Vamp is a member of Dead Cell, and he is also very good friends with Fortune. Vamp is also a bi-sexual, and him and Fortune's father, Scott Dolph, were lovers.

History
Most of what Vamp did before the events of MGS2 is unknown. The earliest events we can uncover is that Vamp and his family were involved in an accident in a church and the entire of Vamp's family were killed. Vamp was trapped under it's remains for a long time and survived by feeding on his family's blood. This gave him a blood-lust that earned him the codename Vamp.

Eventually he joined Dead Cell, and aided Olga's Mercenary army and Solidus Snake in taking over the Big Shell and take President Johnson hostage. He single handedly wipes out SEAL Team 10's Alpha Zero Squad. Later on when Raiden is fighting Fortune, Raiden fires at Fortune but the bullets swerve and hit Vamp in his Chest and between his eyes. When Raiden leaves Vamp awakes and tells Fortune: "I have died once, I can not die a second time." He then pilot's Metal Gear RAY when Solidus' Harrier is shot down by Raiden and catches the Harrier in RAY's "mouth" and brings it to safety. Then, when Raiden is attempting to save Emma Emmerich, Vamp appears and challenges Raiden to a fight to the death. When Raiden succeeds Vamp seemingly dies once again.

Then, when Raiden and Emma are then taking the Water Bridge route to get to the Shell 1 Core, Vamp appears once again and stabs Emma before Raiden snipes him and kills him for a final time.
