Extradimensional entities are non-corporal beings assumed to be composed entirely of pure energy and thought. Very little is known about them except for the fact that they presumably exist outside our concepts of time and space. They appear to have nearly god-like omnipotent powers, but are governed by strict rules and regulations for how these powers may be used. As with their mortal counterparts, it appears these entities have alignments ranging from good (those seeking justice and order) to evil (those seeking destruction and chaos). Over the years, several entities have manifested themselves within the comic, while even more have been indirectly mentioned.
