Dragon Ball Z Kai Season 3 Episode 19

After Piccolo debriefs everyone on Cell’s objective, Vegeta states that he intends to develop a power that surpasses even that of a Super Saiyan. Trunks and Krillin go to Dr. Gero’s laboratory, where they discover a set of blueprints for Android #17. In hopes that the prints will allow Bulma and Dr. Briefs to uncover a weakness in the androids, they take the prints before destroying the developing Cell and the rest of the laboratory. Trunks goes to find Vegeta while Krillin delivers the prints to Bulma. Several days go by, during which Piccolo and the others are unable to locate Cell. However, back at the Kame House, Chi-Chi and Master Roshi start hearing thunderous booms on the island and rush to the window to find a fully recovered Goku launching Kamehameha waves into the horizon. The three share a joyous moment before Goku turns serious and states that he’d fare no better against the androids than Vegeta did. Also like Vegeta, he states his goal of surpassing the level of Super Saiyan.
