Strongest Vs. Strongest/Battle Of The Strongest

When Coola first arrives, he hits Gokou in the back with a sneaky blast and severley injures him. Krillin rushes Gokou off to hide while Gohan gets some senzu beans. Unfortunately, as Gohan returns with the senzu beans, Coola's henchmen find him, and Piccolo has to defend him from Coola. Gokou and Krillin come to their aid, and in the ensuing battle the heroes do manage to defeat Coola's henchmen, but not before Gokou and Krillin get beat up.

After Gokou gets healed with a senzu bean, his one on one fight with Coola begins. Things seem to be going Coola's way until Gokou gets sick of losing, and transforms into a Super Saiyan. The startled and scared Coola fires his best energy blast at Gokou, but the Super Saiyan easily smacks it right back where it came from, knocking Coola right off the planet and straight into the sun.
