Dr. Salvador (Resident Evil 4)

A much tougher variant of the normal Village Ganado, these hosts were not injected with an ordinary Plaga egg. Instead, their heads were made host to the parasite via the bloodstream, which is why they wear a sack over their heads.

This method of infection has made them stronger and more resilient, and with the chainsaw they wield they are capable of killing you instantly if you let them get close enough.
