Emotional, caring, timid, geeky and resilient. His quirk makes him very physically strong. Izuku is somewhat short for his age, his round face is framed by short fluffy dark-green hair which curls up at odd angles around his head.  His irises are the same shade of green as his hair, which at times are very watery, and are usually stretched quite wide, giving him an innocent, energized appearance. He has freckles and is often described as "not standing out." He is muscular and he is 15.
