Ah...then I believe we have something similar, actually; it's entirely possible to use alchemy create human bodies that are kept in stasis but are effectively dead - they're empty, nothing more than shells or dolls, really. I've seen them myself, they're unbelievably unsettling - but either way, it's possible to animate them using the soul of one who was previously deceased. That would be the closest thing we have to a zombie, where I come from.

The Homunculi are different; they operate on the same sort of principle, I believe, but they're considered something else.
