Main article: Majin Boo
Evil Majin Boo or Super Buu (Funimation dub) is the transformed state of Pure Evil Majin Boo after eating Majin Boo. It is the second strongest form of Majin Boo and the second most powerful (both being second to Pure Majin Boo) of the four main villains of Dragon Ball Z.
The first thing that Evil Majin Boo did after he transformed (aside from cracking his neck and powering up) was to brutally kill deranged gunman Smitty by going down his throat in liquid form and blowing him up. He did not kill Mr. Satan, as part of Majin Boo inside him remembered Satan, so he went to Kami's Lookout (as he could now sense energy signals). He asked to fight Son Goten and Trunks, and after trying to stall him (during which time Super Buu did a Human Extinction Attack to kill all inhabitants of Earth except Mr. Satan, Bee, Tenshinhan, Chaozu, and anyone at Kami's Lookout or Karin Tower), agreed to let him wait an hour before fighting them. During this time, Chi-Chi slapped him for killing Gohan and he turned her into an egg and crushed her.
Boo soon got impatient of waiting, so he got Piccolo to take him into the Room of Time and Space, where Goten and Trunks were training. Piccolo deliberately took the longest way possible to stall him before they reached the chamber and Goten and Trunks fused into Gotenks and fought Evil Boo. Eventually Gotenks turned Super Saiyan and used Super Ghost Kamikaze Attacks on him to severely damage him, and even reduce him to molecules, but he was able to come back together. When Gotenks faked being unable to make any more ghosts, Piccolo destroyed the entrance to the chamber to trap them in. In desperation, Boo yelled "LET ME OUT!", unwittingly using his Dimension Scream technique, (a technique where the user screams so loudly, they tear open holes between dimensions) to open a portal to the outside world, where he escaped to. He turned Kuririn, Artificial Human 18, Marron, Yamcha, Puar, Oolong, Bulma, Videl, Muten Roshi, Gyumao, and Mr. Popo into chocolate and ate them. When Gotenks turned Super Saiyan 3 and escaped, he fought Buu again, and was at a slight advantage until he lost his Super Saiyan 3 power and his fusion wore off. Son Gohan arrived shortly after, powered up by Rou Dai Kaioshin, and beat up Boo, who self-destructed in an attempt to kill Gohan. Boo survived and regenerated, and tricked Goten and Trunks into fusing again. He then absorbed Gotenks and Piccolo and transformed into a much more stronger and intelligent form. His antenna became a head tentacle.
Boo fought Gohan and gained the advantage, forcing Rou Dai Kaioshin to give Goku his life and give him Potara earrings to fuse with Gohan. Tenshinhan attacked Buu, and Goku arrived with the earrings, but Gohan lost his earring before he could put it on. Goku fought Buu, who lost most of his power as Gotenks' fusion wore off inside him. However, he turned his severed head tentacle into liquid and used it to absorb Gohan, drastically increasing his power into one of the most powerful villains in Dragon Ball Z.
Goku eventually fused with Vegeta to become Vegito and manages to injure Evil Boo, with Boo's liquid form going down his throat ineffective, as well as his Super Ghost Kamikaze Attack, and even turning him into candy did not stop him, forcing Boo to turn Vegito back. After taking several huge beatings (often being blown to bits or losing several limbs), Boo absorbed Vegito. This was Vegito's plan all along, as he wanted to rescue the others. After separating (due to Boo's stomach acid dissolving the fusion), Goku and Vegeta found Goten, Trunks, Piccolo, and Gohan absorbed, and cut them down from their cocoons (referred to by Boo as "people pods"). Returning to his original Evil Majin Boo form, he entered his own mind to fight Goku and Vegeta.
They could not destroy him inside his own head, and he nearly absorbed Vegeta at one point, but eventually Vegeta tore down the original Majin Boo. Instead of turning back into Pure Evil Majin Boo, however, he turned into Pure Majin Boo.

- An interesting thing to note about Super Buu is that for most of his transformations his personality changes. He doesn't have much personality as Evil Buu; After becoming Super Buu he gains a soft spot for Hercule (due to having Majin Buu inside him); he becomes more intelligent after absorbing Piccolo and Gotenks; when he becomes Kid Buu he turns into a mindless killing machine; and he becomes a good person when reincarnated as Uub.
