Vegeta is the superior at the beginning of their fight, and not even the Kaio-ken x2 is enough for Goku to gain the upper hand. Desperate, Goku uses the Kaio-ken x3 and overpowers Vegeta. Enraged, Vegeta attempts to destroy the planet with his Galick Gun, but Goku counters it with his Kamehameha and overpowers Vegeta's blast by adding the Kaio-ken x4. Still angry, Vegeta creates an artificial moon and transforms into a Great Ape.
