Duel on a Vanishing Planet (とことんやろうぜ!! 消えゆく星に残った二人, Tokoton Yarouze!! Kieyuku Hoshi ni Nokotta Futari) is the twenty-seventh episode of the Frieza Saga and the one hundred second overall episode in the uncut Dragon Ball Z series. The episode first aired on August 7, 1991. Its original American air date was October 27, 1999.
Goku and Frieza continue their battle on Namek, with only two minutes before the explosion. In the Other World, King Kai explains to Yamcha, Tien Shinhan and Chiaotzu how Frieza damaged Namek in a last attempt to kill Goku.
On Earth, Grand Elder Guru explains to everyone that they were all wished to Earth in order to escape from Namek's explosion, but Goku chose to remain on Namek in order to ensure Frieza's defeat. Piccolo is shocked and saddened at the news, but touched by Goku's bravery. He begins reflecting on their past history, starting from when Goku defeated King Piccolo, which led him to produce the egg from which Piccolo would hatch; their eventual, climactic battle at the World Martial Arts Tournament, where despite Piccolo's advantages, Goku still won, leading Piccolo to believe Goku was different from the others; their battle against Raditz, where Piccolo finally fulfilled his dream of killing Goku along with Raditz, but did not feel as satisfied as he thought he would thanks to Goku's bravery; and how Goku's power has now far surpassed Piccolo's, but still does not desire more.
Vegeta interrupts, claiming Goku only remained on Namek to fulfill his desire for combat. Though he is upset that Goku will die, he hides it by appearing happy that Goku will be killed and removed from his life forever. He begins provoking Gohan into fighting with him by insulting Goku and threatening to bring everyone under his control by wishing for immortality with Earth's Dragon Balls, but Piccolo cuts him short, telling him that those Dragon Balls, which were used to revive him, have now turned to stone (although for only a year), irritating Vegeta.
Goku and Frieza's battle escalates to the final phase. During the battle Frieza unleashes his 100% Death Ball in an attempt to destroy Goku, but Goku deflects the Death Ball into space, where it explodes. Frieza angrily screams out that only one minute remains until Namek explodes.

- Almost all the events in this episode do not appear in the manga and are mostly filler for the anime; particularly Vegeta's enthusiasm about Goku's fate.
