The main antagonist is Gene (Steven Blum/Norio Wakamoto), the current commander of the FOX unit who seeks to establish his own military nation. He is a product of the Successor Project that aimed to artificially create the perfect commander, patterned after The Boss. He is assisted by Lt.

(who is later revealed to be a double agent of the Pentagon sent to tarnish the CIA's reputation) Gene also has a protégé named Elisa (Tara Strong/Saori Goto) who is gifted with extraordinary psychic abilities, implied to be the result of exposure to nuclear fallout during the Kyshtym disaster.

As "Ursula", she works as a member of FOX, while her "Elisa" personality is a medic who takes care of Null and an informant for Snake. Snake meets Elisa, who initially tells Snake that she and Ursula are twin sisters, only to later learn the truth. Two FOX members previously associated with Snake include Null (Larc Spies/Jun Fukuyama), a teenage assassin trained to be the perfect soldier. and Python (Dwight Schultz/Yusaku Yara), a former war buddy of Snake who was previously presumed dead during the Vietnam War. Other characters include Ghost (Brian Cummings/Naoki Tatsuta), an informant who comes into contact with Snake, revealing the existence of ICBMG, the new Metal Gear prototype, Ocelot (Josh Keaton/Takumi Yamazaki), a former Spetsnaz Major who assists Gene from behind-the-scenes, EVA (Vanessa Marshall/Misa Watanabe), a spy for the PLA who assisted Snake in Snake Eater and Raikov (Charlie Schlatter/Kenyu Horiuchi), a GRU Major. Teliko Friedman (Kari Wahlgren/Yūko Nagashima) and Venus (Kathryn Fiore/Rika Komatsu), the heroines from Metal Gear Acid and Metal Gear Acid 2 respectively, can both be added to the player's squad by either: completing certain side-missions or by starting the second playthrough with save data from their respective games.
