Big Boss, real name John, also known as Naked Snake was a renowned special forces operative and mercenary commander. He founded U.S. Army Special Forces Unit FOXHOUND, along with the mercenary company Militaires Sans Frontières, and was one of the founding members of the Patriots. Big Boss later established the military states of Outer Heaven and Zanzibar Land as bases for his companies, in order to realize his ambitions of creating a nation for soldiers. Considered by some as "The Greatest Warrior of the 20th Century," he earned such monikers as "the Legendary Soldier" and "the Legendary Mercenary," feared in combat by both friend and foe as a hero and a madman.
Having his genetic code used as part of the government project Les Enfants Terribles, Big Boss was the genetic father of Solid Snake, Liquid Snake and Solidus Snake. He was also the mental and physical template for his body double and former subordinate, Venom Snake, with whom he shared the title of "Big Boss."

Naked Snake is featured as a trophy in Super Smash Bros. Brawl.
"As a member of the special-forces unit FOX, Naked Snake assassinated The Boss and ruined the Shagohod, a Soviet nuclear weapon. Years later, he was used to plant the seeds of Les Enfants Terribles, a project designed to create cloned super soldiers. The three Snakes—Liquid, Solid, and Solidus—were thus born. He would then embrace his name, Big Boss, and duel Solid Snake."
