Goku powers up with the three-times Kaio-ken and attacks Vegeta with his increased power and speed. Vegeta is filled with rage as he's realized that Goku's power level exceeds his own, so he attempts to destroy Earth with his Galick Gun technique. Goku counters this with the Kamehameha wave and overcomes Vegeta's blast by using the four-times Kaio-ken. Vegeta then searches for the moon to transform into a Great Ape and increase his attributes. Realizing the moon has been destroyed, Vegeta releases a ball of ki that simulates the moon, and uses its energy to transform into a Great Ape. Krillin and Gohan sense Vegeta's increased power and decide to return to help Goku.
