Conquer Castle Grayskull this Halloween in our Masters of the Universe Classic Muscle Skeletor Adult Costume. It features a blue skeletor jumpsuit with attached purple armor and built in muscular torso and arms. Fabric hood and yellow skull mask are also included to complete the look. Skeletor's only goal is power, and he will do anything to get it. He-man is all that keeps him from overtaking Castle Grayskull and learning secrets which would make him all powerful, and capable of becoming master of the universe. Rumor has it that acid burned away the skin on his face in his youth, revealing his skull and making him an even more fearsome villain. This Halloween, dress up like the power hungry Skeletor and have your friend masquerade as his arch-nemesis He-man for a cool costume duo.
