Hordak is the commander of the Evil Horde. The Horde is a military operation that occupies the planet of Etheria but is constantly being challenged by the heroic members of the great rebellion. Hordak was originally the teacher and mentor of the evil wizard Skeletor. Hordak taught Skeletor all of his magic techniques. The two eventually became bitter enemies which led to Hordak fleeing to Etheria in an attempt to conquer that world. Hordak's plans for conquest and domination are constantly thwarted by the heroic She-Ra and her brother He-Man. The evil villain has the ability to transform himself into various weapons, devices and vehicles (rockets, laser cannons, tanks, etc.).
