Liquid Snake

Liquid Snake, or simply Liquid, real name Eli, formerly known as White Mamba (Kikongo: "Nyoka ya Mpembe") and McDonell "Master" Miller, was a British-American special operations soldier and spy, former child soldier, and the leader of Special Force Group FOXHOUND during the Shadow Moses Incident.

Liquid was cloned from Big Boss's DNA as part of the Les Enfants Terribles project, along with his brothers Solid Snake and Solidus Snake. He was almost an exact double of Solid Snake in terms of appearance, with the only distinguishable feature being his darker skin tone and fair hair color. Liquid was led to believe that he had been created in order to express Big Boss's recessive genetic traits, and as such, was "inferior" to Solid Snake who supposedly had received Big Boss's dominant genes. Liquid therefore held a strong resentment towards both Solid and Big Boss, wishing to defeat Solid in combat, reclaiming what he felt was his birthright, and thus proving his superiority

Liquid Snake generally displayed an arrogant and extroverted attitude in stark contrast to Solid Snake's calmer and collected personality. He was described as having an "attitude problem" by Kazuhira Miller. He was incredibly resentful and bitter towards Big Boss, believing he had been knowingly chosen by the man to be his "inferior" clone, whereas his brother Solid Snake was endowed with "superior" genes. This drove him to surpass his supposed genetic destiny, and in essence, his father. His hatred was such that when Solid Snake compared him to the then-detained Naomi Hunter regarding his motives, Liquid didn't even deny it. When he was younger, his hatred for Big Boss was intense enough that he reacted violently to even the mere mention of the subject of fathers or even parents, as evidenced by his becoming threatening to one of the soldiers in his squad when the latter relayed to him how his own father was doing with his work in the mines, as well as his instantly attacking Venom Snake when they first met after the latter expressed doubts that his parents named him "White Mamba", and was also severe enough that it overpowered both Skull Face and Volgin's control over Tretij Rebenok (both of whom did so due to mutual hatred of Big Boss).

In addition, he bore hatred towards the Patriots as he had hunted them down for some time and vowed to deal with them in such a manner as to "cause even the reaper's stomach to turn." He was also shown to have a lot of self-loathing to the extent of being suicidal in his younger years, as evidenced by his comment about freeing himself from his cursed heritage when about to fight Venom Snake, his lamentation about his fate being written into his genes, as well as his deeply considering suicide until he was convinced otherwise. This self-loathing aspect was also present to a lesser extent with Liquid Ocelot in 2014, where his doppelganger acknowledged that both himself and Solid Snake were "shadows in the shape of men" and "freaks" who never should have existed in the first place.

Due to his genetic engineering and being endowed with Big Boss's superior soldier genes, Liquid had enhanced strength, speed, durability, knowledge and skills in combat. He was better than the average soldier, easily disarming and pinning one to the ground. Being a commander of a troop of child soldiers who raided several villages, he even held his own against Venom Snake in hand-to-hand combat, dodging and countering his CQC attacks and even evading his gunfire while pinning him to a metal wall with a plastic chair.

As he got older, his fighting and physical prowess had strengthened even more. He became the youngest member of the Special Air Service, excelling at parachuting, rappelling, Scuba diving, free climbing, and use in small arms and military vehicles. Liquid became the squad commander of FOXHOUND, possessed an IQ of 180, and spoke seven languages (English, French, Spanish, Malay, Kikongo, and Arabic). His main language, English, was spoken with a Central London dialect during his childhood, and a Received Pronunciation dialect during adulthood.

In contrast to Solid Snake and Big Boss, Liquid showed an apparent lack of compassion and loyalty to his allies and only seemed to view them as pawns at best. After Solid Snake defeated Psycho Mantis and Sniper Wolf, Liquid thought they were pathetic and foolish for not fighting more effectively. In addition, before Vulcan Raven fought Solid Snake for the final time, Liquid said "[his] existence [was] no longer needed in this world." He also implied that the only reason he even bothered trying to get Big Boss's genes to cure the various Genome Soldiers of their genetic problems was more due to feeling compelled to do so via sharing the same genes and self-interest rather than genuinely caring for their well-being. However, he did seem to possess some skewed sense of pride and honor by letting Solid Snake live to fight him unbound and unarmed in a one-on-one duel (presumably in an attempt to feed his ego).
