History Fanfic / ChangingGears

** 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 verbal filter.

** Izuku using "Park" on the Nomu means All Might doesn't have to fight him, which means Shigaraki and Kurogiri run away the moment the Number One Hero arrives.

** Kirishima was Bakugou's biggest friend in canon. Hear, Kirishima spots a lot of red flags in the latter's behaviour and distances himself from him, and because they are sent to different spots during the USJ incident, they don't form any connection under fire to smooth over the building issues.

* CurbStompBattle: Midoriya and Uraraka's fight with Bakugou and Iida in the Battle Trial is hilariously one-sided. Midoriya exploits Bakugou's 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.

** Due to the red flags he keeps seeing with Bakugo's behaviour, Kirishima doesn't join him in attacking Kurogiri, so he ends up in the Ruins Zone with Ojiro.
** Izuku using "Park" on the Nomu means All Might doesn't have to fight him.

** Second, the Vestige, if 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 verbal filter.

* CutReedRichardsACheck: 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.

* GrewASpine: Midoriya becomes more assertive towards Bakugou, ultimately deciding to no longer consider him a friend.

* HypocrisyNod: Minor example when Izuku finds out that All Might used to be Quirkless himself, and asks All Might why he said Izuku couldn't be a Hero without a Quirk. All Might admits he had been at the end of a bad day, but also acknowledges that, regardless of how everything had gone, it was wrong of him to tell Izuku that, and that he was glad to be proven wrong when he saw for himself that Izuku could be heroic without a Quirk.

* InsaneTrollLogic: Bakugo comes to the conclusion that Izuku spent years pretnding to be quirkless, causing him to be bullied, for the sole purpose of giving himself thr perfect origin story to be the next number 1 hero.

* DramaticIrony:

He notes the hypothetical of Midoriya getting SuperStrength, but not being able to use it like All Might. All Might notes that his advice in this potential scenario might be unhelpful or even harmful. Anyone familiar with canon knows that All Might isn't too far off.

* HiddenDepths:
** All Might has an undergraduate degree in human physiology, and Recovery Girl acknowledges his skill in training the human body.

* RightForTheWrongReasons: Aoyama concludes that Izuku was actually Quirkless before the entrance exam rather than merely believing himself to be so, which is completely accurate. But his logic is based off the idea that Izuku must be a spy for All For One who was given a Quirk, much like himself.

* {{Hypocrite}}: Minor example when Izuku finds out that All Might used to be Quirkless himself, and asks All Might why he said Izuku couldn't be a Hero without a Quirk.

When Midoriya Izuku received All Might's Quirk, he wasn't expecting it to make his hands glow blue. Or allow him to use SuperSpeed. Or let him launch objects at high speed. Or let him heal people. Or let him stop an object's speed, bypassing inertia in the process. Or for All Might to not know what this new Quirk is, or how to use it. Needless to say, Midoriya has some Quirk experimenting to do, with All Might ready to do what he can to help!

** Midoriya ultimately decides to stop trying to become Bakugou's friend or treat him as such.

* AtrociousAlias: The Third wielder saddled Yoichi with the Vigilante name of Dumas. While the idea behind it is great, to the public at large, it gets pronounced as "dumb ass." Yoichi is ''not'' happy when he finally learns about this.
* AwesomeByAnalysis: In preparation for the Sports Festival, 1-A decides to work together and put a plan in place. Cue Izuku, Monoma, Ochako, and Momo putting together a detailed analysis of all past events, and their predictions for what will happen this year, all culminating in Nedzu himself calling them to the principal's office to commend them for getting so many details right.
