34 days after leaving Earth, Bulma and the others finally arrived at their destination, Planet Namek. Bulma gets angry at Gohan and Krillin for walking on the planet, without testing the air first. Krillin and Gohan fail to understand her however. Bulma then checks the Dragon Radar, and it shows signs of Dragon Balls on the planet, much to everyone's expectations. Then they feel a huge Ki, at first they think it is a Namekian, but then they realize Vegeta has landed on Namek.
Vegeta is thinking out loud, when Cui arrives on Planet Namek as well. Cui says, Frieza has finally ordered for Vegeta's demise and he will be one to do it, much to the amusement of Vegeta. Cui then claims it is time for the rivals to fight it out, he also mocks Vegeta's currently low power level making Vegeta laugh, Vegeta tells Cui of his newly learned ability to hide his power level. Vegeta then disposes of Cui quickly.
Meanwhile, back on Earth.. Seven of Korin's Senzu Beans were prepared, aiding in healing Goku 's wounds. Then, upon hearing of the situation with Gohan and his friends on Namek, Goku boarded the Saiyan spaceship modified previously by Bulma's father, Doctor Briefs, and left the Earth. His course was set for Planet Namek. And waiting for him there was Frieza.
Frieza had attacked many villages on Planet Namek, and already collected five Dragon Balls. Frieza demands to know where the remaining two Dragon Balls are. The Namekians refuse to tell this, since they will not betray their friends, even when facing death. Frieza orders Dodoria to kill them all. Before Dodoria manages to hurt the last survivor, Gohan and Krillin save him, and flee from Dodoria to their spaceship. This angers Dodoria, and he blasts the country of Namek to smithereens, believing to have killed Gohan and Krillin in the process, he takes off, alone. For Vegeta this is a huge opportunity.
When facing Vegeta, Dodoria suggests that Vegeta leaves immediately, he wants to let him go just this once, but Vegeta sees behind this and tells Dodoria he is scared because he saw him battle with Cui. Dodoria believes his scouter was broken back then.
When Vegeta starts to dominate Dodoria, he tries to make Vegeta let him go in exchange for a secret about Planet Vegeta. Vegeta demands Dodoria to tell him immediately, thus Dodoria tells Vegeta that it was Frieza who destroyed his planet, not a collision with a huge asteroid. Vegeta however, does not care about his race, family or planet's destruction, he only cares that Frieza used him, angering him more than anything. Vegeta then executes Dodoria immediately, and is amazed at his own skills.
