Mighty Mask is one of the finalists in the 25th World Martial Arts Tournament. Apparently, Mighty Mask did not fare well in the previous World Martial Arts Tournament. He never gets to fight in the competition as he is knocked out by Trunks before the tournament begins. Trunks and Goten then steal his costume and fight in the tournament as Mighty Mask until Android 18 exposes them.
He was lying about then backstage (unconscious) when some of the World Tournament staff found him.
Mighty Mask is only shown in Dragon Ball Z
