Enji is a tall, sturdily-built man with a very muscular physique. He has short crimson hair, which he wears spiked up around his head, and sharp turquoise eyes. His beard and mustache appear to be made of fire, but when he voluntarily turns off the flames on his face, a slight amount of stubble shows around his jaw. Shoto has described his father as a prideful and ambitious man, driven by his goal to surpass the No. 1 Hero, All Might.
