Roy Campbell: The ex-commander of Fox Hound, Campbell is to Snake what Col.. Troutman is to Rambo, the only man who can track down Snake and lure him out of retirement. Before Liquid Snake's revolt, Campbell rebuilt Fox Hound. Now he's sending Snake in to deal with the traitorous rogues.

Big Boss: Before he turned traitor during the Outer Heaven crisis and was defeated by Snake, Big Boss served as Fox Hound's commander. Believed to be dead, BB will no doubt turn up in MGS.

Masier Miller: Miller served as Fox Hound's survival instructor and is one of the reasons Solid Snake is so darn deadly. He contacts Snake via radio to offer survival hints and strategies.

Solid Snake: A 30-something genius, super spy and bona-fide badass, Snake is your alter ego in MGS. Konami's own PR material cites him as "the man who makes the impossible possible, who can enter any place under any situation." He speak six languages. He's an expert in skydiving, free climbing and scuba diving. After the Outer Heaven and Zanzibar incidents, Snake sought solitude in the Alaskan wilderness. Will he leave retirement for this final mission?

Liquid Snake: The leader of the rogue Fox Hound agents who have taken over Shadow Moses Island, Liquid Snake is Solid Snake's equal. Under the tutelage of Ml5, he learned battle techniques and became fluent in seven languages. He's also one of Fox Hound's new breed of genetically enhanced soldiers.

Revolver Ocelot: A gun nut and spaghetti-western fan, RO is a former KGB agent who joined Fox Hound and became Liquid Snake's right-hand man.

Mei Ling: Ling developed the high-tech communications gear Snake uses on his mission. A student of MIT, she's Snake's flirtatious communications life-line to home base.

Meryl Silverburgh: Campbell's teen niece, Meryl has no combat experience - although she's itchin' for a fight. She's also one of the few genetically enhanced Fox Hound soldiers not to revolt, making her a valuable ally for Snake (as well as a love interest).

Ninja: He's a mystery wrapped up in an enigma encased in a skin of high-tensile alloy and plastic. Is this cyborg ninja a friend or foe? Is he even human? Hell if we know.

Sniper Wolf: You probably won't see much of her since she shoots from outside the screen, but don't treat Sniper Wolf lightly. She's a sniping genius who can aim at targets for more than a week without eating or drinking.

Kenneth Baker:The president of Arms Tech, one of the organizations working on the Metal Gear project. Fox Hound has kidnapped Baker and is forcing him to complete Metal Gear.

Dr. Naomi: The medical chief of Fox Hound, Naomi Hunter conducts gene-therapy experiments on the group's enhanced soldiers.

Decoy Octopus: His previous job as a Hollywood actor and special-effects artist helped Decoy Octopus hone is current abilities as Fox Hound's master of disguise. Expect the unexpected with this guy.

Otacon: Other than his real name, Hal Emmerich, we don't know much about Otacon - other than he's roughly Snake's age and is an American.

Psycho Mantis: This ultra-creepy operative served as a psychic agent for the KGB until the Soviet Union collapsed. He emigrated to the U.S. and worked on serial-killer cases for the FBI - a job that drove him to become a disturbed murderer himself. Fox Hound then hired him as a freelance espionage agent.

Donald Anderson: Anderson is chief of the Defense Advanced Research Projects Agency (DARPA), one of the military contractors building the Metal Gear nuke-hauling robots. Like Kenneth Baker, Anderson is being held hostage by Fox Hound and forced to use Metal Gear to target the White House.

Nastasha Romanenko: Nastasha is a military analyst who specializes in high-tech weapons. Oh, and she apparently loves nuclear weapons and smoking cigarettes. Born in the Russia's Ukraine region, Nastasha now lives in Los Angeles.

Vulcan Raven: An Alaskan native, Vulcan Raven is Fox Hound's heavy-weapons specialist. He can relate to both Solid Snake and Liquid Snake, since - like Raven - the two men have Japanese blood in them.
