Gray Fox

Gray Fox was one of the best agents FOXHOUND had, he was also Solid Snake's best friend.

The first mission of his we know is that he was the original choice Big Boss made to send into Outer Heaven, before he was taken hostage. He was then rescued by Solid Snake, and told Snake of the existance of Metal Gear.

Later, he quit FOXHOUND and joined Big Boss when he made Zanzibar Land. Fox commanded the army that Big Boss had put together. Then, Fox and Solid Snake fought in the middle of a Mine Field... They were still friends, just two Soldiers doing there job. Eventually Snake defeated Fox.

The Government then decided to revive Fox and use him to test the Genome Therapy which they would need in order to create the Genome Army. After a series of brutal and horrifying tests, they eventually turned him into a Cyborg and created Cyborg Ninja. Ninja then escaped to find Snake so that they could once again battle to the death. He headed to Shadow Moses and found Snake there. They fought and once again Snake won, before Ninja had a slight break down. He vanished. He appeared once again when Snake was fighting Metal Gear REX, and helped Snake defeat REX, and also gave up his life for the cause.
