"Maximum Desperation" (フリーザ決死のフルパワー Furīza Kesshi no Furu Pawā, lit. "Desperate Freeza's Full Power") is the three hundred twenty-first chapter of the Dragon Ball manga.
As Goku charges at him, Frieza thinks to himself that he can finish the fight in thirty seconds at full power. Goku stops his approach when he sees Frieza power up, and notes that his ki is rising. King Kai tells Goku to attack while Frieza is building his power, but Goku refuses, saying that he wants the chance to see Frieza at full power. King Kai is flabbergasted, but Goku says that he will win. King Kai tells him that this is not a game and to think about the others, but Goku says that he will avenge Krillin and that Gohan and the others will be fine. Goku tells Frieza that he will wait until he is at full power, and says that this is what Frieza truly wanted.
Meanwhile, Gohan flies around Namek trying to find Bulma. He feels Frieza's ki increasing and wonders what is happening. He finally finds Bulma, who complains of boredom and asks when Goku is going to get to Namek. Gohan tells her that he will explain everything later. Kami contacts King Kai and tells him that Mr. Popo has gathered the Dragon Balls of Earth. After learning that Earth's Dragon Balls can wish back groups of people at once, King Kai tells Kami to wish everyone killed by Frieza back to life, hoping that Guru will return to life as well.
Kami agrees to do so, and Yamcha, Tien Shinhan, and Chiaotzu agree to stay dead for another year. King Kai tells Kami to hurry, as Namek is about to explode. On Namek, Frieza has reached full power, and he and Goku trade blows. Frieza tells Goku that this was just a warm-up for his final attack, and that Goku would be the strongest in the universe if not for him. Back on Earth, Mr. Popo has used the Dragon Balls to summon Shenron.
