Appearance:
Although he is one of the most powerful entities in Dragon Ball Z, Majin Buu is often playful and childish, revealing he destroys things for fun simply from old instructions from his master, stopping once told what he was doing was wrong. Though he is playful and silly, his evil side is readily apparent, especially shown when his eyes widen and steam shoots out of the holes on his body. He finds enjoyment in taking the lives of many and shows no remorse, though this is because he treats everything as a game. In battle he fights in a bullying manner, using his immense size to outflank his opponent. During his second battle against Gotenks, Gotenks was preparing the Super Ghosts of his Super Ghost Kamekazi Attack for battle. Piccolo showed Gotenks that Buu had already regenerated from the last Super Ghost attack. Super Buu was also lying on his stomach, drinking a soda (though it looked like a milkshake) and reading a magazine, much to Gotenks's fury and embarassment. Also, when Goku and Vegeta were preparing for battle, Kid Buu was sleeping, much to Goku's surprise. Despite the pleasure he takes in mass-murder, it is later revealed that he only committed such acts because he was unaware of their morality, and because he had been commanded to do so by Babidi, and Bibidi before him. The Daikaioh's presence is more influential in this form than in Super Buu, who is mostly evil and is influenced very little by the Kai. He literally struggles with the evil inside himself, with the evil winning and usurping near complete control, Majin Buu becoming far more dangerous as a result. Buu also possessed an enormous appetite for sweets, shown to far exceed even Goku's eating habits, as Buu was still hungry after he once turned a whole city of people into candy and ate them. He was extremely naive, as he was completely ignorant of Hercule's (inept) attempts to kill him, as well as the fact that Bibidi and Babidi were using him.
Abilities:
Rapid Fire Skin Attack
After detaching a piece of his belly Majin Buu swings it around violently sending giant exploding ki orbs at the opponent.
Belly Attack
This move is only performed by fat Majin Buu. Majin Buu can perform this attack if the person kicks him in the stomach. The person will be unable to take their foot out, and will slowly start to be sucked inward. Majin Buu will expand his belly so the person can fit inside, and then will continue to suck them inside of his belly. The person is being violently squeezed as this happens, violently enough that loud rubbery noises are heard. The person is sucked in very slowly, until they are completely engulfed. Even then, Majin Buu will continue to engulf the person, completely closing off the opening in his stomach. This was used in his battle against Super Saiyan 3 Goku.
Energy Mines
An attack used by Mr. Buu in which he sends multiple tunnels of energy that travel under ground and burst out as dozens of energy balls that fly toward the opponent. While the opponent is distracted by these balls Buu prepares a much larger blast in his hand and fires it while the opponent isn’t looking. He uses this against Kid Buu and manages to blow off his entire left side.
