Dragon Ball Z - Season 3 Episode 22 -

Goku's hair has turned blonde and his eyes blue, as he is surrounded by a gold aura; the fuel of this power being his anger towards Frieza. As Gohan takes Piccolo to Goku's ship, our hero starts to pound on Frieza as the tyrant fires back, but none of his attacks are working against Goku now that he is a Super Saiyan. It looks like Frieza will finally be defeated.
