"The Birth of a Fused Super Warrior! His Name is Gotenks!!" (誕生！合体超戦士 その名は、ゴテンクス！！, Tanjō! Gattai Chō-Senshi Sono Na wa, Gotenkusu!!) is the one hundred thirty-first episode of the Dragon Ball Kai anime.
After some dubious persuasion from Gokū, Old Kaiōshin reveals he has the ability to draw out someone's true power beyond their limits, though this turns out to be a lengthy process that can take over a day to complete. Meanwhile, Goten and Trunks try out the Fusion for real, but an error in the Fusion results in the merged fighter, Gotenks, ending up with a failed transformation. After another failure, the pair eventually perform a successful fusion and transform into the true Gotenks who, confident that he can defeat Bū with his current power level, goes off in search of Bū, despite Piccolo's warnings.
