Eliminator (Resident Evil Zero)

The Eliminator is a biological weapon created from a large monkey by Dr. James Marcus. The primate is highly intelligent, capable of executing commands. Little destruction of brain cells is seen in this subject. This is a striking difference from human subjects infected with the virus, indicating that their metabolism is working effectively.

Their speed is remarkable, so ensure you don't let them run circles around you otherwise you won't be able to target them. Combined with their persistent jumping, these foes should be dispatched as quickly as possible.
