Dragon Ball Kai • S01E53 : The Final Blow, Son Goku... Planet Namek Scatters Throughout Space
On Earth, Guru finally passes, but before his death, he gives his power to the Namekian Moori, making him the new Elder. Meanwhile, on Namek, the dying Frieza begs for mercy from Goku. Despite his better judgement, Goku cannot ignore Frieza's pleas for help and gives the tyrant some of his own energy before departing. However, Frieza lets his pride get the better of him and unleashes one final energy blast at Goku, but the Super Saiyan easily repels the blast right back at the tyrant and seemingly destroys Frieza. Goku then attempts to escape in Frieza's spaceship, but is unable to make it take off. Namek finally explodes and it appears that Goku perishes along with it.
