Liquid Ocelot

Liquid Ocelot was the result of the merger of two beings: the spirit of Liquid Snake and the body of Revolver Ocelot via an arm transplant conducted in Lyon, France. After the sinking of the U.S.S. Discovery, Snake and Otacon stole Liquid's body and used it to make people think Solid Snake died on the tanker, which carried Metal Gear RAY. He's the main antagonist.

Two years later (during the Big Shell incident), Liquid planned an opportunity to gain power. Leaking information to Philanthropy regarding Arsenal Gear, Liquid gained full power over Ocelot during the climax of the incident, and seized a model of Metal Gear RAY. Liquid then fled, using Ocelot's knowledge as a Patriot spy to find the Patriots and launch a revolution against them. However, Solid theorized that Liquid was acting on false information and never found them. When Ocelot (controlled by Liquid) was on top of the manned Metal Gear RAY, standing on Arsenal Gear, Liquid said "Why do you think I chose Ocelot as my host?" This would indicate that Liquid somehow arranged for his arm to be attached to Ocelot. Also, Liquid's personality would often take over Ocelot's mind whenever Solid Snake was in close proximity.

From then on, Liquid set up his final steps to plunge the world into total war. By the year 2014, wars relied heavily on armies of mercenaries to do their work, and Liquid capitalized on this. Eventually, the five largest PMC's were run by a "mother company" which Liquid had set up, known as "Outer Heaven". Liquid also kidnapped Naomi Hunter to help him create a third generation version of FOXDIE which directly affects the SOP system many soldiers currently use.
