Bio: Little, even the gender, is known about this Ghost other than an apparent allegiance to Warlock, as the character appeared only in crowd scenes until becoming the butt (literally) of Hobgoblin's joke in issue #4.
Ghost's head is removable, but, in spite of this always-visible separation, seems to be somewhat held to its perch on the neck of a neutral humanoid body shape in neutral white robes.
