Dragon Ball Kai

Synopsis

Enraged, Frieza begins unleashing his power. Piccolo arrives on Planet Namek, following being resurrected and wished there. He begins rushing towards the battlefield, and along the way encounters an ailing Nail, on the brink of death. Piccolo reluctantly performs a Namekian fusion with Nail, which increases his power substantially, and begins rushing back to the battlefield. Meanwhile, Frieza attacks the Earthlings with energy blasts, before charging towards Vegeta, after he mocks Frieza. Both Frieza and Vegeta struggle against each other while powering up, though it turns out that they are both evenly matched, much to Frieza's shock. Following this battle, Frieza transforms to his second form, following some goading from Vegeta - and this increases the tyrant's power level to over a million. With his increased power, Frieza easily destroys most of the island they are standing on, before charging at Krillin in the air, impaling him on one of his horns.
