History Fanfic / ChangingGears

* BeCarefulWhatYouWishFor: Endeavor wanted Shoto to finally use both halves of his Quirk and finally gets his wish during the boy's match against Izuku. But Shoto is clearly [[TraumaButton panicking due to the events that caused it]] and Izuku's hands were badly burnt ''and'' frostbitten from the fight, which reminds Endeavor of his oldest son. The man specifically compares the situation to a monkey's paw.

* ClosetKey: Ochako realises she is attracted to girls in addition to guys during the Sports Festival when she finds herself fantasizing about Kendo.

* CutLexLuthorACheck: Downplayed as most people with healing quirks charge massive fees for their services. Recovery Girl is the only one providing aid for free, and deeply resents the others.

** While under very different circumstances, Izuku still gets Shoto to use his fire and significantly messes up his hands to do so.

* LaserGuidedKarma: Shinsou screwing over Togeiki's friends during the Obstacle Course prompts her to share intel on his Quirk to Izuku, who passes it on to Setsuna. Knowing he screwed over one of her classmates too, Setsuna is inspired to take Shinsou's team's headbands at the last possible moment to deny Shinsou advancement.

* MeaningfulName: The Second and Third Torchbearers get names like the ones they have in ''Fanfic/OneForAllAndEightForTheNinth'' - the only difference is that the Second's name is Soujirou (銃赦), with 銃 = "gun" and 赦 = "forgiveness", with "jirou" being a homophone for "second son".
* MirrorMatch: Izuku's match against Todoroki involves the former using a jury-rigged version of the latter's quirk by speeding up or slowing down the vibration of air molecules around him.

* NoSell: During the USJ attack, Izuku puts the Nomu in Park, which does stop it in place. However, he was expecting the Nomu to die as a consequence of leaving it like that for so long. However, once Park is undone, the Nomu shows no signs of having been harmed at all.

** Shinso shows signs of this for the General Ed students, as he got through the first found of the Sports Festival by forcing his own classmates to literally carry him to victory, and then abandoned them to cross the finishing line. Because of this, Togeike is perfectly happy with sharing the details of his Quirk, which leads to his ultimate defeat.
* TheReasonYouSuckSpeech: When Izuku realizes the reason Bakugo's angry is that he believes Izuku hid his Quirk for a decade just for a cheap prank, Izuku realizes Bakugo's not worth the effort and lets him have it with both barrels.

* SoreLoser: Shinso does not take his loss at the end of the second round of the sports festival well at all. He storms out of the arena while still leaving his teammates under mind control.

* TraumaButton: Shoto visibly panics when Izuku manages to encase him in ice during their match at the Sports Festival, something Endeavor spots as the boy starts flinging both sides of his quirk around at random.

* LGBTAwakening: Ochako realises she is attracted to girls in addition to guys during the Sports Festival.

* ForWantOfANail: Izuku getting the Second One for All User's Quirk instead of the strength enhancement Quirk leads to some changes.
** Izuku gets first place at the Entrance Exam due to using his new power to stop objects, destroy robots, protect others, and even heal injuries. This nets him a sizeable number of Villain Points in addition to his canon 60 Rescue points.
** Second, the Vestige, is furious at Izuku having his Quirk, and keeps trying to angrily communicate with Izuku in his sleep. This means Izuku keeps going to school with less sleep than he is used to, meaning his patience is shorter, as is his control over his verbal filter. While Izuku later talks Second down so he can get some sleep, it still leaves an impact.
** Izuku gets first place at the Quirk Apprehension Test due to working on mastering his new power in the few weeks before U.A. starts.
** Because Izuku wins the fight between him and Bakugo during the battle trial so quickly, Bakugo doesn’t get a chance to fire off his gauntlets, leaving everyone clueless to how destructive they are.
** Izuku gets five votes instead of his canon three while Momo gets three instead of two, as Kaminari, Kirishima, and Aoyama voted for Izuku while Izuku voted for Momo.
** Izuku's improved confidence means that he keeps the title of Class President instead of giving it to Iida.
** Due to the red flags he keeps seeing with Bakugo's behaviour, as well as realizing that his usual LeeroyJenkins tendencies don't always work, Kirishima doesn't join him in attacking Kurogiri, so he ends up in the Ruins Zone with Ojiro.
** While Kaminari, Jiro, and Yaoyorozu still end up in the Mountain Zone, instead of knocking out the villains with Kaminari's Indiscriminate Shock, it's Jiro who does it with an absurdly loud BrownNote which also affects the guy that had buried himself (incidentally saving Kaminari from being taken hostage).
** Izuku using "Park" on the Nomu means All Might doesn't have to fight him, which leads to Shigaraki and Kurogiri running away the moment the Number One Hero arrives.
** Nezu points out to Izuku that, given that he's using a previous Torchbearer's Quirk, there is a high probability he will also eventually be able to use the other One for All's wielders' Quirks.
** As 1-A is formed by 19 people after Mineta's expulsion, Togeike Chikuchi picks up the 42nd slot for the Cavalry Battle, joining Izuku's team.
** Due to the different dynamics within Class 1-A, some of the Cavalry Battle teams are different. The most notable example being ''no one'' wanting to team up with Bakugo, who ends up a (brainwashed) member of Shinso's team.
** Because Izuku and his team stay in the air during the entire Cavalry Battle thanks to Park, Todoroki never uses his fire against Izuku. Izuku's Quirk is also sufficiently different from All Might that there are no indications of a familial connection between them. Both of these together means that he never reveals his tragic past to Izuku.
** Setsuna steals all of Shinso's team's headbands in the last second, which prevents him, Bakugo, and Aoyama from moving on to the final event. Others that are also left out are Kirishima, Ashido, Sero, and Tokoyami. They are replaced by Togeike, Komori, Awase, Yanagi, Kendo, Tokage, and Honenuki.
** Izuku's first fight is with Kaminari instead of Shinso, while Todoroki fights Komori.

* PsychologicalProjection: Bakugo tells himself that Izuku has been planning out his "backstory" to make himself look better because that's what he is actually doing.

* LaserGuidedKarma: Shinsou screwing over Togeiki's friends during the Obstacle Course prompts her to share intel on his Quirk to Izuku, who passes it on to Setsuna, who knowing he screwed over one of her classmates too, is inspired to take Shinsou's team's headbands at the last possible moment to deny Shinsou advancement.

** Todoroki wins his first tournament fight by creating a large glacier, and his next fight is against Izuku.
* InsaneTrollLogic: Bakugo comes to the conclusion that Izuku spent years pretending to be quirkless, causing him to be bullied, for the sole purpose of giving himself the perfect origin story to be the next number 1 hero.

** Izuku still wins the Obstacle Race by propelling himself with a massive minefield explosion, coming ahead of Todoroki and Bakugo.

** Togeike Chikuchi and her Quirk come from ''Fanfic/{{Haigha}}''.

* MyFriendsAndZoidberg
** Within 1-A, Bakugo has become this to his dismay. During the second round of the Sports Festival, none of the "extras" flocked up to him to beg to join his team. And when he swallowed his pride enough to go up to other teams to demand they let him join, they refused.
--> It was like he was a pariah. Like he was Deku!
** Todoroki's behavior when he comes in second at the Sports Festival leaves Ochako convinced he is another bully like Bakugo.
** Shinso shows signs of this for the General Ed students, as he got through the first found of the Sports Festival by forcing his own classmates to literally carry him to victory, and then abandoned them to cross the finishing line. Because of this, Togeike is perfectly happy with sharing the details of his Quirk, which leads to his ultimate defeat.

** Because Izuku and his team stay in the air during the entire Cavalry Battle thanks to Park, Todoroki never uses his fire against Izuku, meaning they don't speak about the former's past.

* OutOfCharacterAlert: When Togeike tries to tell Izuku about Shinso's Quirk, Izuku already knows that it's some kind of mind control - because there's no way Bakugo would be willing to not just team up with Shinso, but actually be one of the back horses.

** Katsuki is right on the money in believing that Izuku manifesting a Quirk at all, much less one that is as strong as Gear Shift, during the entrance exam is suspicious given how they would've been 15 at the time. That said, he mistakenly believes that he was faking his Quirklessness and was trying to create a sympathetic backstory for when he does truly become Pro.

* StunnedSilence: Shigaraki's reaction when he sees that "Park" prevents the Nomu from even falling down a portal.

* VetinariJobSecurity: Recovery Girl makes it crystal clear to Aizawa that Izuku is not to be expelled, because she is not giving up on the chance to have at last a fellow healing hero around. Including strongly implying that if anything happens to Izuku, then for Aizawa's own good he better never come to her for healing ever again.

** Aoyama is convinced that Izuku is also one of All For One's agents, and a much higher ranked one. Therefore the poor mole is desperate to gain his 'superior's' good favor, and thus is working to ingratiate himself with him.

* AlwaysSecondBest: Shouto is frustrated by constantly being one of the better students, but not the ''best'' student, due to both Momo and especially ''Izuku'' constantly outperforming him. While initially he could accept this given how he was aware the best of the best were coming to U.A., for it to continue consistently is quickly undermining his patience. He actually briefly empathizes with his father's own frustrations of always failing to measure up to All Might.

** When Tetsutetsu comes to 1-A and states they were lucky to face some villains, Izuku immediately retorts:
--->'''Izuku:''' Oh, and if one of us died, or was seriously injured? Would that have made you look bad?

** Katsuki is right on the money in believing that Izuku manifesting a Quirk at all, much less one that is as strong as Gear Shift, during the entrance exam is suspicious given how they would've been 15 at the time. That said, he mistakenly believes that he was faking his Quirklessness and was trying to create a sympathetic backstory for when he does truly becomes Pro.

** Due to the different dynamics between the different the members of class A1 some the teams for the calvalry battle are different. The most notable example being no one wanting to be on a team with Bakugo so he ends up a member of Shinso's team.
** becouse Izuku and his team stay in the air the entire calvaly battle Shoto never uses his fire against Izuku stoping the two of them from talking about his past.
** At the last moment Setsuna steels all of Shinso's team's headbands which prevents him and Bakugo from moving on to the final event.

* InSpiteOfANail: Izuku still wins the Obstacle Race by propelling himself with a massive minefield explosion, coming ahead of Todoroki and Bakugo.

* ShoutOut: Izuku's plan during the Cavalry Battle involves creating a platform via Togeike's quirk, floating it with Uraraka's, then freezing it in midair with his. Or as Present Mic puts it:

* StunnedSilence: Shigaraki's reaction when he sees that "Park" prevents the Nomu from even falling down a portal.

** Katsuki is right on the money in believing that Izuku manifesting a Quirk at all, much less one that is as strong as Gear Shift, is suspicious given how they would've been 15 during the Entrance Exam. That said, he mistakenly believes that he was faking his Quirklessness and was trying to create a sympathetic backstory for when he does truly becomes Pro.

* EntertaininglyWrong: After Izuku admits that he "thought he was Quirkless" until the entrance exam, Aoyama comes to the conclusion that Izuku must be another spy for All For One. And since Izuku's Quirk is visibly far stronger than his own with far less drawbacks, despite the Aoyama family's wealth and influence, it means Izuku is much higher ranked.

** As Ochako learns Izuku's name from the video with the notes and learns what "Deku" actually means, she never calls him that way.
* AlwaysSecondBest: Shouto is frustrated by constantly being one of the better students, but not the ''best'' student, due to both Momo and especially ''Izuku'' constantly outperforming him. While initially he could accept this given how he was aware the best of the best were coming to UA, for it to continue consistently is quickly undermining his patience. He actually briefly empathizes with his father's own frustrations of always failing to measure up to All Might.

** When Tetsutetsu comes to 1-A and states they were lucky to face some villains, Izuku immediately has a question:
-->'''Izuku:''' Oh, and if one of us died, or was seriously injured? Would that have made you look bad?

** Izuku gets five votes instead of his canon three while Momo gets three instead of two, as Kaminari, Kirishima, and Aoyama voting for Izuku while Izuku votes for Momo.

** Nezu points out to Izuku that, given that he's using a previous Torchbearer's Quirk, there is a high probability he will also eventually be able to use the other One for All's wielders' Quirks

* GrewASpine: Midoriya becomes more assertive towards Bakugou, ultimately deciding to no longer consider him a friend. Granted, it is initially due to sleep deprivation, but once he gets rolling he commits to it. Although he does have a one-sided conversation with the Vestiges to let him sleep before he ends up being like Bakugo.

** Izuku calls out Tetsutetsu for his words about 1-A being lucky to be attacked by villains, which their peer bitterly regrets once he stops to think about it, and quickly apologizes for.

* AlwaysSecondBest: Shouto is frustrated by constantly being one of the better students, but not the ''best'' student, due to both Momo and especially ''Izuku'' constantly outperforming him. While initially he could accept this given how he was aware the best of the best were coming to UA, for it to continue consistently has is quickly undermining his patience. He actually briefly empathizes with his father's own frustrations of always failing to measure up to All Might.

** Learning about One for All's story and All for One leaves him so numb that it takes two days to shake him out of it.

** Momo and Izuku quickly bond over similar intellectual interests and both being the class reps (with Izuku maintaining this position), quickly becoming friends.
** Recovery Girl is thrilled with the healing applications of Izuku's new power, and gives him lessons to improve its healing abilities.
** Izuku earns the respect of his classmates much faster, including for his intellectual abilities, and remains their class president.

* AlwaysSecondBest: Shouto is frustrated by constantly being one of the better students, but not the ''best'' student, due to both Momo and especially ''Izuku'' constantly outperforming him. He actually briefly empathizes with his father's own frustrations of always failing to measure up to All Might.

* EntertaininglyWrong: After Izuku admits that he "thought he was Quirkless" until the entrance exam, Aoyama comes to the conclusion that Izuku must be another spy for All For One. And since Izuku's Quirk is apparently far stronger than his own, it means Izuku is higher ranked.

** Second, the Vestige, is furious at Izuku having his Quirk, and keeps trying to angrily communicate with Izuku in his sleep. This means Izuku keeps going to school with less sleep than he is used to, meaning his patience is shorter, as is his control over his verbal filter.

* GrewASpine: Midoriya becomes more assertive towards Bakugou, ultimately deciding to no longer consider him a friend. Granted, it is initially due to sleep deprivation, but once he gets rolling he commits to it.

* WhatTheHellHero: Izuku gives a mild one to the Second User (even though they have yet to fully meet) to call him out for making it harder for him by interrupting his sleep with his screams.

* ArmorPiercingQuestion: Upon being complimented by Iida about understanding the Entrance Exam better than him, Midoriya notes that he didn't know about the Rescue Points. He then asks Iida if he wouldn't have saved anyone unless he thought he would be rewarded for it. Iida notes Midoriya's point, and takes it as more proof that Midoriya is the better Hero student.

* CurbStompBattle: Midoriya and Uraraka's fight with Bakugou and Iida in the Battle Trial is hilariously one-sided. Midoriya exploits Bakugou's LeeroyJenkins tendencies, along with using his new power, to let Uraraka capture him in less than two minutes. And that is mostly travel time, with the actual 'fight' being seconds. Facing both of them at once means Iida follows not long after. All told, the battle appears to have taken about five minutes from start to end.

** Izuku gets five votes instead of his canon three (with Kaminari, Kirishima, and possibly Aoyama voting for him) while Momo gets three instead of two (Izuku votes for her).

** While Kaminari, Jiro, and Yaoyorozu still end up in the Mountain Zone, instead of knocking out the villains with Kaminari's Indiscriminate Shock it's Jiro who does it with an absurdly loud BrownNote which also affects the guy that had buried himself (incidentally saving Kaminari from being taken hostage).

* {{Foreshadowing}}: During the Battle Trials, Izuku mentions the ability to put objects in "Park", which leaves them completely immobile even by outside forces. During the attack on the USJ, he uses it on the Nomu which not only leaves it paralyzed but also means it can't escape through Kurogiri's portals, even when one is opened directly beneath it.

* HeroicBSOD: When Izuku realizes that using "Park" is lethal if used on living beings, he vomits.

* SuckySchool: {{Invoked}} by Bakugou. He intentionally picked Aldera Middle School because it was a below average to average school in order to build up a backstory that makes him look like a underdog for his supposed rise to no.1 hero. He assumes Izuku was doing this too with the added "bonus" of doing all that and being Quirkless too to make an even better backstory.

* VetinariJobSecurity: Recovery Girl makes it crystal clear to Aizawa that Izuku is not to be expelled, because she is not giving up on the chance to have at last a fellow healing hero around. Including strongly implying that if anything happens to Izuku, then for Aizawa's own good he better never come to her for healing ever again.

* SuckySchool: [[Invoked]] by Bakugou. He intentionally picked Aldera Middle School because it was a below average to average school in order to build up a backstory that makes him look like a underdog for his supposed rise to no.1 hero. He assumes Izuku was doing this too with the added "bonus" of doing all that and being Quirkless too to make an even better backstory.

* OhCrap: When Izuku realizes the USJ Nomu is completely unharmed after he undoes park, he quickly tells Tsukauchi to make sure it can't see him because it's last order was to kill him and it might still attempt to follow through.
