Zombie Slayer [DZ]

If the Doom Slayer became a zombie, it's unlikely he would lose his drive to destroy demons, as his mission is to fight the forces of Hell, and the zombie skin is a cosmetic feature, not a story element. His "uncorruptible" nature and demonic connection would likely mean he retains his mission, even in a zombified state, effectively becoming an unstoppable force of undeath against his enemies, rather than losing himself to the typical zombie fate.
