* POintOfDivergence: Hoo boy...

* AdaptationalHeroism: Dabi, virtue of not joining the League of Villains and working for the seamstress.
* AdaptationalJerkass: Izuku, courtesy of the ForWantOfANail. Downplayed that while he is still kind, he doesn't have the big heart that canon Izuku had. Making him more of a JerkWithAHeartOfGold.

* ForWantOfANail: Hoo boy...
** First off, Izuku calling out the heroes' reluctance early on led to him not taking the path of a hero and finding his way to vigilantism, which got him to meet Kuroda, becoming the Kuroko's successor. And in extension, All Might couldn't get to offer him to succeed as the wielder for "One For All" as a result.
** Izuku taking the path of vigilantism led to the villains discovering Kuroko's identity early which led to [[spoiler:the villains attacking Inko and Kuroda during the sports festival arc later]].
** The field trip arc went far differently with Izuku as Kuroko having to face an enraged Iida with Stain. Then villains attacked them near the end of the arc and the story went off the rails afterwards.
** Due to the above, several villains that joined the League of Villains due to Stain, such as Dabi, didn't join the league at all during the course of ''Organized Protection''.
** Several of them combine when Izuku goes for an internship at Sir Nighteye's office. Sir Nighteye makes disparaging remarks about Izuku's potential as a successor to All Might, and threatens not to let him continue. Unfortunately, a) Izuku in this world is ''not'' enamored with All Might, and in fact thinks that All Might's effect on society is harmful in the long run, b) All Might has not informed Izuku about One For All (nor that All Might plans to make Izuku his successor) so Izuku doesn't have ''any'' idea what Nighteye is talking about, and c) Unlike canon Izuku who wanted to learn the art of prediction, Black Fox Izuku only wanted a way to get back on the streets to deal with pent up feelings but is not so desperate that he'd willingly work with someone who's only going to be total jerk to him, so he just leaves once Nighteye starts getting rude with him.
* HoldingOutForAHero: According to research Izuku did, the laws and cultural mindset that only heroes are allowed to help people have resulted in two thousand people a year dying because everyone stood back and waiting for a pro hero to show up and solve the problem rather than do something about it themselves - in Tokyo. National and global statistics are worse.

* InSpiteOfANail: All Might, after the first story, intends to make Izuku his successor. However, Izuku rejects the offer because he's insulted that after he proved what he could do while quirkless, he's still asked if he wanted a quirk as if his accomplishments weren't good enough to show he didn't need one.

* BadassNormal: Kuroda, and eventually, Izuku.
* BrokenPedestal: Izuku's is broken when All Might tells him he can't be a hero. This is further broken down once his vigilante training starts showing him that All Might is great, yes... but the effect on society he has is long-term detrimental (since everyone is dependent on him, they're looking at a major problem if he ever gets hurt or killed).

* DeadpanSnarker: Kuroda, and what Izuku becomes as the story progresses on.

--> '''Izuku''': In middle school, you kept knocking me down, telling me my dreams were impossible, that I should "jump off the roof and pray for a Quirk in the next life". Ever since we were little, you’ve done nothing but hit me and tell me I’m nothing. So what is it? Are you mad that I won’t take any more of your bullshit?

** What led to the seamstress, a friend of Kuroko's to pull the strings and stop the rest of the villains from attacking Izuku during the course of ''Organized Protection''. She already helped out Kuroko a lot and having a niece herself, she hates the idea of attacking someone else's kid for the sake of agenda or just because. And a whole lot of the villains who are her customers are actually mad at the league of villains for it. With the thug working for her saying this word to word.

* LoopholeAbuse: Izuku being quirkless makes him suffer less charges than he was supposed to have when the heroes found him, as the legal definition for vigilantism had been change from taking the law into one's own hands to using your quirk for heroic purposes without a license, which a quirkless person cannot do by definition.

* RefusalOfTheCall: [[spoiler: When All Might offers to make Izuku his successor, after Izuku had become a successful quirkless vigilante, Izuku is hurt and insulted, and both refuses the offer to take All Might's quirk and tells All Might to leave him alone.]]
