Giant Bat (Resident Evil Zero)

Unlike most other mammals, this T-Virus has shown what effects it can have on a host that is compatible. The massive increase in size of this bat makes it a tough opponent.

This battle can be an annoying one, as not only are you getting bothered by the smaller bats, but this larger one has attacks that can knock you over. Using the Grenade Launcher against this creature is the best option.
