Dragon Ball Z Kai - Season 7, Episode 03: Head Straight towards the Catastrophe! One Hour Time Limit!!

Trailer

Piccolo's hopes of being able to buy some time are dashed when Super Buu unleashes a powerful homing attack, which targets and kills every human on the Earth except for Mr. Satan, Tien, and Chiaotzu. Piccolo, along with Videl, manages to convince Super Buu to wait for an hour so that Goten and Trunks can train. Meanwhile, Gohan is tired of waiting any longer for Old Kai's power-up. However, he discovers that he has indeed managed to increase his power, so Gohan agrees to wait for the power-up to be completed. Becoming further angered when Super Buu kills an impatient Chi-Chi, Goten barely holds in his anger and joins Trunks in the Hyperbolic Time Chamber after Piccolo informs Goten that Chi-Chi and Gohan will be brought back to life with the Dragon Balls. With Super Buu growing impatient after only thirty minutes, Piccolo tries to buy as much time as possible as he slowly leads Super Buu to the Hyperbolic Time Chamber. Piccolo believes that even if Goten and Trunks fail, they can destroy the Hyperbolic Time Chamber's entrance and trap him there.
