Gray Fox, real name Frank Jaeger, was a mercenary and former agent of U.S. Special Forces Unit FOXHOUND. Originally a child soldier, Jaeger was the only operative in FOXHOUND to achieve the codename "Fox," the unit's highest commendation, and was decorated five times.[5] Fox was Solid Snake's comrade-in-arms and friend during the Outer Heaven Uprising, but his loyalty to renegade commander Big Boss forced him into combat with Snake during the Zanzibar Land Disturbance. Left near death following an intense battle, his body was recovered, forcibly outfitted with a powered exoskeleton and subjected to experimental gene therapy. Fox later confronted Snake during the Shadow Moses Incident, in the guise of the Cyborg Ninja, before dying at the hands of Liquid Snake and Metal Gear REX.
