Gohan and Krillin arrive at the battlefield, but have to be quick to save Goku, who is being pounded mercilessly. Krillin devises a plan to stop Vegeta: cut off the Saiyan Prince's tail. As Krillin prepares to fire the Destructo Disk, Gohan distracts Vegeta. But, the Saiyan Prince is too smart for their tricks, and foils their plot. Suddenly, Yajirobe appears out of nowhere and cuts Vegeta's tail off. Vegeta reverts to his normal form, but he is still too powerful to be stopped by the remaining Z Fighters.
