After Majin Buu dispelled the evil from his body a tall, thin, gray emaciated form appeared. This Evil Buurepresents the dark side of Fat Buu and has the bulk of the original Majin Buu's power, being that Majin 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 Majin Buu. He is a polar opposite of the"good" Majin Buu in all aspects apart from apparel, (except for him having a dark blue cape where Fat Buu has a purple cape), including the color of his flesh (a drab grey), his incredibly thin body, and gravelly manner of speech.
Evil Buu immediately proceeds to mercilessly eliminate crazed gunman Van Zant in the mountains. He then battles against Majin Buu, with the evil incarnation quickly gaining the upper hand and consuming "Good Majin Buu" after reflecting an attack meant to turn him into chocolate. Evil Buu then eats the chocolate Good Buu causing them to re-fuse, this time with the evil on the outside instead of the inside resulting in Super Buu.
Evil Buu appears as a playable character in the Dragon Ball Z Budokai Tenkaichi series, under the name "Majin Buu (Pure evil)." In these games, he can use the Kamehameha but doesn't know the Chocolate Beam. His stats are very similar to Fat Buu's.
