Pure Evil Buu Bio

Pure Evil Buu Bio
After Buu dispelled the evil from his body, the vapor gained this tall, emaciated form. This Buu represents the dark side of Fat Buu and has the bulk of the original Buu's power, since Buu was originally created through pure evil. This also explains why his reaction to the shooting of Mr. Satan was so despicable, and even appalled the Fat Buu. He is a polar opposite of the "good" Buu in all aspects apart from apparel, including the color of his flesh (a drab grey) and gravelly manner of speech. The two Buus fight, with the evil incarnation gaining the upper hand and consuming "Good Buu" after reflecting an attack meant to turn him into chocolate. By consuming the Good Buu, the Evil Buu transformed into Super Buu.

Fat Buu Bio

The first time viewers are introduced to Buu he is in this corpulent form, created through the absorption of Dai Kaiōshin. Rarely do his eyes ever open, and his body is adorned with yellow boots/gloves, a purple cape, a black vest, and white pants. He acts in a childish manner and is the most naive of all the forms, as he is shown to have little or no knowledge of anything around him, even by his own powers. Because he retains an element of evil, Buu is still a danger, because he has almost no sense of an independent mind, so he is easily susceptible to doing whatever someone tells him to do. When Buu struggles with keeping his promise with Mr. Satan not to kill and a desire for revenge with those who wronged him, the internal conflict causes a second Buu to emerge, taking most of Majin Buu's power with himself. That's how the weakest form of Buu is born, known as "Mr. Buu". Deprived of all evil, this Buu is only slightly stronger than a Super Saiyan 2.

Super Buu Bio

In this form Buu enjoys an immense increase in power, as the evil within him has almost completely suppressed the good, and he can be considered a fusion character, for the separate Buus became two distinct entities. Both his height and musculature increase, with his eyes turning full black, save for the irises which are in turn red and white. The gloves previous Buus once wore are eliminated and replaced with black armbands, complimented by a new set of boots that are black and gripped.

He is easily irritated and impatient, entertaining himself by constantly cracking his neck with an insatiable desire to prove himself as the strongest fighter in existence. He first battles Gotenks, who is on even terms with him at Super Saiyan 3. Gotenks eventually defuses, but before Super Buu can press his advantage he is attacked by Gohan. Overwhelmed, Buu successfully schemes to absorb the power of Gotenks and steal the mind of Piccolo.
