Wormwood: Gentleman Corpse
Meet Wormwood, the English-accented, beer-drinking, sentient corpse possessing a maggot expat from the Hell dimension. Well, one of them. If he's not attempting to save Earth from demonic, parasitic fungal infections or undead strippers, then he's off drinking with his homemade mechanical sidekick, Mr. Pendulum.
