Mighty Blast of Rage (フリーザ敗れる!! すべての怒りをこめた一撃, Furiza Yabureru!! Subete no Ikari wo Kometa Ichigeki) is the thirtieth episode of the Frieza Saga and the one hundred fifth overall episode in the uncut Dragon Ball Z series. The episode first aired on August 28, 1991. Its original American air date was November 1, 1999.
Now recovered following Goku's giving him energy to survive being cut by one of his Death Saucers, Frieza rises up and cheekily asks Goku what he should do with it, but Goku retaliates by telling Frieza to leave and contemplate his humiliating defeat.
On Earth, Grand Elder Guru realizes that it is now time for him to die again, this time of natural causes. The Namekians gather around Guru to pay him their final respects (and, to their fury, realize that no one from Elder Tsuno's village is present, since they were murdered by Vegeta and not Frieza, and thus not brought back). Guru passes the power of the Namekian Dragon Balls to the second eldest Namekian, Moori, and disappears after bidding his children farewell. Gohan reflects on how Guru unlocked his hidden potential to help him do battle with the Ginyu Force. Gohan, Dende and Piccolo promise not to let Guru down, and regret how Krillin could not see this. Dende then tells them that Krillin can be revived with the Namekian Dragon Balls, since Porunga can revive someone more than once as long as the death was not natural. Gohan is delighted with the news, and even happier since this will apply to Chiaotzu as well.
On Namek, Frieza continues to taunt Goku about how he won the battle so heroically, yet he will be the one to die while Frieza will live on. Goku ignores him and flies off to find a way off Namek. Just then, Frieza is riddled with memories of how he first met Goku, toyed with him, allowed him to unlock his potential and was defeated by him. Blinded by rage, Frieza uses the last of his strength to fire an energy beam at Goku from behind, but Goku sees it at the last minute. Finally deciding to not spare the space tyrant, a furious Goku fires his own beam back at Frieza, which hits him fair and square, apparently obliterates the evil tyrant and avenging billions of people across the universe.
With the battle over, Goku flies off.
