History Fanfic / Switchblade

** Because [[PointOfDivergence Izuku is never even offered One for All, Nighteye has no reason to be hostile to Izuku and their relationship is a lot better, with Nighteye even bonding with him over their shared experience of receiving terrifying visions that they don't understand.

** Todoroki picks [[ShoutOut Zuko]], purely to spite his father.

* AdaptationalNiceGuy: Katsuki is a nicer person in this fic since Izuku's disappearance forces him to [[HeelRealization reevaluate his own behavior much earlier]]. He becomes a much calmer and more approachable person as a result.

** Because Izuku is never even offered One for All, Nighteye has no reason to be hostile to Izuku and their relationship is a lot better, with Nighteye even bonding with him over their shared experience of receiving terrifying visions that they don't understand.

* AccidentalTruth: [[spoiler: During the Battle of U.A., Izuku tells Nagant that he's seen War Dog on the battlefield in an attempt to distract her from sniping the heroes. Nagant dismisses him because he couldn't give her any relevant details... only for War Dog to ''actually'' arrive, tearing her way through PLF soldiers to get to Shigaraki, then going after Nagant herself when the major tries to shoot her.]]

* CallBack: In Chapter 11, when Izuku and Shigaraki meet at the USJ, the latter recognises the former when they say ''"You!"'' while Izuku lets out a confused "Me?". [[spoiler: In Chapter 84, as Izuku watches Shigaraki gets killed by Destro, Shigaraki once again recognises Izuku and manages to say "You" while Izuku calmly says "Me"]].

** [[spoiler:Tokoyami, Hawks and Dabi are killed at the Battle of Gunga Mountain.]]

* DeathSeeker: [[spoiler:Izuku discovers that he used to be suicidally depressed before his disappearance, to the point where he was seriously considering taking Katsuki's [[SuicideDare "advice"]]. It's why he was so willing to let his possessor use him for their mission, because he felt like he had nothing to lose and this way he'd at least have a "death worthy of respect" should their mission fail. He's horrified to discover this about himself in the present day, calling himself stupid for ever wanting to throw his life away]].

* ForWantOfANail: Because Shouto doesn't tell Izuku about his family life during the Sports Festival, Izuku being unaware of any problem does not help him try to use his fire then.

* TheHandler: Under normal circumstances, undercover heroes have an HPSC-approved handler whom they report to. [[spoiler:When Izuku infiltrates the Paranormal Liberation Front after they take over the prison where he was detained, he manages to re-establish contact with his side and False Flag becomes his handler, being his point of contact with them]].

* LaserGuidedAmnesia: [[spoiler:Most of the people who hear of Switcher possessing Izuku says Switcher ''should'' have left a note after the fact. It turns out the reason he didn't is because War Dog's own possession abilities combining with his resulted in an unusual interaction that resulted in him forgetting about most of the week he was possessing Izuku]].

** [[spoiler:The Battle of U.A very nearly ends with a devastating loss for the Chain, when the PLF manage to build a teleportation device that subverts the teleporter-disrupters that the heroes had set up, and allows them to enter the ''heart'' of Chain territory. They proceed to cause extreme destruction and loss of both hero and civilian life in their attempt to breach U.A.'s walls. Only the timely arrival of Best Jeanist, War Dog, and other reinforcements prevent the villains from succeeding, turning the battle into a draw, with near equal losses on both sides.]]

* DeathSeeker: [[spoiler:Izuku discovers that he used to be suicidally depressed before his disappearance, to the point where he was seriously considering taking Katsuki's [[SuicideDare "advice"]]. It's why he was so willing to let his possessor use him for their mission because he felt like he had nothing to lose and this way he'd at least have a "death worthy of respect" should their mission fail. He's horrified to discover this about himself in the present day, calling himself stupid for ever wanting to throw his life away]].

* MistakenForRacist: Or Mistaken for Quirkist, at least. After Monoma tries and fails to copy Izuku's quirk during their match in the joint training, Izuku assumes that Monoma is biased towards him for being a Quirkless hero-in-training when the latter keeps trying to corner him to talk and later takes the matter to Principal Nedzu. Monoma later clarifies that he wouldn’t have bothered Izuku about it, considering that his own parents are also Quirkless, and that the real reason he wanted to talk to Izuku was that [[spoiler:Izuku ''does'' have a quirk, one given to him by All For One]].

* OnceMoreWithClarity: [[spoiler:After Izuku learns from False Flag that Switcher's true Quirk is that he can body surf, every single memory of the original Meta Liberation Army generals he has makes sense. He didn't somehow have the memories of multiple MLA generals in his head. They all came from Switcher who occasionally rode his fellow generals' bodies]].

* BittersweetEnding: Leaning more towards the sweet. Japan has suffered through a terrible CivilWar where many people lost their lives, including children and members of [[spoiler:U.A.'s Hero Course, like Ashido]], those who survived have many years of recovery ahead of them, and it's strongly implied that [[EndOfAnEra the Hero industry will no longer exist in its current state]]. However, ultimately [[spoiler:the worst villains and threats to peace have been wiped out or arrested, those remaining are able to reach an accord with the Chain and negotiate a peace treaty, and Izuku managed to reunite with his friends and family and finally has the closure he's been looking for since his disappearance, deciding to spend some time running Black Forest with Switcher]].
