An amalgamation of Caraka, a former human host of the Spectre, and Sekuba, a demon, Azmodus was a recurring enemy of the Spectre, hosted by Jim Corrigan.
In the mid-late 1940s, Azmodus was bound to a human host, in much the same way that the Spectre, Aztar, was bound to the corporeal body of Jim Corrigan. He remained trapped inside a mortal shell for more than twenty years because reality could not abide having two entities as powerful as Azmodus and the Spectre to remain on Earth untethered. When Azmodus' host body died, his essence was consigned to the astral plane reality of Tholagga.
Note:Azmodus should not be confused with the demon Asmodeus or the fallen angel Asmodel.
