|EVA, also known as Tatyana, and later known as Big Mama, was a female spy and a femme fatale, who fought alongside Naked Snake during Operation Snake Eater. While posing as a KGB agent, she was actually a spy for the Chinese People's Liberation Army and was on a mission to obtain the Philosophers' Legacy. EVA is the surrogate mother of Solid Snake and Liquid Snake. |
EVA was born in Meridian, Idaho on May 15th, 1936. Since childhood, she had received spy training in The Philosophers Charm School, a joint US-Soviet-Chinese facility, so she could become a "sleeper agent." As a result, she's indistinguishable from any other native-born American. During this time she met The Boss, who was an instructor at the school.
She eventually joined the Chinese People's Liberation Army General Staff Headquarters - Second Division. There, she learned techniques such as "bandit shooting", a horizontal sweep using the China Type 17 pistol.
In 1964, she infiltrated Groznyj Grad, a Soviet military fortress under the command of GRU Colonel Volgin. She did this by posing as the lover of rocket scientist Sokolov, under the alias Tatyana (although Sokolov later revealed that Tatyana was actually Volgin's lover). After Sokolov was captured by Volgin, in order to continue his work on the Shagohod weapon, she pretended to serve the Colonel.
EVA met Naked Snake in Tselinoyarsk, during Operation Snake Eater, as a KGB spy sent by Soviet leader Khrushchev, and was supposedly one of the NSA codebreakers who defected in 1960 along with ADAM. She had been ordered to use her position in Groznyj Grad to supply Snake with information and to acquire intelligence on Shagohod. However, she had actually been sent by the Chinese branch of The Philosophers to steal the Philosophers' Legacy from Colonel Volgin (it is unknown who the real EVA was and what became of him).
After Snake had completed his mission, EVA revealed the truth behind her mission. She had also been ordered to kill anyone who knew about what happened. As she watched Snake sleep on the cabin floor, she made the distinct decision not to kill him, because she had promised The Boss not to.
The microfilm EVA stole later turned out to be a fake. Unbeknownst to her, half of the real Legacy made it back into the hands of the CIA thanks to Ocelot. This blunder cost EVA her job at PLA Intelligence and, according to official records, EVA disappeared in Hanoi during the Vietnam War in 1968.
