Before Krillin deals the final blow to kill Vegeta, Goku intercedes. He asks Krillin to allow his selfish Saiyan wants and let Vegeta live, as he wishes to train harder and challenge him again. Krillin reluctantly agrees and Vegeta leaves Earth. Master Roshi, Bulma, Chi-Chi, and Korin fly to where Goku, Gohan, and Krillin are. They gather the bodies of their deceased friends and set off to the hospital. Krillin informs them that Kami is a Namekian, and that the planet Namek should have more inhabitants able to create Dragon Balls. After brainstorming on how to get there in a reasonable amount of time, they realize that Nappa's capsule is still a working vessel. Bulma decides to run it through some tests and see if it is still viable.
