Meet Charlie Sinclair.
Charlie was the main character of my senior thesis. He’s a reformed demon who hunted down criminals and creatures of supernatural origin as part of an underground, otherworld investigation agency. He was inspired by Cloak, of Cloak and Dagger, and must feed on the energy of others in order to survive - and you guessed it, the energy of the pure is way more nourishing than the energy of the evil. Though Ocho, his sidekick, sometimes slips in his oath to only kill the guilty, Charlie does his best to remain strong.
