Is Gohan Beast a super saiyan transformation, or can anyone get it?
Gohan's last transformation changes his color, but so do other transformations, which arent saiyan-only transformations, such as Ultra Instinct or Ultra Ego. So,
Is Gohan Beast a super saiyan transformation, or can anyone get it?

It is not a super saiyan transformation.
It is more of "Next" transformation of Ultimate Mystic Gohan .

Ultimate Gohan is a transformation achieved by Son Gohan after Elder Kaiōshin unlocked his potential. Despite appearing to be in his normal state, Gohan, in actuality, is using the power of Super Saiyan 2 without the burden the latter transformation places on his body. As a result, Gohan is able to achieve a power beyond Super Saiyan 2 and even Super Saiyan 3, ultimately being even with Super Saiyan Blue after constant training.

That's cool, but that isnt Gohan's last transformation.

Did Garou surpass Boros' power by chapter 165?
As far as I remember, Boros's most powerful attack was an energy beam that when deflected caused an Earth wide wave over the entire ocean. However, Garou's attack in chapter 165,

 it caused the entire Earth to bend

That has to be more powerful than Boros' last attack right? Or was there another attack from Boros which was more powerful?
Did Garou surpass Boros' power by chapter 165?

Why didnt Genos' core fuse with its past version?
In One Punch Man manga chapter #168,

 Saitama returns to the past and fuses with his past self. His clothes also fuse, so the naked Saitama by fusing with the dressed Saitama appears with a suit which is half complete, with a hole in his private area. So if Saitama (human/organic) and clothes (inorganic) fuse with their former versions,

Why didnt Genos' core fuse with its past version?

Since this is the latest chapter to date, we can only presume the question will be addressed in further chapters...

@RigaCrypto there are several other possible answers such as, a logical explanation, an answer by one of the authors, Murata in particular uses to answer questions from fans and sometimes he gets back with an answer from One, a continuity mistake, etc.

Sure, but if the answers spoils something that is about to happen or be explained in the manga, he won't answer... that is why I said that we could get an explanation with the story is progressing.

When Granolah and Gas were granted the wish of being the strongest in the universe, did they become more powerful than Beerus?
Both Granola and Gas at some point of the manga asked to be the strongest warriors in the universe. Does this mean the dragon turned them stronger than Beerus, or is Beerus as a god of destruction out of the equation?


text:
Is Black Freezer the strongest warrior in the universe now?
So in chapter 87 of the manga,

 Black Freezer defeats Gas, who was supposed to be the strongest warrior of the universe at the moment, though not sure if he was at full strenght, and Goku and Vegeta.

Does this mean Black Freezer is the strongest warrior in the universe now? How about Beast Gohan? Did he surpass Beast Gohan too?

Why did Kichimura know Kaneki was going to mutate into Dragon, and why did he say he provoked it?
In the anime series of Tokyo Ghoul:re 2 , episode 12, Kichimura says he provoked the appearence of Dragon. In some former episode, when Kaneki mutated into Dragon , he was expecting it, as if he knew it was going to happen, he called it "dragon", and he said something like he expected dragon to destroy everything.
Why did Kichimura know Kaneki was going to mutate into Dragon, and why did he say he provoked it?

Ikr! I'm guessing he knew something about Rize's kagune that many others don't. Tbh the tokyou ghoul re 2 is going way to fast for me to keep up.

'Why did Kichimura know Kaneki was going to mutate into Dragon and why did he say he provoked it?' This might not be clear in the anime but he was behind it all along. That was his plan from the start but how he was able to make Kaneki and Rize transform into a dragon was never fully explained in the manga.

@W.Are: You should leave that as an answer instead of as a a comment, and cite the source.

Kichimura is of the same family as Rize (the washu) but Kichimura is a demi human that got the Q surgery or the surgery like ken's from Kanou to have a kagune. he grew up where Arima and and Rize did, in the hands of the washu Rize was made to reproduce because they wanted a strong blood line and did not want to have kid with humans and have kids like Arima and Kichimura anymore so they made or cloned girls like Rize to bare the chair mans babys. Kichimura fell in love with Rize, as kids they played together and as he started to grow feelings he could not stand the fact that his disgusting old father would be with her and she would have to hold his child so he let her escape and she loved her freedom to much (binge eater). He then watched her for a long time until he pushed a bunch of falling pipes onto her and some school boy (ken), just to keep her closer to himself. It seemed as if Kichimura and Dr Kanou were working together with v as well. We all thought Rize died after that but she didn't and she was used to make Ken into a half ghoul first then Shiro and her sister then she was used to make army's. she was split up in little pieces everywhere but Kichimura knew he could bring Rise back to life through ken eating some more of rize, he would some how get rize back for himelf and the ccg would be taken care of by the dragon so he the leader of v and the last of the washu clan could have the only one he ever loved by his side finally. The 'dragon' seemed to have given life witch is hard to understand but there was also kanou who devoted his whole life to ghoul medical use on humans because he wanted to bring his mum back to life.

Very interesting insight, Could you add some sources to validate the answer? A manga source (like chapter and page or pic could suffice)

@Rumpelstiltskin Most of his answer are accurately taken from the manga although I agree that citing manga chapters is necessary. What I don't agree with his answer is 'he would some how get rize back for himelf and the ccg would be taken care of by the dragon so he the leader of v and the last of the washu clan could have the only one he ever loved by his side finally.' I'm trying to remember but I could not recall this being what he truly wanted. I'll try to reread and provide my own answer.

you should read the fight scene between Kaneki and Kichimura in the manga as i think thats probably got the most information about this question. it has been a while since i read the manga so my comment might of been more my opinion though what the words may have implied. translation can also be different and give you a different out look on the story depending on where you read it.

but seeing that humans are turning into ghouls there could be more of a plot twist that the Washu wanted to turn all of tokyo into ghouls and use rize as the weapon (the dragon)

Why was it so easy for Kichimura to tear the one-eyed owl kakuja apart?
In Tokyo Ghoul:Re 2, episode 2, Kichimura tears the one-eyed owl kakuja apart easily, when she was supposed to be the strongest Ghoul until that point in the anime series. Why was it so easy for Kichimura to tear the one-eyed owl kakuja apart?

Why was it so easy for Kichimura to tear the one-eyed owl kakuja apart? Because Kichimura is not as weak as he makes it seem to be. He is one of the half-humans raised in the Sunlit Garden, together with Arima. As stated here,

Half-humans have highly developed physical capabilities, and I think a good example for this difference from normal humans are Kishou Arima's and Squad Zero's abilities.

Apart from those enhance abilities, Kichimura also became an artificial one-eyed ghoul, possessing Rize's kagune like Kaneki. While not directly stated in the manga, it is heavily hinted that one-eyed ghouls are much more powerful than normal ones. Rize and her kagune's strength is also recognized and this is seen by the fact that she was the one used by Kichimura to become

his 'dragon' after Kaneki, who was temporarily his 'dragon', was rescued during the Dragon War arc

With this and the fact that Kishou Arima is able to hold his own fighting Eto before, it would, therefore, not be impossible for Kichimura to do the same, with the same capabilities as Arima and further enhanced by Rize's kagune.
In addition, Kichimura has the element of surprise, and Eto was not expecting his power. If she knew, she might have been more careful but as seen in that episode, she just attacked head-on and you can clearly see the look of surprise in her face as her kakuja is torn.

Why Goku's Ultra Instinct wasn't awakened in his battle with Broly?
In the tournament of power, Goku was pushed to his limits several times, and he awakened Ultra Instinct Omen, and Mastered Ultra Instinct. But in the battle with Broly (in which I would assume he was pushed to his limits too, since

 not even with Vegeta was he able to defeat Broly in Super Saiyan Blue

He couldn't awaken Ultra Instinct, not even Omen Ultra Instinct, and in the new manga arc we see he was "Ultra Instinct-less" for several years. Why wasn't Goku's Ultra Instinct awakened in his battle with Broly?

I would recommend you edit your title so that it doesn't specifically mention Broly. As it stands, the title is a spoiler for the new Broly movie, which hasn't even released yet.

Ultra  Instinct Goku is the strongest iteration of Goku in the history of Dragon Ball. Goku with that power was capable of easily overwhelming a fighter who rivaled the power of a God of Destruction.Secondly, this skill is something which is so difficult to master that not even Beerus, who is one of the strongest God of Destruction across the Multiverse has been able to master and Beerus has lived for thousands of years.From the movie's perspective there are many reasons why Goku doesn't tap into UI, While Broly is undoubtedly strong, he definitely doesn't rival the might of Ultra Instinct Goku and having Goku use UI against Broly would be a bit ridiculous considering the fact that Ultra Instinct has been regarded as such a complex skill and having Broly go toe to toe with it wouldn't make sense.The movie obviously wanted to make Gogeta canon for the sake of pushing merchandise and to cater to fans and they decided to use the fusion route.Even from the Movie's perspective, Goku isn't pushed to the same extent he is against Jiren. While Broly does defeat SSJB Goku, Both, Vegeta and Goku instant transmission out of there and then spend time fusing and go back. When Goku had to fight Jiren, despite getting beaten up multiple times, he had to still get up and keep fighting and a lot more was at stake(Considering his entire universe was at stake), compared to the fight with Broly. So Goku wasn't technically pushed to the same extent as he was in the tournament. Having Goku achieve Ultra Instinct would result in them having to bring out characters stronger than Ultra Instinct which is something the series doesn't want to yet. During the T.O.P, it was more or less implied Goku surpassed the Gods with his mastered UI while he went toe to toe with Jiren. It was stated in the narrative of the DBS Broly movie that while Goku was almost as strong as a God, Vegeta is trying to catch up. Hence, they brought an enemy comparable to a God of Destruction. It seems very likely that the series might resume and if it does, it is very possible that we might see Goku possibly attaining this transformation eventually while going up against a very powerful enemy in the series.

Goku didn't go MUI due to the story of Broly Character. It wouldn't make sense for a mastered powerful and strongest form to go toe to toe with a character that has remarkable power. Also rumors say that Goku and Broly will meet again. Broly will have new forms. Goku is going to learn how to tap into the Sayian monkey form like SS4 and power witch Broly has in the movie. Only after Goku masters that form we will see MUI play out again. DBZ/DBS/DBGT are going to have due a lot more tying all the story's into one. DBZ HERO's will appear to have a lot more of crazy new characters and fighting though.

I think the reason Goku failed to become ultra instinct was because he tried to force it to awaken. In all the Dragon Ball episodes when he awakened ultra instinct he did not force it. Ultra instinct was like an "end game" transformation because he is always beat-up the point that he can barely stand before he can activate ultra instinct.
In the Broly movie he was super sayain god and for a second tried to force ultra instinct and he failed and was forced to turn to super sayain blue his 2nd most powerful form besides unmastered ultra instinct.

Is Dragon Ball Heroes Goku Ultra Instinct way stronger than Dragon Ball Super Goku Ultra Instinct?
In the preview for episode 6 of Dragon Ball Heroes we see Goku UI handling Super Saiyan 3 Cumber.

This is the same Goku who fused with Vegeta fought Cumber before. When Goku was fused with Vegeta, they used kaioken times 50 IIRC. And they were fighting Cumber in base form, which is 50x2x4 = 400 times weaker. This means Cumber SSJ3 is (400x50) 20000 times stronger than Vegito Super Saiyan Blue. And this Cumber SSJ3 was being handled by an unfused Goku Ultra Instinct. Now according to Wiss, fusion multiplies the power of the warriors "tens of times". That's at the very least a times 20 multiplier. Assuming this lower bound for the sake of the math, that makes Super Saiyan Blue Goku to be at the very least 20x20000 = 400000 times weaker than Cumber SSJ3. But then Goku Ultra Instinct was handling Cumber SSJ3, so the multiplier from Super Saiyan Blue to Ultra Instinct in Dragon Ball Heroes has to be at the very least 400,000. And it could be much more. If the fusion multiplies by 50, it would be 1,000,000 . If the fusion multiplies by 100, it would be 2,000,000 . Now, this doesnt look at all as the power boost Goku got in Dragon Ball Super from Super Saiyan Blue to Ultra Instinct. Then my question is, is Dragon Ball Heroes Goku Ultra Instinct way stronger than Dragon Ball Super Goku Ultra Instinct?

I think you're reading too much into this.
First, consider that Dragon Ball Heroes is a non-canon promotional anime. The scenarios within aren't necessarily supposed to be consistent, they're just supposed to be cool and promote the game, Dragon Ball Heroes. Because of this, it makes the most sense for Goku to go through all of his forms before gaining the upper hand on Cumber. This includes all of his Super Saiyan forms, as well as Vegito and Ultra Instinct.
As well, consider that Akira Toriyama has never been totally consistent with the exact strength that the Super Saiyan transformations grant to their users, and he has been inconsistent in general with how strong characters are throughout the series. For example, back when DBZ: Battle of Gods was released, Akira Toriyama stated that in terms of power, Super Saiyan God Goku was a 6, Beerus was a 10, and Whis a 15 (source). If this were still true, SSJ Blue Kaioken x20 Goku should absolutely destroy both Beerus and Whis at the same time. Clearly, this was just a rough idea he had, and it was retconned as Dragon Ball Super continued.
To answer your specific question, I would say that it's impossible to judge the strength of Dragon Ball Heroes Goku relative to Dragon Ball Super Goku. Dragon Ball Heroes is not concerned with coherence and consistency as much as it is cool scenarios, and thus, characters will be as strong or weak as the plot needs them to be.

Yes. For one, Dragon Ball Heroes follows events from TOEI anime and Xenoverse timelines, so it is in fact VERY different to canon DBS when it comes to power scaling or even consistency in general. All of the above simply means that Dragon Ball Heroes characters are leagues stronger than anyone in Super. Take for example Mechikabura who was able casually create a Black Hole in his hand that absorbed all possible timelines, which there are widely considered to be infinite of. The same Mechikabura was one-shotted by Trunks in the DBH manga, which happened way before these current events. Compare that to DBS, the best feat is Zeno destroying just 1 single timeline. There's also Fuu absorbing DogiDogi's power, a bird which is similar to TokiToki that controls space-time across all timelines, and then battling Universal Tree Goku, all of these are showing way beyond anything in DBS so far including the manga.
So yes, DBH characters in general are simply much more powerful just by virtue of being a DBH character, as silly as that sounds, but Dragon Ball power scaling is rarely not silly.

Yes dbh Goku is leagues above anyone in dbs. capsule corp Goku (who isn't the same as dbs Goku considering cc Goku knows turles who dbs goku doesnt) fought Xeno goku and gave him a challenge, this already puts his attack potency at multiverse lvl- complex multiverse lvl due to xeno goku managing to fight demigra who was going to destroy infinite timelines. In dbs the strongest feat ever performed was Zeno erasing a timeline, that timeline would contain all 12-18 universes making Zeno low multiversal, until Zeno shows greater feats, he caps at that level, and dbs goku scales nowhere near to Zeno in terms of attack potency and destructive capability meaning base capsule corp goku would be more than enough to wash dbs mui goku. Now im using vs battle wiki tiers, if u want to put Zeno at multiversal that's fine but that still doesn't change the outcome of the fight due to people in heroes scaling higher into multiverse lvl than dbs.

Xeno Goku can be Low-Complex Multiversal, not Complex Multiversal. DBH does not have dimensions beyond 5 or 6. However this isn't a power scaling post

Firstly, the answer to your question is a definite Yes. Dragon ball Heroes Characters are multiple times stronger than characters from any of the canon series. Secondly, The Dragon Ball Heroes Power levels are completely inconsistent and Broken. The strength of the characters are completely adjusted solely for the sake of plot, so I suggest you don't take anything seriously. The reason I say this is for example recentlyWe first see SSJB Goku fight SSJ4 Xen Goku. In the manga, SSJB Goku ends up victorious making him the stronger off the two.We see Base Cumber holding his own against SSJB+Kaioken Vegito(Which is technically 2 SSJB Vegito's).Then we see Goku turning SSJG and attemption to fight Cumber and actually trades a few blows with him which makes no sense.Then we see, SSJ4 Xeno Vegito being strong enough to overpower SSJ3 Cuber who is 400 times stronger than Base Cumber SSJ4 Xeno Vegito should be weaker than SSJB Vegito and SSJB +Kaioken Vegito should be way stronger

In Episode 9 when Goku returns he does not use mastered UI, he fully "Masters" Omen UI apparently and could use that form at will. And when he was attacking it was like he uses the power of MUI when he attacks for a brief second. So that  yea SDBH  UI is stronger

Please elaborate on your answer. As it stands, I'm not sure it provides enough proof to support your claim.

KK doesn't multiply SSJ Blue. KK only multiplies regular ki (base form power) and then adds it to the SSJS whatever form Goku is. KK x20 (baseform) + SSJ + any divine state. Goku's power will only increase 1 or 2% since divine ki is way bigger than regular ki.

Does a Ghoul need to cannibalize to reach SSS level?
Apparently all the Ghouls which are classified as SSS have a kakuja obtained by cannibalization. Does a ghoul need to cannibalize to reach SSS level? is this mentioned in the manga, some OVA or something?

The only 3 ghouls considered as SSS are kakujas (see article for reference). Also, in most cases, power of ghoul is determined by his kagune properties (which can become weapon, full body protective armor, etc), so kakujas clearly have advantage in power over regular ghouls. So, as we don't have any other facts regarding rating assignment, I'd say - yes.

yes, kinda. usually there a gourmet thought right? they eat more than a normal ghoul like rize did.

Welcome to Anime & Manga Stack Exchange. While this might be correct, could you add some sources/references for this, like the specific chapter/episode? Thanks.

Why didn't Bakugo fight Mirio Togata with the other students?
In the anime in the last episode of season 3 all students fight Mirio Togata with the exception of Todoroki and Bakugo. Todoroki is asked if he isnt going to fight by Eraserhead and he says he doesnt have his temporary license and Bakugo just wasnt there. Why didn't Bakugo go with the other students to fight Mirio as training?

Bakugo was still under "house arrest" as punishment for his previous fight with Izuku which is why his only appearance in this episode is collecting everyone's rubbish as part of the punishment.
As stated in the previous episode Izuku was allowed to rejoin classes early by presenting a written apology.

Bakugo got one more day of punishment because he instigated the fight.  They both had to write apologies.

Does Mirio Togata have superhuman speed?
Supposedly, Mirio Togata was able to defeat half of the Class 1A students in less than 6 seconds. How is this possible? His quirk is supposed to be permeation, does he for some reason also have superhuman speed as part of his superhero habilities?

There are two reasons why Mirio won with that level of ease against Class 1-A.
First, he trained his quirk extensively, and has extremely fine control over it. He avoided all long range quirk attacks by letting them pass through him, but solidified at the right moments to deliver powerful punches.
But this alone wouldn't explain how he managed to do that in 6 seconds. The real reason for his "speed" is a side effect of his Permeation quirk, which is explained at the end of the fight.
His quirk allows him to pass through solid objects, but if he releases the quirk while there is overlapped with another solid object, he is randomly catapulted out. This instantaneous repulsion effect is what he takes advantage of to mimic 'teleportation'.
It is not an additional or hybrid quirk, and he still has to angle his body correctly in order to appear where he wants. As Ashido rightly puts it "It's like a video game glitch".
Sources: Chapter 124 of the Manga, and Episode 25, Season 3 of the anime.
Edit:
As raised in the comments, this doesn't fully explain how he was able to 1 hit KO Kirishima, who has hardening, with just normal strength.
While unclear exactly why he is so strong, the wikia does list "Enhanced strength" as one of his abilities. Tamaki mentions that he's been strong since childhood, but that he doesn't know to hold back. Nejire also says his "permeation form" has gotten stronger. And Mirio himself mentions he has trained to counter his weakness (people attempting to attack him when in close combat).
It is also possible he was too fast for Kirishima to react in time. Even assuming his catapulting adds momentum to the punches, it seems unlikely that he'd be able to 1-hit a hardened Kirishima.

yet, he still has to knock hardrock heroes like Kirishima. With regular human force?

Nice catch. While unclear exactly why he is so strong, the wikia does list "Enhanced strength" as one of his abilities. Tamaki mentions that he's been strong since childhood, but that he doesn't know to hold back. Nejire also says his "permeation form" has gotten stronger. And Mirio himself mentions he has trained to counter his weakness (people attempting to attack him when in close combat). Also, it is possible he was too fast for Kirishima to react in time. I doubt he would be able to take Kirishima out in a single punch when hardened.

You might want to add this to the answer too. BTW, one could think may be being catapulted it's what gives an additional boost to his punches, still, if you are catapulted into a rock and you hit them with your hands with human strenght you arent going to do much

Togata was able to defeat Class 1A quickly for the same reason Eraserhead was able to defeat multiple villains quickly. He has trained a lot to effectively use his quirk in physical combat.

Are there classes of Kagune or they are all differents?
I've just watched the first season of Tokyo Ghoul anime, and in one episode the subtitle translation made a note where it said some Ghoul had a Kagune related with speed or something like that, which seemed to imply there were classes of kagunes. With the exception of Hinami who inherited traits from her father and mother, all the kagunes shown in the first season appear to be different. My question then is, are there classes of Kagunes or they are all differents?

There are four different kagune types, which depend on kakuhou position in body:

Ukaku - fast kagune, capable of distant attacks, but ukaku ghouls get tired quickly due to RC cells depletion;
Koukaku - high density kagune, heavy, hence slow, but with high defensive capabilities;
Rinkaku - flexible kagune in form of tentacles, good for close combat offense, but not really sturdy. Its owner also has improved regeneration.
Bikaku - kagune with balanced speed, offensive and defensive capabilities.

Hinami is one of rare exceptions, she is Chimera, having hybrid kagune. This is really rare type of kagune.

"Speed type" is probably a translation of Ukaku (Literally: "Feather-red"). Ukaku is one of the four types of kagunes (Ukaku, Koukaku, Rinkaku and Bikaku).
Each type of kagune is considered to be "stronger" than one type, and "weaker" than one type, e.g., rinkaku is generally best against a koukaku, but it's worst against a bikaku.
You can read more about the types on the wiki.

Are all gold saints supposed to be equally strong?
I've read some comments in internet where they refered to a supposed answer of the creator of Saint Seiya stating that all saints were equally strong. Is this true? This doesnt seem to be what's shown in the series and what fans in general think is saints like Shaka and Saga are usually ranked higher.

Unless there's an interview I'm not aware of, Kurumada never said that.
What he said is that what he really cared about was trying to create them all cool and powerful, but even him cannot say which one is the strongest.
You can check that here.

Just thinking at the manga and anime stories, I can say that Saga has much more power that all the other Gold Saints. I am saying this because he is able to force most of them under his will. He is also able to control a couple of puppies saint while he is still in the Grand Master Hall.
Then he is also able to confront and resist to multiple attacks from some gold saints together.

I agree with part of your arguments, but we have to remember that authority is not a physical force itself ;) but it is like a social force, and, really, it represents more power than the brute force since you can sum all the physical forces of it's followers as his resource.

I.e., it is a different comparison between the whole power of each one in anime/manga and the power in a man-vs-man combat in a normal-temperature-and-pression-condition-isolated room :)

Were the War Hammer Titan and the Cart Titan ever shown in the anime?
I've just watched the Attack on Titan anime series I havent read the manga. In the Attack on Titan wikia they mention the War Hammer Titan and the Cart Titan as part of the 9 titans. I've watched the whole one, two and three seasons of the anime, but I dont remember they been showed in them. Were the War Hammer Titan and the Cart Titan ever shown in the anime or they are supposed to appear later in the story?

Neither the Cart or War Hammer Titans have appeared by the point the anime has currently reached.
The most recent episode at time of writing is roughly equivalent to chapter 60 of the manga while the Cart Titan does not appear until chapter 75 and the War Hammer Titan in chapter 100.

 The anime (currently season 3) is not up to the Return to Shiganshina Arc or Marley Arc, The Cart titan appears in C.74 (Part of RTS Arc), and the warhammer titan appears in Chapter 101 (Marley Arc).

Why doesn't Eren's Founding Titan ability to control other titans work on Rod Reiss' titan?
In Season 3 Episode 9 of Attack on Titan, Eren tries to use his Founding Titan powers to control other titans, on Rod Reiss' titan, but he can't. Why doesn't this work?

I don't think there's a spoiler-free answer to this.
Warning: Spoilers ahead

 You need royal blood to use the Founding Titan's ability, unfortunately Eren is not a royal descendant. When Eren first used this ability it was when he came in contact with the Smiling Titan (how she had royal blood is another spoiler).

I dont understand, what does it mean "being in contact"? Be close to another titan with royal bloodline? How about when he used the hardening skill to save his friends? isnt that another founding titan hability?

Being in contact means physically touching another person (doesn't have to a be titan as far as I know). I don't think the hardening skill is associated to the Founding Titan.

Another thing is that he need to be in contact with a Royal Blood Giant, not a royal blood human.

but at the end of the second season when all those titans went to eat that other titan after he threw a punch into the air, who was he touching? I dont remember much but wasnt he alone?

He punched the smiling titan and briefly came into contact with her, thus activating the coordinate power of the Founding Titan. If you want to know more about the smiling titan you can read the wikia, but I'm warning you, it will contain MAJOR spoilers.

@UsmanRafi That's what I thought, too, but according to wikia, Eren must touch a titan of royal blood to control pure titans.

The reason it worked on the smiling Titan is because she was once dina fritz who was royal blood line which passed it down to Zeke and Eren kills her do to that fact it doesn't work on rod is because he was born of royal blood but didn't hear Eren for he rub his ears off. Therefore Eren has a founding Titan in him which makes him be able to us the means to control titian's for the royal blood line also goes through him since is dad ate Frida reiss and he ate his dad but that's all I got

Could Eraserhead delete all All for One quirks at once?
All for One is this powerful villain, who is almost unstoppable because he has and can use many quirks. Is there any reason, why they never used Eraserhead to stop him by blocking all his quirks? Is this just a missing point in the plot or is there any limit to Eraserhead abilities or any quirk to All for One that makes him inmune to Eraserhead abilities?

I don't see why he couldn't.

How about mutation quirks. Does All for One have any mutation quirk? AFAIK eraserhead can't erase mutation quirks

Aizawa’s ‘erasure’ quirk works by temporarily disrupting/disabling a person’s quirk factor. With this in mind, there are two possibilities:

All For One’s (from now on I’m calling him ‘The Big Boss’ to avoid confusion between his name and quirk) entire arsenal of quirks could become useless if the quirk factor of All For One controls everything.
If The Big Boss got the quirk factors for each quirk (which seems like the more likely scenario in my opinion), it wouldn’t matter if Aizawa ‘erases’ All For One as The Big Boss would still have dozens, maybe even hundreds of other quirks at his disposal and it would turn into a game of ‘how many quirks can you disable before you have to blink’.

Aizawa is a great hero, but he specialises in close range combat against people who can’t use their quirks. If scenario 2 is correct then Aizawa stands no chance against The Big Boss in a 1v1 however he could be quite useful in an assist role if someone like All Might or Endeavour were also fighting him, he could disable certain quirks before The Big Boss could do any serious damage and maybe slow him down somewhat by restraining/distracting him with his scarf.

This is mostly speculation, and incredibly hypothetical. With the evidence given, All For One (A4O) by itself is an activation based or transformation type quirk, and that activation can steal, grant/transfer quirks. However, the quirks that are stolen may or may not be used only when A4O is activated.
Erasure, another "Activation" quirk, can disable the quirk factor of any person caught in range. Thus those with Emitter and Transformation based quirks are disabled, but mutant-type quirks lose their functionality.
As far was we can tell the only time Erasure was used on a person with more than one quirk was on Deku in the skills assessment test (One For All is considered as multi-quirk; the stockpile, and the transfer quirks). However, since Deku only used the "superhuman strength" quirk, we don't know if there were other quirks that have been stockpiled. Also, whether or not a person wielding One For All can use Superhuman Strength + another quirk. This can end in one of two ways.
Conjecture 1: If the root of all quirk based power is rooted in the quirk factor, it is possible for Aizawa to disable A4O and all the stolen quirks  with the Erasure Quirk.
Conjecture 2: If the A4O quirk does not need to be activated to use stolen quirks, AND stolen quirks are separate from the Quirk factor of A4O; if and only if each quirk has its own Quirk Factor and Aizawa can disable only one Quirk factor within one person; then A4O will not be disabled by the Erasure Quirk.

I don't think that Conjecture 1 is possible, just because if it was, Aizawa would have helped All Might defeating A4O and they wouldn't be as concerned as they are!

How about mutation quirks. Does All for One have any mutation quirk? AFAIK eraserhead can't erase mutation quirks – Pablo 12 hours ago

It's not explicitly addressed, but during the police preparation before raiding the League of Evil, they make it very clear that they will possibly encounter All For One. Since UA knows All Might's secret, it's not a stretch to also know about All For One.
Logically speaking, if Aizawa could really steal All For One's quirks, he would be absolutely essential to the mission and there would be no reason not to include him... Unless they know that it would not work.
Based on that, while the explanation is not provided, it seems logical that for some hidden reason or another, UA knows that Aizawa won't be able to steal all of All For One's quirks. My guess is that he would only be able to disable the ability to steal other people's quirks, or maybe just one of his quirks - but not all.

Erasure can erase multiple quirks at once as seen by his ability to shut off the quirks of High End Nomus who have multiple quirks (Ch 268, Boku no Hero Academia manga). The reason Aizawa was not present for the fight against AFO was because he was in a press conference to speak about Bakugou’s kidnapping (Boku no Hero Academia S3E9). They arranged the press conference to distract the villains and if Aizawa was not present during the press conference after having a student from his class kidnapped, it would look bad for UA. If they did not hold the press conference the LoV may not have been so unguarded. For a meta reason it would be convenient for the author but it is explained well in the series. Also they have to account for the possibility that AFO may have a quirk that can render Erasure useless like cloaking or something. This might allow him to steal Erasure which would be devastating for the heroes.

According to the anime all for one is a quirk that can take and use quirks, and give them. It also says that it is a storage quirk so it means all of all for one's quirks are within his all for one quirk. There for Aizawa can erase all for one's all for one quirk, and all of all for one's other quirks with it.

Please include relevant sources/references. Specify specific anime episodes and manga chapters.

I am not sure this is correct but I think it’s because he could erase his quirks but not his  strength. The fact that all for one did not die from all mights final attack means he is  basically invincible. His defense is super strong why do you think his  physical strength  is not as strong. And he was  probably helping the people get as far away as they can. And his quirk has a draw back when he blinks there quirk comes back.

Is Gohan stronger than Vegeta in the DBS manga?
So in the last chapter of the manga,

 Gohan and Kefura knocks each other out. A Kefura which is a fusion combining a legendary super saiyan who was able to overpower Golden Freezer and defeat Aniraza, and a fusion who can turn into super legendary saiyan 2 .

In the other hand, I dont remember seeing much from Vegeta in the manga. Is Gohan stronger than Vegeta in the DBS manga?

Characters have been power scaled pretty differently in the manga and anime. Gohan in the manga is stronger than his anime counterpart. I'm personally finding the recent scaling in the Manga to be pretty absurd. We see Master Roshi dodge punches from Jiren/ a being stronger than a God of Destruction (Note: Even if you consider Roshi to be a better martial artist, someone who wasn't even phased by the Timeskip, who is on guard all the time and dodges attacks from UI Omen Goku, is just absur.d).Nevertheless, to answer your question, Gohan from the manga, is definitely not stronger than Vegeta from the manga. Vegeta in the manga scales up to Mastered Super Saiyan Blue Goku. Toppo stated during his fight with Vegeta in Manga Chapter 36, that Vegeta was relative to Goku in terms of sheer power. Hence, Gohan being stronger than Goku would technically make no sense and since Vegeta is as strong as Goku, I think it is still fair to assume the two of them are on the same level.

But Toppo was wrong, because Goku has Ultra Instinct in the manga and Vegeta doesnt. He might be as strong as Goku without using UI, I suppose. But that's a good point. I forgot Vegeta has mastered super saiyan blue who made Goku able to fight fused Zamasu. Anyway, Kefura has to be stronger than fused Zamasu, since she is the fusion of Kale who is shown to be stronger than Goku Black

@Pablo Toppo wasn't wrong as he mentioned the same before Goku attained UI. Kefla is definitely weaker than the Light of Divine justice Corrupted Zamasu(Fought evenly with Vegito Blue in the manga) and also weaker than Fused Zamasu from the manga as SSJB mastered Goku fights evenly with Fused Zamasu and Gohan definitely is not > Mastered SSJB Goku.

@Pablo Also, the potara fusion seemed to be different in the manga as Vados remarked Kefla was as strong as Kale with Caulifla's fighting skills. This is obviously not the general product of potara fusion as in the case of Vegito, in the Buu saga, was obviously substantially stronger than SSJ3 Goku(Who was substantially stronger than SSJ2 Vegeta) and also, they both possess equal fighting skills with Goku probably having the edge.

Which chapter of the manga does Kirishima unbreakable form appear?
The Boku No Hero Academia wikia states that Kirishima has an unbreakable form, which is seen in the manga. So far in the anime until season 3 episode 20 we havent seen it. Which chapter of the manga does Kirishima unbreakable form appear and it's far of close of what the chapters of the manga the anime are covering?

Kirishima unbreakable form appears in Chapter 133. The anime is currently at chapter 110 and will likely end just before the arc in which this happens.

Did King kill any monster in the webcomic out of fear?
In One Punch Man manga #111 ,
A monster so tense for the fear of being killed by King, unintentionally destroyed his internal organs and died.
Did King kill any monster in the webcomic out of fear like he did in the manga?

There is no chapter 151 in the manga. Latest is Chapter 111, AFAIK: https://en.wikipedia.org/wiki/List_of_One-Punch_Man_chapters

oops 111.......

I'd have to re-read the whole webcomic to be sure, but the only instance I recall seeing of King ending a conflict out of sheer fear was the lizard-like guy that gives up, which is also portrayed in the anime and manga.  But he didn't die, he just surrendered to avoid death. Maybe the wiki has a list of all webcomic chapters he appears in that'd aid in this.

Short version: no, such an event is unique to the manga.
Long version:  I'm going through the webcomic looking for all of his encounters with monsters...

Beginning of Chapter 42: King runs into Shitanobeel, a person who transformed into a lizard-like monster over his obsession with reptiles.  Shitanobeel quickly prostrates himself and surrenders.  According to the commentary of the surrounding people, the monster cries, goes into convulsions, and passes out. In Chapter 100 we learn he's still alive.  Briefly.
Shortly thereafter, he encounters Dushimof, the Machine God, and later the giant bird.  He talks his away out of the first one, but neither monster is too afraid to fight him, at least during the time we see them.  King's internal monologue specifically laments that Dushimof is too strong to be scared away by his reputation alone.
Shortly thereafter, King's internal monologue reveals that there have been 6 prior instances where some (high-power) monster appeared before him, he closed his eyes in fear or ran away, and by the time he looked again the monster was dead.  It is strongly implied in the next chapter that Saitama was responsible for all of them (in a few cases he is manifestly so, as we can recognize the monster or even see him defeating it).  These are the events that led King to be recognized as The Strongest Man On Earth; presumably he had no substantial reputation before then, and it's not clear if the monsters in question ever even noticed him.

We don't see King encounter any other monsters until much later, around chapter 73, though he has several cameo appearances as he plays games or eats hot pot with Saitama.  This is in stuff that hasn't been covered in the anime or manga yet.

 4. Starting in Chapter 73 he faces off against Psykos, Homeless Emperor, Evil Water, and Black Sperm at once.  All of them are very tentative about doing anything and, of course, interpret his every action as those of a supreme combat force.  Even when he runs away a few chapters later.  Psykos says that she knows very little about him, and that most monsters that encounter him simply faint. None of his opponents faint or die here.  But Psykos and Homeless Emperor get attacked by other Heroes, Evil Water does nothing because he senses no violence from King, and Black Sperm is left to face him alone (refusing to help the others because that'd leave him open to King's attack), before he also gets distracted.

King has not had any other encounters with monsters depicted in the webcomic.  So no deaths, but one went into convulsions and fainted, and there's an unreliable and unsourced rumor that many others have fainted as well.

Which S class heroes are left in the Hero Association?

 In the last chapters of the webcomic is shown some Heroes retired and others moved to the Neo Heroes.

Which S class heroes are left in the Hero Association?

Could you please add spoilers to this? The manga and anime are no where near this and most people will likely not be at this point in the story

Sorry, but could you also add the specific chapter of the webcomic? It'd make the readers be more cautious if they know whether they have read until this chapter or not :)

This answer will be spoilers for anyone not mostly caught up to the latest webcomic chapter, of course.  It will be easier to list those who left.

Last warning about them spoilers...

Bang - retired (chapter 110).
Superalloy Darkshine - retired, joined Neo Heroes as a trainer  (chapter 110).
Child Emperor - joined Neo Heroes  (chapter 110)
Metal Bat - joined Neo Heroes (chapter 110)

Honorable mentions: Genos was going to join the Neo Heroes until Saitama rejected the idea of joining them.  We also see two people that HA recruiters were offering S-class positions to if they joined (a sumo wrestler and a leader of a mercenary troupe), but both of them were already set to join the Neo Heroes.  In chapter 107 we learn that several of the Tank Toppers have left the HA (possibly joining the Neo Heroes), including Tank Top Vegetarian (an A-class).
In chapter 110, one of the administrative people with the Neo Heroes, who had previously been with the HA, says they've had many more defections across the rankings and classes of the HA.  But we haven't seen any of them to date.

Given the structural setup of the sequence of events leading up to this point—early in the chapter we have a "wait, they're not the only ones leaving..." from an HA administration person, then it cuts to Metal Bat, Child Emperor, and Darkshine at the Neo Heroes—it is strongly suggested that the above list is currently complete.  There are several other S-class heroes who seem to either be on a short leash or have doubled down on training in the wake of their defeat in the Garou fight, but none of them have clearly left the association or been removed from it to date.

So Genos now has to be at leass S Class rank 11?

Which chapter of the manga does Season 4 of My Hero Academia anime start in?
The trailer of Season 4 of the anime My Hero Academia has been released, and I'm assuming that by knowing in which chapter of the manga Season 3 of the anime ends, you can know which chapter of the manga Season 4 starts.
Which chapter of the manga does Season 4 of My Hero Academia anime start?

According to Mangaupdates and the wikia, Boku no Hero Academia adapted up to Chapter 124 in Season 3. Therefore, Season 4 is expected to adapt the chapters after that, starting in Chapter 125.

Does Mob appear in One Punch Man?
I was reading One Punch Man chapter #100 and in the cover there is a guy who looks like Mob from Mob Psycho 100. Is it him?

Just wanted to let you know that that is not the cover for the 100th chapter but rather for Chapter 65 titled Sisters.
Regardless, those are indeed characters from Mob Psycho 100. Starting from the left, we have Dimple hovering above some people then Mob and Tome (president of Telepathy club).
As a side note, from what I could translate from the description above Mob and Tome, the TV アニメ ... モブ サイコ 100 ...東京 MX... means TV Anime ... Mob Psycho 100 ... Tokyo MX. This chapter might have been released before the start of broadcast of the Mob Psycho 100 anime and the cameos of characters, together with the description, was probably meant as an announcement to the new anime that was to be broadcasted on Tokyo MX.
This does not mean however that Mob appears in OPM or is set in the OPM universe. That is only a cover photo, not an actual scene in the manga story.

If you are talking about the chapter 100th Punch: Light

Mob of Mob Psycho 100 is definitely not there
All the characters in the cover page:

Saitama (inside the gift box)
Genos (Above the gift box)
King (inside the sock/shoe)
Child Emperor (with the robot reindeer)
Fubuki
Tornado
Garou (near the bed)
(forgot the name of the kid always with garou)

EDIT:
If you are talking about that chapter, that is chapter 65: Sisters.
And yes! Mob, Tome and Dimple from Mob Psycho 100 is there, but only in the cover page. It is also stated in the One Punch Man Wiki: Chapter 65 (Sisters)

that's not the image I'm talking about

You've said cover page of chapter 100, that's the cover page

The chapter numbering for the manga is very messed up on a lot of sites, as Murata has frequently released chapters in chunks, which some places have (sometimes) interpreted as each being individual chapters.  A lot of them have been getting corrected to the official numberings, but possibly Pablo was using a site which has not.

Did Genos get more powerful than Metal Knight?
In Season 2 episode 5 of the One Punch Man anime, Metal Knight fires a barrage of missiles against Elder Centipede and the monster is completely unharmed. However in the manga,

 Genos manages to make some damage to Elder Centipede with his incineration cannon, even though Elder Centipede regenerates.

Does this mean Genos got more powerful than Metal Knight?

well.... one is hit it from outside and another one is hit the centipede from inside, so... you know the logic right~

The centipede have a harder skin protect it at outside but inside is it organ only.

Metal Knight calls everything "weapons testing".  He's not actually trying to defeat anything.  As such it's impossible to really tell if any feat we see him display is even remotely close to his "maximum".  This is especially so given that these are always remotely piloted suits, meaning there may be dozens of them, and variations within them, that could in principle be used in concert (think Tony Stark and his fleet of suits in Iron Man 3).

May be he calls everything weapons testing because many times he is unable to make any harm. Gotta think Child Emperor's Brave Giant is much stronger than his drone

Why Levi chose Armin instead of Erwin?
So, in episode 55th of Attack on Titan

 When Levi is about to inject Erwin, he hears him say, "professor, how do you know there isnt people on the other side of the walls". Levi reminds that Kenny Ackerman when dying told him that everybody has to be drunk with something. And then he later says he chose Armin because they pushed Erwin to be a demon.

I dont see the relation among all these situations / thoughts. Why Levi chose Armin instead of Erwin?

This is just how I interpret it based on what I know.
In Chapter 72, when Levi and Erwin are talking about the plan to defeat the Beast Titan,
it was revealed that, to quote from the wiki,

He cared more about discovering the secrets hidden in Eren's basement, and finally proving his father's theories correct, than he did about retaking the lost territory of Wall Maria. His dream of understanding the world was so strong that he confessed to Levi that he considered it more important than the victory of humanity.

Levi was reminded of Kenny Ackerman who, while dying, told him that everybody has to be drunk with something... This is when Levi realizes that what Kenny said applies to Erwin. Erwin was drunk on curiosity to understand the world than to save the people within the walls. If he would choose Erwin, Erwin would prioritize his dreams rather than their goal of saving humanity.
And then he later says he chose Armin because they pushed Erwin to be a demon. Had Erwin's circumstances been different, had his father not been killed and if he was able to pursue his goals of understanding the world without having to worry about being arrested, he would probably have been a researcher or someone other than a soldier. Levi understands that Erwin only wanted to answer the questions he had about the world. It was never really his desire to become a soldier or be handed the position of someone who should save humanity. If he chose Erwin, sure, Erwin's questions would be answered but it would likely doom humanity as Erwin's goal stops at answering his questions and proving his father right. In an episode of the latest season, I seem to recall Levi asking Erwin what happens after they find the truth in the basement, to which Erwin replied 'I don't know'.
Erwin sacrificed many lives for his ambition whereas Armin sacrificed his life with the intent of Eren achieving their ambitions. Armin was willing to give up his life and prioritize humanity's survival so long as Eren, the one he promised to see the sea with, can achieve their dream for the both of them. Erwin, however, was willing to give up the lives of his subordinates in order to achieve his dream, which only is about answering his questions and proving his father right.

My interpretation is that Erwin’s main goal was only to find out the truth of the world, by going to the basement. That his dream ends there. He himself stated that he didn’t know what he would do after he accomplished his dream, and so even if Levi gave him the injection, he wouldn’t have any motivation to continue after visiting the basement. This ties in with Kenny’s last words, which Levi took into consideration and was a huge factor in his decision. Kenny said that “everyone needed to be drunk on something to continue.” In other words, they needed a goal. Erwin was so close to reaching that goal, which was also why he hesitated so much to give up on it. Plus, it was his time to rest
On the other hand, Armin’s dreams stretch much further than Erwin’s. Armin said that the first part of his goal was to see the sea, “let's START by seeing the sea”, showing that even after visiting the basement, he would go on to reach his goal, unlike Erwin. Thus, Levi was looking into the long term, and chose based on who would have the drive and motivation to lead the survey corps the best in the future.

Why didn't Tsukasa kill Senku and his friends in episode 3?
In episode 3, Tsukasa had the chance of killing Senku and his friends, after Senku fired a sort of arrow at him and missed, but he left them alive.
Why didn't Tsukasa kill Senku and his friends in episode 3, when they are confronted, Senku tried to kill him , and Tsukasa clearly has no problem killing humans since he destroyed several humans turned into stone?

Tsukasa didn't kill Senku and his friends because he doesn't know how to revive humans. So otherwise he would be alone.

Why Touma is considered only a level 0 esper when he's clearly so powerful and was able to defeat the most powerful level 5 esper?
Toma has the "imagine breaker" which is regarded by many as a very powerful hability, moreover he was able to defeat the most powerful esper and one of the most powerful magicians, one who was capable of turning into reality what he thought.
Why Toma is considered only a level 0 esper then?

if i recall it's because the Imagine Breaker is considered Magic and something not detectable through science while Espers are a product of science.

In general, it's kinda unclear what the algorithm is for determining someone's level/rank. In some cases, it seems to be purely power-based. In other cases, it also seems to factor in the ability of the user to wield those powers. For example, you can easily argue that Mugino (#4) is stronger than Misaka (#3) from a sheer power standpoint. But Misaka has composure and can "more intelligently" use her powers whereas Mugino is kinda... mentally unstable and just blasts with more emotion than thought.

For whatever reason, Toma Kamijo's Imagine Breaker ability is not considered an esper power, so according to Academy City's ranking system he's a level 0 esper with no known abilities.  It's also not seen as a magic ability so he's not considered to be on the other side of the technology/magic divide.  The true nature of the power hasn't been revealed.  Its origins are unknown and the series hints that even Toma doesn't know what its fully capable of.
Toma's ranking is confirmed through the annual System Scan tests, which corresponds to the mandatory physical exams that Japanese students have to take every year. The real life exams measure things like height and weight, but the System Scan tests measure student's esper abilities and these tests have always shown that Toma is only a level 0 esper.
The series also tries to portray Toma's encounters against powerful level 5 espers as a David versus Goliath situation.  A mere level 0 who has the courage to take on the most powerful level 5 espers in Academy City in order to protect his friends.  Given how powerful his Imagine Breaker ability is, this lacks some credibility, but it doesn't stop Toma claiming this himself as he punches someone in the face.

if Imagine breaker is not an esper ability, why do they consider him an esper then?

@Pablo Anyone who's gone through the Power Curriculum Program, the esper part of the curriculum at Academy City, is considered an esper even if they never demonstrate any esper powers.  Most of the Academy students (60%) are level 0s, so having no powers (or an insignificant power) and being considered an esper is actually fairly common. https://toarumajutsunoindex.fandom.com/wiki/Power_Curriculum_Program

Imagine Breaker affects both esper & magic. What is common with both is that they are the mind manipulating reality, one through 'science' (quantative) and the other through 'magic' (qualitative or symbolic). His power therefore is a reassertion of reality. Touma may have an esper power, but his right hand would naturally nullify it.
At least that is my working theory.


text:
Why are level 0 espers considered espers if they have no powers at all?
Supposedly level 0 espers have no powers at all. Are they any different to humans then? Are they supposed to have latent powers or something?

Level 0s have undergone the Power Curriculum Program, so even if someone ranked at Level 0 doesn't happen to exhibit any observable powers, their brains have still been fundamentally rewired. All espers, including Level 0s, are unable to use magic without suffering severe backlash damage because of incompatibility issues.
But it's not necessarily the case that Level 0s have no power at all. Level 0 is described as follows:

Exceptions aside, cannot be considered completely powerless, but is considered one of the so-called "students that can't keep up at school". Might possess some degree of power, but unable to truly control it.

For instance:

Tsuchimikado Motoharu has a Level 0 Auto-Rebirth ability, which applies a weak membrane over torn blood vessels to stop bleeding. It's a pretty weak ability, all things considered, but it's enough save his life from the backlash damage of using magic.
Akemi has a Level 0 Telepathy ability, and she can levitate a paper cup (barely). At the end of Railgun episode 14, she and her friends remark that their stats have gone up a little, even though their levels haven't changed.
Saten Ruiko has a Level 0 Aero hand ability. This is her System Scan result from Railgun episode 14:

As you can see, it's not all completely zero. There's still some amount of power at Level 0; enough for Saten and her friends to be able to see some improvement, at least.

Which are the five manga series that are based off the Toaru Majutsu no Index franchise?
According to Toaru Kagaku no Accelerator

Toaru Kagaku no Accelerator (とある科学の一方通行アクセラレータ Toaru Kagaku no Ippō Tsūkō?, lit., A Certain Scientific Accelerator) is the fifth manga series that is based off the Toaru Majutsu no Index franchise

Which are them? Aside of Toaru Kagaku no Accelerator and Toaru Kagaku no Railgun?

The list of manga series page on the Toaru wikia may be helpful. Going strictly by chronological order by date of first publication, the manga order would be:

Railgun (Feb 2007)
Index (Apr 2007)
Endymion (Feb 2013)
Index-san (Sep 2013)
Accelerator (Dec 2013)
Heavy (Feb 2015)
Idol-sama (Oct 2015)
Astral Buddy (Apr 2017)
Virtual-On (Dec 2017)

All the Toaru manga series can be divided into several different categories:

Main series: These contain canon storylines. I bolded the main series titles in the list above. The Index manga is an adaptation of the original light novels. Railgun, Accelerator, and Astral Buddy are original storylines written by Kamachi Kazuma.
4-koma series: Fun silly spinoff manga, similar to what Rock Lee's Springtime of Youth is for Naruto or what Haruhi-chan is for Haruhi Suzumiya. This includes Toaru Majutsu no Index-san and Toaru Idol no Accelerator-sama.
Special stories: One-off stories. Usually short, usually for an anniversary event or something like that. Endymion is canon, but I'm not sure about the others.
Anthology manga: Sort of like a doujinshi collection, except it's official. Content is non-canon. Lots of different mangaka come together and contribute a one-shot to the anthology. (This happens with lots of other series, too).

Why is Nezuko stronger than regular demons?
In manga #83 it is mentioned that

 Nezuko's regeneration speed matches that of an upper moon, and later it's mentioned that it surpasses the regeneration speed of one of the upper moons.

Also, Nezuko has shown to be stronger than an average demon before, when she kicked those strong demon balls for example. Why is Nezuko stronger than regular demons, considering she neither has martial art skills, nor consume humans to get stronger?

It was referenced by several demons (starting with three-horned demon with clones), that she seems to be strong due to amount and quality of demon blood she was injected with to be turned into a demon. Other possible reasons were not specified so far.

@lentinant Already mentioned one of the reasons why Nezuko is stronger than most other demons. It's because she was able to survive after taking a large amount of blood from Muzan Kibutsuji.
Muzan Kibutsuji may have tried to kill Nezuko by exploding her after injecting a lot of his blood into her veins. But she was somehow able to survive with that much of Muzan's blood, that's what possibly made her a powerful demon.
In one of the episodes, we see Muzan Kibutsuji frightened of Nezuko and Tanjiro's past relitave when he found the same earrings and scar on the face and ears of Tanjiro.
Apart from that, I would say her father was possibly a Demon Slayer too, maybe he was researching rare herbs or plants that could protect humans from becoming flesh eating Demons. He was maybe able to create a vaccine with which a human can control his/her will after becoming a demon too. He could have injected his family with the vaccine because he knew Muzan Kibutsuji would come after him & his family in future.
There may be some limitations on a vaccine, like how it should be injected before becoming a demon.

maybe because she sleeps a lot and she conquered muzan's blood. according to Urokodaki that nezuko regain her strength by sleeping. other demons gain there strength by eating humans. so as long that she sleeps she gaining more and more power.

 especially now that nezuko conquered the sun :)

Good guess! but her strength comes from the reason the she got injected so much of Muzan's blood and her family blood line is somehow related to the breath of the sun user.

that one too! according to the manga using breath of the sun tech uses your life force so maybe it's like when you use blood art but since they are a demon the fast regeneration takes it away.
and maybe, we will see a better explanation for the origin why muzan(demon's) exist. maybe it will help to better understand demons

Do Metal Bat and Tatsumaki get any closer to Saitama at any point of the story?
In the opening of season 2 of One Punch Man, there is a shot where you see Saitama with his friends (Genos, King, Bang , Fubuki) and also Metal Bat and Tatsumaki. Is there any obvious reason why Metal Bat and Tatsumaki are there? Do Metal Bat and Tatsumaki get any closer to Saitama at any point of the story in the manga?

For Metal Bat, they don't have any significant interactions so I doubt they'd get closer.
For Tatsumaki, I'm not sure if this can be called getting closer but they

fought during the Psychic Sisters Arc

(this is canon as the webcomic is where the manga is based from). Afterwards,

Saitama displayed concern and interest toward Tatsumaki, as he ran after her to see if she would be alright flying home with her injuries...Saitama then asked her why she became a hero if she's trying to cut relationships with people.

At this point, Tatsumaki almost revealed her past to Saitama but didn't. Instead a flashback was shown when she first met Blast, which, to me, reveals Blast's true identity. To quote from the wiki,

She witnessed a man defeating a giant multi-eyed monster. His name is Blast. His appearance has a strong resemblance to Saitama. In fact, Blast said to Tatsumaki that he is a hero for fun, echoing Saitama's words. Blast ends his conversation by telling Tatsumaki that she has to be strong, because not everyone can save her. This motivated Tatsumaki to become a hero, and this is also a reason why she wants to be alone and cut relationships with people.

The manga, which the anime is following, deviates noticeably from the webcomic at the start of the Garou/MA arc. Off-hand I don't recall the manga having any additional interactions between any of these characters, though.

As of now in the manga, neither Metal Bat nor Tatsumaki are closer to Saitama than before. He meets Tatsumaki at the S-class heroes meet in S01E11 of the anime, but beyond that I don't recall any interactions. I think he hasn't even met Metal Bat till now, since he was absent from the meet.

Metal bat, unlikely. The guy barely appears for the next two arcs and has never interacted with Saitama.
Tatsumaki, absolutely. Not gonna spoil much, but something happened and she and Saitama left on good terms. Not exactly friends yet, but close acquaintance.

How does S-Class heroes' power compare to threat levels?
In One Punch Man, there are classes for heroes, and threat levels for monsters/villains. How does S-Class heroes' power compare to threat levels?

This can be answered from the information in the bonus chapter, Threat Level, in Volume 15.
The threat level and hero rank comparison shown in the chapter are:

Wolf Level - needs 3 Class-C heroes or 1 Class-B hero
Tiger Level - needs 5 Class-B heroes or 1 Class-A hero
Demon Level - needs 10 Class-A heroes or 1 Class-S hero

Disaster or threat levels above demon (dragon and god) were never compared but based on the events in the manga, this might require multiple Class-S heroes, depending on the ability or capability of both the monster and the hero facing it.

There are different threat levels decided upon by the Hero Association. The decision on the threat level depends on

factors such as strength, aggressiveness, and the estimated difficulty in defeating [the monster].

It was also noted in the same chapter that

hero ranks are an imperfect representation of combat ability due to inconsistent factors like battleground conditions and monster compatibility.

This class of heroes was originally created to include characters who can defeat Demon level threats on their own. That said, some of the high ranked S class heroes such as Tatsumaki are capable of fighting Dragon level Threats by themselves or with the assistance of other S class heroes. Another good example is Elder Centipede who is a Dragon Level threat and was defeated by Blast, the first ranked S class hero.

Can all Saiyans become a Legendary Super Saiyan?
Legendary Super Saiyan requires one to have consciousness while maintaining the form. What we have seen so far (canon and non-canon) was the berserk state, where the user is simply out of control.
As we know in order to attain Super Saiyan 4 one needs to have consciousness during the Golden Great Ape state. The Great Ape forms have been known for all Saiyans to be a berserk state that can only be triggered when specific conditions have been met. The user is "rewarded" with tremendous power, but no control. This all is extremely similar to Legendary Super Saiyan Berserk. Once the user gets consciousness in the state he/she can then evolve into the next stage, which would be Super Saiyan 4 (for Golden Great Ape) or Legendary Super Saiyan (for Legendary Super Saiyan Berserk).
Since both forms (LSSJ and SSJ4) require the same amount of consciousness and mental fortitude, does this mean that they are basically the same? I found it extremely difficult to find some actual information on the progress of the two being unlocked so therefor this conclusion is purely theoretical.
Assuming they are, all Saiyans are able to become a Super Saiyan 4 with enough training, consciousness etc. Are all Saiyans also able to become a Legendary Super Saiyan or is it purely genetic? From what I've seen so far, the only distinctive features it has, is emitting enormous amounts of ki. We have seen that Saiyans were leaking ki all over the place, so in that sense it should be possible for all Saiyans eventually, or am I completely wrong?

I believe the transformation is purely geneticFirstly, there is no explicit reference in the Canon - Series to Broly's form being referred to as the Legendary Super Saiyan. Broly's transformation is referred to as Full Power Super Saiyan and when Kale uses the similar transformation, Vegeta states that it might be The Saiyan's True Form, which you can see here.
With reference to your point stating that we have seen these transforms only in their Berserker state, that would be incorrect.  This is because we see Kale control her form during her second fight against SSJG Goku alongside SSJ2 Caulifla.Although I cannot state an explicit reason why a regular Saiyan cannot attain this form as there haven't been any official statement released with regard to this, I suppose I could make a reasonable argument indicating why this transformation is genetic and has not something every Saiyan can attain.If we first look at the way Kale attained the transformation. She had no notion as to what a Super Saiyan was. Her anger out of jealousy resulted in her transforming to this level of power which shocked Caulifla and Cabba. Before she transformed. So it clearly doesn't require greater power as Caulifla was stated that be much stronger than her, it doesn't require any specific training as again, Kale was indicated to be inferior to Caulifla in every single way. The only unique way in her transformation compared to Caulifla's, is that she was angry. However, Goku, Vegeta, Cabba & Future Trunks transformed into the regular Super Saiyan forms out of anger. And clearly, their level of angry was much greater than that of Kales. Hence, based on that precendent, the only reason we can argue why Kale attained the form is because of her genetics.While Broly in his Super Saiyan form had yellow hair, Kale in her "Regular" Super Saiyan form had yellow hair with a tinge of green. The form wasn't indicated to be superior to a regular Super Saiyan and it was even referred to as a normal Super Saiyan( As Champa states he couldn't understand why 2 Super Saiyans were struggling against Goku).  Again the only explanation for this points to genetics.Now let us examine the form. Is the form the strongest possible Saiyan transformation? No. While Broly was strong, it wasn't the form that made him strong. He was holding his own against SSJB Goku in his wrath form which more or less was like a powered up Base form(With the power of the Great Ape). Hence, the form made him several times stronger. Just like his Super Saiyan was stronger than Super Saiyan Blue Goku. Kale, on the other hand, was much weaker than Broly in her base which is why her iteration of the form was much weaker than SSJB Goku.Continuing with my point above, this establishes the fact that there is no reason from a Plot perspective why Goku or Vegeta should master this transformation. The Super Saiyan God and Super Saiyan Blue transformations are still Superior. Goku and Vegeta's training with Whis have resulted from them in going towards the route of Ki Control(Which involves hiding and suppressing your level of energy), unlike this form which is the complete opposite. From an aesthetic standpoint, if you look at Broly's & Kale's ki, aura, energy and all their attacks, they all seem to share the same green color as that of the form. Vegeta and Goku's signature attacks would break that pattern if they were to ever tap into the transformationNow let us look at fusions. Fusions tends to share the genetic characteristics of both the combined fighters. When Kefla transformed into SSJ1 and SSJ2, she retained the green hair in both those forms, which could only mean one obvious thing. The trait made its way from Kale's genetic makeup. If it was a unique form, it would've been acknowledged as one, however, it wasn't.Finally, Adding on to my first point, the one common trait that Broly and Kale share is that the two of them had absolutely very little knowledge with regard to transformations and the main trigger in case of the two was just anger. We have seen all the Saiyans display anger and reached powered up states like Vegeta did against Beerus, Goku against Goku Black & Zamasu and attain transformations like the SSJ and SSJ2. At the same time, we have also seen Trunks attain a completely new unique transformation which made him stronger than Kale. That indicates the form isn't the peak or the maximum level of a Super Saiyan. It is only a unique level of power with unique aesthetics which only Broly and Kale can use. With reference to the movie, I do understand Vegeta's hair turns Green and Goku's ki turns Green as well. However, I strongly feel this was done to create some form of contrast between the Saiyans and Broly for fans who are new to the franchise and have less knowledge about the transformations. Or, it could be solely an artistic choice. The reason I strongly feel the same is because, the green hair Vegeta displayed was a transition between Super Saiyan and Super Saiyan God. Vegeta has Never displayed that form a single time in the series and to be fair, it wasn't even indicated as an explicit transformation as it seemed more like a transition shot between SSJ and SSJG. Another interesting theory which some people seem to think is that it was a way to indicate to the fans, the different levels of power of the Super Saiyan forms(The Full Power Super Saiyan(LSSJ) form is > than the Super Saiyan while inferior to the Super Saiyan God). Then again, this is just a theory.

Great explanations! Based on your points I do realize that it can't be genetic/unique. If it was then indeed it wouldn't carry over in a fusion. As for the hair color in the movie, I strongly believe that this has more to do with the color palette than an actual meaning behind it. Yellow + blue = green. Vegeta uses god ki a lot now so I think as muscle memory that some inferred during his transformation which resulted in green for a brief moment. This is purely my opinion and no fact or so at all though. It also might be a hint towards future content. I will wait a bit before accepting this.

You addressed more than one point:
SSJ4 and LSSJ are basically the same?

They've been created by different authors which I doubt they had the same intentions
One requires a tail and the other does not
One was only achieved by one saiyan per universe, the other wasnt achieved by only one

I think there are enough reasons to think they were never intended to be similar. May be in the future Akira Toriyama will borrow ideas from the SSJ4 for the canon universe just as he did with other ideas but I don think they are the same
Are all Saiyans also able to become a Legendary Super Saiyan or is it purely genetic?
This is what I personally think. Since the state is "legendary" and since the original super saiyan was also "legendary" in some sense (Vegeta mentioned the regular super saiyan was the legendary super saiyan in the series, later it was retcon into the legendary super saiyan is the green hair type) they only can be achieved by some saiyans.
Akira Toriyama recently mentioned in an interview that you require an amount of "S-cells" to turn into regular (yellow) super saiyan, so no any saiyan could get it. Since Broly also has the yellow type super saiyan transformation, and the green type seems to be an upgrade of the yellow type, I think they only can be achieved by some saiyans. (this would mean if you can't get the yellow type, you wont get the green type either). And personally (this is my personal belief) I think they hinted in the Dragon Ball Super movie Broly with the green hair Goku and Vegeta got for a couple of seconds, that they also can achieve and might be close to get the legendary super saiyan transformation (but not any saiyan)

But so far no official or canon answer has been given on the matter. We can only infer the authors intentions through what they showed in the anime, manga and what they say in interviews, twitter, etc.

Different authors means indeed most likely different reasons. I forgot about that. LSSJ being achieved by 1 per universe (so far) is a very interesting point, but I don't think that it is a limitation or something similar, but more a coincidence. The other points are really great, I do realize that there is probably no canon answer, but there can be a logical one. Could you also possible link me the interview? Even if it is only in Japanese. I'd love to read it.

https://kotaku.com/akira-toriyama-reveals-the-secret-behind-dragon-balls-s-1820910864 To quote Akira Toriyama "It’s not like anyone can become a Super Saiyan through training and anger. In order to become a Super Saiyan, one’s body must contain something called ‘S-Cells"

"“Most Saiyans have some S-Cells, although not a great quantity," another quote from Akira Toriyama in that link

Anyway, don't believe that they cant change this in the future. They have retconned ideas in the past in Dragon Ball a lot. So even though what he said it's so for now, he and Toei can probably change it if they feel so, even more considering this is just what Akira Toriyama said in an interview, he forgets things from the series a lot, and this concept isnt even explicity mentioned in the series/movies, etc.

Well that was certainly an interesting read. I am really curious about what road they will choose in the future for the series. I am not entirely sure if it raises more questions than answers in my mind, but that might be something for a different day. I would be speculating a bit too much otherwise about the S-Cells, but it definitely is interesting. I hope he won't forget about this. It will give room to some new extra content in the series such as gene manipulation.

Does Overhaul need to touch with his hands to activate his quirk?
Supposedly Overhaul needs to touch an object or body with his hands to activate his quirk. But in episode #14 of the 4th season of the anime, at the begining of the episode he's seen reconstructing his own body without touching anything with his hands. Does Overhaul need to touch with his hands to activate his quirk? Or how does his quirk work?

Yes, he needs his hands to perform his Quirk.
You are probably refering to the part when he makes his arms/feet big with the help of the other bodies that he absorbed. If you watch close, you can see him performing some moves before - like clenching his fists or other hand movement - which indicates that when used on himself, he can touch any part of his body with his hands for the Quirk to activate.

 That is why after the battle both his hands are cuffed and Shigaraki
 cuts off both to prevent him for using his powers ever again

He touched the big guy's body and turned that big guy into the matter. So, since Overhaul did that, he has a matter that he can use to repair himself with. So, he can gather matter by touching someone else's body, but as for himself, he doesn't really need to touch his own body except when he is healing himself or others.

Why Kinro and Ginro are guardians of the entrance of the village if in the world they leave no other humans are supposed to be alive?
Kinro and Ginro are guardians of the entrance of the village "the kingdom of science"  now. When people from Tsukasa empire came to attack, they were the ones supposedly in charge of letting them in. But before they already were guards of the village, when they live in the world where supposedly no other human is alive.
Why Kinro and Ginro are guardians of the entrance of the village if in the world they leave no other humans are supposed to be alive?

When Senku first arrives at the village, they say that outsiders are banned because the only ones out there are people who have been exiled from the village. Which suggests that there are at least a few people who have been kicked out at some point, although it's not clear who they are, when they were exiled, or if they (or their descendants) are still out there somewhere.

While there may not have been (m)any people around, the guards were surely useful for keeping dangerous wild animals out of the area. After all, we know that there are lions in the region from early on in the series.

Manga Spoilers:
We eventually learn that the village is not the only human settlement left.  Many centuries ago, their village was founded by a breakaway group that sailed to japan from the astronaut's original landing site. Soyuz also washed ashore on a boat as a baby. So, the villagers are vaguely aware that other humans might exist.

Was Raditz faster than the speed of light?
In one English dub (there are at least 3 IIRC), Piccolo says Raditz it's faster than the speed of light. But in the spanish dub, he doesnt say so. How about the original japanese dialogue and the manga? Does Piccolo say Raditz it's faster than the speed of light? Was Raditz faster than the speed of light?

Did Tanjiro use the lighting breath?
At some point in the manga,

 Tanjiro reminds a talking with Zenitsu, where Zenitsu tells him that for being fast he has to direct his breathing to his legs, or something like that. And then he uses this and becomes faster.

Does this mean Tanjiro used the lighting breath?

Yes he uses the proper breathing technique of lightning and it seems like you're asking if Tanjiro can use the forms of the breath of the lightning, Breathing technique and the forms of the technique is (2) different things so the answer is No.
Learning the proper breathing of the technique doesn't mean you will be able to wield your sword just like the other breath of the lightning users it requires proper training and talent to achieve such thing because by learning the proper breathing you'd just allowed yourself to pinpoint the parts of your body to enhance and perform the forms of the technique properly.

Which chapter of the manga does Season 1 of Dr Stone anime end in?
At the end of Season 1 of the anime Dr Stone it says season 2 confirmed (at least where I watched it), so if you want to keep following the story after that, you need to know which chapter of the manga the anime ends.
Which chapter of the manga does Season 1 of Dr Stone anime end in?

Weebchan was correct, to save you a few second it ends on middle of 60. So start from there, but starting from 61 like Weebchan said is also correct since there is not anything important in the second half of 60.

Anime ends at exactly ch. 59 so you could just pick it up from Ch. 61, vol. 7

Welcome to A&M, do you have some sources to go with this statement? Also what about chapter 60?

Is there another anime series aside Gundam which created real scale giant robots?
I was taking a look at the amazing real scale Gundam projects in Youtube. They arent real merchandising today but everything makes one think someday in the future they will be extremely expensive merchandising for billionaries or millionaries depending on if they are just statues or the real moving ones

Is there another anime series aside Gundam which created real scale giant robots?

You could count Tetsujin 28-go, or Gigantor as it was known in the west.

This one was erected in Wakamatsu Park, Kobe, after the Great Hanshin Earthquake of 1995. The idea was to rejuvenate the area with tourism.
As far as I know, this is full-scale, at 18m (59ft) tall.

Here it was known as Ironman 28, which is the literal translation of tetsujin to English (tetsu = ron, jin = man) , ironically because here we speak Spanish. BTW, I just realized the name precedes american's Ironman (Tetsujin 28= 1958, american's Ironman = 1963)

The Scopedog from AT Votoms stands about 14 feet tall, so several people have made 1:1 scale models over the years.

Neat! Makes me think someone might have also already made more small-sized robots like GitS Tachikoma 1:1s, since I've seen plans for 1:2s at least.

Real scale mecha from the 80's 6 episode anime OVA of Starship Troopers

What's Ban power level when he gets out of purgatory?
Supposedly purgatory's harsh conditions and Ban regeneration would make him to stay there for long, making him a lot stronger. What's ban power level when he gets out of purgatory?

Ban's power hasn't been calculated after his exit from Purgatory.
However, we can roughly estimate his power level. In the battle against Demon King!Meliodas, Ban manages to hold his own and fight him one-on-one for an extended period of time. On the other hand, Mael (whose power level is greater than 200 000, according to chapter 279) was effortlessly pushed back by Demon King!Meliodas in a previous assault.
We can thus conclude that post-Purgatory!Ban's power level goes far above 200 000.

its around maybe 400'000 and I think that because ban after purgetory ban was a stunning asset to the battle against the demon king/meliodas

Can Ultra Instinct be used on top of other transformations, like Super Saiyan Blue Ultra Instinct?
Ultra Instinct is sometimes refered as a transformation and sometimes as a technique/state. Now apparently there are thousands of fans who believes Ultra Instinct can be used on top of another transformation, just like kaioken can be used on top of Super Saiyan Blue and make Super Saiyan Blue kaioken, they believe you can have a Super Saiyan Blue Ultra Instinct or a Super Saiyan God Ultra Instinct.
Personally I dont believe this is possible, but there are thousands who thinks so and this situation already has consequences in the Dragon Ball fandom, for example there is a videogame mod of Dragon Ball Xenoverse which allows you to use "Goku Ultra Instinct Super Saiyan Blue Kaioken"
http://www.youtube.com/watch?v=lXHuC2d-0-c&t=9m18s

and there are also fan arts made about it like this one,
https://i.ytimg.com/vi/FBGPK6OZsZU/maxresdefault.jpg
Are all these people just wrong or is there any hint/explanation in Dragon Ball Super that states this is possible?

I think it can. from the beginning whis was trying to teach it to goku and vegita while they where training. the power up is because every part of his body is thinking for it self and optimizing and using the strength they have as efficiently as possible while goku can control his overall strength. so it is not a transformation it is a state. whether gokus body can handle this mush energy being channeled through his body as another matter

There is an answer for this in the last manga chapter (#72) and in manga (#73)
(Spoilers)

 Goku uses ultra instinct on top of the super saiyan god transformation in manga #72 and ultra instinct on top of super saiyan blue in manga #73

This is an interesting question, however, as of now I think the answer would be a no, with regard to stacking it up on top of SSJBIn the anime, The UI transformation was indicated to be a massive power multiplier, even a lot stronger than SSJB+Kaioken*20, which is a reason why we see Goku being able to block Jiren's hits despite his god of destruction like power and also overpower high tier characters like toppo without any effort. Also, despite the Self movement ability being a skill, we see Goku undergoing a transformation and he doesn't utilise it naturally like Whis or the other angels. However, it is possible to stack kaioken on top of it as kaioken is a special technique and not really a transformation. Hence goku would be able to utilise Kaioken with the UI transformation assuming his body is capable of handling it.Now  there is a possibility Goku might be able to adapt this transformation into his base form where he is capable of utilising his self-movement ability without undergoing the transformation. Maybe something like the SSJ transformation during the cell arc, where Goku mastered it and managed to stay in it for a prolonged period of time as though he was in his natural stage. Also this can also refer to him absorbing the god form into his base form or him utilising god ki in his base form.Although, this doesn't seem practical as the UI transformation multiplier seems to be significantly higher than SSJB based on Goku's fight with Jiren so I don't see why goku would wan't to stack the skill with SSJB. Maybe utilising kaioken with the UI transformation might increase his power humongously.

Based on some research on Ultra Instinct I'd say yes. However there is no factual data showing that it happened or is about to happen (yet).
Let me explain why it is possible. First of all, what actually is Ultra Instinct? It is a state of the body where it reacts without the brain having to process the thoughts of responding. Making reflexes instant since the muscles respond without the brains having to process it. You can look at it as the muscles being capable of thinking on their own. Now this is simply a state of mind for the muscles (it sounds weird, but it is most accurate way to describe it).
Now powering up (with things such as super saiyan, kaioken or maybe even another form such as Freeza's forms), affects the stamina, ki and power. These 3 are unrelated to the state of the muscles. And we know for a fact they do stack with each other if different techniques are used. For example kaioken+any saiyan form. So if the same "buffs" can stack, why can't different ones?
What the muscles do and what the ki does are 2 seperate things. Muscles need calories (stamina) and input from the brain to act (normally). Energy attacks require ki. Eleminating the input from the brain is what Ultra Instinct does, meaning the ki and stamina remains unaffected. By this logic it is completely possible to have a ki related buff active while having Ultra Instinct active.
My main source about Ultra Instinct is DBS itself and the episodes where it was shown as well as the episode earlier on when Goku and Vegeta were training with Whis and where Whis gave the example about his body being able to avoid the poop when it isn't wearing shoes. It was described as a state where the body can think for its own. Other than that you can find a lot information in the dbs wiki about ultra insinct.

I think at some point Dragon Ball Super writers are going to have to fix this because if Ultra Instinct is only state and not a transformation why Goku gets an aura and grey eyes and other users like Wiss dont get it?

Most likely something else is acting up as well when Goku uses Ultra Instinct, ofcourse this is pure speculation, but maybe he triggers something alongside Ultra Instinct that has an effect on his ki. Otherwise Whis and the others capable of using it would have the same aura at the very least as well. But yeah I agree they have to fix it or explain it as it is currently missleading.

In the anime episode 129 actually for a brief moment Goku is on his SSJform during Ultra Instinct...  Don't know if it's just a mistake or a spoiler but it does happen so the answer is yes

I’d say yes, at least, with Ultra Instinct Omen, because that version doesn’t change the hair. Due to UI Omen being a state and not it’s own transformation it is reasonable to assume that SSJ or Kaioken could be stacked on top of it. Considering that in UI Omen, Goku still thought about his attacks. But in MUI, it was all automatic, so Goku could become a Super Saiyan in UI Omen due to him still having his mind linked with his body.

Please include relevant sources/references.

Yes I think Goku could at least go super saiyan and kaikoen in ultra instinct. Ultra instinct is basically like a tremendous power up in my book because anyone can use it Master Roshi in the Manga has the ability to use it or at least some of his movements use it even Beerus and Whis say those movements look familiar. Goku couldn't go blue or god though in ultra instinct because those transformations put a lot of pressure on his body

Please include relevant sources/information in your answer.

Yes this is possible if u look in the manga Goku stacks (Super Saiyan God)
With ultra instinct so it's possible.
But i don't think he will be using this "transformation" often now what always get's people is that they think ui is a transformation and it's not. It's a technique. There stating in the manga that goku will be using ui as his base form and the silver hair and aura will be a trump card.

Yes ultra instinct is a technique but whis later on in a manga said his ultra instinct(goku)he see ui as a transformation rather then his base as the angles there normal state is ui that’s why goku hasent reach his full potential and yes has kaio ken can be added to ssj or ssjb ultra instinct should do the same but on a god level

Why does the Naruto wikia state there are 18 wielders of the Mangekyo Sharingan, if Itachi told Sasuke he could be the third?
In the Naruto anime, in episode 132, Itachi told Sasuke that if he obtains the Mangekyo Sharingan he would be the third person to get it, but the Naruto wikia gives a list of 18 wielders.
Why does Itachi think there are only 2 users of Mangekyo Sharingan if there are a lot more? Did all of those users got it after Itachi, did Itachi just ignore those users existence, is his Mangekyo Sharingan another type of Mangekyo Sharingan or what? Could it also be a plot hole? Kakashi got his Mangekyo Sharingan when he was young and saw a friend die. And Itachi counts himself and Uchiha Madara as the 2 users, then, why he doesnt count other users as Kakashi and the others listed in the wikia?
Mangekyo Sharingan

Why is this so?

i think this is a legit question because while one could explain that Itachi doesn't see Kakashi as a true wielder, who does Itachi think is the only other person besides him as having the Mangekyo Sharingan (or does he only count his crow)

Itachi saying Sasuke would be the third to awaken the Mangekyō Sharingan would imply he was talking about the Uchiha that are living.
The only living Uchiha in the time of Naruto Shippuden were Itachi Uchiha, Obito Uchiha, and Sasuke Uchiha (the real Madara was later resurrected), although Itachi believed Obito was Madara. In the order of awakening their Mangekyō Sharingan, it would be Obito, Itachi, and Sasuke.
Obito:

Obito Uchiha awakened his Mangekyō Sharingan after the death of Rin Nohara during the Third Shinobi World War; Obito himself only had his right eye at the time, but the event caused his Mangekyō to simultaneously awaken in Kakashi Hatake, who wielded Obito's left eye. (source)

Itachi:

Itachi Uchiha awakened his Mangekyō Sharingan after witnessing the suicide of his best friend, Shisui Uchiha, shortly before the Uchiha Clan Downfall. With his left Mangekyō he can use Tsukuyomi, an extremely powerful genjutsu that distorts the victim's perception of time. (source)

Sasuke: Is believed to have awakened his Mangekyo Sharingan either because of Itachi's death, or because of learning the truth about Itachi.
So, we can conclude that Itachi was saying he would be the third living Uchiha to awaken the Mangekyo Sharingan out of the 3 Uchiha that were currently alive. Counting all the others, Sasuke definetely was not the third. Also note that the Naruto wiki isn't always correct.

Not sure but maybe Itachi was unaware of the rest of the wielders. This might also be a possibility if you think about it

I doubt Itachi didn't know about the rest of the wielders. He knew about Shisui and his Kotoamatsukami, Madara's MS, as well as Izuna. He was also shown Fugaku's MS in a filler.

Why Ymir jaw titan and Galliard jaw titan look so different?
Ymir jaw titan looks rachitic, when Galliard jaw titan looks bulky.
Ymir jaw titan

Galliard jaw titan

I didnt even recognize the jaw titan when I saw it in the last season of the anime. Why is this so? Is there any explanation in the manga or in any sourcebook why Ymir jaw titan and Galliard jaw titan look so different?

Marley nation modifies their titan shifters so they can harden their body. This is mentioned in chapter 95 page 21
That’s why Ymir’s titan form is different from Marcel or Porco. Ymir was an ordinary girl who didn't train in the military like Reiner or Annie.

Galliard was probably injected with hardening ability, similar way Eren was injected with his hardening ability. And like Pablo mentioned, Ymir was very "Raw" titan. She didn't inject any abilities.
Also, two people possessing the same titan power can look very differently - for example, Grisha was super-hairy in his titan form while Eren has "elfen ears", and I don't think there's any specific reason for it.

I believe that it has something to do with the look of the titan holder, for example, Grisha's Attack titan had a beard, while Erens does not. Yamir has a very small jaw while Marcel or Porco has more pronounced jaws than Yamir.

My theory is that she was a pure titan for way too long so her body adapted to her pure titan form which is why her jaw titan looks like enhanced version of her pure titan. The reason I disagree with the hardening theory is because, The ancient jaw titan still had the headpiece and the hardening attachment marley use Is clearly different as is retractable whilst porcos/marcels is not

It may just be inconsistent writing and Isayama didn't delve further into the topic. I think the original Jaw Titan is meant to look like Ymir's, but I still like your theory.

Ymir was a titan before being a jaw titan and after consuming marcel, she gained power of the jaw titan, not the looks

Who is stronger, Yami or Fuegoleon?
My question is simple, I want to know who is the strongest Yami or Fuegoleon and why ?
I know that Yami uses dark magic but is that enough to beat the salamandar of fire

According to the official stats, Yami is physically stronger, but Fuegoleon has better stats overall, more magic and better control of his magic, that aside counting with Salamander.
Yami Yukehiro
Fuegoleon Vermillion

Yami because the darkness will over rule the power of fire as you saw it do to light magic, even with salamander yami can wihstand strong magic attacts while Fuegoleon takes alot of damage from even the likes of that one mermaid lady.
