Oni! Shigaraki Tomura

Tomura was a slim young man with pale skin, tinged yellow teeth, and a great deal of wrinkles around his eyes from scraping at allergies that irritated the surrounding skin since his childhood. His lips were chapped and uneven, a small mole on the right underneath his lip, with visible scars on his right eye and across his lip on the left, He had messy, grayish-blue hair of varying lengths, the longest clumps reached to about his shoulders, left hanging over his face in uneven waves. His eyes and mouth were normally obscured, but when visible, they were usually stretched wide in a rather maniacal manner, their bright red irises looking very small. Hair had grown longer, and he adopted a hooded leather coat that he wore over his costume. He also added two additional red cords to connect the hands on his shoulders to the hands on his chest.

Tomura always had a desire to kill All Might, but out of an impulsive expression of anarchy towards a society that hurt him and caused his mental instability.

He didn't care for his or almost anyone else's life, having no qualms about performing evil deeds like murdering innocent people. Tomura was initially perceived to be a "man-child": arrogant, selfish, dependent, and demanding, becoming irritated or downright angry if things didn't go according to plan and using video game terminology showing his detachment with reality and childish mentality. Unlike his mentor, Tomura lacked subtlety, preferring to eliminate problems through force.
