Ebonite possessed a levitating skull that he used as a weapon. (COMIC: Cindy, Cleo and the Magic Sketchbook)
The skull was used as a reservoir for the life energy of those killed in the Arena of Fear. The amount of life energy collected was so great that the skull was almost sentient. After the defeat of Ebonite, the skull chose Munmeth as its new master. (COMIC: Arena of Fear)
