Big Boss

In the 1990s, Big Boss returned to the US military as the commander of the newly formed Special Forces unit FOXHOUND.

---

In 1995, the Outer Heaven Uprising prompted FOXHOUND to launch Operation Intrude N313. Contact was lost with Gray Fox, the first agent sent to Outer Heaven, and Big Boss subsequently dispatched Solid Snake, a new recruit. Solid Snake was charged with rescuing Gray Fox and destroying Metal Gear. However, his actions unmasked Big Boss as the mastermind behind Outer Heaven. Big Boss attempted to get rid of Solid Snake personally, but failed and was himself defeated.
