History Funny / PersonalitySwapAU

* Mirio's reaction to seeing Izuku fight villains: "Midoriya is terrifying. Neat!"

* Todoroki's first impersonation is of Kirishima. The only difference between this and normal Todoroki is that he occasionally pauses and, in full emotionless deadpan, tells the class that they're manly.

* Iida is terrible at the exercise. He can't stop doing his chopping tick and can't reference memes to safe his life. Kaminari has to break character to give him a crash course on the latter.

* When Nezu and Mic have Izuku impersonate Ms. Joke, Aizawa goes into a hilariously petulant spiral of misery, moaning that he's accepting his fate and upcoming death, that they've ruined his problem child and made him a monster, that Izuku's now "terrible. Awful. His goodness is tainted by her," and threatening to quit his job. All the while none of his coworkers have a lick of sympathy and are actively enjoying his suffering. Then Izuku walks in with a big cheery grin and tries to make Aizawa smile, and Aizawa promptly threatens to defenestrate him. After a beat, Aizawa then defenestrates [[ScrewThisImOuttaHere himself.]]

** Later in the series during a presentation project, this gets a CallBack. When Kamimari declares he'll use his presentation to educate the class (read: Iida in particular) on memes, Iida tries to defend himself. Kaminari responds by questioning Todoroki, who impersonated Kaminari on for second swap assignment, about Jared. Todoroki replies, in full emotionless deadpan, that Jared [[MemeticMutation never learned how to read.]]
* Over the course of the next few impersonations (Aizawa and Nezu), the staff are basically in chaos because of Izuku. Present Mic flees his classroom more than once and All Might can be caught in the staff room monologing about how he "misses his boy."

* When Nezu and Mic have Izuku impersonate Ms. Joke, Aizawa goes into a hilariously petulant spiral of misery, moaning that he's accepting his fate and upcoming death, that they've ruined his problem child and made him a monster, that Izuku's now "terrible. Awful. His goodness is tainted by her," and threatening to quit his job. All the while none of his coworkers have a lick of sympathy and are actively enjoying his suffering. Then Izuku walks in with a big cheery grin and tries to make Aizawa smile, and Aizawa promptly threatens to defenestrate him.

** Todoroki then walks into the office and blatantly states: "I need you to kiss me." When Izuku asks what his injuries are, he replies, "Uraraka says I have an empty heart." Izuku replies that [[ObliviousToLove he doesn't think his Quirk can fix that.]]

* Izuku has made the staff flee the break room ''twice.'' Once when "Nemurizuku" and Nemuri get into a passionate conversation about the flaws of Hero education culture, and once offscreen, when Gran Torino!Izuku did something that left ketchup on the floor.

* Because of Gran Torino, Toshinori has apparently been pavlov'd into fearing ketchup.

** Later in the series, during the second swap, this gets a CallBack. When Iida tries to defend himself on his lack of knowledge, Kaminari questions Todoroki about Jared, and Todoroki replies, in full emotionless deadpan, that Jared [[MemeticMutation never learned how to read.]]

** Todoroki then walks into the office and blatantly states: "I need you to kiss me." When Izuku asks what his injuries are, he replies, "Uraraka says I have an empty heart." Izuku kisses him on the forehead and Todoroki bursts into flames.

* Although Iida and Todoroki both swear at the idea, nobody really minds Izuku playing Gran Torino except All Might, who looks traumatized from the moment he spots ketchup in the empty staff room. His reaction to the Gran Torino!Izuku vs. Iida fight ("the exact moment that Yagi’s hopes and dreams shatter, the life leaving his eyes in a single instant") is so funny to Aizawa that the latter starts taking pictures and starts sending them to mutual friends.

* Aizawa's karmic EpicFail in "Recovery (For the Hell We've Been Through)." Because nobody was attracted to Gran Torino!Izuku, Aizawa thinks he can avoid encouraging the "suitors" if he picks someone who's old for Izuku to impersonate. He forgets that Izuku doesn't change his physical appearance while acting, and that Recovery Girl's power is to heal people ''by kissing them.'' The result is Izuku as a full-blown HospitalHottie, wearing a short thigh length dress, labcoat, and stockings, and subject to increasingly obvious requests for kisses by his classmates, [[EvenTheGuysWantHim male and female alike]]. As the day goes on, Recovery Girl's office becomes more and more frequented by students exaggerating or completely making up injuries. By the end of the day, even kids from the other years have shown up looking for Izuku for "healing."

* Aizawa recovers from the previous day by having Izuku be Best Jeanist, the most covered-up hero he can think of.
