Leon Scott Kennedy (Gaiden)

Sometime after the Raccoon City incident, Leon; as a member of an underground anti-Umbrella organization, was sent to eliminate a prototype B.O.W. that was believed to be among the passengers and crew of the luxury ocean cruiser, the Starlight. Upon his arrival, Leon discovered that there had been a t-Virus outbreak on board. At some point, Leon met a young survivor named Lucia, and fought a good candidate for the B.O.W.: a large gray humanoid who could produce tentacles from its abdomen and transform into an amoeba. After 24 hours without contact, fellow operative Barry Burton was sent to find Leon. He was eventually found unconscious.

After he and Barry saved Lucia from the B.O.W. again, Barry left Lucia with Leon. When they saw Barry on one of the security camera's talking to Umbrella, who had contacted him on the way there, they found him, and Leon was seemingly betrayed by Barry. While Barry and Lucia were on an Umbrella-owned submarine, Leon killed the B.O.W., who was trying to destroy the ship's fuel converter, by blowing him into the steam ducts. Afterwards, Barry and Lucia found Leon. In the end, Leon, along with Barry and Lucia, killed the real B.O.W., a fully-grown parasite that had been removed from Lucia's body, with a hail of gunfire. A small cut on Leon's neck was bleeding green blood, meaning he was actually the shape-shifting Tyrant. What happened to the real Leon is not revealed.
