Please put new entries at the bottom of their respective folders, and move Confirmed/Jossed theories to the Confirmed/Jossed folders.
Wild Mass Guessing is for theories about future developments, so all spoilers are unmarked.
- In a close match, Midoriya will lose to Todoroki.
- Confirmed, though Midoriya succeeds in having Todoroki overcome his problem a little.
- Whether he wins or loses, he has already overexerted himself and will most likely have to rest for the remaining of the arc. It would make the arc move way faster instead of dragging it out and losing the readers' interest.
- Confirmed, Midoriya had lost and most of the fights were skipped.
- Confirmed, Stain really likes Midoriya's heroism.
- Her backstory will reveal that she was often picked on for looking like a frog and having a seemingly-useless quirk. Her motivation for signing up for Yuuei Academy was to prove that she wasn't useless.
- This would line up well with her insistence on her classmates referring to her by her first name. She views it as a sign of friendship and she just wants to have friends.
- This will give Deku more reason to sympathize with her, as he used to be bullied for being Quirkless, opening an option for romantic side story, to contrast the lighthearted humor and edgy fight against crime.
- Mostly confirmed. While Tsuyu wasn't bullied, she did have a Friendless Background and her insistence on First-Name Basis comes from I Just Want to Have Friends.
- Confirmed. Knuckleduster, one of the protagonists of VIGILANTES, is Quirkless, although he used to be a pro hero with a Quirk.
- Will probably be jossed, but the idea of Izuku using a shield like Captain America may not be a crazy idea given how effectively he had used his makeshift shield in chapter 26. Besides, it could be helpfully useful until he fully masters his ability.
- Possibility of Midoriya getting equipment as part of his permanent hero-gear has increased given his partnership with Mei Hatsume in the sports festival. Chances are, she would be happy to lend him her inventions, including prototype equipment. Hey, she got someone to test the "babies" before selling them to corporation, and it's free at that!
- Possibility has grown further as Midoriya is now seeking a way to fight without being reliant on One For All in Chapter 44.
- It's a possible stop-gap measure until he can fully use One For All since he's only got about 2-3 more uses of the arm until it's permanently damaged. He'll probably use some armor or mech-arm as support until he doesn't need it anymore.
- Confirmed in chapter 101 to have added mech support for his arms and legs, onto his hero costume.
- Confirmed in a sense, Sir Nighteye's Quirk saw him dying in a year or two. As he's never been wrong before, All Might certainly believes this can happen.
- And it will be called "All For One" to match his "One For All".
- And one of the powers the villain will gain will be Venomous Chainsaw's, forcing Midoriya to face a villain who possesses the same power that nearly killed All Might.
- Viz's official translation revealed that (according to All Might) that Venomous Chainsaw couldn't even get near him.
- Chapter 29 reveals that one student from class B has a Power Copying Quirk. It's not too hard to imagine someone else has a power stealing Quirk.
- "All for One" confirmed in Chapter 57, and not only was the user of "All for One" the one who wounded All Might, but he was also the one who killed All Might's predecessor.
- And one of the powers the villain will gain will be Venomous Chainsaw's, forcing Midoriya to face a villain who possesses the same power that nearly killed All Might.
- Confirmed. And this is NOT a good thing...
- This is based on the "All for One" WMG above. As stated in the series, quirks have limitations and it is possible that a person with the ability to permanently steal quirks from others could have already existed but could either only steal a limited number of quirks or must fulfill difficult conditions to be able to steal any quirk.
- Following the WMG above, it is possible that a "seemingly quirk-less" individual actually possess the ability to steal quirks but only realized about his/her ability after suffering much grief due to discrimination against people without quirks. If such a person discovers the nature of his/her quirk, then it would only be a matter of finding a way to overcome the limitations of the quirk (possibly via technology). This would lead to the "All for One" scenario of quirk-stealing.
- An alternative to the WMG is that "Venomous Chainsaw" is actually a person who somehow managed to steal two separate quirks, "Venom" and "Chainsaw", but cannot steal any more than that and is thus stuck with the two quirks. If that is true, it would not be surprising that the villain would be interested in going "All for One".
- Jossed, they are unrelated.
- And probably that person is also the one that can grant quirk to other person, the same guy that give Nomu his regenerative and super strength quirks.
- Confirmed.
- The Summer Training arc leads into the Hideout Raid arc, which is centered on Bakugo.
- Confirmed! All for One winds up in a heavily guarded police facility while All Might loses the last of his power. Shigaraki steps up as Big Bad, which was Sensei's intention all along.
- Confirmed in chapter 114.
- The reactions will vary from between negative backlash and defensive support.
- As for Class A's response to Midoriya, some of his friends will probably be understanding of the situation.
- On a related note, if the theory that All for One will steal Bakugo's Quirk is true, then this will only exacerbate his disdain for Deku.
- The exacerbate part seems less likely now, as Bakugo is aware of One for All's true nature thanks to Toshinori and Deku, and wants Deku to train his quirk so they can be real rivals, and in his mind, so he can surpass Deku for real. His disdain has also been slowly dying down too.
- As for Class A's response to Midoriya, some of his friends will probably be understanding of the situation.
- Confirmed.
- Given how people are treated based on their quirks (or lack of quirks like Midoriya before he met All Might), it would not be surprising that there would be people who hate quirks in general due to past mistreatment/trauma. The faction does not even need to be composed of quirk-less individuals as people can be mistreated due to possessing the "wrong quirks" like Shinsou.
- Given Endeavor's past actions, it may be possible that Todoroki's elder sibling(s) would be members of such a faction if not a villain faction.
- Or at least one of Todoroki's siblings since it would seem contrived that all three of his siblings just happen to be Quirkless. Possibly Fuyumi since she's the first one we've seen, and she wouldn't look like the type who'd be an antagonist. Alternatively, Todoroki's mother would be in the faction. She would denounce her Quirk because of all the pain it caused her family.
- Confirmed! The villain Overhaul sees Quirks as a disease, and sees his anti-Quirk bullets as being the cure.
- Given Endeavor's past actions, it may be possible that Todoroki's elder sibling(s) would be members of such a faction if not a villain faction.
- Confirmed, the class begins to prepare for the UA Cultural Festival in chapter 169. While it's mentioned to be smaller in scale than in previous years, the other departments are in charge of it.
- Possibly confirmed with Shigaraki in Chapter 69.
- Chapters 235-237 confirm this with Shigaraki. Holy moly...
- Implied to be the case with Eri in Chapter 156 where it's heavily implied she made her own father disappear with her power. Said childhood only got worse from there because she wound up in the Hassaikai's custody because of it.
- Confirmed in Chapter 184. Aizawa doesn't legally adopt Eri, but due to the dangerous nature of her quirk Eri is now under UA's custody instead of being passed off to foster care. Aizawa will be looking after her with the help of Mirio.
- While the most obvious advantage of being empowered by One For All is Super-Strength and being invincible, it was a receptacle for All For One's other powers. Maybe there are residual powers there that All Might hasn't unlocked yet, or that will be unlocked further by Deku.
- Based on the nature of One For All as the original wielder's latent power-transferring quirk combined with a strengthening quirk that his brother forced on him, logically it should continue to merge itself with any other quirks that its wielders have. While All Might and Deku were born Quirkless, Nana Shimura was not (though her original quirk has yet to be revealed) and we know nothing about what quirks the previous 5 inheritors had. So there's up to six other quirks that could've been absorbed into One For All beyond the original body enhancement and transferability aspects.
- Confirmed. Izuku has recently manifested 'Black Whip', one of the previous users' quirks. Said user has also told Izuku that he will receive all six of One for All's stored quirks.
- We know that All-Might and Izuku, at the very least, were Quirkless when they obtained One For All. We're not sure about Nana Shimura, or any of the other One For All bearers up until AFO's brother (who had a Quirk that could be transferred)— they could have had Quirks, and since OFA is a mutation of two different Quirks joining together, it's possible more could have gotten mixed in. This would explain some Quirk-like abilities that All-Might and Izuku have, such as All-Might's muscle form and Izuku's ridiculous pain tolerance.
- Confirmed. One for All has absorbed all six of the previous wielders' Quirks, and Izuku has already manifested one- Black Whip.
Incredibly powerful fire Quirk, burn scars, seems to be narratively linked to Mighty Endeavor and Shoto, we don't know where Toya is... It would fit.
- Going off of this, Toya was said to have a powerful fire Quirk, but a weak constitution, hence why he wasn't Endeavor's successor. Dabi's quirk produces blue flames, similarly how Endeavor pushes his Hellflame to his limits when fighting the Hosu Nomu. So then wouldn't it make sense for the burnt skin to be part of his "weak constitution"? Not to mention Toya left after a "particular accident". Would make sense for after that accident, for Toya to start hating Endeavor and become a villain to spite him.
- As of Chapter 290, confirmed - Dabi is Toya and his turn to villainy was a direct response to Endeavor's abuse.
- It also fits his name, "Dabi." That translates to "Cremation." It's possible that his old self died and was metaphorically cremated. His whole motif also fits bandages, like some undead mummy surviving and holding a grudge.
- The only thing going against this theory is that in the flashback with Shoto's siblings, none of them had completely dark hair. However, one of his brothers (the one whose face the reader didn't see) does have a haircut similar to Dabi's, so it's possible that he dyed it.
- Adding to the theory is that at the end of Chapter 81, Todoroki's expression looks surprised when he and the others appear in front of Dabi.
- In chapter 192, it's stated that something 'happened' to Touya Todoroki (who is the above mentioned sibling with a similar hairstyle).
- In chapter 202, Endeavor mentions in a flashback that he originally intended Touya to be his successor despite his lacking a combination of fire and ice like Shoto's, because Touya's fire was even stronger than Endeavor's own Hellflame. But Toya inherited his mother's "weak constitution" and thus was discarded as a failure. Which fits well with Dabi, who has a very powerful fire quirk (with blue flame, which in real life burns hotter than red or orange) but admits during the Training Camp arc to being physically weak. And his databook stats include 4/5 for power (surprisingly low given how strong his quirk is, which can only be explained by his weak body). By comparison both Endeavor and Shoto have 5/5 for power, reflecting that they have both strong quirks and strong bodies.
- Dabi is also colored with blue eyes, which in the anime are a similar shade to the eye on Todoroki's fire side. Inherited from Endeavor, perhaps?
- Touya has his father's red hair in the anime, so maybe he dyed it black because it reminded him of his abusive dad?
- Confirmed, Dabi IS Endeavor's son, as of Chapter 290. And he did dye it black!
- Confirmed.
- Confirmed as of 290 - Dabi has revealed Endeavor’s abuses to Japan. The repercussions are yet to be seen as of this posting.
- Partially confirmed: there has been a cover-up by the MLA but the government knows at least something due to Hawks having infiltrated the newly-formed PLF.
- His speed is on par with Muscular and Moonfish, who've been confirmed to have escaped.- Characters who've sat out before like Mirio and Best Jeanist returned during the PLF War arc, so it's safe to assume another important character like him could come back. And with Overhaul also escaping...- He's clearly not been forgotten about, as early in the PLF War arc, a meeting with him that was going to involve All Might got delayed.- He's VERY important to the League of Villain's growth as a whole, as some of their more prominent members like Dabi and Toga joined through his ideals.
As for what he's going to do, no clue if he's going to be a minor villain, or an ally to the heroes (albeit begrudgingly). But a full-blown redemption arc would seem ridiculous, as he's got a kill count of 17.
- Partially confirmed.
- Confirmed in Chapter 290. Dabi claims responsibility for sending Starservant and Ending after Endeavor.
- Confirmed in Chapter 297, thanks to Shigaraki's upgrades and his Near-High Ends, All For One, Overhaul, Muscular, Moonfish, and some other villains make their escape.
- Icarus was a guy who grew cocky despite his father's warnings and flew too high, resulting in his wings burning and him falling to his death. Hawks has wings, seems rather arrogant/brash, and ascended incredibly quickly in the hero rankings.
- Hawks is now working with Endeavor who could easily represent the sun, and there's reason to suspect Dabi, another fire user, will be involved in this arc.
- There's also that panel of him flying up with a bright light shining behind him, which others have already noted looks like a Icarus reference.
- On top of it, both he and Endeavor battled a very odd Nomu. It's possible that will be when it happens.
- With the reveal that he's working as a double-agent in the League of Villains, it could be that when this deception is uncovered this will be how they punish him.
- Confirmed, Hawks wings were severely burned by Dabi and while he wasn't rendered basically Quirkless (Thanks to artificial help), he did continue fighting in the final war, where he lost his wings completely when All for One stole his quirk.
- Partially Jossed in Chapter 44. He would not be retiring but he does have faith in the students.
- Completely Jossed, he retired after his battle with All For One, on live television, and he used the last of One For All.
- Partially Jossed, Midoriya lost, and Todoroki used his flame.
- Jossed. Iida got straightened out after his experience with Stain.
- Jossed. Iida is staying a hero.
- Jossed.
- Judging by Chapter 88, this is Jossed.
- Jossed; he survives the battle with AFO.
- Jossed.
- Jossed, her quirk is revealed in chapter 115, as Human Shifting/Shapeshifting via another person's blood.
It's possible that Toga was like Deku and wasn't born with a quirk. So, she makes up for that with crazy reflexes, crazy speed, and just being crazy. It's also why Toga had the most equipment out of the villains we see during the arc. Unlike the others, she doesn't have a quirk to rely on and so was assigned to just gather blood, for whatever reason, instead of joining the attack.
- Jossed. Her backstory shows that she always had her quirk.
- To add to this, she may be forced to give out the location and weaknesses of everyone present to Dabi and the other villains. That is how they found Aizawa-sensei and Bakugo so fast. Her quirk provides her with such information and if she were able to participate in the battle the heroes and students would have had more of an edge. After she gave them the info, Dabi used the Nomu to nearly kill her. However, since her quirk would be incredibly useful on either the villain side or just on a Nomu, Kurogiri chose to take her half-alive when he came to take the villains away.
- Jossed in Chapter 87, she's narrowly avoided the second scenario thanks to the Big Damn Heroes.
Katsuki's stunned face after overhearing Shoto's conversation with Izuku about his past, in this case, would have as much to do with realizing they share the same father as trying to take in the horribleness of said past. And if Endeavor cares as little for Shoto's brothers as he implies to Shoto soon thereafter, then Katsuki may have been one of the sons who'd had to deal with being ignored or the like, which could explain his desperate hatred for those he perceives not as powerful as him "looking down on him" (since not only does he have his quirk, of all people he'd be Endeavor's—unacknowledged—son), as well as his stubborn insistence to be #1 all the time ahead of everyone (for the goal of both possibly being acknowledged and surpassing Endeavor).
- With chapter 39, Shoto's mother saying that "The children...they're more and more like him" could lend to this theory since Katsuki was a self-centric bully as a child, and both Shoto and he have "fire"-like basis to their quirks. When young Shoto looks outside to a group of children playing, with the implication that they're his siblings, the one in the middle has spiky hair like Katsuki's, though his face is hidden.
- From the same chapter, a main flaw to the theory is said possible siblings being nearby. If they really are his siblings, and they all live in the same household, it'd be strange for Shoto and Katsuki not to know each other's names and so on, as seen in earlier chapters, unless they were kept that isolated from each other.
- Jossed three ways to Sunday. Todoroki was not isolated enough from his older siblings that he doesn't know their names. We meet his older sister in the manga. Also, Bakugo doesn't possess Endeavor's eye and hair colors, which are somehow also passed down to the offspring that received such abilities. And we've met Bakugo's father.
- A simple modification to this theory would be that Bakugo's dad is Endeavor's BROTHER instead making them cousins, yet the last name thing is a serious blow to even that theory (unless Bakugo's dad changed his last name somewhere along the lines) and Endeavor never even interacting with Bakugo's mom. All and all, it is impossible the two are related in any shape or form, they look nothing like each other.
- Jossed. The anime started with 13 episodes in its first cour, and it ended with the Unforeseen Simulation Joint arc.
- Jossed. While not explicitly animated (at least not yet), Shoto narrated the incident as it happened in the manga.
- Jossed. His disdain for 'Fake Heroes' happened because he thought the occupation was suffering from "Fundamental Decay" and weren't acting like heroes anymore in his eyes. He tried to become a hero because he admired All Might, but the two never met. We haven't got any indication as to what caused his deformity... but he's screwed up enough in the head that it might be self-inflicted.
- Maybe one of Stains' victims managed to disfigure him before they died?
- If the Illegals spinoff is anything to go by, Stain may have been disfigured during a scuffle with the titular Vigilantes, or else as punishment by Quinn Hachi.
- His nose was broken by Knuckleduster who mocked Stendhal for his lack of resolve. So as a testament of his resolve, Stendhal cut off his nose and discarded the name, becoming Stain instead.
- He knows that Deku was given a Quirk. That would naturally aggravate him if he were to lose his.
- Jossed, Bakugo still has his Quirk after meeting All For One, and is learning some humility without having to lose it.
- At the moment, Jossed. She used what little blood she had from him to turn into him and lead the Ryuku team into helping Midoriya, Mirio, and Night Eye against Overhaul, the implication being she used all of it so the Villain Alliance could get Revenge on Overhaul.
- This will also stop it from becoming a Story-Breaker Power.
- At the moment, Jossed. After defeating Overhaul, her quirk started to Overload and put her in a mini coma. She did wake up, but they're keeping an eye on her for testing and have noticed her horn seems to be shrinking. So, no, she isn't getting rid of her quirk.
- Jossed.
- Jossed, the anime confirms that it doesn't work on humans.
This is probably not true though, as it's looking increasingly likely that Overhaul's ridiculous power is the real deal. But it might not be that strong a Quirk—like with Mirio, he may be using a standard Quirk in an unconventional way to make it appear much stronger than it actually is.
- Jossed. The shot to Compress's arm was a nullifier bullet to keep him from using his quirk on Overhaul. Overhaul's quirk is what destroyed Mr. Compress's arm.
- Obsession with appearance? Similar facial structure? Gifted in stealth(Aoyama sneaking onto Deku's balcony to leave him a message)? Appreciation for classy snack foods? Both concerned about their popularity? Both with a love of theatrics? Somewhat under-powered compared to their peers? Desperate for attention? They're too similar NOT to be related to each other in some manner. It's also a bit telling that Aoyama had a short character study just before Gentle showed up. Almost as if Horikoshi wanted to keep Aoyama fresh in the readers' minds as we were introduced to Gentle and La Brava!
- Jossed, Gentle, being 34, is way too young to be Aoyama's father.
- Nope, Hawks is way too young to be Inasa's father, and he's also an Endeavor fan.
- Midoriya is only pretending to be affected by Shinso's quirk. After being warned not to screw with him, he decided to fake getting caught in his spell to catch him off guard.
- Jossed, Midoriya was affected but he was able to free himself from the Quirk.
- During Uraraka's fight with Bakugo, it'll turn out that Bakugo is against hitting women, which makes the battle difficult for him.
- Jossed in Chapter 35 and 36, Bakugo only held back because he was being cautious against her as his opponent and with good reason too.
- If Midoriya makes it to the final round against Bakugo, he will avenge Uraraka. Todoroki makes it, Bakugo will beat him, prompting Endeavor to seek Bakugo out like in the above theory.
- Jossed. He doesn't make it to the final round.
- Bakugo will talk his way to victory. He will talk Todoroki into rebelling against Endeavor. In his first act of rebellion, Todoroki will forfeit because he knows it would really piss him off.
- Jossed. It's reversed, Bakugo ends up thoroughly pissed off that Todoroki refused to fight him with full power, and he ends up with an unwanted easy victory.
- Jossed as of episode 50 of the anime, Masaru has a different hair color then Endeavor.
- Jossed. We get to see the exact moment Tomura needed a hero the most, and it is perhaps the one moment most pivotal in his turn to villainy.
- Jossed as of the Meta Liberation Army arc. Shigaraki has regained his memories of his childhood as Tenko Shimura, and learned from his sister what their grandmother looked like and that she was a hero. It's probable, however, that he doesn't know the full significance of his relation to her or that she was a user of One For All (if All For One ever even told him about the quirk).
They both have the same birthday, and in someways, Togata is like Red Herring protagonist for Deku, because they operate in a similar space in narrative as 'future #1 hero'. In reality, they take journey's in opposite directions. Midoriya started quirkless and gained OFA, Mirio started with a quirk but ended up quirkless. Internship arc is the first time Togata loses all the hard work he put towards his quirk, and the first time Izuku uses OFA %100 full cowl extensively.
If the narrative continues in these directions for the two- Mirio getting his quirk back would be lampshading for Izuku really giving up/loosing OFA. But this time, If Midoriya tries to give it up, it'll be to someone who has to take it- possibly because the situation requires it, but mostly because, Izuku would have already done all he could with it by then.
Midoriya has to accept that he was, will be, and always has been worthy as a true inheritor of OFA- only then, once he's fully embraced the power as his own does any attempt to pass on OFA narratively make sense. Who the inheritor will be, however, could be anyone (from Tomura to Todoroki).
- Jossed.
All for One has spent a good chunk of his existence making the lives of the users of One for All harder, and killing Nana's family, kidnapping her grandson, then warping the child to hate her successor is right up his alley. He either killed the family himself and altered Tomura's memories to his needs, or gave the quirk to an unsuspecting Tomura to unleash when the time was right.
Eventually, probably near the end of the series, this will be revealed, and Tomura - thrown into a Villainous Breakdown upon learning that his beloved sensei is the reason he is the way he is and still in possession of the quirk erasing bullets he stole from Overhaul - will turn on All for One, Calling the Old Man Out, shooting him with the quirk erasing bullets, and disintegrating him.
- Jossed. We get to see a flashback of Tomura killing his family in gruesome detail.
- Possibly Jossed. We know that both AFO and OFA house the spirits of those whose Quirks have been stolen or passed on respectively, so it is possible AFO was hearing his brother’s spirit.
I think that Endeavor, much like his son did, might think that Midoriya is All Might's illegitimate child due to All For One's comments regarding All Might passing his strength on to someone, and he instead interprets it to mean that Midoriya is All Might's bastard child. After all, he did meet Midoriya and see that Midoriya's Quirk is eerily similar to All Might's, and being a detective, he would probably end up coming to that conclusion.
Building from this, I kind of get the feeling that now that Endeavor isn't able to get what he wants regarding All Might (being Number One on his own merits and instead getting it because All Might was forced to retire after losing One For All), that he's going to end up forcing Todoroki to outdo Midoriya and thus by proxy proving himself better than All Might via their "progeny".
- With 20 people, it's possible. It's very likely that Midoriya, Bakugo, Yaoyorozu and Todoroki get their own teams. With Midoriya's team consisting himself, Uraraka, Iida, Tsuyu and Mineta.
- Entirely likely if the Sports Festival has a team event later on. Which, at that point will define the Five Man Bands.
- Partially Jossed. There was a team event, but the teams themselves were mostly unpredictable such as Iida choosing Todoroki over Midoriya and Midoriya choosing Mei and Tokoyami. Also, the teams were of 2-4 people instead of 5.
- Appears to be jossed as of Chapter 229. Twice, after getting his arm broken after being attacked by Skeptic, realizes he is the real Twice, and starts using his Quirk again to copy himself.
- Jossed.
- Jossed. Destro has survived, albeit crippled, and has handed the Army over to Shigaraki.
- Jossed.
- Jossed.
- Shigiraki and All for One replacing Deku and All Might in the intro
- The intro being a Dark Reprise of a past intro
- Most of Class 1A being excluded, with those present in cameos
- Jossed.
- When his character development has gone full-circle, he will accept "Kacchan" as his hero name the same way Izuku accepted "Deku" as his.
- Unlikely, Kacchan sounds too cute for Bakugo to accept it as a hero name (although he doesn't mind being called Kacchan, he has been shown to prefer more violent names, which unless he starts liking cute stuff more, won't really change.) Deku actually has meaning to it that would apply to heroism (never giving up) while Kacchan is just a nickname.
- Alternately, his official hero name will be Ground Zero, but Deku calls him "Kacchan" in an interview or something, and it will catch on so badly nobody actually calls him Ground Zero.
- This comes from a post I read on Tumblr actually. And it does make sense, Izuku is a Magnetic Hero that his classmates change and found a new peace and hope for the future and the points the post make actually brought some light to what if no one acted right then in several turning points of Izuku's life. And with some fridge brilliance in mind, it goes a long way. Green, Izuku's color, is often associated to traffic lights that gives you a sign that you can now move forward and, in several RPG'fs, healing effects are cast as green, and gives some chance that you can survive more hits to go on with the game. And to go further, in heraldry, green can mean hope and growth.
- Jossed.
- Alternatively, while he does mistreat his son, he does technically believe in being a hero, but has a very elitist, dark interpretation of what being a hero means. This led him to put Todoroki through Training from Hell many would consider child abuse.
- Alternatively, he might really be a stern but still loving father whom his son misunderstands and resents. May have something to do with his yet-to-be-seen mother.
- While he isn't shown to be physically abusive (yet), Chapter 29 reveals that he's condescending enough towards Shoto.
- Jossed, turns out to really be a case of Abusive Parents, including Todoroki's own mother who is the true responsible for his burn scar. While not exactly villainous, Endeavor seems to be very egotistical and has a screwed-up sense of competition, making him very similar to Bakugo. That is not even counting the fact that Todoroki is the fourth of Endeavour's attempts to produce super-powered offspring as stated in chapter 34.
At the end of Chapter 280, Kirishima had successfully administered Yaoyorozu's sedative to Gigantomachia, and while Gigantomachia responded by putting his armor plating over his eyes, the heroes still appeared to have a chance of winning. The next time Gigantomachia is seen is at the end of Chapter 282, after Iida, Uraraka and Tsuyu learn that Gigantomachia broke through the heroes and is going to rampage through anything in his path. It's possible that the reason we didn't see the heroes' defeat is because the traitor did something to interfere at a crucial moment, causing them to lose.
- I say this is Jossed since the sedative FINALLY takes effect in Chapter 293. Even the strongest sedatives don't work right away. Depending on what you're applying the sedative to, how you're applying it, and how big the dose is, all contribute to how long the sedative will take effect and how long it'll hold.
At the same time, we have Mirio Togata, who runs into similar issues since his clothes don't phase with him. His Lemillion costume is made with fibers that have his hair woven into them so they can go with him when he phases through objects.
Hagakure does indeed have a proper hero costume; one woven with her hair in its fibers like Togata, so she can be both clothed and invisible. The visible boots and gloves she wears aren't the only things she wears. They're a deliberate design choice so she can be located out of combat.
- Jossed.
When Izuku was brainwashed by Shinsou during their match, the spirits of the past holders were the ones to move his fingers to snap him out of it. If All For One works the same way in that regard then OFA could theoretically hijack anyone he gave his quirk to.
- Given that we see One for All's origin via its first user's memories and it lines up with what All Might said, I'm gonna call this one jossed. Also, One for All cannot be forcibly taken, so it's useless for that purpose.
...But in addition will show Deku being far more creative than prior cases. With the (as of current) situation as of chapter 157, it's both fairly clear that Night Eye sees Mirio still as the superior between the two, as well as a current 'need' to get him back into fighting capability. And the quickest way Night Eye knows, is to just use One For All on him. In addition, this would fit the current theme going with it, with the characters having the number in their name, Mirio Togata would fit, though in native Japanese instead of Sino.
However, this comes also with some creative use of one for all once again, as Deku instead gives Miro 50% of One for All's power. Before this happens, nobody considers the idea of a 50% transfer, meaning there is in effect both two users of one for all running about. (Which only adds further mass guessing that it will recombine back to 100% if one or the other is made unable to keep going).
The issue with this theory though, is less that of counter-proof, but plot wise escalation. It opens the door to a massive split of power, and more dangerously a return of said power, since by this sort of logic, someone could be given 1% of one for all, then give it back with the 1% and their own quirk, which can just get even more ridiculous if a stockpile similar to All for One is built up and the power is shared back. Toga's disguise quirk becomes far more dangerous as she might steal bits and amounts of One for All, and so on.
- Another issue, Mirio refused to take One for All. After Night Eye died, he tells Deku he won't take One for All as it would just put Deku in Mirio's place. So, unless they really can divide the powers and concretely prove it will work, Mirio won't take it.
- Crimson Riot is described as a Retro Hero by Kirishima and "Classic", the Man among Men by Midnight, when he chooses his hero name Red Riot in homage to him. The wording "Retro" suggests that Crimson Riot is not a hero of the recent past, potentially being a hero from an earlier bygone era, before the current generation like All Might and Endeavor or the generation before them like Nana Shimura or Gran Torino.
- In the few times he's shown he appears to have dark, shadowed or black eyes with glowing irises/pupils a design feature he shares only with All Might.
- He does posses a quirk that appears to harden his hair but that doesn't necessarily preclude him from having One For All.
- In a Meta sense, he seems to have far too much characterization for what otherwise appears to be a throwaway character. Kirishima didn't "need" a real reason for the name Red Riot, and while the his existence provided Kirishima's character with significant background - such as his admiration, fixation on "manliness", and his desire to change his earlier self - the fact that it goes into far more detail on Crimson Riot's fears and regrets on a past mistake that eventually got him labeled as a "Fearless Hero" see far more significant and fleshed out than simply a character created for the purpose of being the rarely mentioned inspiration for another.
- In fact this "Regret of inaction and fear for the life of others over fear for self - even if that fear for self is present" feels almost uniquely All Might-ish/Deku-ish in it's tone.
Maybe the author is just good at exposition...but it feels like there's more here.
- Counterpoint: We currently have seen at least silhouettes of all the previous One for All wielders, and Crimson Riot doesn't fit any of them.
- And this third sibling has/had a Quirk called "All for Nothing". (Theory base on this drawing:
- Maybe it could be a counter to the other two like stopping energy from being transferred (he can take a lunch but none of the impact would happen.
- This is actually a theory I've had for a while— if All for Nothing exists, they're able to take and give Quirks, but not use them. They're a counterpart to One for All (which can be given and used, but not taken) and All for One (which can take and use, but not give— kind of. My reading of it is that AFO can force Quirks upon someone, but not give them.). They're responsible for constructing the Nomu and giving them a wide variety of Quirks. Hell, they may even be the Doctor who Midoriya saw when he was a kid.
- Problem is, Destro doesn't resemble either of the mystery silhouettes. So unless he had a spiky-hair phase, it probably wasn't him. Would make a great fanfic idea though...
- Jossed; the fourth user is the guy with the scarf and the facial scars.
- Seems to be jossed for now: Nana's quirk has been revealed to be Float, on top of Tomura's quirk having been a mutation (just like Eri)... Unless you want to follow the theory it was discreetly put into him by All For One.
- Blackwhip has already been established.
- Nana's Quirk has been established to be 'Float', and to allow levitation.
- A boosting/inspiration quirk, similar to Trumpet's "Incite" or La Brava's "Love." Coupled with OFA's power boost, it will effectively act as a much weaker, temporary, more manageable version of OFA for his allies to use. This ties in with the idea of hero teams over solo heroes that the story seems to be building towards. Bonus points if this is how Uraraka and/or Iida learn of OFA.
- An empathy quirk, boosted by OFA into full telepathy. Midoriya will have to deal with some serious power incontinence and get overwhelmed by people's thoughts when it first manifests, but mastering it will strengthen his connection to the vestiges and make learning from them easier, even if it doesn't make unlocking the bonus quirks themselves happen any faster.
- A quirk that provides some kind of enhanced senses, like radar, super-vision, or a spider-sense. Beyond helping in combat, this could make it easier to locate and respond to crime or danger. Might be the same thing as the telepathy.
- Confirmed! He has Danger Sense, letting him detect danger, but boosted to headache inducing levels.
- A water projection quirk. He will be able to use it very similarly to how he punches the air, but will be able to use it at a higher level without damaging himself since it isn't as closely tied to the force he is exerting. He might also use powerful water jets as a sort of Not Quite Flight to augment his Shoot Style.
- A "joke" quirk, belonging to a user that was chosen more as a emergency option rather than a thought-out choice of succession. One who had to resort to actual physical edges in a fight rather than quirk-based ones due to the weakness of the quirk during their time and lack of creativity in how to use it. Midoriya however, will figure out how even a "joke" can be of used effectively (together with the boost of OFA added to it) and keep it as a "joker" in his deck of powers for emergency situations.
- A monstrous transformation type quirk, for it's original wielder it was just something that only changed them somewhat for a mild power boost but under OFAs influence it becomes more akin to a werewolf transformation. Giving him greater power plus a more bestial appearance but also making him aggressive and animalistic, forcing him to learn how to control these instincts.
- Shinomori Hikage: Fourth Wielder, his family name contains "shi", or "four".
- Banjo Daigoro: Fifth Wielder, his given name contains "go", which sounds like "five".
- Shimura Nana: Seventh Wielder, her given name is a possible pronunciation of "seven".
- Yagi Toshinori: Eighth Wielder, his family name contains "ya", or "eight".
- Midoriya Izuku: Ninth Wielder, his given name contains "ku", a possible pronunciation for "nine".
- First Wielder: His family name is Shigaraki, so it should be his name. One likely option could be Ichika, which is a common Japanese name that contains "ichi" or "one".
- Jossed, his name is revealed to be Yoichi.
- Second Bearer: Nothing is known about him. If it is his given name, a few possibilities could be Kenji or Ryuuji, with "ji" standing for "two".
- Third Bearer: Nothing is known about him. If it is his given name, it could be "Saburou" (where "sabu" would stand for "three").
- Sixth Bearer: His family name is En, so it should be his given name. This one is more difficult, but one possibility could be Rokuro, where "roku" would be "six".
- Midoriya states that all the other torchbearers he could clearly see except for Toshinori who was fuzzy. He then state that 2 others were also fuzzy. The fuzziness could indicate that they are alive like Toshinori.
- Jossed, the two other Torchbearers were the second and the third and stated to have died after passing One for All to their successors. Plus, when they show up at the end of the Paranormal Liberation War Arc, they are completely defined, they just look away for some unknown reason that is later revealed to be that they do not share Deku's views on saving everyone.
- In Chapter 318, the Second User states he has a way to bolster Izuku Midoriya in some way, but his explanation is not revealed to the readers. That quote is repeated when Bakugou finds Midoriya and saves him from Dictator's attack. This could possibly be his quirk, which allows him to think of someone and that someone is able to locate Midoriya's location. It could be called "Beacon", "Locator", or even "Blood Bond". Considering how often the Second and Third users worked together, it would be useful for finding each other.
- The brief power-up will shave years off each recipient's potential lifespan. Not that anyone will mind that since dying at sixty rather than seventy is better than the world coming to an end and dying right now.
- The passed on power drawing directly from One For All's core reserve and making the stockpiling aspect of the Quirk semi-permanently weaker. "Semi" meaning it will take time to once again build to All Might levels. But with all of the assimilated Quirks, his friends power-ups, and Izuku's sheer determination, the sacrifice of his own power will still be enough to win.
- The vestiges of previous users will be weakened and unable to be reached until the Quirk grows in power again.
- Even if Izuku is capable of stalemating or overpowering Shigaraki as he is now, purely physical force is unlikely to be enough to keep Shigaraki down permanently due to his completely absurd levels of durability and regeneration, at least without outright killing him, which Izuku explicitly seeks to avoid in favor of saving Tomura from himself and AFO. Instead, he'll fall back on One For All's most fundamental ability: it can be passed on. Giving away OFA would completely bypass AFO's entire master plan, which revolved around being able to erode the user's willpower enough to steal it in a battle of wills. He seemingly never considered getting the user of OFA to surrender the power through it's own natural means, which implies he needs to specifically *steal* the Quirk in order to control it, and he probably can't steal a Quirk from himself. Instead of AFO assimilating OFA, it will be the other way around, nullifying AFO's ability to bend the wills of Quirks it consumes. Since AFO likely upgraded Shigaraki's body to withstand holding OFA under the expectation of consuming it into All For One, this will likely destabilize Shigaraki's upgrades and the mental fusion ever further.
- Since All Might has an empathic link with Izuku through OFA due to him having been Quirkless upon inheriting OFA, the same would likely be true for Izuku, allowing him a direct link into Tenko/Tomura's emotional state in order to help bring out the Tenko personality while continuing the fight with the embers of OFA. Thanks to seeing Izuku's efforts to save him, not to mention seeing his grandmother Shimura Nana finally coming to his rescue and redeeming her most tragic error, Tenko's faith in heroes will be rekindled and he will begin to fight off AFO's parasitic corruption. The rest of the fight will involve Tomura gradually freeing himself of his rage in a parallel to the Tomura vs Re-Destro finale. Assuming Yagi's potential death before the battle concludes, since his vestige in OFA is still directly linked to him, it might vanish from OFA when the real Yagi perishes, but since much of Shigaraki's rage is honed on All Might and AFO feeds on The Power of Hate, him being in the vestige world when OFA is passed to Tenko might do more harm than good, meaning this gambit might turn of the series's biggest potential tearjerkers into a massive Nice Job Fixing It, Villain! In the aftermath, One For All will either be destroyed in the process or Tenko will return it to Izuku out of gratitude or respect. One of the Rewind Bullets or Eri herself could rewind Tenko back to his pre-Nomuized state, rendering him much easier to safely detain without killing him and erasing All For One forever.
- He would act as an Evil Counterpart for Midoriya. He never had All Might to help motivate him, so he grew envious of superheroes. He would create artificial powers in order to render Quirks obsolete. Basically, he'd be like Syndrome.
- Or, tying in to the previous WMG, he'll somehow acquire "All For One" and go nuts stealing Quirks.
- Given the fact that the manga is partly inspired by Naruto, Midoriya will likely sympathize with a quirk-less villain even if he is forced to stop him at all costs (much like how Naruto sympathized with Gaara due to understanding the pain of being alone and unloved).
- Or he/she will used tactic and technology, becoming an evil version of Batman, which Deku's analytical ability already resemble.
- Alternatively, instead of a Quirkless villain, a Quirkless character may serve as Midoriya's third rival after Bakugo and Todoroki, possibly built around the question What If?, instead of accepting All For One, Midoriya decided to train hard and use tech to become a Quirkless hero. Such a rival would probably dislike Quirk-using heroes and think himself better than anyone who uses a "crutch" like a Quirk, coming off as just like Bakugo if he was the one born Quirkless instead of Midoriya.
- Though it seems unlikely that All For One has been able to get his hands on 20% of the population of earth, which is the percentage of Quirkless people.
- Chapter 233 reveals his quirk is "Gecko" which apparently makes him merely capable of sticking on walls. However, real-life geckos also possess regenerative capabilities, so if Spinner possessed such ability, he may be not aware of it yet.
His first appearance has him as a talking face protruding from a wall and floor, except that would require his lungs and vocal cords be phased, making him unable to speak, and he can hear Midoriya despite his ears being phased into the wall (or he can read lips). Light clearly doesn't pass through him while he's phased, because if that was true phased body parts would be invisible.
- Also, Midoriya and his mother both have super tears.
- Amusingly, the super-tears has actually been confirmed, with Izuku & Inko mentioning that their Ocular Gushers have actually caused property damage.
As for why they appear, maybe it's because Deku's body still isn't quite used to having a quirk? He did go through several years without one, after all. It could also be because he's simply going further than beyond his normal limits.
- Re-Destro seemingly confirms this.
- There are several feats of strength, speed, and durability way beyond what a normal human can survive. Gran Torino and Bakugo’s Quirks have enough force backlash to explain why they can take blows from All Might’s without turning into Ludicrous Gibs. But, without Quirks of this type, injuries like what Aizawa receives facing Nomu 1, Endeavor from Hood, or Best Jeanist from the All for One should have ended in body bags: even Uraraka tanked multiple blows from Bakugo that shattered concrete. The same goes for strength when there’s instances of Nighteye flinging around 5 kg seals like darts, Stain slicing through giant ice pillars in a sword swing, or Endeavor sending a Nomu flying with a punch. And that’s before getting to the near-Flash Step abilities that people like Shigaraki and Toga possess.
- The societal treatment of Quirkless is pretty inconsistent with the number of background characters whose Quirks are totally useless. Plus, there are multiple combat-capable heroes, villains, and students whose Quirks offer a slight or easily replicable effect (at best) in direct fights: Mandalay, Spinner, Bubble Girl, Hatsume. The commonly held belief that there was no way someone Quirkless could become a hero implies that people with Quirks have an intrinsic quality that makes hero status out of reach for those without. The simple nature of most of the earlier Quirks might mean the abilities themselves can’t be enough of a boost.
- Hatsume isn't trying to become a hero. She's trying to become an engineer, which her Quirk would be somewhat useful for. Mandalay's Quirk may not be useful in a dirct fight, but the Pussycats' specialty is search and rescue, where it would be useful.
- One explanation is, so long as a person continues to use their Quirk while training, convincing their body to associate Quirk use with heavy physical activity, the strain may boost the body’s natural boundaries without facing things like muscle restrictions. For someone like Toga or Stain, who have to subdue their victims by direct violence (while also using their Quirk very shortly before or after each of their kills) there would probably be an automatic association between Quirk and physical ability. This implies that someone who uses their Quirk on and off while going through Training from Hell might be able to replicate the influence of backlash-heavy powers, even if they had the power to do something like change colors.
- This might also explain why Midoriya came in last in the Quirk Apprehension Test. Even considering that several of his classmates had Quirks that boosted their physical abilities, there were still people like Kirishima (shown to have started strength training around the same time as Midoriya), Kaminari, and Jiro, all of which would almost definitely have to rely purely on physical ability as well. Midoriya having only used OFA a single time at that point, compared to the hundreds of times of his classmates, may be the reason why he did so much worse despite his year-and-a-half of training and his high ball-throw score.
- The societal treatment of Quirkless is pretty inconsistent with the number of background characters whose Quirks are totally useless. Plus, there are multiple combat-capable heroes, villains, and students whose Quirks offer a slight or easily replicable effect (at best) in direct fights: Mandalay, Spinner, Bubble Girl, Hatsume.

The simple nature of most of the earlier Quirks might mean the abilities themselves can’t be enough of a boost.
- Just like in Steven Universe the future is influenced on what actions are taken and just like Garnet he is able to see the future based on the actions that are going to be taken. His vision about the team being killed by Overhaul was the posibility that would have happened if they didn't fight back, but Overhaul did not know that.
- One: They'd be hunted down and killed for being monsters.
- Two: They'd kill themselves for being monsters or being different, thinking something along the lines that they were cursed.
- Three: They'd get absolutely positively DRUNK on power, doing risky things, gaining the attention of authorities and through concentrated effort be killed. Which would loop back to one because people with quirks would be demonized by the appearance of those who used thier powers poorly.
- Four: They'd self destruct because they wouldn't know to expect biological limitations of their quirks. We know that every quirk has a biological limitation like Tremors causing concusions, fire quirks causing someone to overheat, or sight based quirks causing dry eye, but would first generation quirk users know that? Most likely not, they'd likely experiment or exhaust themselves or accidentally kill themselves using their powers.
- Five: People with subtle or non offensive quirks, hiding their status as quirk users completely to ignore blowback. This means that these people with the lesser quirks are the basis of modern quirks which is why so many of them seem random, silly, or off the wall, they're mutations of very subtle things coming together.
- So, let me present to you part one: "Electrostatic Levitation" also known as "Electrostatic Floating". Everyone of you who had their hair floating up while while using a plastic comb or fought with styrofoam pieces should be familiar with that. That mechanism fits perfectly with the original mechanic of Float, allowing the user to suspend themselves and float in the air. Now, how does that create a perfect connection to Decay?
- Let´s get to part two then, what actually makes atoms "stick" together and form molecules? Electrostatic force. Van der Waals forces and Hydrogen Bonds are electrostatic in nature and bind atoms together into molecules. Now, if you were to shut those forces off, for example by using a power that can manipulate electrostatic forces, the molecules would just fall apart and the matter that they made up would turn into nothing but gas and dust. Which would fit very well with what Decay does.
- Ochaco's Hero mentor at least notices it. So, does Aoyama.
- Uraraka has acknowledged that she has a huge crush on Midoriya, but is trying to ignore because she's focusing 100% of her attention on becoming a hero rather than letting herself be distracted by her personal life. Of course, she has no idea that he's also got a crush on her, so who knows how she'd handle it if that came out.
- Ochaco has Midoriya attention since as early as UA entrance examination, and stay close to him even now. She also has Clingy Jealous Girl quality on her, when Midoriya praised Mei.
- Tied to WMG about the hero-gear above, the Gadgeteer Genius Mei. Hero-gear is custom made to conform with the user, so they will inevitably get close for "measurement and adjustment", then one thing led to another...
- Mei actually does begin taking Midoriya's measurements in the story, in front of Ochaco, leading her to snap in jealousy.
- Tied with WMG about Tsuyu being an outcast, they will get close mostly on term that they can sympathize with one another, both friendliness to each other, and that both are Adorkable. Fans have noticed, and Rule 34 ensued...
- Bakugo would get really angry at Deku that he not only got a girl to like him, but a whole bunch of girls so he would try to ruin the harem by proclaiming that he likes Uraraka and that Deku is a jerk for stealing her from him. Even if he doesn't actually like Ochaco.
- Deku and Melissa's interactions in the movie have a certain air of Ship Tease. Born quirkless, admiring All-Might, comparable heroic spirits, they have a lot in common. Her father even says he can "the future is in front of him" when while she is standing with Midoriya. Sure, he meant in the Passing the Torch sense, but he might be considering something else as well. Ochaco even thought they were on a date. And by all indications, the movie is canon.
- Ochaco is the cute, easy to talk to, happy-go-lucky, girly girl that may seem fragile but is much stronger, tougher and smarter that you would think at first glance. Whereas Jiro is the cold and sharp at first glance but she appears to be much nicer when you manage to get close to her and is hinted to hide a lot of insecurities and may be much more emotional than she lets show. Both come from a middle-class loving family who is encouraging them as much as they can on the hero business. And both seems to have a really close and strong bond with their fathers. Their physical appearances are opposites with Uraraka having nice curves and fair hair and Jiro being less endowed with dark hair.
- Both Midoriya and Kaminari are friendly guys with an important influence on the class. Midoriya is a deconstruction of the chronic hero syndrome. He is kind, shy, all-loving. Many stated that he looks rather plain, and wouldn't expect much from him. Then comes danger and he will show you just how much of a hero he already is. He is also one of the smartest students and will (refreshingly) think things through and come up with a plan more often than not. On the contrary, Kaminari looks confident on the outside with his flirty, cheerful and enthusiastic personality. But on the inside, he not may be not so confident in himself as he almost always starts to freak out whenever danger (or difficulty) shows up. He is not that bright but has better physical aptitudes that Midoriya. Moreover, Midoriya quirk puts his own body in danger while Kaminari's put others (and his mental faculties too). Again, their appearances contrast.
- They also have a bit of Ship Tease in one of the drama CDs, where they attend a festival together.
- Well it's already been established that they've known each other since at least middle school, and they both get along with each other (then again, they get along with pretty much everybody, even Bakugo), so...maybe?
- Unlikely. She's not necessarily loving a shadow nor does she ignore his flaws like his constant muttering, but she's still shown to harbor a massive crush on him despite getting closer to her ideal version of herself. Plus, with this being a shonen series and Uraraka being the main female lead, typical writing for the demographic dictates either the Main Leads remain single, or they get together. Just ask Naruto and Hinata, Ichigo and Orihime, and Ed and Winry.
- Counterpoint: Hinata wasn't the main heroine of Naruto. Sakura was.
- Counter Counterpoint: Sakura wasn't the main heroine. Kishimoto has gone on record as saying that while he had called her the main heroine, he later came to regret saying that since she never truly acted like she was, and that he had intended for Naruto and Hinata to always be the Official Couple. It's also worth noting that "heroine" has different connotations in Japanese media than in Western media, since it usually boils to "Main Love Interest", and that Horikoshi has officially stated Uraraka isn't a "heroine", but one of the main "protagonists". Plus, the blushing comment is outdated since he ''has'' blushed around her in the more recent arcs.
- Counterpoint: Hinata wasn't the main heroine of Naruto. Sakura was.
- Aoyama - Bright Knight
- It's just too obvious. Besides it sound infinity cooler than I can't stop twinkling.
- He changed it to "Can't Stop Twinkling" already.
- It's just too obvious. Besides it sound infinity cooler than I can't stop twinkling.
- Midoriya is still Deku
- Ochaco will keep Uravity
- Ingenium/Ida - Make it Engenium. That way it's a pun.
- 'Ingenium' is already a reference to the Ingenium engine family. The Iidas are an engine-quirk hero family, it fits perfectly without being too on the nose.
- Red Riot still sounds OK in english so we'll keep Kirashima
- Invisible Girl might be copyrighted so let's make Hagakure Unseeable (Her Hero name)
- Considering they kept it in the English Dub, Copyright isn't an issue.
- Shoji - Armee
- Most of these don't need to be changed for several reasons.
- 1. They are all Japanese In-Universe, so changing them to English words would make no sense.
- 2. The Dub already aired the episode they named themselves in so any names they had were still maintained even if they only truly make sense in their native tongue.
- This may strangely be canon, funnily enough. In-universe, the characters had the same Uncanny Valley reactions towards the creepier side of Mutations as we, the viewers had. So it's extremely likely that all that Medium Blending truly is what they look like in-universe.
The reinstated Overwatch took down Talon, however the world was never rid of villains. The members at the time, both old and new, recognized their time as heroes was coming to an end, so they eventually set up hero schools all over the world to teach young heroes with big dreams to follow in their footsteps and make the world a better place. (Hanzo and Genji Shimada founded UA) Thanks to technology, DNA altering and other things, some kids ended up mutating and developing quirks. Overwatch's name faded as time went on, but the schools remained and developed more and more to help kids with quirks.The robots test to get into UA? A nod to the Omnic crisis struggles in the past.
The arts of bending was sadly lost after many centuries and eventually the world may have reached a point when the Avatar was no longer needed or worse, the Avatar cycle ended. However, as time went on, bending abilities remained dormant, but they also started to evolve. Some other elemental abilities emerged, while others may have been watered down. Kirishima and Tetsutetsu's quirk is a legacy of earthbending. Todoroki's ice quirk from his mother is the result of some waterbenders that became ice specialists while his father's quirk may have been something that somehow managed to stay. Bakugo's explosion quirk is likely a firebending legacy as well.
Many seem to have received a quirk tied to a certain element. Even more so, some plants and manmade objects have achieved sentience and quirk abilities. Little do most of the people know, these animals with quirks would evolve. They'd learn more abilities and powers, and expand beyond their quirks in the beginning. Professors grew very invested in researching them, and some quirkless people considered, what about capturing and training them? This, was the beginning of Pokémon.
Considering You Say Run got an updated version for the second season called Jet Set Run, it'd only be appropriate if future seasons also got remixes of the song. This may possibly even show up as early as Season 3, and play when All-Might takes on All For One. Also, Pun.
- It might even be saved for the Final Battle between Midoriya and Shigaraki, :with all the Vestiges of the former One For All users somehow either manifesting in the real world, or fusing with Midoriya to empower him, or something equally symbolic of "One for all and all for one".
It's the reason her special gauntlet, which would have been incredibly useful to Deku, cannot be made anymore; while created for him and with all the best intentions, the government is afraid that its technology may fall in wrong hands and be reverse-engineered to provide villains with an instrument to overcome the limitations of certain types of offensive quirks. You cannot even blame the governments because of what just happened with a tech her father David had conceived to help All Might. The flipside is that, once investigations verify that she had no knowledge of David's actions, much less complicity in them, most of Melissa's inventions will be given back to her, and she may be even offered a position by the government.
In Chapter 137, one of Overhaul's henchmen is buying toys for Eri, and they are based on a Magical Girl team called Pretty Yure 10, a reference to the Pretty Cure franchise. The scene heavily hints that the team is fictional because it's based on a long-running series, but don't get surprised if later, we find out the Pretty Yure team exists as superheroines with quirks, with the explanation that there's an anime series based on them.
