Jump Ultimate Alliance

So, this is my idea: A group of destructive Anime Villains are out to destroy everyone and everything on Earth. Luckily, there's a bunch more heroes than there are villains. So, they team up as their enemies have to protect the planet. A little vague, but my idea is clear. You take any character made by Jump, be they anime or manga, and place them on sides. However, ANY character can be on ANY side. Just reead my submission below and you'll understand.

CHARACTERS
Name: Kid Buu
Age: ???
Gender: Male
Appearence:
Bio: After the events of GT, Buu is revived, not remembering the events from before. All he can recall is his name. He is reborn in Tokyo, where he is forced to hide from the people. However, when he reads a super hero comic book, he remembers who he is. However, realizing he was wrong in what he had done before, Buu decides to turn over a new leaf as his overweight counterpart had done.
