Masked Muscle made his only appearance in the SNES version of Super Punch-Out!! as the third boxer in the Major Circuit as well as the #1 for the Major Circuit Championship. He appears to be a luchador as well as a boxer, and is the game's equivalent of Soda Popinski.
In the SNES version of Super Punch-Out!!, he cheats by spitting in the eyes of his opponent to blind him for a short time (see his cornerman say "Spit in his eyes"). As revealed in the instruction manual he was banned from professional wrestling after spitting his substance on his opponent. He then turned to boxing and earned the titles of amigo to none and prince of the cheap shot. This opens him for an attack. He also headbutts his opponent with a great deal of force (also cheating). He shouts "Adios!" when he wins by KO. If you run out of time, he will spit twice at your direction. His palette swap is Super Macho Man.
