For 10,000 years, the evil Galra Empire has plagued the universe, conquering planet after planet and destroying other races. The only known threat to their power in the legendary giant robot Voltron, whose components are five mechanical lions that combine into a humanoid robot. Seeking to protect Voltron from the Galrans, King Alfor of Altea tied their energies to his daughter Allura’s life force and scattered them across the universe over 10,000 years ago, while Allura, her retainer Coran, and the royal castle were hidden on planet Arus with the Black Lion inside. In the present, the Galra’s path of conquest has led them to Earth’s solar system, which happens to be the hiding place of the Blue Lion. This component of Voltron eventually brought the five new pilots of Voltron-Shiro, Keith, Lance, Pidge, and Hunk-to Arus, where they met Allura and became resolved to defend the universe and defeat the Galra.
