Majin Buu is a character from the anime/manga Dragon Ball Z. He starred in the 40th episode of Death Battle, Kirby VS Majin Buu, where he fought Nintendo's Kirby.
A long time ago since the dawn of time, a pink monstrosity known as Majin Buu existed to destroy, until he was trapped in a Sealed Ball. It was discovered by the evil wizard, Bibidi. Bibidi released Buu in order to destroy the universe. After destroying planets, Bibidi went to Earth, dying before he arrived. Before he passed, he made a clone of himself called Babidi to complete his goal. Majin Buu turned out to be a complete lunatic, who would not listen to Babidi. While he was destructive at first, Buu was reformed by a man named Hercule Satan, and started helping the Z Fighters.

Majin Buu is the third Dragon Ball character to be in Death Battle. The first two being Vegeta and Goku, respectively, and the next two being Hercule Satan and Android 18.
Buu is also the second Dragon Ball character to lose a Death Battle, the first being Goku.
Majin Buu is the second combatant to be killed by being thrown at the sun, with the first being Raiden.
Majin Buu is currently the only Dragon Ball character without a Death Battle original voice actor, instead having used Buu's official voice actor, Josh Martin's voice clips from the anime and the Dragon Ball Z Budokai and Tenkaichi games.
This is possibly due to the fact that Team Four Star, who typically does the voices for Dragon Ball characters in Death Battle (such as Goku, Vegeta, King Kai and Chi-Chi) have not yet reached the Buu Saga in their own series, Dragon Ball Z Abridged, and thus either have not chosen a voice actor for Buu or did not want to "spoil" Buu's Abridged voice in a series that wasn't their own.
