"Chaos Reigns at the Tenka-Ichi Budōkai" (天下一武道会大騒然, Tenka-Ichi Budōkai Dai-Sōzen; Viz "And the Crowd Goes Wild!!"; Literally meaning "Chaos Reigns at the Number One Under Heaven Martial Arts Gathering") is the fifty-first chapter of the Dragon Ball manga.
As everyone at the Tenka-Ichi Budōkai is stunned at Gokū's transformation, Gokū begins his rampage on the tournament by tearing up property, causing everyone to run out of the dangerous vicinity. While Kulilin pleads to Gokū to change back to his child form, Yamcha explains that there's little point in doing so, as he explains that Gokū transforms into a giant monkey when witnessing a full moon. While Yamcha orders Pu'ar to shapeshift into scissors to cut off Gokū's tail, this revelation leads Jackie Chun to fire a full-powered Kamehameha, seemingly killing Gokū as the giant monkey disappears.
