Dragon Ball Z Kai: The Final Chapters Episode 18 English Dubbed Episode Title:Don't Sell Super Saiyans Short! Vegeta and Goku's Full-Bore Power!.Episode Description:Vegeta outmatches Pui Pui in terms of fighting skill. Babidi changes the stage to match that of the high gravity planet, Zun, where Pui Pui is at his top fighting form. This makes no difference to Vegeta, who obliterates his opponent and opens the way to the next floor. Believing that the Saiyans should not be underestimated, Babidi sends in his next warrior, Yakon. Babidi changes the stage to match that of Planet Ankoku. Even with the aid of the pitch black darkness, Yakon is no match for Goku's keen senses. When Goku turns Super Saiyan, Yakon uses his ability to consume light and sucks in Goku's energy, which causes Goku to revert to his normal state. Rather than finding an alternative way to fight, Goku feeds him more Super Saiyan energy until Yakon explodes from being overloaded. This allows Goku and the others to move onto the next stage.
