Realizing his pupil Keldor had no intention of releasing him from Despondos, Hordak merged him with an extra-dimensional being called Demo-Man. While this saved Keldor's life, it also drove him temporarily insane and convinced him to open a portal to Despondos and lead what he thought were “his people” to Eternia. Hordak intended to use this ruse as a means to escape once the portal was opened, but the new merged being “Skeletor” was quickly defeated by Oo-larr, the jungle He-Man, and Hordak remained trapped. Soon after, with the help of Evil-Lyn, Skeletor gained control of the powerful spirit inside of him, increasing his abilities ten-fold. He was now the true Overlord of Evil and one of the most dangerous men on Eternia!
