Solid Snake

He successfully completed multiple solo infiltration missions, including Operation Intrude N313 during the 1995 Outer Heaven Uprising and Operation Intrude F014 in 1999's Zanzibarland Disturbance.
In the Outer Heaven Uprising, he rescued Professor Pettrovich Madnar and destroyed Metal Gear (TX-55) with the aid of Gray Fox, an operative who had previously infiltrated the facility. In Zanzibarland, he fought his former ally Gray Fox who piloted the revised Metal Gear D, and successfully stopped the ambitions of FOXHOUND commander and Outer Heaven ringleader Big Boss, whom he ultimately defeated in combat.
After the conclusion of Operation Intrude F014, he left FOXHOUND to join the CIA as a spy, but retired from his post after only six months. He subsequently moved into hiding in Alaska, where he lived under CIA surveillance.
