Big Boss is the codename of the legendary soldier who founded the special forces unit FOXHOUND. He also served as the founder of the private military contractor Outer Heaven in South Africa and later founded the nation of Zanzibar Land in Central Asia.
Big Boss was considered by some to be the "greatest soldier in the 20th century" and a brilliant military leader. He was hailed as a war hero by admirers and feared as a tyrant by his enemies. As a result of the Les Enfants Terribles project, he is the "father" of Solid Snake (his subordinate and later nemesis), Liquid Snake and Solidus Snake.
Prior to earning the codename Big Boss, he served as a field operative for the FOX unit under the codename of Naked Snake during the Cold War. The official MGS database revealed his real name to be John, but he is being called Jack by close acquaintances.
