History Fanfic / LoopingBackToTheBeginning

* MenInBlack: The last chapter sees Class 1-A acting like this and trolling the school into believing they're part of some conspiracy. They spent ''two loops'' preparing for this too.

* HasTwoMommies: Both of Kirishima's dads attend the parent support group in the final chapter.

* ArchEnemy: The kids rejoice at the thought of having one because it means they're basically set for life. Shigaraki, said prospective nemesis, is ''pissed'' at the idea of a bunch of high schoolers using him as a stepping stone for their careers.

** Unawake Izuku manages to figure out Class 1-A's looping nature rather easily as soon as he notices something weird is going on (it's said that a comment from Bakugou started it). Toshinori was so impressed by his student's work that if he hadn't already chosen the kid to be his successor, he would've pushed him towards the police.

* BaitAndSwitchComment: After Shoto kills his father in one loop, Katsuki berates him - not for commiting patricide (all of Class 1-A figured it would happen sooner or later) but because he involved Izuku in before he got his memories back.

* CrazyPrepared: Mei Hatsume has a form for time travelers requesting her assistance.

** The UA faculty is convinced Aizawa is an impostor after he starts getting more sleep, stops threatening his students with expulsion, and allows them to slack off on their homework.

* DestructiveSavior: Shinsou's first loop had an assignment where the students competed to see who could complete it with the least amount of property damage. Shinsou won, having no property damage whatsoever (he and a group of kids were hiding under a car, which Aizawa counted as 'protecting bystanders'). Second place was Kouda. [[UpToEleven With 1.5 million yen]].

** Himiko concludes that Shoto is a time traveler and that Izuku is a part of his group during the loop he spends with her and Dabi (with Izuku as a vigilante who happens to encounter the trio).

** Not even Aizawa is immune. During Shinsou's first loop, he let the kids do whatever the hell they wanted for a class project, as long as they didn't get ''arrested''. Shinsou won the project with no property damage whatsoever, opting to hide with some civilian kids under a car.

** Chapter 3 focuses on Class 1-A trolling the yet-to-remember-Izuku during the ten months before the Entrance Exam (which Izuku keeps saying they need to stop).

* DestructiveSavior: Shinsou's first loop had an assignment where the students competed to see who could complete it with the least amount of property damage. Shinsou won, having no property damage whatsoever (he and a group of kids were hiding under a car). Second place was Kouda. [[UpToEleven With 1.5 million yen]].

** Apparently, the rest of the class has frequently screwed with Izuku before he regains his memories at the start of the loop (aka, when he gets One for All), to the point that he's told them to stop doing it.
** Izuku's vigilantism.

** Katsuki thanking Unawake Izuku for saving his life is what clues him in to the fact that "something is horribly wrong".

** They've taken to preemptively eliminating all threats at the start of a loop whenever they want to have a normal school year. Or when they want to be the only source of weirdness that year.

'''Shoto:''' He's like All Might, only worse. We're better off not messing with him.

* TemporarilyAVillain: Shoto had to be a villain for one loop after he snapped and killed his father.

-->'''Jirou:''' You can never be too careful with All for One. Overkill is usually the best policy. If that doesn't finish him off we'll have to send in Midoriya.
* {{Troll}}: Class 1-A is this to everyone, up to and including ''each other''.

* EvenEvilHasStandards: Dabi is disturbed by the BlueAndOrangeMorality his little brother and the rest of Class 1-A have adopted.

* IWasJustJoking: When a bored Dabi and Himiko ask Shoto what they should do to pass the time, he jokingly suggests they should rob a bank. And that's how the prodigal son of Endeavor embarked on a career of villainy alongside his outcast older brother and a psychotic teenage serial killer. They spare Tenya's older brother when they happen upon him and Stain (because Shoto, who concealed Ingenium while Dabi and Himiko had Stain distracted, said they only go after assholes and Ingenium was cool).

** They've taken to preemptively eliminating all threats at the start of a loop whenever they want to have a normal school year.

** Unawake Izuku manages to figure out Class 1-A's looping nature rather easily as soon as he notices something weird is going on. Toshinori was so impressed by his student's work that if he hadn't already chosen the kid to be his successor, he would've pushed him towards the police.

** Chapter 3 focuses on Class 1-A trolling the yet-to-remember-Izuku during the ten months before the Entrance Exam.

* GroundhogDayLoop: One that's gone on for so long that the kids have given up on finding the cause and basically just roll with it. They even have set times for when they get their memories for the loop and adjust their plans accordingly.

** This is how Shinsou replaced Mineta in Class 1-A to begin with. Izuku tore through most of the robots at the Entrance Exam, but some of them were still functioning on some level. Shinsou, who was at the same site as him, grabbed a rebar and promptly destroyed those outliers. He wasn't even sure if what he did counted.

* OnlyInItForTheMoney: In one loop, the kids hire Kurogiri to rescue Eri. He assumes they're gonna use her as a hostage and/or that they'll betray him, but they offer him a lot of money and promise the cops will never bother his bar again. After (to his surprise) they actually pay him, he asks about the cops. Jirou casually says they just annihilated the League of Villains, so no one has any reason to be suspicious of his bar.

** One loop sees Aizawa taking a nap during the USJ incident while his students beat the crap out of the League of Villains. They even go as far as sending Thirteen on a prank rescue mission so they can fight uninterrupted.

* SpitTake: Inverted. In one loop where Unawake Izuku figures out the truth, Katsuki ends up ''inhaling'' half a granola bar when Izuku reveals he has deducted Class 1-A's secret.

* DestructiveSavior: Shinsou's first loop had an assignment where the students competed to see who could complete it with the least amount of property damage. Shinsou won, having no property damage whatsoever. Second place was Kouda. [[UpToEleven With 1.5 million yen]].

* IWasJustJoking: When a bored Dabi and Himiko ask Shoto what they should do to pass the time, he jokingly suggests they should rob a bank. And that's how the prodigal son of Endeavor embarked on a career of villainy alongside his outcast older brother and a psychotic teenage serial killer.

** Unawake Midoriya manages to figure out Class 1-A's looping nature rather easily as soon as he notices something weird is going on. Toshinori was so impressed by his student's work that if he hadn't already chosen the kid to be his successor, he would've pushed him towards the police.

* BaitAndSwitchComment: After Todoroki kills his father in one loop, Bakugou berates him - but not for doing that (all of Class 1-A figured it would happen sooner or later) but because he involved Midoriya in before he got his memories back.
* BlatantLies: Todoroki's sister catches him sneaking out a window in the middle of the night with a sword and a bandolier of grenades. His excuse? "There's a raccoon in the garbage."

** Class 1-A hardly blinks at Todoroki murdering Endeavour (they all figured that was going to happen eventually). They're more pissed at him for going to an Unawake Midoriya for help. That doesn't stop them from helping him go on the run, either, or from voting him in as Class President ''that same loop''. To top it off, ''Dabi'' is the person who sees how screwed up that is.
** Todoroki himself has no problem playing the part of a villain for the loop and neither do his friends.

** Chapter 3 focuses on Class 1-A trolling the yet-to-remember-Midoriya the ten months before the Entrance Exam.
** Chapter 4 focuses on Todoroki, who is on the run after murdering his father in a fit of rage.

* GodzillaThreshold: Sending in Midoriya to deal with a problem (usually All for One).
* GroundhogDayLoop: One that's gone on for so long that the kids have set times for when they get their memories for the loop and adjust their plans accordingly.
* IWasJustJoking: When a bored Dabi and Himiko ask Todoroki what they should do to pass the time, Todoroki jokingly suggests they should rob a bank. And that's how the prodigal son of Endeavor embarked on a career of villainy alongside his outcast older brother and a psychotic teenage serial killer.
* ItAmusedMe: The primary motivation for most of Class 1-A's antics. Todoroki's VillainEpisode specifically happened because he'd rather be a villain than stuck in hiding in a crappy apartment, dying of boredom.
* IllPretendIDidntHearThat: During his villain loop, Todoroki runs into Izuku being a vigilante. They both offer to pretend they never saw each other.

** Class 1-A are the only ones that loop. When Mineta lost his spot in the class, he stopped looping, and Shinsou, his replacement, started looping in his stead. This is also how Todoroki continued looping even after the loop where he was forced to go on the run after murdering Endeavour; despite having never attended a single class at UA, the administration never took him off the roster (with Aizawa deliberately choosing not to remind them to). Class 1-A even went as far as voting him in as Class President for that loop.
** This is how Shinsou replaced Mineta in Class 1-A to begin with. Midoriya tore through most of the robots at the Entrance Exam, but some of them were still functioning on some level. Shinsou, who was at the same site as him, grabbed a rebar and promptly destroyed those outliers. He wasn't even sure if what he did counted.
* LukeIAmYourFather: Dabi is Todoroki's older brother. Surprisingly, Shouto and the rest of Class 1-A didn't find out until the loop where Shouto murdered their father.

** Apparently, the rest of the class has frequently screwed with Midoriya before he regains his memories at the start of the loop (aka, when he gets One for All), to the point that he's told them to stop doing it.
** Midoriya's vigilantism.
** In his first loop with the class, Shinsou had to dig... something, with Bakugou and spent the whole time saying they were going to jail. He also knows exactly what it feels like to escape a cement mixer.

** Bakugou thanking Unawake Izuku for saving his life is what clues him in to the fact that "something is horribly wrong".

* PerspectiveFlip: The last chapter sees Class 1-A's antics through the eyes of everyone else. And since it's the loop where they troll everyone that they're part of some conspiracy, it shows how paranoid their school is and how worried their loved ones are.
* RageBreakingPoint: Whenever the loop restarts for Todoroki, he's always woken up by his father dragging him to their dojo for a particularly brutal training session. Todoroki usually just maims him, but after a particularly bad loop, he finally snaps and ''kills'' him.

* SpitTake: Inverted. In one loop where Unawake Midoriya figures out the truth, Bakugou ends up ''inhaling'' half a granola bar when Midoriya reveals he has deducted Class 1-A's secret.
* StrongFamilyResemblance: Todoroki dyes his hair black when he goes on the run after murdering his father. He notes that it doesn't look bad -- in fact, it makes him look a bit like Dabi. [[LukeIAmYourFather Cue Dabi appearing a second later and revealing that he's Shouto's older brother]].
* TemporarilyAVillain: Todoroki had to be a villain for one loop after he snapped and killed his father.

* VigilanteMan: During Todoroki's VillainEpisode, he meets up with Midoriya, who has become a vigilante during his absence. Todoroki strongly implies that this isn't the first time this has happened.

* WorldsStrongestMan: Midoriya, due to having mastered One For All loops ago.

* TemporarilyAVillain: Todoroki had to be a villain for one loop after he snapped and killed his father,

* TemporarilyAVillain: Again, Todoroki.

* TropaholicsAnonymous: In the final chapter, the families of Class 1-A ([[MyFriendsAndZoidberg and Present Mic]]) form a support group over how bizarre their children are suddenly acting.

* PerspectiveFlip: The last chapter sees Class 1-A's antics through the eyes of everyone else.

* SecretSecretKeeper: It's implied that the reason why Class 1-A gets away with their antics is because Nedzu always figures it out at the beginning of the year and lets them do whatever they want, as long as it's in reason.

* CrackFic

* FalseConfession: Class 1-A spent two entire loops gathering information on Monoma (and presumably the rest of Class 1-B) so they can terrify him into doing this. Monoma promptly confessed, even though he had no idea what he was confessing to. Neither did Class 1-A.

* ButtMonkey: The League of Villains, ''especially'' Shigaraki.

-->"I think they may be expecting us."

* OOCIsSeriousBusiness: Bakugou thanking Unawake Izuku for saving his life is what clues him in to the fact that "something is horribly wrong".

* ShowyInvincibleHero: Class 1-A, after so many loops, are so absurdly powerful that very few villains are genuine threats to them anymore (those villains being All for One and a bunch of terrorists who summon a massive sea {{Kaiju}} to do their bidding).

* ThereIsNoKillLikeOverkill: 1-A's default method of elimination for All for One.
