Yep, at night he is like a freakin' god, he can create anything he can imagine out of the darkness, and he can summon up an unholy army of darklings. Being a former mob hitman, he finds this ability real handy when in need of a weapon. He also seems to be pretty strong / durable. But at dawn, all his creations turn to ash and he is powerless / mortal? The Darkness has regenerated Jackie from bones fragments before having protected itself within a cavity in a tooth!
But, if he ever get's a woman pregnant, he'll die and those voices in his head can get annoying.
