Dragon Ball Kai

After managing to calm down Majin Buu's rage by dealing with the thugs himself, Mr. Satan discovers that the dog is barely alive. Majin Buu manages to heal the dog just in time. As Majin Buu, Mr. Satan, and the dog start becoming closer, Mr. Satan decides to stop taking advantage of Majin Buu's innocence and becomes his earnest friend. However, one of the thugs from earlier shows up and shoots Mr. Satan, which causes Majin Buu to be overcome with anger. After healing Mr. Satan, Majin Buu instructs him and the dog to get away from him. The evil in his body escapes and transforms into a tall, grey, emaciated version of Majin Buu.
