While on their journey to Namek, Gohan and Krillin practice image training. Meanwhile, Vegeta has landed on Planet Frieza 79, badly injured, and, after being revived, heads to Namek to collect the Namekian Dragon Balls once Cui tells him Frieza is already there. After 30 days aboard Kami's old spaceship, Bulma, Krillin, and Gohan finally arrive on Namek. Bulma uses her Dragon Radar and notices that four of the seven Dragon Balls are together already. Gohan senses evil ki, but Bulma reassures them that the Namekians are the sensed people and that they are probably the ones who have them. They notice Vegeta's spacepod fly overhead and land in the distance, along with a second spacepod holding Cui shortly after. Vegeta isn't too thrilled to find out Zarbon and Dodoria are also accompanying Frieza.
