Muscle Man

Muscle Man (?) is an F-rank villain, and is one of roughly seventy villains recruited by the League of Villains for the U.S.J. Incident, making it a minor antagonist of the U.S.J. Arc.

Appearance
Fitting to his name, Muscle Man is tall with a bulky, muscular frame. He has spiky, dark brown hair that's styled upwards, and wears a unique mask that obscures his entire face. He also wears a simple green T-shirt, baggy jeans, and brown shoes.

Personality
Not much is known about his personality. Given he is one of the many villains willing to challenge the staff at U.A. High School, Muscle Man can be assumed to be quite confident in his abilities.

U.S.J. Arc
Thousand Eyes is one of the several villains who invaded the U.S.J. led by Tomura Shigaraki. Eraser Head confronts them to protect the students. While the hero was in the middle of fighting Steel Bulwark, Muscle Man sneaks from behind and tries to punch Eraser Head. Eraser Head easily ducks and kicks Muscle Man away before flinging down Steel Bulwark on to the other villain using his Capturing Weapon. Steel Bulwark, Muscle Man, and two other unnamed villains were all incapacitated at once. Muscle Man is later arrested when the Pro Heroes arrived.

Quirk
Charging Muscles: Muscle Man's Quirk allows him to charge up strength in his muscles, enhancing the strength of an attack into a powerful blow. However, if he overcharges his Quirk, he suffers from severe muscle soreness.
