Kephri was an Osiran who took on the role of the beetle god in Egyptian mythology. He was trapped by the members of his own race inside a Scarabaeus, which was coincidentally used as a set-piece for a mummy horror movie by Hollywood movie producer Monroe Stahr.
However, the sarcophagus was revealed to be empty, because the god had infested and incubated in the living but decaying body of Raschid Karnak. It was only when Peri took off the ankh Karnak was wearing that liberated Kephri from his body. The insectoid god then summoned a swarm of locust which consumed Seth Rakoff and tried to do the same to the entire world.
