Adder

First appearance: Resident Evil 1

Information

This small, venomous snake was infected by the T-Virus and began to multiply uncontrollably. It detects prey by sensing body heat, and attacks in groups.

It thrives near water and prefers damp places. It has faster reflexes than a typical snake and will jump to bite into humans on sight. While the green-skinned Adder will only cause flesh wounds, the red-skinned version releases.
