It is assumed that he cut it so the support department could use it to manufacture him a hero costume that would work alongside his Quirk. In his hero costume, Mirio wears a white skin-tight top with the number '1000000' (one million) stamped across his chest in a bold, yellow font. The trimming on the top and shoulder pads are made in a matching fashion. On his waist, two green lines act as a belt, along with some lines of similar appearance on his shoulders, which dip in places to form two V’s. Mirio also wears baggy dark blue pants and white knee-high boots. He wears a red cape as well as thick gloves of matching color. Mirio’s costume is then topped off with a white visor with yellow lenses.
Mirio normally comes across as an extremely goofy and very energetic individual with some peculiar habits.
