Para-Medic:

Para-Medic is a FOX support team member who provides Naked Snake with surgical and medical information as well as general information on the local flora and fauna. As Snake Eater is set before the modern use of the word "paramedic", her name instead comes from a portmanteau of "parachute" and "medic."

Para-Medic earned the nickname "Quack" during her employment as a doctor due to her penchant for chatting for long periods of time.

She is generally repulsed by Snake's blatant disregard for selecting suitable plants and animals, which would generally be classed as "people food." This is most apparent when Snake is deciding whether or not he should eat the Spetsnaz guard dogs, The End's parrot, and The Boss' Andalusian horse as a source of food. She also acts in an overprotective manner towards Snake throughout the game.

Para-Medic also loves movies, particularly science fiction and horror titles, and often mentions them to Snake after saving the game or when something reminds her of them. For example, Snake's helmet and breathing apparatus used during the HALO jump immediately preceding the Virtuous Mission remind Para-Medic of the film The Fly. Para-Medic can also be considered a "Japanophile," as she seems completely smitten with the country, its culture and its fads, such as "Kerotan" and "GA-KO." She later created the first paramedic system in Seattle in 1970, and the modern usage of the name supposedly coming from her.

Para-Medic returns in Metal Gear Solid: Portable Ops as Snake's support. Metal Gear Solid 4: Guns of the Patriots reveals that Para-Medic is one of the six founding members of the Patriots and was the one who initiated the Les Enfants Terribles project that led to the creation of Big Boss's clones. She is also revealed to be Dr. Clark, the scientist who was killed byGray Fox prior to the events of Metal Gear Solid. This causes an inconsistency with the English version of Metal Gear Solid, which referred to Dr. Clark as a male (the character had no defined gender in the Japanese version). The Metal Gear Solid 4: Database covers this inconsistency by explaining that Dr. Clark was reclusive and never personally met her staff, leading Naomi to assume she was male.

è la dottoressa nonché esperta di cure mediche alternative a cui Snake fa riferimento per curare le proprie ferite. Tra le altre cose è anche esperta di film e di alimentazione. Nel quarto capitolo della serie si scopre che era un membro dei Patriots, e che diventò la dottoressa Clark; colei che iniziò gli esperimenti genetici e di cui si sente vagamente parlare nel primo Metal Gear Solid. Da Zero ebbe il corpo di Gray Fox, per usarlo come cavia, e fu uccisa proprio da lui su richiesta di Naomi Hunter, per eliminare un membro dei pericolosi Patriots.
