Malik

Malik was once the demon overlord, Mephistopheles. He turned his back on Satan after being on earth for thousands of years, making deals with mortals so Satan can have more souls at his command. But after in the mortal world for so long, Mephistopheles fell in love with Humanity. So he changed his name to Malik and became a demon hunter. Even though Mal loves humanity, he's still appears cold and closed off and can be a jerk at times, preferring to work alone, he can be very very caring at times
