Karl

Karl was a UBCS troop. He died during the Raccoon City Outbreak. He was part of a squad under Nicholai Ginovaef ordered to capture or destroy Thanatos, to take its blood.

The plan did not go too well when Nicholai managed to shoot a pod into Thanatos, collecting his blood. This caused "him" to go on a rampage, killing most of the team by punches, inserting his claws into another, and impaling one that managed to get back up.

His character skin is first unlockable in the first Resident Evil Outbreak, howether, not named. A named version of his skin is in the sequel.
