Solid Snake (ソリッド・スネーク?) is a fictional character and the main protagonist of Konami's Metal Gear series of stealth video games. Created by Hideo Kojima, Metal Gear is Konami's main franchise[4] and has sold approximately 26.5 million units as of February 2009.[5] Introduced in the first game of the series, Metal Gear (MG) (1987), Snake has appeared in the majority of subsequent games and spin-offs. Japanese voice actor Akio Ōtsuka voices Snake in Japanese, while actor and screenwriter David Hayter provides the English voice of the character. In his guest appearance in Ape Escape 3, he is voiced in English by Peter Lurie.
Solid Snake is a combination spy, special operations agent and mercenary of FOXHOUND, a fictional black operations and espionage unit. He is repeatedly tasked with disarming and destroying the latest incarnation of Metal Gear, a bipedal nuclear weapon-armed mecha. Controlled by the player, Solid Snake must act alone (or with the help of allies he meets during missions), supported via radio by commanding officers and specialists.

Sam Fisher was a member of Third Echelon, a top-secret sub-branch within the National Security Agency (NSA). He is 178 cm (5 feet 10 inches) tall, weighs 77 kg (170 pounds)[1], and has brown[2] (or black, slightly graying[3]) hair and green eyes. He was the first person to be recruited as a field operative of the "Splinter Cell" program for Third Echelon. Fisher is an expert in the art of stealth and concealment, in which he is trained in various techniques and tactics. He is also highly trained in the Israeli hand-to-hand combat system of Krav Maga. In Tom Clancy's Splinter Cell: Conviction, he utilized the Center Axis Relock, a gun-fighting technique used in close quarters combat. He prefers to work alone in the field. When not on assignment or at Fort Meade, Fisher resided in a townhouse in Towson, Maryland.
Fisher was born on August 8, 1957[4] in Towson, Maryland[5]. While not much is known about his early life, it is known that Fisher attended a military boarding school shortly after his parents died when he was a child. He later spent two years as a Political Science major. While Fisher was stationed at an U.S. Air Force Base in Germany during the 1980s, he met and later married Regan Burns in 1984. They had one daughter together, Sarah (born 31 May 1985)[6]. Fisher and Regan later divorced and she had Sarah's surname changed. Regan died from ovarian cancer sometime in 1999[7] and Sarah was "killed" by a "drunk driver" in September 2007. However, it was established that the death of his daughter was no accident. After learning this, Fisher attempts to uncover why his daughter was murdered, and what connections it has to Third Echelon, which has become bogged down with red tape to the point of ineffectiveness and corruption. It is soon revealed that Sarah is alive and was used as leverage to frame Sam for an unsuccessful coup against the U.S. President.
Sam's direct supervisor and handler was Colonel Irving Lambert, USA (Ret), who coordinated intelligence and objective updates with Fisher during his missions. In addition to being supported by Lambert, Sam was also accompanied and supported on operations by NSA employees Vernon 'Junior' Wilkes (deceased), Anna Grímsdóttir, Frances Coen and William Redding (introduced in Chaos Theory). One of his aides, Dermot Paul ("D.P.") Brunton (introduced in Pandora Tomorrow), became the head of SHADOWNET Operations, a black-ops group within Third Echelon which uses teams of operatives.
Fisher has conducted operations in Canada, the Democratic Republic of Congo, China, Iceland, Israel, East Timor, Indonesia, Japan, Kyrgyzstan, Russia, Ukraine, Turkey, Azerbaijan, Iran, North and South Korea, Mexico, Panama, Peru, Myanmar, Serbia, the Republic of Georgia, and France in order to complete his missions. He has also conducted operations inside the United States, places such as LAX International Airport in Los Angeles, California, New York City, New Orleans, Ellsworth Federal Penitentiary in Kansas and the CIA headquarters in Langley, Virginia.
Ubisoft's lead character artist Martin Caya established in early interviews about the game that during his career Fisher had served in Afghanistan, where he had an experience in which he was forced to hide under dead bodies in order to avoid being killed. Caya also established that Fisher had served in East Germany and in "other Soviet satellite countries leading up to the collapse of the USSR."
