Nocturnals: Black Planet (Nocturnals #1)

Doc Horror knows there are sinister forces at work trying to bring the downfall of the human race. They have already ravaged his home planet, and now he has traveled to Earth to try and stop them once and for all. Once here, however, he finds that this world's inhabitants aren't all sweetness and light themselves. Some of them are busy creating freakish mutations out of their fellow man, and others are helping the invaders in their quest for domination. An outcast, Doc Horror is forced to live by the dark of night, and there he finds compatriots who must also shun the light of day. Polychrome, The Gunwitch, Starfish, Firelion, Komodo, and The Raccoon have all their share of knocks from humanity, but they want to save their homeworld anyway, and they don't care how many monsters stand in their way.
