An American who participated in LRRP (Long Range Reconnaissance Patrol) in
Vietnam, and afterwards, exploited his superior skills in SOG (Special
Operations Group), the Green Berets and the Wild Geese. He has completed more
than 70 missions. During the early 70's he was wounded in battle. After this
injury he was diagnosised as sterile (ouch...) US government highly valued his
warfare ability and agreed with Big Boss on a external fertilization program.
This was dubbed the Les Enfant Terrible project during which three clone's of
Big Boss were produced (Solid, Liquid, and Solidus). Despite ethical issues,
this was deemed a necessary step to assure national security during the Cold
War. In the late 80's, Big Boss participated in several regional conflicts and
race liberation wars. He was heralded as a true hero and made the front covers
of popular magazines in many countries. During this time he probably met Frank
yeager and his "sister" Naomi.
In the late 80s, another injury cost him an eye. Big Boss then retired from
the front lines and began to concentrate on military education and training.
The 1990's arrived and he was nominated as general planning commander of the
international special forces squad FOX-HOUND. In the mid-90s Big Boss,
transformed by greed and ambitions of absolute power, managed to take control
of OUTER HEAVEN, (a military fortress nation in Salzburg) and tried to
establish world domination through the country's military powers. Still the
leader of FOX-HOUND, Big Boss sent in a rookie, "Solid Snake" to stop Outer
Heaven in operation Intrude N313. Big Boss used Snake as a guise to fool the
"west" and spread disinformation. Big Boss never imagined Snake would survive
the ordeal. Snake managed to destroy Big Boss's ultimate weapon, Metal Gear,
as well as defeat Big Boss himself and destroy Outer Heaven. With his
ambitions crushed, Big Boss fled to the Middle East.
