The transformed Goku renews his battle with Frieza and proves to now be far superior to Frieza’s power. Frieza launches several counter-attacks at Goku, but they have no effect at all. As the tyrant stares in awe at his more-powerful opponent, he realizes that his worst nightmare has finally come true – the legendary Super Saiyan has been born! In a desperate attempt to defeat Goku, Frieza hurls an attack down upon Namek itself, in an effort to destroy the planet and everyone on it.
