My Hero Academia's main character is Izuku Midoriya/Deku because he has the true heart of a pro hero, and that's what inspired All Might, the symbol of peace, to grant him One For All. Deku lived up to All Might's expectations with his actions and his idealism, and a few of his best classmates have cleared that bar, too. However, the story's actual main trio of great heroes isn't Deku/Shoto/Bakugo. It's Deku/Shoto/Ochaco.
