Liquid Ocelot

Liquid Ocelot was the merger of Liquid Snake's "spirit" and Revolver Ocelot's personality. This was supposedly the result of an arm transplant conducted in Lyon, France, after Ocelot's arm was cut off by Gray Fox, during the events of the Shadow Moses Incident.

Biography
The "Liquid" persona first took over Ocelot aboard the USS Discovery in 2007, during the Tanker Incident. He made his presence known to Solid Snake, telling his "brother" that he was "drowning in time" (referring to the accelerated aging process), and that Liquid avoided this fate by living on through the transplanted arm. After hijacking Metal Gear RAY, Liquid screamed through RAY's loudspeaker, "You're going down Snake! With this tanker!!" and proceeded to destroy the Discovery, along with the US Marines onboard, before making his escape. Snake, however, survived the incident, as observed by Ocelot, after Liquid's personality had subsided.

Two years later, Liquid's persona was able to leak information to Philanthropy regarding Arsenal Gear, in order to lure Solid Snake to the Big Shell and use his presence to gain full control over Ocelot. Liquid's personality would often take over Ocelot's mind whenever Snake was in close proximity. However, during the climax of the Big Shell Incident, Liquid's psyche was able to dominate Ocelot's mind completely. The fusion that resulted was Liquid Ocelot. Revealing his intentions to destroy the Patriots, using their own spy's knowledge to locate them, he told both Solid Snake and Solidus Snake that he had in fact "chosen" Ocelot as a host for this very reason, but elaborated no more on this. Once again seizing the original RAY model, Liquid Ocelot crashed Arsenal Gear into Manhattan. Then he fled in search of the Patriots, though Solid Snake theorized that he was likely acting on false information and would never find them.

In the 2010s, Liquid Ocelot set up his final steps to plunge the world into total war and destroy The Patriots. By the year 2014, war relied heavily on armies of mercenaries to do their work, and Liquid Ocelot capitalized on this. By 2014, Liquid Ocelot's mother company "Outer Heaven" (the five largest PMCs) was the largest mother company ever. The first phase of the plan was to use his (Liquid Snake's) own DNA to hack SOP, but it failed.

He placed genetic engineering scientist Naomi Hunter under house arrest and forced her to work for him to access the SOP system and also began cooperating with Vamp. The second phase was to use Solid Snake's DNA, but it failed as well.

Using Big Boss's genetic code to enter the Patriots's AI network, Liquid Ocelot succeeded in taking over the SOP. Calling this plan "Guns of the Patriots", he used it to disable every gun and weapon in the world. After arriving in Shadow Moses, he outfitted with Metal Gear REX's rail gun on Outer Haven, an Arsenal Gear-class battleship that he stolen from the Patriots. He then attempted to use a nuclear warhead launched into orbit from the rail gun to destroy the Patriots' core AI ("JD") in space. While his plan was in motion, Liquid Ocelot had enough time to use one of the mass-produced Metal Gear RAY units which protected Outer Haven.

Liquid Ocelot's plan was "foiled" by Snake and Otacon who infiltrated Outer Haven and implanted a virus created by Sunny and Naomi, which destroyed not only GW, but also spread to the Patriots other AIs, eliminating them once and for all.

Once Snake inserted the virus into GW, he soon passed out. He was then brought atop Outer Haven by Liquid Ocelot, who stated that Snake had accomplished what he had sought all along, to free the world from the Patriots's control, and that Big Boss's Outer Heaven was finally a reality. Liquid Ocelot then helped Snake get back up, seeking one last fight with his "brother"; he was subsequently defeated, and as he lay on the ground, he regained his consciousness and died as Revolver Ocelot. Ocelot's last words to Solid Snake were: "I am Liquid's doppelganger and you are his..." followed by, "You're pretty good", the same phrase Revolver Ocelot said to Solid Snake nine years ago and the same phrase Big Boss said to Ocelot fifty years ago.

Reception and Controversy
Liquid Ocelot has been a well received villain. Edge magazine stated "Kojima has forged a superb villain, far more complete than in MGS2.". However, there is some controversy due to some fans being disappointed that Liquid Ocelot was not in fact Liquid. And there is also some controversy over Liquid Ocelot's handling in the MGS4 Database as it makes vague hints in some articles, suggesting that Liquid's "spirit"/personality was in control, but subsequently contradicting this information by saying it was an act all along in other articles. However, memetically Liquid Ocelot could be argued to be the mental clone of Liquid Snake brought on by Revolver Ocelot's advanced hypnotherapy. By 2014, as far as he was concerned he was now Liquid Snake (apart from flashbacks of his former self in the final battle of MGS4), and therefore he could be said to carry on Liquid Snake's conciousness and will.

The mystery surrounding the truth of Liquid Ocelot has lead to many theories of just who he actually was.

Personality
The personality of Liquid Ocelot is the same as Liquid Snake's personality in MGS2 with some of Revolver Ocelot's personality traits in MGS4. Some view Liquid Ocelot as a fusion/combination of Liquid Snake and Revolver Ocelot.

Behind the Scenes

 * While Revolver Ocelot and Liquid Ocelot are both technically the same person, both have somewhat different voicetones. Revolver Ocelot's voice is more Western-like, while Liquid Ocelot's voice is more menacing and also sounds loud and arrogant (Liquid Snake's personality).
 * In the English version of MGS4, Patric Zimmerman (Revolver Ocelot's English voice in MGS and MGS2) voiced Liquid Ocelot. However, things went differently in the Japanese version of MGS4 because Kōji Totani (Revolver Ocelot's Japanese voice in MGS and MGS2) died in 2006, so Banjo Ginga (Liquid Snake's Japanese voice in MGS and MGS2 and Zero's Japanese voice in MGS3 and MPO) voiced Liquid Ocelot.
 * In the novelization for MGS2, Revolver Ocelot, as he begins to transform into Liquid Ocelot, apparently gives two heartbeats (Raiden notes this by wondering if Ocelot had two hearts). On a related note, apparently Liquid Ocelot also has to be kept at bay by Revolver Ocelot injecting himself with a hypodermic needle.
