Gotenks is the creature that results after Trunks and Goten perform the fusion dance. He has a tendency to over-dramaticize the situation a bit (Alright, a lot), and makes up names for all of his attacks. Since Gotenks is young and naive, he believes that he can defeat anyone. Most of his assaults are incredibily stupid and ineffective, but he'll squeeze in a few that do some damage.
