Tooru Rikiishi

Joe's rival in Ashita no Joe.

Tōru Rikiishi is Joe's most personal and significant boxing rival. The two first meet in the juvenile detention center, he was a boxer but was sentenced to the juvenile detention center because he punched an audience member half to death after they said that the match was rigged in Rikiishi's favor, enraging him. Joe challenges Rikiishi without knowing he was once a professional boxer and manages to punch him in the face once before Rikiishi knocks him out in one punch. He is quintessential in motivating Joe to start taking boxing seriously, even if his only reason is to beat Rikiishi in a rematch.
