Izuku is small for his age, his round face 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, and are usually stretched quite wide, giving him an innocent appearance. He has a set of four symmetrical freckles in diamond formations, one on each cheek, but despite these prominent traits, he is often described as being plain-looking.
