Gotenks

Gotenks is the Fusion Dance fusion of Goten and Trunks, combining the powers of both young half-Saiyan warriors into a single, incredibly powerful but immature fighter. Despite his youth and arrogance, Gotenks possesses power that rivals some of the strongest fighters in the universe. He was the first character to achieve Super Saiyan 3 through fusion, and is known for creating elaborate and uniquely named attacks. His overconfidence and childish behavior often undermine his immense potential, as he tends to play around rather than fight seriously even in dire situations.
