Dragon Ball Z Kai (2009)
S6E3 Headlong Rush into Catastrophe! A One-Hour Time Limit!
Episode Overview
Convincing Super Buu to delay his attack on Earth, Piccolo proposes a one-hour wait so Trunks and Goten can finish training in the Hyperbolic Time Chamber. Seeing the logic in letting his opponents reach full strength for a better fight, Buu reluctantly agrees. This clever negotiation buys the young Saiyans precious time to prepare for the looming battle.
