn't have enough stamina/chakra at that point to use it properly, so it would have to be a dier situation for him to use it. It could be a form of easter egg, but that seems weird.
But I definitely do not have the answer, my friend just saw it, and it so weird why it show up here.

@SimonRotendahl even though he awakened the Mangekyou when Rin was killed, the Jutsu Kamui took time to be mastered by him. So in the fight with Zabuza he uses Mangekyou for its better visual powers like seeing chakra run through body but he can't use Kamui to escape in that fight.

Really looks like an MS, but when I zoomed in it just seemed the pupils became bigger for some reason. I could faintly see tomoe still present, without the lines in between each like Obito and Kakashi's MS. I think the problem is that they made the pupil bigger, yet didn't move the tomoe accordingly, thus being very close to the pupil and from afar looking like a Mangekyou Sharingan. This is what I'm speculating.

I think the only real reason here is retcon. The Sharingan history is one of the most retconed plots in the Narutoverse and the Kakashi-Rin-Obito relationship is up there too. If what is being suggested by these answers and comments is true, then we have to ignore the fact that Kishimoto admited not yet having a design for the Mangekyou Sharingan for the scenes that show Itachi using it on Sasuke without the design we now know. Because of that, we can infere that at the time kakashi was fighting Zabuza, him having the Mangekyou too was unthinkable. Not to mention that when he truly first used it against Deidara, he spent a good hour "working" on his new Sharingan (see image below), so even at the point it still wasn't defined that he had awakened it in Rin's death.

Now, if we MUST make it work for the sake of the Narutoverse, even then we can't presume that those were his intentions when fighting Zabuza, simply because there was no point in using his Kamui in that specific situation.
About his ability with it, yeah, he probably did use it before his fight with Deidara simply because he knew what his eye would do. Since he's not an Uchiha, he had no way of knowing the details of the Mangekyou's power (other then watching Itachi, which was not helpful since their eyes didn't have the same jutsu) without testing on a tree, or a rock. He did faint afterwards, but it wasn't after a single use, he spent a lot of time trying to sever Deidara's arm and even "Kamui'd" his Jibaku Bunshin (Suicide Bombing Clone) entire explosion away.

In kakashi's fight with deidara (episode 29) he references using it before so I think it's safe to assume he has at least practiced the mongekyou sharingan before this fight

He awakened when he killed rin, but he learned about the existence of the mangekyou in the first fight with Itachi, i think kakashi maybe have trained using this fight as "inspiration"

How Kabuto could reincarnate or manifest Hidan (in an anime filler)?
In episode 290 of Naruto Shippuden, Kabuto creates Hidan from thousands of tiny snakes. But by looking at the eyes of manifested Hidan, it seems like an Edo-Tensei. And Kabuto mentions it himself.
Hidan isn't dead! Then how can he be reincarnated? What Jutsu is that??
In the manga of course there is no confusion..
But for that episode I am trying to find the logic. Do you have any thoughts?

No idea for as far as I know. They didn't give much explanation and the whole filler saga looked like someone chewed on some mushrooms while writing it, so I doubt we'll ever get an explanation.

Related

how did I miss that question? @JNat, the problem with these duplicate question is, the search goes by 'string' in question title and tries to bring related stuffs.. When I posted the question, I didn't get this question as relative!

@InfantPro'Aravind' That's because when the site first started, people were a bit over eager in their use of the spoiler block in questions which makes them near impossible to search.  It's getting better though!

@MCeley, I hope so

I think Hidan can die (by hunger, etc...), but not be killed. (by someone else using physical attacks)

The Hidan in that filler is not necessarily the real Hidan. You said it by yourself "Kabuto creates Hidan from thousands of tiny snakes" which proves my point here. In Naruto we see many things created from snakes, in this case, It is Hidan.
The directer of this filler tried to make his story interesting but he failed miserably as you can see. This filler overlaps with the real story making the answer for your question not very logical. This is as far as you can get with this event.

The reincarnated Hidan was like a clone created by Kabuto from the real one's DNA, and also it wasn't like the other Edo Tensei, he died later without being sealed.

clone makes the most sense. Like orochimaru.. essentially all the orochimarus we see are just pieces of him manifested into something that looks like the original. We see this when sasuke revives him from anko mitarashi's shoulder during the 4th great ninja war.

this is just an opinion, but hidan never died in the first place. I mean, sure, he got blown up, but he never died, since he is immortal. maybe hidan's consciousness was put into the body that kabuto created with some sort of mind transfer jutsu.

By a bunch of snakes and a scroll, to revive a real corpse through edo tensei you need their dna for it
that was just a clone of him cultivated from his cells

Apparently Hidan can die from malnutrition, so one can assume that while he was trapped in that hole that Shikamaru dug for him, he eventually and inevitably died from said cause. That's the only explanation that I can give as to how this even makes a lick of sense since I'm re-watching the series and just got to this filler episode, haha.

Can multiple people/animal eat a single Devil Fruit?
Provided, Chopper eats the Devil Fruit along with the other deers, will they all have the Devil Fruit ability, given that acquiring the ability only requires a single bite?

Possible Duplicate or just related: http://anime.stackexchange.com/questions/906/does-devils-fruit-power-gained-depend-on-how-much-of-it-is-eaten

Those are different fruits. They just fall within the same animal race, but are still different animals. With the sisters, you have the King cobra fruit and the Anaconda fruit. With the Tontatta you would have the Rhinoceros beetle fruit and the Giant Hornet fruit.

From the One Piece wiki:

Only one bite is needed for the user to gain the power of a Devil Fruit, after which the Devil Fruit becomes a simple, useless, disgusting fruit

So I would say that the answer is no. Only one person/animal gets the ability.

out of curiosity, if two people eat half by half together, What will happen ??

@NaingLinAung Whoever takes the first bite gets the power. There will always be someone who swallowed first, if not by a millisecond, than by a microsecond.

When a Devil Fruit is bitten (even once), it loses its powers PERMANENTLY or until the person who bit it first dies. When the person who first bit it dies, the Devil Fruit returns to its normal state, so someone else can get the power. If Luffy died (what a sad thought!) then the Gum Gum fruit would be able to give someone else Gum Gum powers. So only one person at a time can have its power, not more than one.

Wait, so if some kept half of the Gum Gum fruit (Luffy only ate half in this theory), then killed Luffy, the other half would re-gain its power?

@ShadowZorgon No, because that half comes from the same fruit it would already have lost it's powers. The Gum Gum fruit would 'respawn' in another closeby fruit (without powers)

Why didn't Naruto learn the basics of chakra control?
In Naruto, shinobi battles last a very long time consuming lots of chakra.  Even though Naruto has a lot of chakra, he ignored the basics and started learning high level techniques with Jiraiya.  Even though this wasn't a bad thing, he just kept learning higher levels of techniques without using the basics, causing him to waste more chakra for high level jutsus.
Why hasn't Naruto learned how the use the bare minimum the start his jutsus?
Know that if he did that, he wouldn't have had to rely on the Kyuubi's power and would probably be able the do rasen shuriken one more time, or at least have some chakra left over for retreating or finishing off the opponent.

Given that Naruto is a slow learner and the possibility of Kyuubi's interference, Jiraiya realised it would take him a long time to learn the chakra control, and decided that the benefit gained from it is not worth the time spent. Since Naruto has abundant chakra reserves, Jiraiya decided that learning how to tap it is of higher priority than chakra control.
Moreover, many of the times when Naruto learned a new technique (Frog Summoning, Rasengan, Rasenshuriken, Sage Mode, Kyuubi chakra mode), he had to do it within some time limit, so he could not take his own sweet time learning chakra control, and hence, sticked to his original learning method. It is possible that Jiraiya did teach Naruto some chakra control during the time they travelled together, but there is not enough evidence of this happening.
Note that when Naruto began training with Ebisu during the one month training break before the Chunin exam finals, Ebisu did tell him to learn to use his chakra more efficiently. However, after Jiraiya took over his training, he asked Naruto to focus on power rather than control, since he felt that style suited Naruto better.
Chapter 90

Chapter 92

However, he can just 'cheat' by using many shadow clones.  So why doesn't he just do that.

@Blue: Because it's risky to do without Yamato (or Hashirama) around. MANGA SPOILER!!! Perhaps now, after he's friends with Kurama.

@Blue I don't get it. After he learnt about the multiple shadow clone method to speed up training, he tried using that everytime, unless someone told him he could not use it. With Sage Mode, he was asked to not make more than 4 clones, and later with the Kyuubi mode, he was asked not to make any clones at all. So it is not like he doesn't do that, he is not "allowed" to do it for other reasons.

Yes but this is for basics meaning he won't waste so much chakara for jutsus like rasen-shuriken, and since Naruto has so much chakara, he just need to mass clones not to the point in where he will turn kyubii but rather just to get the experience.  All Naruto is doing is learning how to manipulate Chakara from himself, rather than using the Chakra around him.  The reason Sage Mode was limited was because of the risk(if one clone turns into a frog he turns into a frog) also the difficulty of hitting the clones.  The point is, that he can do more jutsus when he controls his chakara.

I get it now, so you are saying he could get over the "it takes too much time to learn" by using mass shadow clones. There may be three reasons why he doesn't. 1. Nobody has pointed that out to him, and even though he has become smarter, he is still too stupid to figure that out himself. 2. Author did not see much value in pursuing that thread now. Naruto has become too badass now, and it would be lame to pursue an arc like that. 3. Author did not think of it this way. He is a human after all with weekly deadlines, he cannot think of all possible scenarios. :)

By the time he is likely a jounin by The Last: Naruto the Movie 2 years after the Kaguya fight, he can form a rasen shuriken with a single hand. His control was so great and progressed so much during the war, he was able to share chakra with everyone. Basically, the Kyuubi was in the way and when he was no longer in the way, his abilities shot up and his control became so much greater because he had to train in 'higher gravity'.
Conclusion, he was constantly improving his control, but the Kyuubi was interfering throughout most of his life so he had to gain more control than the average person to make up for it. When he no longer had interference, it was no longer a problem.

kinda makes sense

How did Toneri Otsutsuki move the Moon towards the Earth?
We know that Toneri tried to use the Moon to destroy the humans. How did he move the Moon? Did he have any control over attraction and repulsion like the Naraka Path?

He used the tenseigan to move the moon. The tenseigan is formed by a combination of the otsutsuki and hyuga chakra. Toneri was from the otsutsuki clan so he got the tenseigan by implanting Hanabi Hyuga's byakugan. In 'Naruto Last: The Movie' they said that the tenseigan is strong enough to move the moon.
He said that Hamura told his descendants to destroy the Earth if the shinobi works fell apart. So my guess is that the tenseigan is a dojustsu made especially to do that. So maybe it's ability is to move the moon.

Did Luffy really kill Arlong?
Hody said Luffy and the Straw Hats killed Arlong and his crew. As far as I know, Luffy never killed someone. I'm a bit confused

Based on the wiki, Arlong is still alive. Also, based on Reddit, looks like this is from chapter 634, but from unofficial/incorrect translation.

Also, might be helpful if you could also mention if you're reading/watching from official translation or scanlation/fansub, to clarify the misunderstanding.

In anime, we are shown Luffy knocking out Arlong, after that it's assumed all of his crew is taken to Navy prisons but in the Impel Down arc, we don't see Arlong.
Luffy believes and like people who are really passionate about achieving their goal, even if they are his enemies. It is seen clearly, as Luffy always gives them a second chance to get better and achieve their goals.
Even if we think Luffy killed them, why would Jinbei join the Straw Hat pirates? Arlong is like a brother to him though they have their differences. So from all this, we can say Arlong is not killed, at least not by Luffy.
One Piece is all about making people believing in themselves, their own ideas and pursuing them no matter what. These are a few situations which proved that:

Koby
Zoro's fight with Mihawk
Dragon's Revolutionary Army
And many more .....

Various sources claim that Luffy never killed anyone, leaving them another chance to achieve their dreams. Beyond that even Oda himself seems to have said so.
One Piece Fandom Wiki / Arlong
lists Arlong as "Alive".

What is the logic for the representation of the various chess pieces?
In Naruto, Sarutobi Asuma gave Shikamaru a puzzle that his father Hiruzen had previously given him. While playing Shogi with Shikamaru, He asked if Shikamaru could figure out what piece represents the Hokage. Which of the chess pieces do?
Do all the other chess pieces have similar representations? Because Asuma mentioned that Shikamaru seemed more like a Knight and himself like a Pawn. Whats the reasoning behind this match up?

In the anime it is explained that shikamaru is a knight because in a way knight moves different than other pieces he thinks differently & asuma is a kind of guy that jumps in and sacrifices himself like a sacrificial pawn which happened later in shippuden.

Most likely, the metaphor is not so well thought out that every shogi piece actually represents something.
I looked through some clips to get the following info.

Most of this, if not all, comes from episode 77: Climbing Silver, which I skimmed after writing this answer. The official subtitles differs from what I've quoted, but not so much that I felt inclined to fix them.

As Asuma says, he himself is a sacrificial pawn. True to this, he sacrifices himself in battle in order to give Shikamaru a chance to formulate a strategy to defeat their foes.
Asuma says Shikamaru is the knight. Of Shikamaru, he says:

This game is a must for people like you who are good at coming up with strategies.

In episode 71: My Friend, Asuma explains:

Although weak in strength, a knight can advance by jumping over pieces. The unique movement represents your flexible thinking.

Asuma likens the Climbing Silver, a strategy where pieces are deliberately sacrificed, to a sacrificial assault to break through enemy lines.
Shikamaru likens Hidan and Kakuzu to a rook and bishop (or simply great pieces in official translation), and says that to capture those pieces, bait is needed.
The king is, of course

 The children of the village, who must be protected at all costs to ensure the future.

Asuma states the following:

Shogi allows you to work through various situations by utilizing each of the piece's individual attributes.

As far as I'm aware, there isn't much more information than this regarding which piece is what. The last quote is important though. We can guess that the other pieces, with their differing movements, simply represent in general that there are different types of shinobi with differing abilities and strength. This is a game to represent combat, so we can guess that non-combatants are not represented and all shogi pieces represent shinobi (excepting the king). Extrapolating from that, we can guess supply lines and other support positions are not directly represented in the game (If there is a way to regain captured pieces, that could be a way to indirectly represent medical ninjas). We can guess that the Hokage is represented by the strongest piece.

If anyone wants to dig further: list of all Shogi matches in Naruto can be found here: https://shogiwar.webs.com/Shogi_War_Page/anime.html Can confirm the match in episode 68 offered no additional information to the Shogi metaphor.

I think Shikamaru would be more of a knight because its move pattern is different than other figures, he can jump over them - sort of similar to the way Shikamaru thinks.
Asuma is a pawn, a simple guy/soldier who jumps in to help and sacrifices if necessary.

Why does Naruto’s anime and manga have huge differences?
I started to watch Naruto and I didn’t read the manga. Some people told me that they have so many differences and its even like a separated version. Why is it like that? I searched it on Google but couldn’t find anything.

The only difference are the fillers. Anime has a lot, LOT, of fillers.

Related to the above comment: Which episodes of the Naruto anime are core plot and which are filler?, Why make filler episodes?, Why are there so many fillers in long-running animes?, and their related questions (on the right sidebar)

@EroSɘnnin ohh i see

almost every anime will be a bit different from its manga in order to attract the manga readers cause if everything is exactly the same, there'd be no incentive for them.

The manga was ongoing when the anime was airing so they had to make a lot of fillers while waiting for new chapters

Yes, there are indeed some differences, but to call it a separated version? I think not.
In most anime, 1 episode tries to cover around 2-5 chapters of the manga. Quite often there is too much information or things going on in the chapters to properly cover in 1 episode of ~19 minutes. This means they have to 'cut down' some of the manga's content.
Cutting the content as such often leads to lacking some build up, or additional information. Which, especially if you did read the manga before, makes it feel like a whole different story. Or a lacking story.
Besides these differences, Naruto also features quite a few fillers. As Aki Tanaka mentioned in the comments as well: Which episodes of the Naruto anime are core plot and which are filler?
However, those fillers can be considered as additional content, as this does not replace content. But more about that is explained in Why make filler episodes?

In which episode of the anime did Aokiji (Kuzan) and Akaino (Sakazuki) fight?
Coz' it wasn't revealed in the anime. I want to watch the fight between Kuzan and Akainu again, or maybe I missed that episode.
In which episode of the anime did Kuzan and Akainu fight?

The fight is shown in Episode 583, when it was told by Smoker-san in the midst of the Punk Hazard Arc.

According to Smoker, the battle between these two was so ferocious that it literally changed the weather of Punk Hazard Island. Akainu ended up as the winner, but had sympathy enough to spare Aokiji's life in spite of it being meant as a battle to the death. Unfortunately, Aokiji did not escape unscathed. He parted from the battle with a staggering level of scars and with his left leg reduced to a stump. Though crippled, Kuzan used his Devil Fruit powers to generate a replacement limb out of ice.

From Kuzan article on One Piece Wiki
Episode 583 preview on YouTube showing the scene.

The fight has never been shown: it happened in the 2 years gap and at the moment we just know it was on Punk Hazard and that Akainu won after 10 days of fighting (I hope there will be a flashback at some point showing the fight).
This is a video taken from episode 570 in which Jimbei explains the situation.
The fact that they fought on Punk Hazard is explained in episode 582.

How many demon forms does Mirajane have?
As what I've known, Mirajane has only 3 forms :

Satan Soul
Halphas
Sitri

I wonder if how many demon forms does Mirajane have (not yet discovered)? Is it three forms only?

In the meantime, Sayla was taken over too.

According to  Mashima, says that there are 72 demon forms of Mirajane, but It was not yet revealed in manga and anime,
Mashima has went an interesting way with Mira's powers.
Though if you know about demons from the Goetia list or other animes you probably already sort of know.
Lisanna has things like Animal Soul: Rabbit, Animal Soul: Tigress
Elfman has Beast Soul: Weretiger, Beast Soul: Lizardman
Animals and Beasts.
Though in Mira's case of course she'll have demons for her forms, and Mashima has decided to get them from the Ars Goetia list.
So it'd look like for her, Satan Soul: Sitri, Satan Soul: Eligos etc.
Here's the list of demons:

King Baal (bael)
Duke Agares
Prince Vassago
Marquis Samigina
President Barbas
Duke Valefor
Marquis Amon
Duke Barbatos
King Paimon
President Buer
Duke Gusion
Prince Sitri-Shown
King Beleth
Marquis Leraje
Duke Eligos
Duke Zepar
Count/President Botis
Duke Bathin
Duke Sallos
King Purson
Count/President Marax
Count/Prince Ipos
Duke Aim
Marquis Naberius
Count/President Glasya-Labolas
Duke Buné
Marquis/Count Ronové
Duke Berith
Duke Astaroth
Marquis Forneus
President Foras
King Asmodeus
Prince/President Gäap
Count Furfur
Marquis Marchosias
Prince Stolas
Marquis Phenex
Count Halphas
President Malphas
Count Räum
Duke Focalor
Duke Vepar
Marquis Sabnock
Marquis Shax
King/Count Viné
Count Bifrons
Duke Vual
President Häagenti

72 Demons
link to list: http://en.wikipedia.org/wiki/List_of_demons_in_the_Ars_Goetia#Prince_Sitri

unfortunaly, while this may be a good answer i have to give a downvote as this was more or less copied from a "Fairy Tail Theories" forum. i would gladly remove my downvote if you can quote Hiro Mashima's comment to validate as i can't find a credit source on the forum you linked to

Satan Soul

Demon: Halphas

Demon: Sitri

I've read some information about the Mirajane's Take Over magic:

Macro (命令, マクロ Makuro): Unable to fully take over an Etherious, Mirajane took over Sayla's Curse, allowing her absolute control over something, from inanimate objects to even people. She uses this to command Elfman to come to where she and Lisanna are.

For now, she had 3 demon take over. She wasn't able to take over an Etherios where she fought  Layla. This is where Layla's true form reveal.

we got a new one yesterday

What factor led Zoro to accept Luffy as Captain?
Why does Zoro respect Luffy? When they first met, he wasn't really pleased about Luffy.
Zoro was always quite a loner, even now in the crew.
Does he accept Luffy as his captain because of his dream? Or because he is stronger than him? (even though their strength is similar, I think Luffy is still stronger)
On Thriller Island, we saw how big his support for his captain was, when he took all the pain, to save them all!

Zoro and luffy have mutual respect since the moment they met. Everybody called zoro a demon but luffy decided to think otherwise when he saw zoro eat the ricecake and heard he was in trouble for helping the girl. He saw zoro's true colors back then. The same goes for zoro when he hears luffy punched helmeppo in the face for betraying him.Their kind heart and demonic powers makes them respect each other. You can see zoros respect from chapter two when he defeated the marine with the axe. Luffy didnt need to say a single word and zoro obeyed already after having joined the crew for a few seconds

Also, he probably feels like he is indebted to Luffy, as Luffy saved him from execution, giving Zoro the chance to fulfill his dream. I think Zoro feels like he owes Luffy to help him with his dream, while chasing his own. Following Luffy also gives him a better chance of fulfilling his dream as he would encounter stronger opponents on the way.

Adding to everything everyone said, it comes down to he was about to die and Luffy gave him a way to continue fulfilling his dream without sacrificing his morals. Over time he gained respect but in Water 7 he reiterated to Luffy if his choices ever get in his dream's way he'll leave the crew.  This was however counterpointed by his choice to learn from Mihawk where he said he'll give up his dream if it mean helping Luffy.

I just rewatched the beginning and it makes is surprising clear.  At that time everyone knows who Zoro is, it is implied Zoro could kick Luffy's ass, and everyone looks down on Luffy until they get confused by his devil fruit power.
Zoro is a demon.
Zoro is however a very honorable demon.  He signs (figuratively) a contract to torture himself to protect someone he views as innocent from someone he views as completely dishonorable.  He follows that contract twice: once to honor the efforts of the girl he was protecting after the vermin mistreated her; once when the vermin clearly broke their contract.
He, while powerless, signs a contract with Luffy.  As long as Luffy frees him and supports (or more accurately does not get in the way of), Zoro's dream to become the worlds greatest swordsman, Zoro will be part of Luffy's crew.  Even when Zoro finds out that Luffy doesn't really have a crew at all, he shows a ting of apprehension but no willingness to break his contract.
As time continues, Zoro increasingly grows to respect Luffy above and beyond the requirements of his contract. He will not leave Luffy, however, unless his contract is broken.  This would have likely occured if Luffy was not strong enough to proceed into the New World and provide Zoro the opponents he needed.
I guess when you make a contract with a straight shooting demon, expect him to follow through in incredible ways.

Luffy and Zoro are not very different when it comes to fighting skills and strength, so if luffy is not strong enough to go on then Zoro will not be able too either. That's what happened after the war of the best. The only other possibility is that Luffy decides to give up on his dream which I think is even less possible :P

Pretty sure he's forgotten the contract. He stated during Water Seven that if Luffy allowed Usopp back into the crew casually, he would leave the crew too. That would be a breach of contract

I guess he accepts him as captain because of his kindness, when he was about to be executed, the soldiers hold up their rifles and open fire, and Zoro thinks how he cannot die, and remembers Kuina. However, before the bullets can reach them, Luffy leaps from the Marine base and uses his rubber body to block the bullets and send them flying. When Zoro is shocked and asks who he is, Luffy responds that he is Monkey D. Luffy, and that he will become the Pirate King.
He wants to help Luffy to become Pirate King not because he asked him to join the crew but he was willing to help and to meet Dracule Mihawk while they're sailing .
Click Here:
First Meet

It is his trust in Luffy and Luffy's dedication to his dream. He believes Luffy has what it takes to be a Captain.
Zoro believes in Luffy, he believes that Luffy would go to any length to keep his word. He sees this quality the first time they met each other. He said that Zoro was his comrade and he fought for him, honoring his word. He also sees that Luffy has a big dream, and he was serious about it. Plus, he believes in Luffy to be Captain.
This can be seen when Luffy fights Usopp. Luffy had to beat Usopp and leave him, which was very hard for Luffy to do, but Luffy does it as a Captain. Zoro remarks that it's the burden of the Captain, and the rest of the crew relies on him to bear it (read more about it on the  wikia).

The fact that Zoro cannot bear Luffy's pain (as depicted above) is why he will never be the Captain. Besides, why would he want himself as the Captain, if he is the one who joined Luffy's team? By so doing, I think he is fully aware that the Captain of Luffy's crew is Luffy himself.

What made Samehada team up with Bee?
After Kisame passed away, heck, even before he passed away, Samehada seemed to be attracted to Bee. What drove it to do so? The ownership of a sword only changes when the new owner defeats the old owner, isn't it? Or am I getting something confused here?

Found the answer in the Wikia article on Samehada. The ownership is actually based on Samehada's personality. It seem to have its own conscious (emphasis mine):

Samehada is unique for being a sentient weapon that gains nourishment from the chakra of others and as such, the blade is at its happiest when engorged with chakra that possesses both a distinctive and pleasant flavour. It apparently greatly enjoys Killer B's chakra since, according to Kisame, it tastes like octopus. However, it has shown displeasure towards fire-natured chakra, stating that — according to B — it's far too hot. Being capable of conscious thought, Samehada chooses its own user, an exclusive process that has often resulted in it being thought of as notoriously picky. If someone it disapproves of attempts to wield it, spikes protrude from the handle in order to force them to release their grasp, at which point Samehada will make efforts to return to its chosen owner. Even if it did betray its former owner for a more powerful wielder like Killer B, the blade was at least close enough to Kisame to mourn his death.

Why does Sasuke still have the Rinnegan?
Hagoromo took back his Yin and Yang chakra from Sasuke and Naruto respectively (in chapter 690). So if the Yin chakra was responsible for the Rinnegan development in Sasuke's eye, why didn't it change back into his original eye after the chakra was taken back? Why does it become permanent?

Well.. I thought Sasuke obtained the rinnegan after receiving chakra from Hashirama in the battle field since Hashirama is a reincarnation of Ashura and all what matters to obtain the rinnegan is to have both Ashura's and Indra's chakra.

Well, we have seen several instances where even losing Six Paths Power still makes one stronger than most, as described by Kakashi after he obtained Obito's power.  I don't remember the exact chapter, but right after he awakened Sharingan in his natural eyes from Obito transferring his power, Kakashi says something along the lines of the eyes being stronger after Obito played host to the Ten Tails.  One could also argue that having the completed chakra of the Six Paths was only a requirement to awaken the Rinnegan, not keeping it.  However, I must stick with whatever facts that I can see and those are thus;  but first.
Spoiler warning, just in case you haven't read past chapter 690 as mentioned in the OP's question.

 In chapter 696, after Kaguya was defeated and the Six Paths Yin and Yang symbols had returned to Hagoromo, we witness the final fight between Naruto and Sasuke at the Valley of the End. In this fight, Sasuke was still wielding his Rinnegan, but more importantly for the evidence involved, Naruto was still using Six Paths Sage Mode. That being said, it leaves little room for interpretation that the two of them must still have Six Paths Chakra of their own.

 Now the room we do have for speculation comes here where we must decide whether they still have these powers, because
 A. When Hagoromo regained the seals on his hands, they were just the seals for the Six Paths Chibaku Tensei and nothing more. Or
 B. Even though Hagoromo took his powers back, having been exposed to the Six Paths chakra has awakened their natural ability to use it, since Sasuke and Naruto were the reincarnated Indra and Asura respectively. After all, Madara was able to awaken the Rinnegan by introducing Hashirama's cells into his own body unknowingly, which means introducing Asura's chakra into himself. After it was integrated, he didn't have to continuously inject Hashi's cells to keep the Rinnegan.

If you see any other part of your original answer that has changed meaning after my edit, feel free to edit it. You can refer to on your original revision here: http://anime.stackexchange.com/posts/18662/revisions (which is also accessible from "edited XXX hours/days" link) above

Alright.  Thank you, I didn't mean to come off as callous and in fact I very much appreciate the work you do in correcting my sloppy grammar.

Really, Sasuke ' s Rinnegan was awakened the same way Madara's Rinnegan had been awakened. When Sasuke wakes up from his talk with Hagoromo, we see Kabuto healing him using some of his own body's regenerative properties.
Kabuto had, long before this, already fused Hashirama ' s cells in his own body and by fusing his flesh into Sasuke, that once more uses Hashirama to combine Indra and Ashura's flesh which is what awakens it.
However as Madara said, it still took years for the flesh to take effect, so likely the exposure to Hagoromo's Chakra in his seal he gave them managed to jump start the effects.
I don't know for sure, but I would think it would make sense that having such a long process suddenly happen in just those couple of minutes could have complications or mutations, which may be why Sasuke only got it in 1 eye, and why it's in the same side his yinyang seal is held.
Given that, it's possible the right side may eventually catch up and activate. Also, after Madara activated his own Rinnegan, he's never seen deactivating it back to his normal Rinnegan until he retrieves it from Obito and Zetsu, whom got the eyes from Nagato. So it may not be something one can so easily deactivate like the normal Sharingan eyes. He may have to awaken and master all 6 paths before he can deactivate them.
Considering these facts and any other complications that could have arisen from the Sage's abrupt interference with the natural development, and Sasuke may never be able to properly activate and deactivate a matching pair of eyes whether they're Sharingan or Rinnegan. (Except perhaps when he's much older, like grandpa to Sarada kids older)

In the image you posted, when Hagoromo said "Now I only have to retrieve all of you", he didn't refer to Sasuke and Naruto. He referred to the nine Bijuus. Therefore, Sasuke & Naruto didn't lose any of the Rikudo powers (Rinnegan included), simply because Hagoromo never took it back from them.

the reason sasuke still has the rinnegan is actually really simple. once you have it, its permanent. look at madara for example, he unlocked the rinnegan before he died, and before he had hashiramas cells.yet after he became an edo tensei, he was still able to use it after re obtaining his eyes from zetsu.

Do you have any sources to back up your claim?

@Makoto I think the fact that Pain used the Rinnegan should be enough proof. Pain never had Indra and Ashura's chakra given to him, yet he was still able to use the Rinnegan. This would suggest that the chakra was only needed to awaken the eye.

I agree with most of the reasons people put. But i think the reason why Sasuke kept his rinnegan was that when he and Naruto last fought, they lost their dominant hand but then started bleeding. As they were bleeding, their blood join and kind of mixed part of Naruto's and Sasuke's chakra together.
I don't know if this is correct or not so ima just  get it from memory. I remember that somewhere in the Naruto Shippuden series, someone said that when a Uchiha (Indra's descendants) obtains the chakra of a descendant of Ashura. The user unlocks the rinnegan. Im pretty sure that Madara didnt get it right away because he only had a little peice of Hashi's chakra.

Hagoromo's Yin power unintentionally became a catalyst to speed up the Rinnegan forming process, as stated by Madara when he awakened the Rinnegan prior to his death, meaning that it takes a long time for the Rinnegan to form. Madara even told Obito "[...] even if you don't gain the Rinnegan [...]", and this was after he healed Obito with White Zetsu's skin. The presence of Hagoromo's chakra shortened the Rinnegan formation process for Sasuke, and even then it was only in his left eye. I believe his right eye will become a Rinnegan later in his life.

i would like to talk about the truth. Sasuke's Rinnegan has nothing to do with hashirama's cells
as hashirama ceased being a transmigrant upon his death. hagoromo said that hashirama and madara were the previous transmigrant. key word WERE they no longer are transmigrants Naruto and sasuke are the current transmigrants as such Hashirama's cells no longer carried the potential to awaken a Rinnegan
sasuke's Rinnegan is solely because Hagoromo gave Sasuke six paths power. naruto's six paths senjutsu is solely because hagoromo gave his six paths power to naruto. now people assume he only gave the each half of his power but this is a lie he gave them both both halfs of his power. the only reason Naruto didn't gain a Rinnegan was because he doesn't have a sharingan. and like wise sasuke only has 1 Rinnegan because he lacks the senjutsu of the six paths if Naruto and Sasuke were to exchange DNA Sasuke would awaken a second Rinnegan, Naruto's body would than acclimate to the full required genetic halves of the sage of six paths and eventually awaken a Rinnegan

Why didn't Tobi use Kamui when Minato used Rasengan?
During the fight between Minato Namikaze and Tobi (in episode 248 The Fourth Hokage's Death Match of the Naruto: Shippuden anime, or chapter 502 and 503 of the manga), Minato escaped from Tobi's Kamui, despite having been caught in the technique unexpectedly.

3 minutes and a few seconds later into the episode, the two ran towards each other. At an extremely close distance, Minato pulled off a Rasengan. Considering the bright aura and the sound it makes, I'm pretty sure Tobi noticed it.

Tobi let the kunai that Minato had thrown pass through him. So instead of using Kamui to let Minato phase through him, why did Tobi keep going? Minato had already escaped from Kamui once, and that was when he was caught unexpectedly.

I have no idea, but your current question doesn't have any close vote. What I have been doing so far is to make the question look better. I don't read Naruto so I can't really tell whether this question is subjective or not. However, my uninformed impression of this question is that it is a bit strange to use a skill when you know your opponent can avoid it.

In chapter 502 from page 8, Tobi fought with Minato. As nhahtdh commented, there is no reason to use the same jutsu twice when the opponent can avoid it.
The image below shows Minato's inner thoughts moments before they clashed against each other in the second image.

In the second image you posted above, if you take a closer look

You can see the kunai passing through Tobi. If you are not aware, Tobi was actually using Kamui to let the kunai pass through him. However, to attack, Tobi had to solidify his body. Tobi couldn't attack and defend at the same time with Kamui. Correct me if I am wrong here.

As you can see from the above picture, Tobi touched Minato and was going to attack. I don't know what jutsu he was going to use, but Tobi was confident that he would win, so his whole body was solid and he was not using Kamui.

Hiraishin Level 2 was faster than Tobi's attack, and Boom. Rasengan.
So the reasons why Tobi did not use Kamui to let Minato's attack pass through him:

Using the same jutsu twice against an elite shinobi is foolish, unless one has well-grounded confidence that it will work, or has another motive.
Tobi was confident that he was going to win this fight, as you can see on third picture.
He was unaware of Hiraishin Level 2. As you can see, he was surprise when Minato jumped to the kunai.

Hiraishin level 2. Not Hiraishin

IIRC all the Hiraishin Jutsu used by Minato used Marked but stationary Kunai but that Kunai was moving.

Another reason would be that Flying Raijin level 2 and above is faster than any dojutsu can read. Plus, Obito didn't even expect Minato to use the kunai he evaded nor use Rasengan again.

Why didn't Dabura attempt to turn Buu to stone?
In the DBZ episode Meal Time, why didn't Dabura even try to turn Majin Buu into stone? I'm not saying or implying it would have worked, but it seemed more likely to work than anything else he did.

In the episode Meal Time, Dabura actually did try to turn Buu into stone by using his spit. But when he did, Buu dodged the attack, then turned him into a cookie and ate him.
If Buu was hit by the stone spit from Dabura, he would be able to regenerate after breaking like Piccolo did.

In desperation, Dabura tries to turn Buu to stone with his spit. Buu
  dodges and turns him into a huge cookie with his Chocolate Beam,
  eating him afterwards.

This is found on the same page that you posted in the question.

I seem to have missed that sequence... the description came after Ero's edit which altered the link
