In Hell, Damian-a demon mutt-had been put through torture at the hands of his father. Four-thousand years later, he is still wracked with the incessant memories of pain. Hardened by his past, he is cold, ruthless, and has grown a knack for killing every vampire in sight as a way to relieve the fire burning within him. Insert human here, and his stone emotions get a good breaking. Guest starring the dark, not-so knight in shining armor, Satan.
After having a strange and cruel nightmare, Damian Wayne felt more violent and vengeful and not himself. The other Titans got suspicious and thinking that Damian was trying to kill himself. Damian must find the demon who made him this way and end him.
