Don't Underestimate a Super Saiyan! Vegeta and Goku's Full Throttle Power! Dragon Ball Kai: Doragon bôru kai : Season 2 Episode 11

As Vegeta easily 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. However, this makes no difference to Vegeta, who obliterates his opponent and opens the way to the next floor. Believing the Saiyans to not be underestimated, Babidi sends in his next warrior, Yakon, and changes the stage to that of Planet Ankoku, but even with the aid of pitch black darkness, Yakon is no match for Goku's keen senses. When Goku turns Super Saiyan, however, Yakon uses his ability to consume light and sucks in Goku's energy, turning him back into normal. Rather than finding an alternative way to fight, Goku instead feeds him even more Saiyan energy until he explodes from being overloaded, allowing Goku and the others to move onto the next stage.
