Disregarding all of the psychological and deeply personal reasons Deku’s quirk shocked Bakugou in their first battle, his reaction is justifiable. I would be whacked out of my fucking mind too if the weedy kid in my class who couldn’t even talk back suddenly could breAK ALL OF HIS BONES AND NOT EVEN FLINCH.
Middle School Bakugou: *throws (1) punch* “HOW DO YOU LIKE THAT DEKU?!?!”
Deku: *bawling his eyes out* “K-Kacchan please”
High School Bakugou: *exploded half a building* “YOU’LL ALWAYS BE A USELESS NERD!!! NEVER A HERO!!”
Deku: FUCK YOU YA BASTARD I DON’T FEAR DEATH *blows up arm and the rest of the building*
