Trailer

The Voltron Force and their allies prepare to take down Castle Doom, the last of Lotor's defenses. But Voltron is nearly destroyed before they can actually land, until Coran pilots the Castle of Lions in its spaceship form to support them. With Haggar having parted ways with him, Lotor's downfall seems definite. But in trying to make certain that his tyranny will never rise again, Sven is drawn into a trap. He is held at ransom, to the horror of all his friends, and has the seemingly impossible job of trying to find a way to stop Lotor from melting their beloved robot before their eyes.
