Dragon Ball Z Kai (2009)

S3E11 The Hunt for Doctor Gero! Discover the Hidden Laboratory!

Piccolo and the others comb the mountains for Dr. Gero’s hidden lab, hoping to stop the Androids before they awaken. Meanwhile, Vegeta ignores their plan entirely, charging off alone with one goal: destroy Android 20. Back at camp, Trunks pleads with his father to listen—to reconsider his reckless pursuit of glory. But Vegeta refuses to hear reason, leaving Trunks desperate to save a man too proud to be saved.
