Sergei Vladimir

Former Soviet colonel. Dedicated to Spencer's ideals, he commands an elite unit pledged to defend Umbrella's interests. He is also one of the few people with perfect viral adaptability, a trait thought to be as rare as one in 10 million. He worked on T-A.L.O.S. in the Raccoon City underground laboratory until he transferred to the Caucasus laboratory of Umbrella's Russian branch.

(T-A.L.O.S.: Tyrant-Armored Lethal Organic System, a Tyrant that can be completely controlled using the processor embedded in its brain. Its body is armored with a special alloy for greatly increased resistance to heavy weapon fire.)
