Mighty Mask Character Facts

Mighty Mask is one of the finalists in the 25th World Martial Arts Tournament. 
In the 25th World Martial Arts Tournament, he never gets to fight 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 (though they did not know who Mighty Mask was and first thought his name was "Spopovich"). When they end up fighting Android 18, they realize that she is more formidable than anticipated, and become Super Saiyans in hopes to turn the tide of the battle. However, this quickly becomes their downfall as Android 18 instantly recognizes them and uses a Destructo Disk to cut the costume in half, thus exposing them and disqualifying them from the tournament.
