The evil Galra Empire has plagued the universe for millennia by conquering planets and destroying their inhabitants. Only Voltron, legendary defender of the universe, can stand up to the empire's power and thwart their plans. Standing at 100 meters tall, Voltron is a robot warrior made up of five smaller lion mechas who are piloted by Paladins.
Five space pilots â€“ Shiro, Keith, Lance, Pidge, and Hunk â€“ become the next Paladins after discovering and reuniting the five lions. Together they will learn to form Voltron and combat the evil Emperor Zarkon's dastardly schemes.
