Things You'll Need
Instructions
Power up using the Kaioken technique to reach a level that exceeds Vegeta's; do this by continuously pressing the "L" button on the classic controller.
Repel Vegeta's Galick Gun by countering it with a Kamehameha; do this by pushing the "L" and "X" buttons.
Stay away from Vegeta after he uses a false moon to transform into his great ape form. Use Ki blasts to keep him at bay by pushing the "L" and "A" buttons.
Gradually charge up to maximum power by repeatedly pushing the "L" button.
Activate Kaioken once you achieve maximum power and attack Vegeta with a combo attack; do this by pressing the "A" button repeatedly and then pressing the "L" button to do a vanish attack and chain together your assault. Fire your spirit bomb just before your power runs out by pushing the "L," "X" and "down" buttons.
You may have to repeat steps 4 and 5, but if you keep at it, Vegeta will go down for the count.
