Wulk was a Myte, and was unusually large for his race. Because he was so different to the others of his kind, Wulk had been made fun of all his life, and lived in isolation in a forest far beyond Velpine City, the city of his people. Wulk also knew the ancient Myte fighting technique. Because of this, he was a strong fighter, and even proved to be a match for He-Man. Skeletor and Wulk planned to trap He-Man, The Guardians, President Pell and General Nifel in the caves of Loom, but their plan was foiled, and Wulk fled with the Mutants.
