Universe 4 (第4宇宙, Dai yon uchū) is the designation for the third universe visited by the universe-hopping Vargas. The strongest being of this universe is Majin Buu who claims to have absorbed everything useful and powerful in his own universe.


Age 774 - Everything up to this point is the same as the regular DB/DBZ timeline. Except, when Vegeta tries to remove the Fat Majin Buu from Super Buu's body, he's absorbed and Buu takes on his form. Before Buu reabsorbs Gohan, Piccolo, Goten, and Trunks, Gokū transforms into a Super Saiyan 3 and beings to fight him. After a destructive battle, Gokū is absorbed, and Buu reabsorbs the ones that were freed inside him. Buu threatens to blow up Earth, but discovers he cannot due to the Z-Fighters that are in him. He requests Dende revive the dead citizens of Earth, and absorbs Kibitoshin. After Bulma is revived, she's absorbed too.
