God is a Lovecraftian-like deity in the fictional universe of the Devilman manga and anime franchise.
God is a vindictive sadistic entity. It's true form is that of a huge sphere of light that turns any human who is too close into salt and kills any demon within its reach. An omnipotent being that has complete control over the cycle of death and rebirth in the cosmos. It tortures Satan by repeatedly crushing and ruining all that matters to him, over and over. Trapped within this cycle is the Earth itself, which is the stage for Satan's eternal punishment, the humans themselves suffering the same cycle.
