Weaknesses: His sorcery is not strong enough to overcome Vampire's defensive magic. He is also unable to reverse some of his own spells, notably, the one that reduced him in size.
Bio: Warlock was once friends with Vampire, but now seeks to subjugate humanity, and the two have become enemies. Using a magic spell at the Convention of Terror, he sought to shrink his opponents to helplessness, but also shrunk himself and his followers, probably because of an error in Ogre's preparations. He regularly unleashes his evil monsters upon Vampire's good monsters, which reside at the home of Jack Miles.
Notes: The Warlock/Vampire relationship appears to be modeled upon Magneto and Professor X. In the first issue, Ernie Colón omitted the mustache and beard present the toy, increasing Warlock's resemblance to Magneto.
