[ Sorry, dude, Ulaz doesn't know much about Earth, but this is one of the few things he does. Though speaking of knowing things, right, a human wouldn't know anything about Voltron. He's got to explain it. ]

There exists a weapon of incredible power called Voltron. It is a gigantic robot, composed of five ships in the shape of lions. To keep Voltron's might out of the hands of the Galra Empire, the lions were separated and hidden away on remote, unimportant planets. The Blue Lion is associated with water, and so it was sent to a planet with a lot of it: Earth.
