Voltron: Legendary Defender - Season 1

For millennia, the evil Galra empire has plagued the universe by destroying other civilizations and enslaving various races. The only known threat strong enough against empire’s power and plans is the legendary “Defender of the Universe” Voltron, a 100 meter tall robot warrior composed of five lion mechas whose pilots are known as the Paladins. At the crux of the war that ended with the destruction of planet Altea, Voltron was separated by King Alfor of Altea in order to protect Voltron from falling into the Galran Emperor Zarkon’s possession.
