At the World Martial Arts Tournament grounds, Vegeta unleashes an energy blast at Goku. Goku tries to stop the blast but is sent flying, and it explodes in the spectator seats. With the tournament grounds in a panic, Goku and Vegeta square off. It turns out that Vegeta purposefully fell under Babidi’s magic in order to make Goku get serious. Learning of this, Goku announces to Babidi that he will fight with Vegeta. Not even Supreme Kai can stop Goku and Vegeta’s battle. Babidi changes the stage to an uninhabited wasteland, just like Goku requested. He then tries to manipulate Vegeta with his magic, but the prideful Vegeta brushes him aside. Gohan and Supreme Kai head into Babidi’s spaceship, and the battle between Goku and Vegeta begins.
