After Gohan's power shatter the mind-control bands that was controlling Piccolo. Dr. Wheelo decides to fight the Z-Warriors, so he pulls his robot body free of the wall, the resulting destruction hurls Kouchin down an energy shaft, and Kouchin's outer coating melts before his own robot body is destroyed. Wheelo fights the Z-Warriors. Piccolo wanted revenge for controlling him, so he lead the assault. Wheelo stop his body and bitch slaps him. He takes down Master Roshi & Krillin first. Goku notice Gohan was about to attack the scientist. Gohan pulled out the powerpole and Wheelo flicks him away (Gohan is now unconscious) leaving Piccolo to catch him, landing next to them is Goku who just caught the powerpole. The namek puts the boy down next to Krillin & Bulma and he goes off to fight Wheelo. Piccolo fires rapid ki blasts (Makosen), while Goku knocked him down with the powerpole. Goku used the Kaioken 3x along with Kamehameha and Dr. Wheelo fired an energy blast. They have the famous power struggle. Goku raised his power 4x so his blast overpowers Wheelo's and hurls him up into space. Dr. Wheelo's fortress is starting to come down. Everyone runs outside while Goku makes a Spirit Ball. Dr. Wheelo fires several energy blasts down on Goku, leaving our hero down. Gohan gets angry and flies up towards the evil scientist. As he flies up in the sky, he sees Piccolo and the namek told him to use his full power. Gohan rams into him, while Piccolo uses his mouth blast and cracks his glass shield. Krillin pops out of the clouds about to attack Dr. Wheelo and he hits the monk in the face. Krillin's thinking, "Why do this always happens to me?" Wheelo tried to destroy the Earth, but Goku creates a Spirit Ball and throws it at Wheelo and he is destroyed up into space.
