Liquid Snake

Liquid Snake is a fictional character from the Metal Gear franchise. He is the twin brother of series protagonist Solid Snake and the second product of Les Enfants Terribles, a top-secret government project to artificially create soldiers by cloning the legendary soldier Big Boss. He first appears as the main antagonist in the original Metal Gear Solid, where he leads the rogue FOXHOUND unit in a hostile takeover of a nuclear disposal facility in Alaska. The character returns in Metal Gear Solid V: The Phantom Pain as a child mercenary nicknamed the White Mamba with his real name revealed to be Eli.

Metal Gear Solid
Liquid Snake (リキッド・スネーク) was raised in the United Kingdom following his birth, and served as an operative for the British SAS and later became the field commander of FOXHOUND during Metal Gear Solid, leading Revolver Ocelot, Psycho Mantis, Sniper Wolf, Vulcan Raven, Decoy Octopus and the Genome Soldiers. He leads the hostile takeover of Shadow Moses Island, Alaska to acquire Big Boss's remains and use his genetic information to treat the mutations affecting his subordinates, the Genome Army. Liquid harbors a strong resentment towards his twin brother Solid Snake, as he mistakenly believes that Snake received Big Boss's superior genes while he was given only the flawed genes. In reality, it is Liquid who carries superior genes.

Snake first meets Liquid after he is taken captive by the enemy and imprisoned in a medical room. The two brothers battle each other multiple times throughout the story. First, Liquid tries to kill Snake by piloting a Hind D and pursuing him across the Communication Towers but Snake destroys the helicopter with anti-air Stinger missiles. Afterward, Liquid manipulates Snake into activating Metal Gear REX by disguising himself as Master Miller. Snake destroys REX but falls unconscious in the aftermath which allowed Liquid to take his brother to the top of REX's ruins and challenge to a fistfight. Snake prevails but Liquid survives again and pursues Snake in a jeep chase that results in a crash outside the island's facility. Just as he approaches Snake, Liquid suddenly succumbs to the FOXDIE virus that had been injected into his twin brother. Liquid's death leaves Snake in doubt of his own survival, as FOXDIE targets victims based on specific DNA.

Metal Gear Solid 2: Sons of Liberty
Liquid's presence still had an influence. His right arm was transplanted posthumously as a replacement to Revolver Ocelot. This resulted in Liquid's voice and mannerisms to be utilized by Ocelot whenever Solid Snake is nearby, such as when his host is confronted by Snake during the hijacking of Metal Gear RAY from the disguised tanker. The rest of Liquid's body was being kept by an unspecified agency until being stolen by Hal Emmerich to fake Snake's death. Liquid's personality took over Ocelot once again during the climax of Solidus Snake's takeover of the Big Shell with the intent of rebelling against The Patriots. Liquid was the one to send Arsenal Gear crashing into Manhattan.

Metal Gear Solid 4: Guns of the Patriots
Liquid's consciousness seemingly takes over his host's body as Liquid Ocelot. However, Liquid's personality is ultimately revealed to be an elaborate facade by Ocelot made possible through a process of self-hypnosis, in order to trick the Patriots' AIs. The rest of Liquid's remains were used as spare body parts for Big Boss's restoration.

Metal Gear Solid V
Liquid Snake's next official appearance is in a prequel. The youth is a 12-year-old child soldier named Eli (イーライ) who fled from his home in England after learning about his nature as a clone. He becomes an active mercenary in the Angola-Zaire border region in Central Africa where he sets up his own mercenary unit consisting entirely of children, nicknamed the White Mamba (ホワイトマンバ) or "Nyoka ya Mpembe" due to being the only white child soldier in the region.

Venom Snake first encounters Eli in Masa Village after it is taken over by Eli's group. After being subdued, he is taken into Mother Base where the Diamond Dogs staff try to re-educate him and integrate him into normal society along with the other child soldiers. However, Eli resists this treatment and rebels against the Mother Base staff, focusing his hostility on Big Boss's body double who is mistaken for his biological father.

When Eli sneaks into a chopper during Snake's deployment to OKB Zero in Kabul, he catches the attention of the young psychic known as the Third Child, who uses Eli's will to activate Sahelanthropus and attack Snake. After Sahelanthropus is neutralized and transferred to Mother Base, the Third Child infiltrates the place and befriends Eli, giving him a vial containing the English strain of Skull Face's vocal cord parasite. The two plot out an elaborate escape plan which involves helping other child soldiers escape and fixing Sahelanthropus with the assistance of its creator Emmerich. Ultimately, Eli succeeds in reactivating Sahelanthropus and hijacks the Metal Gear from Mother Base, escaping alongside the Third Child and the other child mercenaries.

"Kingdom of the Flies" shows Snake pursuing Eli's group in an unnamed African island surrounded by saltwater, where the English strain of the vocal cord parasite has been spread to prevent access to adults. Snake confronts Eli and a battle ensues between Sahelanthropus and a battalion of Diamond Dogs soldiers. Eli is defeated but Snake is forced to abandon him when he displays signs of infections, as Eli has lost his immunity to the parasites as a result of undergoing puberty. Before Eli can die, the Third Child arrives and uses his psychic powers to remove the parasite within him. The two youths escape just as Diamond Dogs launches a Napalm airstrike to cleanse the island of the parasites. An image of the Manhattan skyline is seen while Eli vows revenge.

Physical appearance
Liquid Snake is almost identical to Solid Snake in terms of facial appearance and physique, with the only difference between them being Liquid's darker skin tone and medium-length blond hair. He has a tattoo of a snake entwined around a sword on his left arm, with concept art also showing a small piercing on his left ear and dog tags around his neck. For most of Metal Gear Solid, Liquid is dressed in a brown trenchcoat but fights shirtless when he confronts Snake at the end of the game. When he disguises himself as Master Miller, he ties his hair in a ponytail and wears a pair of sunglasses, changing the tone of his voice as well. In Metal Gear Solid 2, when Liquid possesses Ocelot, his physical appearance changes as well, exposing the surgically attached right arm and letting his hair loose.

Eli in Metal Gear Solid V wears a wardrobe similar to his older self, consisting of a green jacket with no shirt and shorts. The back of his jacket has a drawing of a pig with an eye patch meant to resemble Big Boss and the phrase "Never Be Game Over" atop of it. Underneath the pig, the kanji 液体人間 (ekitai ningen), which means "liquid person", can be seen. He carries in his belt a conch, a reference to the novel Lord of the Flies.

Casting
In the original Metal Gear Solid, Liquid Snake was voiced by Banjō Ginga in the Japanese version and by Cam Clarke (credited as James Flinders in the PlayStation release) in the English version. Both actors would reprise the role in Metal Gear Solid 2. Stuntman Mark Musashi provided Liquid Snake's motion capture for Metal Gear Solid: The Twin Snakes. The character's young version in Metal Gear Solid V was voiced by Piers Stubbs, who also provided facial capture, while his motion capture was performed by Vincent Giry. Yūtarō Honjō dubbed the character's voice for the Japanese version.

IGN also remarked their rivalry, saying "Few rivalries in games have spanned as massive and confusing a timeline as Solid Snake and Liquid Snake".
