Amidst the celebrations hosted by Mr. Satan after Majin Buu's defeat, Piccolo observes Goten and Trunks practicing their fusion technique to become Gotenks, overseeing their training. He remains present when the fused warriors confront the combined threat of Abo and Kado, who merge into the powerful Aka. An early failed fusion attempt by Goten and Trunks causes unintended collateral damage, resulting in the partial destruction of Mr. Satan's newly constructed hotel. Piccolo reacts sternly to this carelessness, joining others in reprimanding Gotenks for the recklessness that caused significant property damage.
