History Fanfic / FlashbackMHA

* PointOfdivergence: Considering the premise of this fic, this shouldn't be a surprise.

** BecomingTheMask: Since Eri reverted back All Might’s body back to its prime, he regains the idealism he once lost and sees to not only defeat the bad guys, but also help those who are in need. The idealism that he partially wore as a mask to keep society’s stability ends up being part of him.
* BigEater: A common occurrence in people with Stockpile Quirks like Rewind and One for All. Rather than relying on some physical catalyst to power their Quirk (such as Bakugou's sweat glands, or Hitoshi Shinsou's voice), Stockpile Quirks have to be charged up independently first with metabolic energy before they can be used. For reference: a post-recovery All Might has, for a "light" lunch, two barbeque bacon double cheeseburgers (with one-pound patties!), four foot-long chili cheese dogs, a basket of cheese fries, a plate of buffalo chicken wings, and an extra-large meat-lover's pizza. Which he washes down with two liters of chocolate protein shake [[AndADietCoke and a pint of whole milk]].
** Mirko is another: her Quirk only gives her an advantage in developing her muscles, that are otherwise natural, and she has to feed them.

* CartoonishSupervillainy: In a conversation with Midnight, All Might notes that the majority of American supervillains are largely harmless, to the point it's noted that Gentle Criminal is more in the mold of the typical American supervillain. The primary motivations to villainy are either a very dramatic form of protesting, or just wanting to fight a superhero so they can gauge their own strength. He observes that this attitude was probably fostered by America having ''much'' more forgiving laws regarding the use of Quirks and lethal force in self defense, so violent criminals tend to get killed quite quickly. He does note that there ''are'' exceptions to this rule, and that any veteran American supervillain prone to habitual violence tends to easily equal if not exceed the worst of any Japanese supervillains.

--> '''Toshinori''': "Sometimes it feels like I can’t go down to the corner store for some milk and oranges without having to deal with three muggings and a lost ''kitten''...”

--> '''Midnight''': So what happened?
--> '''All Might''': (''shrugs'') Eighteen muggings, nine car accidents, seven robberies, six sexual assaults as well as the obligatory lost pets... and I had to break up a brawl between a couple guys with Kaiju quirks in Nara who were fighting over a girl. (...) Thankfully, there were no fatalities, but there were a couple close calls.
--> She nodded stiffly. If this was the workload of the Number One... well... any Pro who claimed that they didn’t want to be number one was either lying to you or lying to themselves. But hearing this, this wonderful, heroic, self-sacrificing man... he was welcome to it.

-->He called it an "All American On the Go Super Breakfast". Izuku called it a belly busting monster. A giant sandwich made out of ham, bacon, sausage, some ungodly substance he identified as 'scrapple'[[note]]essentially fried pork-scraps meatloaf[[/note]], and eggs... and fried and served between two full sized pancakes that had been drizzled with maple syrup as if it were a sandwich sauce. With a side of fried potatoes with ketchup.

--> If the problem was the villains then they wouldn't be [[TeethClenchedTeamwork forced to work with the villains]]. Logical, innit?
* DidIJustSayThatOutLoud?: Izuku has one of his [[MotorMouth mutter storms]] at the entrance to UA, where he tries to quell his anxiety about the Entrance Exam by repeating what All Might told him earlier. It's only when Uraraka thanks him that he realizes he said all of that out loud to a small crowd surrounding him. Fortunately, they interpret it positively. See DareToBeBadass above.
* DiesDifferentlyInAdaptation: [[spoiler: The Sand Hero, Snatch. In canon he is killed by the League of Villains, during the finale of the Shie Hassakai arc. Here, he dies months earlier, as part of Number 6's ISurrenderSuckers ploy.]]
* DirtyHarriet: Midnight specializes in breaking up prostitution, slaver, and drug rings, often by letting herself be taken in as "product" to info-gather and disrupt from the inside. Sir Nighteye at least is in genuine awe of her willingness to lay her dignity and physical integrity so readily on the line.

* DrivenToVillainy: Saiko Intelli was branded a villain by the Hero Commission in the BadFuture for daring to criticize flaws in hero society, calling her no different than Stain and the MLA, even though her criticisms were more tactless and unintentionally [[InsufferableGenius condescending]] than violent and she intended them to be helpful. Between the Commission, negative public reactions, Seiai Academy poorly preparing her to face [[CantTakeCriticism rejection of her ideas]] and enabling her bad habits, she ended up becoming "Solomia", a Moriarty-style mastermind. Becomes HarsherInHindsight, when canon itself later reveals just what the Commission has been willing to stoop to, in times past, in order to stay in power.

** All For One being one of LaResistance's most dedicated fighter in the BadFuture falls under this. Eri even refers to him as one of humanity's most stalwart defenders.

* TheFatalist: Sir Nighteye was a firm believer in fate, even if that fate was a bad one, as per canon. However, upon learning that his quirk literally can't perceive [[ImmuneToFate Eri]], he is starting to believe that the future actually can be changed.

* ForWantOfANail: Considering the premise of this fic, this shouldn’t be a surprise.
** Since All Might’s no longer running on a timer, not only is he in his peak, but also able to go out more. He started to rekindle the old bonds that he pushed away because of his job, willing to take time for himself as Toshinori instead of just being neck-deep in crime all day.
** Because Izuku didn’t receive One For All from All Might, he begins to acknowledge earlier on that he can’t just be his carbon copy and have to be original himself. In canon, Izuku more or less tried to copy All Might until his arms have been broken multiple times and it wasn’t until a diagnosis did he decide to switch up his fighting style.

* GenreBlind: All Might is ''not'' happy that he completely failed to miss the most obvious clue All For One was still alive.
--> Toshinori’s jaw gritted as he thought back to his greatest failure. Damn it Toshinori, doesn’t matter if your guts are decorating half the goddamned landscape, ''the Joker isn’t dead if you don’t have a body!''

* HiddenInPlainSight: How All Might and Izuku cover up how Izuku now has super-strength and speed when he was diagnosed as Quirkless a decade previously: it takes time for a stockpile Quirk to gather enough energy to do anything noticeable, and at the time of his original diagnosis there ''hadn't been'' time. How would anyone have been able to tell that Izuku had a Quirk, when at that level of charge it would have made him slightly more energetic than he should have been at age four?

* LikeAnOldMarriedCouple: PlayedWith and nearly an InvertedTrope; Tenya's parents literally are a middle-aged long-term marriage, but are perfectly frank that they only hooked up for [[DarwinistDesire reasons of Quirk synergy]] and treat each other as mixture of [[FriendsWithBenefits sex-buddy roommate]] and [[VitriolicBestBuds coworker with a barely tolerable personality]]. Tenya for his part is deeply ashamed and developing a complex over their flaunting of their lack of genuine romance, and is irritated by their incessant verbal slapfights.

* MundaneUtility: Eri has cajoled Midnight into joining her giant chocolate binges, on the promise of rewinding her body to before she she ate any and to avoid fattening.

--> Damn it Toshinori, doesn't matter if your guts are decorating half the goddamned landscape, ''the {{Joker|Immunity}} isn't dead if you don't have a body!''
* NeverGetsDrunk: Due to the nature of One For All, even without activating it All Might can drink three men under the table and still keep going. Activated, he is practically immune to most conventional toxins, as his body can burn them out of his system before they can really begin taking effect. It probably doesn't hurt that he's a very large male, two factors which are known to lessen the effects of alcohol.

** Thanks to her quirk, Eri can inflict this on other people. While she jokes that it's so that people like Midnight can be younger longer, in reality she wants to make sure that some of their best fighters are either at their peak longer or don't die of old age (as Nedzu did, before the invasion).

*** Due to his preparations for the oncoming alien invasion, All Might starts making a bunch of surprise moves which draw a lot of attention for those more familiar with him, and wonder what is going on. When he pulls the ScrewTheRulesIHaveConnections to get David Shields to Japan, his old adoptive brother/sidekick notes he ''never'' does that, and understands that whatever is happening, it is serious. Deadly serious.

** One of Eri's ongoing struggles is with this – she's unsure if she's a little girl who had a whole person's life dumped into her head, or a 27-year-old who's taken over a young girl. In practice she's splitting the difference and claiming she's fourteen, so that she'll be in Izuku's class.

** Mirko hates the idea of doing a sponsorship or public relations appearance, and has resolved to fund herself solely through the bounties on the crimes she foils. It barely covers her Agency expenses, and said agency consists of two bargain-bin lawyers on retainer, a used Winnebago, and a Secretary that does all her paperwork and chauffeurs her van.
** Mount Lady regularly causes property destruction that ranges from the tens of thousands to the millions in damage-costs. The Hero Public Safety Committee covers the bulk of the expense, but she's still in the red and only getting deeper, no matter how much time and energy she's forced to put into "fund-raising events".
* PhonyDegree: Night courses to let people who didn't attend a dedicated hero school qualify to take a hero licensing exam range from quality establishments to fly-by-night con jobs. Mount Lady went to one of the better ones, but it's still noted that the course material was more on the legal and theoretical portion of the job and light on the practical (assuming that anyone seeking to be a hero at that stage in life has already trained their Quirk on their own time), which is a problem for someone like her who has a Quirk that can cause more problems than it solves if not fully mastered, and never had the resources to train in its use.
* PlayingToTheFetishes: Mount Lady does so in-universe. The author takes as canon her segments in ''My Hero Academia: Smash!!'', where Yu once accidentally stepped on a man while doing hero work and amassed an enormous cult following of foot and crushing fetishists, who her manager pressures her to cater to with weekly "$50 to step on you" events to stay [[HeroInsurance ahead of her property damage payouts.]] [[FanDisservice Yu is disgusted by the creeps and her self-esteem has taken repeated heavy blows from her constantly having to all but prostitute herself.]]

--> [[spoiler: He turned one-hundred and eighty degrees on his heel and walked right back into his room.\\

** Mount Lady, in the BadFuture, lost her job due to the rising costs of damage from her Quirk going out of control at times. Eri gives her some advice, and in this timeline she'll be taking extra steps to prevent that from happening, and All Might has offered her the use of UA facilities to help her fully master her Quirk.

* SexIsGood: Midnight in this fic eventually explains that, beyond the self-indulgent exhibitionism of her teen self, she maintains her over-the-top sex icon persona because she specializes in [[DirtyHarriet combating sex-trafficking]], and wants to be a symbol to her rescuees that sex itself is still a positive and fun aspect of life, and they can reclaim ownership of their bodies. It's why she sees her harvesting by Dupe for rape drugs in the past timeline as a worse violation of her self than merely being a SexSlave.

** The author's disdain for Midnight's canonical fate of being killed off in canon lead to her instead having her DeathFakedForYou by a sleazy supervillain who kept her on life-support and pumped full of Quirk-boosting drugs so he could create dead clones of her whose bodies he could then harvest for her soporific pheromones to sell as DateRape drugs.
** The denouncement of Magne as simply a bad person who happens to be trans and who likes to throw her status as trans around as a weak excuse for her villainy, even being called "an unrepentant psychopath using her identity as a transwoman to provide a freudian excuse to kill and steal without remorse" in chapter 30, seems almost tailor made to attack the fans of Magne who tout her as a TragicVillain because of her transwoman status.

* ThreeLinesSomeWaiting: The three primary focus characters are All Might, Eri, and Izuku. Izuku gets the least amount of focus, because as an unlicensed and untrained UA enrollee, he doesn't really have the knowledge, skills, or agency to actually ''do'' anything yet.

** When All Might has a chance to talk to the Crawler about how he flunked getting into a hero school and is told he was failed because he was late for the exam... ''because he was saving somebody in danger''... All Might is appalled, and not surprised in the least to find out the academy in question was one of the so called “Hero Public Service Academies”.

** Tenya reveals to Izuku that his father's Quirk is literally fueled by juice, and this element was hybridized into his son's Quirks, so both Tenya and his brother literally are powered by juice, obligating them to consume it on the regular to fuel their Quirks. A surprised Izuku privately notes that this explains why Tenya's family have so many sponsorship deals with juice companies.
* TraumaCongaLine: Mount Lady was summarily barred from almost every single high school she applied to because no one would trust her to control her [[SizeShifter Quirk]] well enough to not destroy the place. When taking the entrance exam for UA, she stressed out during the written test and [[PowerIncontinence uncontrollably embiggened]], [[WardrobeMalfunction destroying her clothes]] and injuring several other students. She was so humiliated by the event she abandoned UA altogether, and [[PastExperienceNightmare still has nightmares of that humiliating day years later.]] Her high school experience in an agricultural school was filled with people wanting to exploit her Quirk for livestock work or arrange Quirk Marriages for her. Her studies at a Hero Night School [[labelnote:*]](in a course that All Might suspects may have been subpar ''despite'' her researching their credentials)[[/labelnote]] meant she never received proper training for her Quirk, leading to her [[CuteClumsyGirl trail of accidental destruction]], and her ever-growing debt. This led to her doing fetish events for quick payouts to stay ahead of payments[[labelnote:*]](with the implication that her manager may in some way be messing with her finances)[[/labelnote]]. By chapter 30, Mount Lady is an overworked, self-loathing wreck wondering if the humiliations she's suffered in trying to be a hero are worth it, and when All Might stumbles across one of her "fan meets", she runs crying into the locker-room and [[DrivenToSuicide seriously contemplates committing suicide]], before All Might comes in and swears to help her get out of her horrible situation. This gives her a chance to avoid what Eri remembered of her fate from the original timeline, which involved losing her license due to the mounting costs of Quirk-related accidents, then becoming an alcoholic before vanishing from the public eye before the invasion hit.

* UnskilledButStrong: A weird variant with All for One; when he steals other people's Quirks, he gets them at their base strength without any power increases or evolutions that the original user might have unlocked through training. He absolutely ''could'' grind them back up to strength, but he'd much rather have a huge Quirk pool where he can mix-and-match various powers from to form an effective CombinationAttack that is as strong as he wants.

--> '''All Might:''' "I know the feeling, ''I really do''. Sometimes it feels like I can't go down to the corner store for some milk and oranges without having to deal with three muggings and a ''lost kitten''..."
* WhatHappenedToTheMouse: Oddly, Eri has yet to mention Tomura Shigaraki, with regards to her [[SetRightWhatOnceWentWrong future memories]]. Whether that has anything to do with [[GrandTheftMe him being taken over]] by All For One in canon is as yet unknown.

* DrivenToVillainy: Saiko Intelli was branded a villain by the Hero Commission in the BadFuture for daring to criticize flaws in hero society, calling her no different than Stain and the MLA, even though her criticisms were more tactless and unintentionally [[InsufferableGenius condescending]] than violent and she intended them to be helpful. Between the Commission, negative public reactions, Seiai Academy poorly preparing her to face [[CantTakeCriticism rejection of her ideas]] and enabling her bad habits, she ended up becoming "Solomina", a Moriarty-style mastermind. Becomes HarsherInHindsight, when canon itself later reveals just what the Commission has been willing to stoop to, in times past, in order to stay in power.

--> Toshinori: "Sometimes it feels like I can’t go down to the corner store for some milk and oranges without having to deal with three muggings and a lost ''kitten''...”

--> “So what happened?” she asked.
--> He shrugged, “Eighteen muggings, nine car accidents, seven robberies, six sexual assaults as well as the obligatory lost pets... and I had to break up a brawl between a couple guys with Kaiju quirks in Nara who were fighting over a girl...”
--> Her eyes almost bulged. No wonder he needed a beer. And that’s not even counting the mountains of paperwork he would have to file for all of that.
--> “Thankfully there were no fatalities,” he continued, “But there were a couple close calls.”

* DareToBeBadass: Izuku unintentionally inspires this during the entrance exam, while muttering to himself about the advice All Might gave him. As a result, so many participants – now more concerned with actually acting like heroes, rather than simply passing the exam – end up racking up massive amounts of Rescue Points, that the faculty has to devise a ''third'' point scoring system and commission a ''third'' Hero Course class in order to keep up!

The moment before Izuku is set to recieve One for All, Eri suddenly arrives in a panic and with a desperate need to pass off her own version of One for All before she explodes.

* DrivenToVillainy: Saiko Intelli was branded a villain by the Hero Commission in the BadFuture for daring to criticize flaws in hero society, calling her no different than Stain and the MLA, even though her criticisms were more tactless and unintentionally [[InsufferableGenius condescending]] than violent and she intended them to be helpful. Between the Commission, negative public reactions, Seiai Academy poorly preparing her to face [[CantTakeCriticism rejection of her ideas]] and enabling her bad habits, she ended up becoming a Moriarty-style mastermind. Becomes HarsherInHindsight, when canon itself later reveals just what the Commission has been willing to stoop to, in times past, in order to stay in power.

* [[HesJustHiding She's Just Hiding!]]: Done as a TakeThat to Midnight's death in canon, which the author considered to be arbitrarily pointless (and which also invalidated a fair bit of his setup for Eri's future backstory). In this fic, Midnight was actually taken and held captive by the villains for two years, and replaced with a decoy which everyone ''thought'' was her body.

* TriangRelations: As of [[spoiler: Chapter 27, and at La Brava's urging, the Crawler, Pop☆Step, and Makoto Tsukauchi have agreed to try their hands at a Type 8 relationship – maybe not a full ménage-à-trois, but only because Kazuho and Makoto don't know if their feelings for each other go in that direction yet.]]

** All Might loves American-style junk food, which is justified because All For One [[BigEater requires him to consume massive amounts of calories]].

!!''Flashback'' contains examples of

* CultureClash: All Might grumbles a few times about the differences between Japan and America.

* EmbarrassingRingtone: Absolutely ''everybody'' thinks that All Might's "A Phone Call Is Here!" ringtone is stupid. Even Sir Nighteye, who calls it idiotic to All Might's face.

* EvenEvilHasStandards: All For One being one of LaResistance's most dedicated fighter in the BadFuture falls under this. Eri even refers to him as one of humanity's most stalwart defenders.

* FreudianExcuse: {{Defied|Trope}}; Sir Nighteye digs into Magne's past after All Might brings her in and finds no history of discrimination or abuse over her trans status, suggesting that revenging herself against society is a made-up rationale for her criminal inclinations. This is supported by Magne [[MotiveRant bragging to a plainclothes Toshi]] that [[ForTheEvulz she goes out of her way to hurt people because she likes to and can get away with it.]]

* MonsterClown: The persona of a particularly [[TheDreaded infamous]] villain in America named Mr. Smiles, and a reason why even the most campy villains hate to be called clowns. All Might describes him as someone who looked at ComicBook/TheJoker and said "Hold my beer," outright calling him one of the few people to be even ''worse'' than All For One.

* ChristmasCake: Mt. Lady directly refers to Midnight as a "leather-frosted Christmas Cake" while bitterly thinking about having to do a foot fetish meetup.

* PayEvilUntoEvil: Nedzu subjects Dupe to some well-deserved ColdBloodedTorture after he learns of what he did with Midnight from Eri

* MonsterClown: The persona of a particularly [[TheDreaded infamous]] villain in America named Mr. Smiles, and a reason why even the most campy villains hate to be called clowns. All Might describes him as someone who looked at ComicBook/TheJoker and went, "Hold my beer," outright calling him one of the few people to be even ''worse'' than All For One.

* {{Polyamory}}: With La Brava's help, [[spoiler:the love triangle between Crawler, Pop☆Step, and Makoto is resolved with Pop☆Step and Makoto agreeing to share Crawler. She also teases that the girls' own relationship might be [[RomanticTwoGirlFriendship closer]] than they realize]].

*** Similar to what happened at the USJ in canon, Inko remembered an incident where All Might fought against a [[BearsAreBadNews bear]] villain [[BerserkButton who had put children in danger]].
-->She shuddered when she remembered that time he fought that horrible bear villain. He hadn't been smiling then... and when he was done, ''neither was the bear.''
*** Due to his preparations for the oncoming alien invasion, All Might starts making a bunch of surprise moves which draw a lot of attention for those more familiar with him, and wonder what is going on. When he pulls the ScrewTheRulesIHaveConnections to get David Shields to Japan, his old adoptive brother/sidekick notes he ''never'' does that, and understands that whatever is happening, it is serious. Deadly serious.

All Might describes him as someone who looked at ComicBook/TheJoker and said "Hold my beer.", and even calls him one of the few ''worse'' than All For One.

* NotHyperbole: {{Discussed}} and PlayedForLaughs; Mirio gets distracted while listening to Eri explain the BadFuture, wondering if when she said she took "''all'' the Trigger", she's just being emphatic or if she literally took all the remaining Trigger that humanity had stockpiled.
* ObstructiveBureaucrat: How All Might feels about the Hero Public Safety Commission due to their habit of occasionally trying to establish dominance over him with petty obnoxious nonsense, which would get in the way of him actually being a hero.

* {{Paparazzi}}: A contributing factor to All Might's accidental harem protagonist status is the press refusing to consider that he might want to talk with a woman in private for some reason other than courtship.

** Mount Lady regularly causes property destruction that ranges from the tens of thousands to the millions in damage-costs. The Hero Public Safety Committee covers the bulk of the expense, but she’s still in the red and only getting deeper, no matter how much time and energy she's forced to put into "fund-raising events".

* TookALevelInIdealism: All Might’s without a doubt an optimist, but the injury All for One dished out took some of that away, only pushing forward because the world relied on him. Upon Eri reverting his body to its physical prime, his idealism is worn on his sleeve once more as he resolves to do more than fight villains, but also save those in need, hence his recruitment of Koichi and Danjuro into his agency.

* UnreliableNarrator: The list of villains for recruitment that Eri gave to All Might was very detailed and informative. [[spoiler: It was also written by [[SerialKiller Toga Himiko]], who was biased by her own [[VillainousFriendship kinship]] with the villains and ignored things like crimes committed, justice owed to their victims, and their actual disposition towards redemption without aliens invading. Sir Nighteye [[LampshadeHanging lampshades]] it.]]

* WalkingTheEarth: Mirko is a cross-country itinerant hero with no fixed agency building. When All Might hears the details of how she operates, he can't help thinking of her as a real life [[{{Munchkin}} murderhobo.]]

* WittyBanter: U.S. Hero collegiate programs have this as a basic course requirement. All Might has a bachelor's degree in Tactical Witticism and Repartee.
* YouHaveOutlivedYourUsefulness: [[spoiler: Any villains that Eri doesn’t feel are worth the effort of redeeming or negotiating with, she intends to strip of their quirks and then execute.]]

* {{Polyamory}}: With La Brava's help, [[spoiler:the love triangle between Crawler, Pop Step and Makoto is resolved with Pop Step and Makoto agreeing to share Crawler]].
