A mysterious figure who appeared on San Hieronymo Peninsula.

Ghost informed Naked Snake of Gene's plot via radio during the San Hieronymo Peninsula Incident. His true identity was Shagohod developer Sokolov.

With the help of The Boss, he escaped Groznyj Grad after using a fake death pill given to him by the CIA, but was later captured by the KGB following Groznyj Grad's collapse.

He was ultimately forced to work on developing Metal Gear RAXA and the Intercontinental Ballistic Metal Gear on San Hieronymo Peninsula. → Prividyenie
