Name: Gotenks
Bio: Gotenks is the fusion of Trunks and Goten, and so he does not really have a past of his own to speak of. With Majin Buu's threat to the planet growing more dangerous by the moment, the two boys were taught the Fusion Technique, which would allow them to exponentially increase their power, enough to hopefully beat even the powerful Majin. However the pair did not quite have the timing and movements of the dance down, and their first attempt resulted in a fat version of gotenks, with no combat ability to speak of. And the second in a thin version rather similar to Evil Buu. Both were complete failures, but on their third try the fusion went through, and Gotenks was truly formed.
He immediately took on Buu and proved himself the stronger of the two, unfortunately his ego got the best of him, and the fusion wore off before they could finish things. They later fought Super Buu in the Time Chamber, and could have rather easily beaten him as well. But they dragged it out for dramatic tension, and in his confusion Piccolo destroyed the exit. They thought themselves trapped forever, until Buu's screams tore through the dimensions. Gotenks imitated this trick, returning himself and Piccolo to reality.
Gotenks' power is extremely high, however his arrogance is also taken to the maximum, and he loves to show off and play with his opponents to the point that it often comes back to bite him. He also loves to make unusual attacks, which when combined with his overconfidence, and dramatic streak, lead to fights with him being very unpredictable. However as their creativity outweighs their usefulness, they may not be used all that many times each.
