Hordak

Hordak is the leader of the Evil Horde, an army of savage Demonic warriors, most of whom wear a red bat symbol on their chests to convey their allegiance. He is the former mentor of Skeletor, one of the franchise's main villains. According to most story media, Skeletor betrayed Hordak and trapped him in another dimension before beginning his own conquest of the planet Eternia. Hordak then returned with a vengeance to take over Eternia for himself.
