It's a sick world.
Literally -- the universe is an organism, and the creatures of myth and folklore are invading parasites, preying on the native species and disrupting the ordered systems of the world.
It's a sick world, and Dr. Vincent Morrow's here to treat it. Headhunted into an exciting new career in the black arts after his excommunication from the medical community, Morrow serves the world with both hands -- one in magic, one in medicine -- as earth's protector. Earth's Witch Doctor.
Witch Doctor is a medical horror comic written by Brandon Seifert and illustrated by Lukas Ketner.
Collected in Witch Doctor: Mal Practice.
