Izuku Midoriya

Izuku is somewhat short for his age, his round face is framed by a short mess of fluffy dark-green hair which sticks up at odd angles around his head, casting noticeably dark shadows onto itself. His eyes are large and somewhat circular, their irises the same green color as his hair, which at times are very watery, and are usually stretched quite wide, giving him an innocent, energized appearance. He has a set of four symmetrical freckles in diamond formations, one on each cheek.

Izuku externalizes his observations through endless mumbling, a habit that annoys or creeps out his peers. Izuku often writes down his observations in a variety of notebooks he titles as Hero Analysis for the Future, checking on them regularly during school activities or at night.

Izuku putting others' lives above his own can go to the extreme, to the point where he has little to no self-preservation. Katsuki speculates that the bullying Izuku received for being Quirkless made him internalize that his life has less worth.

This can make Izuku somewhat short-sighted, as he continued to break his arms, despite warnings he could permanently paralyze them and cut his hero career short. Eventually, Izuku listened, adapting his battle style to not put so much strain on his body. Though when he's in a particularly tight situation, he'll pull back on old habits.

This audacious spirit, while initially viewed as perplexing or even insane by others, is also recognized by many, and has earned him the loyalty, gratitude and respect of characters that were previously antagonistic towards him such as Tenya Ida, Shoto, Hitoshi Shinso, Kota Izumi, Sir Nighteye and even the Hero Killer: Stain.
