Dragon Ball Z

Synopsis

While Goku is recovering in the rejuvenation chamber inside Frieza's spaceship following the end of the Ginyu Force, Krillin heads to Guru's to get the password. Gohan is left behind to guard the Dragon Balls while Vegeta, the prince of the Saiyans, is taking a nap. On his way to meet Guru again, Krillin sees Dende flying in the opposite direction. He meets up with him, and Dende tells him that he has been sent to deliver the password, and together they head back to Frieza's ship. Once they arrive, they decide to make the wish now so that Vegeta won't get his wish of immortality. Meanwhile, Frieza discovers Nail has been purposely stalling him and threatens to make a move to finish him off. Nail, however, says that killing him won't do any good because Dende is probably the one who has the password for the Namekian Dragon Balls, and that he has given them to the Earthlings. Finally getting the point a little too late, Frieza becomes angry and flies back to his ship. When he tries to contact the Ginyu Force, he finds out that they were all slaughtered by Vegeta, Gohan and Krillin, and vows to exterminate his enemies before they obtain a wish from the Dragon Balls. Dende, Krillin and Gohan bring the Dragon Balls to a nearby island, and Dende summons the Eternal Dragon. This dragon is revealed to be a Namekian dragon with two black horns named Porunga, and upon his rise, the skies of Planet Namek suddenly becomes dark, much to Frieza's surprise, as he continues frantically dashing to prevent the heroes from ruining his dream of eternal life.
