FOXHOUND/Bio & Battles

High-Tech Special Forces Unit FOXHOUND is an elite black ops unit of the United States Army founded by the legendary soldier Big Boss, which features heavily in the Metal Gear series. FOXHOUND specializes in solo infiltration missions of a highly sensitive nature. Operatives of FOXHOUND were highly experienced before being selected, and were trained heavily in survival and operational skills in order to succeed in their missions.

The concept of FOXHOUND began in a resistance group founded by Big Boss against the renegade FOX Unit. Big Boss established FOXHOUND officially as a unit of the US Army in 1971.

In 1995, FOXHOUND rookie Solid Snake was deployed on a mission in the military nation of Outer Heaven, with the objectives of rescuing his comrade Gray Fox and eliminating a new nuclear weapon named Metal Gear. Snake succeeded, and he encountered the leader of Outer Heaven, who identified himself as Big Boss. Snake defeated him in battle.

Following Big Boss's betrayal, Colonel Roy Campbell took command of FOXHOUND. During the Zanzibar Land Disturbance, Big Boss was revealed to be alive and in command of the Zanzibar forces, alongside Gray Fox, who had defected. Solid Snake succeed in defusing the incident, and Big Boss was presumed dead. Both Snake and Campbell retired after the incident.

In 2000, a new operative named Liquid Snake became FOXHOUND's commander. Under Liquid, the unit was reorganized as a smaller, counter-terrorism unit with a new focus on cutting-edge technology, specifically genetic manipulation. In 2005, Liquid Snake and FOXHOUND revolted against the US government. Calling themselves the "sons of Big Boss", they seized control of the Shadow Moses facility, threatening to launch a nuclear weapon if their demands were not met. Solid Snake was called out of retirement to diffuse the situation, which he succeeded in doing, killing many of FOXHOUND's members in the process. FOXHOUND was officially disbanded after the incident.
