Jerome "Doc" Louis is an ex-heavyweight boxing champion, and Little Mac's coach. In the Wii title, he is voiced by Riley Inge. He is very engaged in Mac's training and matches. In the NES and Wii installments, Doc trains Little Mac as he fights throughout the World Video Boxing Association circuits. This often includes Mac running behind Louis as he rides his bike, now one of the most iconic features of the Punch-Out!! series. He also invented the Star Punch, Mac's strongest move. He may have been named after the legendary real life boxer Joe Louis.
