Majin Buu (KidVegeta)/Dragonball KC

Majin Buu is a character featured in Dragonball KC. He is a super mega fusion of most of the villains of Dragon Ball and he's a pretty serious villain too. Majin Buu is featured in three chapters of the story.

Dragonball KC
In Dragonball KC, as the plot was happening, suddenly appeared. He quickly fused with, then with all of the other villains in hell except for (because Raditz is extremely powerful). His fusion was fearsome, causing and the others to run away in extreme cowardice. When he was Buu Broly, he was stronger than everyone save for the mighty Gogeta. Gokiu, a new fearsome character, is able to beat up Buu Broly, but he still "looses" (allegedly).

Mr. Satan was so scared of Buu Broly that he joined the demon's side. They swapped senzu beans and bodily fluids. Goku couldn't take it. He stood up and gave a speech about how Buu Broly was a terrible one. This cheered up the Z Fighters. Then Goku charged Buu, punched him one time, and killed that piss-poor Buu pretender. It was incredible, and no one knew how Goku was able to pull off such a feat. He didn't tell them, lest he give away the plot.

Later in the story, Master Roshi wanted to see all of the villains break loose from hell for some unknown reason. Miraculously, the others agreed, and Baba let all the villains free. Kid Buu, Super Buu, and Fat Buu all escaped from hell. This was quite extraordinary, since Super Buu and Kid Buu were the same individual. It is unknown how they separated. Additionally, Fat Buu turned good at the end of Dragon Ball Z, so he should not have been in hell. Maybe he raped some ice cream cones to get locked up there, but who knows.
