Save the World (戦いは終った...ありがとう孫悟空, Tatakai wa Owatta... Arigato Son Goku) is the twenty-sixth episode of the Cell Games Saga and the one hundred ninety-first overall episode in the uncut Dragon Ball Z series. The episode first aired on June 30, 1993. Its original American air date was December 26, 2000.
Realizing that Gohan is unable to push Cell back by himself, Piccolo returns to the battle site and launches a Masenko at Cell, but nothing happens. The rest of the Z Fighters soon join him, except Vegeta, who stays back believing that their efforts will not make a difference.
From the Other World, Goku tells Gohan to throw all his remaining ki into the wave, and Gohan gains the advantage for an instant. As they struggle to assist Gohan against Cell, the Z Fighters soon find themselves at the mercy of Cell's power, and they are all forced to fall back. Just as it looks like Cell will win, Vegeta launches an energy sphere at Cell. The blast distracts Cell long enough for Gohan to release all of his power into his Kamehameha wave. With Goku saying, "Now's your chance!" to his son, Gohan screams and releases all of his energy at Cell. Cell screams as the Father-Son Kamehameha consumes him. The energy wave is strong enough to vaporize every cell in his body, preventing any possibility for regeneration. Cell is finally destroyed once and for all, and the Earth is safe again.
- Cell is destroyed by Gohan and Goku.
"I am perfect!!"
"At last, the terror known as Cell has been silenced forever. The battle is won, and the world is safe once more. Thank you, Goku, for all that you gave. The Earth will miss you."
