Dragon Ball Vol. 31 — Manga Raw / Buy Official

After killing Babidi, Buu splits into good and evil; the evil Buu absorbs the good and becomes Super Buu. Super Buu wipes out the western capital and storms the lookout, turning people into sweets. Piccolo flees into the Hyperbolic Time Chamber with Goten and Trunks, who succeed at fusion and become Gotenks. Training inside, Gotenks awakens Super Saiyan 3, then steps out when the time limit hits and matches Super Buu blow for blow. Galactic Donuts and the Super Ghost Kamikaze Attack even land, but he plays too long, the fusion drops, and even a second fusion is caught in a blink. Super Buu absorbs Gotenks, then Piccolo, taking power and strategy at once. Hope on Earth dies; all that remains is Gohan, still unlocking his potential in the Kaioshin realm.
