What is the Majin Buu Saga?

The arc opens as comedy, Gohan in a superhero costume at high school, then darkens in stages: a tournament infiltrated by Babidi's agents, Vegeta willingly accepting the Majin mark to force his rematch with Goku, and Buu himself, a monster older than civilization who turns cities into candy and absorbs heroes one by one. Toriyama leans back into gag instincts inside an apocalypse, which is why the arc divides readers more than any other.

Fusion is its mechanical legacy, in both forms: the Fusion Dance, which produces Gotenks and demands perfect synchronization, and the Potara earrings, which produce Vegito and were drawn as permanent until later series revised the rule. The arc also gives Vegeta the franchise's most quoted act of growth, his admitted inferiority and his sacrifice against Buu, an explosion that fails and is meant to.

The manga's final chapters are quiet on purpose. The Genki Dama that ends Buu is powered by ordinary people across Earth, Mr. Satan, the fraud hero, saves the world by asking nicely, and ten years later Goku leaves the tournament to train Buu's kind reincarnation. The 42nd tankobon volume's ending is the one every later series, GT, Super, and Daima alike, must position itself around.

Collectors treat the last volumes as the anchor of a complete run: a full 42-volume Japanese tankobon set, or the 34-volume kanzenban that re-collects the same chapters, both end here. The kanzenban's final volume carries Toriyama's revised ending pages, drawn for that edition, making it the one place the manga's ending exists in two official versions.
