Dead Cell

From LibertyWiki

Dead Cell is a terrorist group in the Metal Gear universe. The group first appears in Metal Gear Solid 2: Sons of Liberty. The cell is comprised of Vamp, a modern day vampire, Fatman, an explosives expert, Fortune, a female soldier that is seemingly unkillable, and Solidus, the leader and third clone of Big Boss. The members of Dead Cell are all defeated one by one by Raiden, the game's protagonist, although sometimes through unorthodox and temporary means.
