Fanfic / My Hero Academia Entropy

Go To

Entropy(Fanfiction)/Entropy(Archiveofourown) by Imperium42 is a My Hero Academia Fanfic.

Maybe it was All Might's betrayal that finally broke him. Maybe it was the torment from his friends, day in and day out, or the crushing weight of society's collective dismissal of his existence. The reason isn't important anymore- only the consequences. Two years after he and three other students vanished from U.A., Midoriya Izuku is the leader of the fastest-growing group of villains in Japan, and no one is left to stand in his way- no one aside from All Might's successor, the next Symbol of Peace.


All orderly systems descend into chaos. No one is immune to entropy, heroes least of all.

  • Attack the Mouth: Overlap with Tongue Trauma when Toga cuts off Tsuyu’s tongue.
