My Hero Academia is packed with terrific action scenes, but despite all the fighting, surprisingly few characters got themselves killed in the main story. My Hero Academia has generous plot armor for the heroes and villains alike, since pro heroes are supposed to capture villains and the heroes use the power of hope and friendship to survive anything the villains can throw at them. Still, some fatalities are inevitable, and a handful of characters have died on-screen in the My Hero Academia anime.
