He is a muscular man who attends the 28th World Martial Arts Tournament.

Dragon Ball Z:
In the tournament, he is matched against Trunks. Despite clearly over-ranking him, Trunks is hesitant to participate in a match with Otokosuki due to his overt homosexuality.

Dragon Ball GT:
Otokosuki later appears during the Black Star Dragon Ball Saga of Dragon Ball GT, where he is now an employee of Capsule Corporation. Otokosuki is seen admiring Trunks as he passes by.

Trivia:
In Japanese, Otoko Suki means "man love", a reference to his obvious homosexuality.
