Dragon Ball Z

Synopsis

As Guru enjoys seeing his people alive on Earth, the time has come for him to go, but he passes his powers to Moori, as the next Eldest Namek. Back on Namek, Goku once more advises Frieza to give up his evil ways and live the rest of his life peacefully. However, as the Super Saiyan flies away toward Frieza's spaceship to depart from the dying planet, Frieza refuses to accept defeat and instead uses the power given to him by Goku in a last-ditch attack to finish off Goku off, but an enraged Goku easily finishes off Frieza with a final blast attack.
