[Doc Faustus]

There are stories about demonic ghouls eating the flesh of the dead. And yes, they aren't by nature undead but ghouls are a lot closer to Romero zombies that voduon zombies are. If you want to be really specific, the closest creature to the zombie as we know it, according to Jonathan Mayberry's awesome book They Bite is called the Craquehe (I have no clue if I'm spelling that right and the book is upstairs). But, since the defining quality of ghouls is that they are supernatural cannibals that devour the flesh of the dead I think it's a moor apt phraseology than zombies, which are harmless and tragic.
