Introduced as the offspring and reincarnate of the demon Piccolo Daimaō, Piccolo Jr. plans to continue his parent's mission of world domination, and avenge his death at the hands of Goku. Piccolo enters the 23rd Tenka'ichi Budōkai under the alias . Piccolo defeats both Kuririn, who gives up, and Kami disguised as Hero, sealing Kami in the container of the "Evil Containment Wave" after Kami attacks him with the move and Piccolo sends it back in his direction. He then fights Goku in the final round, who tricks Piccolo into enlarging himself so he can retrieve Kami, from there causing many of Piccolo's techniques to backfire on him. Though crippling both Goku's arms and legs, Piccolo is defeated when Goku headbutts him out of the ring, though recovers thanks to receiving a Senzu Bean from Goku, who he promises to defeat as he departs.
