Piccolo was the smartest until the Buu Saga, and then he became the comic relief since Krillin wasn't there much anymore. However I liked when he beat the hell out of Goten and Trunks for sleeping, at least they salvaged a little of the old Piccolo. Yeah right Piccolo being tricked by Gotenks, by far the least intelligent fighter in the series, Piccolo playing volleyball, Piccolo with his mouth to the ground and eyes as big as the moon, Piccolo unable to gage his enemies like he always used to. Thatâs not the Piccolo that I know, they royally but the screw to him in the Buu Saga. He kicked some serious ass in the Cell Saga though.
