He seems to be a source of unlimited darkness, and can make shadowy copies of himself to do his bidding.
It is initially implied that he is a bit bumbling, but those traits are long gone by the time shit hits the fan in Parable II. He will perform any depravity to further his goals.

THE END IS NEAR. ENJOY IT
