Gray Fox

Gray Fox, real name, Frank Jaeger, is a character from the Metal Gear games.

Gray 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.

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. He survived his injuries following an intense battle, after which he was forcibly outfitted with a powered exoskeleton and subjected to intensive gene therapy. Fox later confronted Snake as a neutral force during the Shadow Moses Incident, in the guise of the Cyborg Ninja, before dying at the hands of Liquid Snake and Metal Gear REX.

Personality
During his time as the Perfect Soldier Null, his frequent readjustments following each mission deprived him of both his memories and emotions, his only dreams being of waking up to the corpses of his victims lying in front of him, and waiting in vain for his comrades to rescue him. He harbored fatalistic, borderline nihilistic views on life, feeling that it wouldn't truly matter if he spared someone or not as they would die eventually anyway. This belief, as well as his conditioning as the Perfect Soldier, resulted in him developing an intense animosity towards Big Boss after being unable to kill him in battle, and questioning his reasons for living. This aspect eventually resulted in Jaeger renouncing his Null identity altogether when he was defeated by Big Boss.

Abilities
As result of spending majorities of his youth as a child soldier, Gray Fox grew into a skilled and deadly soldier, and the sole member of FOXHOUND who received code name Fox for that reason. Portable Ops. elaborated his lethality back in his days as a child soldier where he used the “frankness of a young boy” upon unsuspecting soldiers before killing them once they lowered their guard with "the ferocity of a hunter".
 * Hand-to-Hand Combat Skills: Gray Fox demonstrated impressive hand-to-hand combat skill as seen in his fight against Snake in the middle of a minefield at Zanzibar Land. After becoming the first cyborg ninja, his skills further enhanced to superhuman level. It should be noted that he has mastered a distinct form of hand-to-hand combat techniques which enable Snake to recognize him through his exoskeleton despite he concealed his face.
 * Marksmanship: As a soldier, Gray Fox is skilled in use of firearms he could reach. The extent of this ability only shown when he fought Big Boss with M10 machine gun as Null.
 * Bladed Weapon Mastery: Gray Fox also skilled when it comes about using bladed weapons, from a simple knife to the most advanced high-frequency sword.
 * Piloting and Driving Skills: Gray Fox has a decent skill in piloting and driving any sort of vehicles as demonstrated from his use of Metal Gear D.
 * Cybernetic Enhancements: After his dying body recovered by the Patriots in secret and used as guinea pig for gene therapy project and other experiments by FOXHOUND's chief medic Dr. Clark, Gray Fox acquired an experimental cybernetic exoskeleton which drastically enhanced his strength and agility to greater superhuman levels. The armor is equipped with an arm cannon that fires explosive energy blasts and a camouflage unit that lets him “cloak” at will, rendering him invisible. However, the poor attachment of the exoskeleton on his nervous system resulted him suffering occasional painful spasms.

WEAPONS & EQUIPMENT

 * Machete: Gray Fox's signature melee weapon as Null. (Portable Ops. only)
 * M10: Gray Fox's firearm as Null (Portable Ops. only)
 * Cyborg Ninja Exoskeleton: Following his defeat at Zanzibar Land, Gray Fox was experimented by Dr. Clark where in the said experiment, he has his crippled body outfitted and put together with experimental blue, brown, and white Cyborg Ninja Exoskeleton. The said exoskeleton is easily recognized with a red lamp in the central portion of the face mask with the eyeslots being to the left and right of the lamp. The armor was also sturdy enough to withstand a direct stomp from Metal Gear REX. The exoskeleton also has following arsenals:
 * Stealth Camouflage: The exoskeleton has built-in Stealth Camouflage technology which allow Gray Fox to be invisible at will.
 * Arm-Mounted Cannon: Gray Fox was able to mount a cannon onto his exoskeleton's right arm which appeared to fire rapid energy bolts strong enough to damage Metal Gear Rex's radome.
 * Radar Dampening Field System: The exoskeleton can emit electromagnetic waves that can disrupt radars, even one as advanced as the Soliton Radar, to short out should its wearer be in close proximity. This trait was best demonstrated when Solid Snake arrived at the Western labs the first time around, after Gray Fox managed to wipe out the soldiers stationed there, as well as during their fight in the actual lab itself.
 * Hi-Frequency Blade: Gray Fox's signature weapon, a blade reinforced by a powerful alternating current and resonating at extremely high vibration frequencies which allow it to cut almost any material on a whim. The concept art suggested that the weapon is collapsible and connected to the exoskeleton which acted as its power source.
