Universe 11: Babidi, Fat Buu and Dabura
Universe 11 (第11宇宙, Dai jūichi uchū) is the designation given by the Vargas. This world represents the ideal situation for the magician Babidi in which he has successfully gained control over Majin Buu.
Universe 11 is the "unseen timeline" originated by the first Trunks's time travel. In this universe, Trunks from Universe 15 comes to tell the Z Warriors about the arrival of the Androids but no Cell is present because he didn't made the Time Travel yet. Without the feeling of the menace of Cell, Kami decided that wasn't necesary the fusion with Piccolo. Also, he forbids the Z Warriors from training on the Hyperbolic Time Chamber arguing that the Androids are not dangerous enough to use it. With only conventional training, the Z Warriors are barely capable of fighting and the Androids and the controller made by Bulma to destroy them is destroyed in the process. However, thanks to the intervention of Android 16 and Goku, they managed to get a compromise with the Androids to not kill any humans untill they have a rematch. Eventually, the Androids befriend the Z Warriors and are integrated into the group. However, Majin Buu is revived years later, being able to defeat the Z Warriors (and most likely Eastern Kaioshin) and is established as the strongest being in the universe. Also, Dabra manages to survive somehow. Buu also seems much more amenable to following Babidi's orders than his Universe 18 counterpart.
- Majin Buu - This version of the fat Majin Buu remains under Babidi's influence. Majin Buu easily defeated Bujin of Universe 6 in the first round of the tournament. In the second round Buu is declared the winner after the Southern Kaioshin of Universe 1 allows himself to be absorbed in an attempt to free the Kaioshins of Universe 11 and is declared to have forfeited after remaining inside for too long. He loses to Uub of Universe 18 in round three.
- Dabura - Demon King of the Realm of Darkness. Dabura is under the control of Babidi. Dabura faced Cell of Universe 17 in the first round and was defeated after being massively injured and exhausted.
- Babidi - Magician, son of Bibidi, the evil wizard who originally created Majin Buu. Babidi was able to release Buu from his seal and control the Majin for his own uses. Seems to have an interest in Uub of Universe 18, however it is stated by Salagir that Babidi did not know about his heritage, so his motives for healing him are not fully known.
