Para-Medic

Para-Medic, real name Dr. Clark, was a member of FOX in the 1960s who served as a medical adviser to Naked Snake during the Virtuous Mission, Operation Snake Eater, and the San Hieronymo Takeover. Afterwards, she became one of the founding members of the Patriots and joined FOXHOUND as a medical adviser. She stayed with FOXHOUND until she was killed by Gray Fox in 2003.

Early Life
Dr. Clark was a highly regarded physician, who described herself as having a "spotless" reputation, along with being "highly skilled, patient, and good-looking to boot." Due to her tendency of talking too much, she received the nickname "Quack." At some point prior to September 1964, Major Zero recruited Dr. Clark into the CIA.

In 1964, during both the Virtuous Mission and Operation Snake Eater for the FOX unit, Dr. Clark, taking the codename Para-Medic, assisted Naked Snake with details of the environment, such as telling Snake about the different flora and fauna he obtained, which usually ended up with Snake asking how it tasted, a fact that she found quite tiresome after a while. She was also in charge of recording Snake's mission data. After the failure of Virtuous Mission, Para-Medic was threatened to have her medical license revoked if Operation Snake Eater turned out to be a failure. However, she told Snake that her medical license wasn't important to her, and that she volunteered to help Snake anyway.

Being a total movie fanatic, she frequently and enthusiastically talked to Snake (and occasionally Sigint) about them. She actually convinced Snake to go see two movies that she talked about once his mission was complete: Jason and the Argonauts and A Fistful of Dollars. Para-Medic also had a fascination with Japanese culture. In addition, Para-Medic's obsession with horror movies and vampires led Snake to have a vampire-themed nightmare during his imprisonment in the fortress Groznyj Grad, where Snake became a vampire fighting half-breed monsters.

Post-Snake Eater
In 1970, Para-Medic went on to establish the nation's first paramedic system in Seattle, Washington.

In 1970, when Naked Snake was captured during the San Hieronymo Incident, he infiltrated a Red Army communications base on the Peninsula. He was able to reach Para-Medic via radio, and he inquired on what had happened with the FOX unit's rebellion. She explained that Snake and Major Zero had been blamed for the rebellion, and that any members of FOX that didn't join the rebellion under Gene's command were murdered. She also informed him that while Snake had been imprisoned by Gene, Major Zero was in prison himself, courtesy of the Pentagon. She suggested he call Sigint as well, as he was willing to lend a hand to his old friend, from his command center at ARPAnet.

Later, Snake returned to the communications base to contact Para-Medic about a form of tropical malaria that his new comrade Roy Campbell had come down with. Para-Medic diagnosed him over the radio and informed Snake that he would have to infiltrate the nearest hospital in order to find the preventative drugs to save Campbell's life. With the help of Jonathan and his other new recruits, Big Boss was able to save Campbell. Para-Medic later greets Snake when he returns to the USA.

FOXHOUND and the Patriots
Sometime after, Para-Medic was recruited (along with Big Boss, Ocelot, Sigint, and EVA) into the Patriots by Zero. The organization was set up by Zero in an attempt to realize the dying dream of The Boss, who wished to see the world whole again. Under the orders of Zero and now going by her real name of Dr. Clark, she headed the Les Enfants Terribles project to create the "Sons of Big Boss."

In 1999, immediately after Big Boss's Zanzibar Land Uprising was thwarted by Solid Snake, Dr. Clark was the scientist in charge of placing Big Boss into an artificially induced coma, and reviving Gray Fox by encasing him within a cybernetic exoskeleton and using him as a guinea pig for her gene-therapy project. During the next four years, Dr. Clark and her team kept Gray Fox drugged while they experimented on him, the results of which were used in the creation of the Next-Generation Special Forces. In 2003, Dr. Clark was killed by Gray Fox after he was freed by his adopted sister Naomi Hunter. Her death allowed Gray Fox to take revenge for all the years of torment he had endured. Her death was plotted by both EVA and Ocelot as part of a plan to eliminate the members of the Patriots who were allied with Zero.

Trivia

 * Para-Medic' dream of creating a unit of medics that could parachute into battle, when they were needed most, was the origin of her codename.
 * During Operation Snake Eater, Para-Medic told Naked Snake that she loved Japan. Additionally, she had a Japanese assistant during the "Les Enfants Terribles" project, as revealed by EVA in her recounting of the Patriots' history to Solid Snake, during Liquid Ocelot's Insurection.
 * Para-Medic also told Naked Snake that she was fascinated by the prospects of human cloning, and that she saw him as "such an excellent specimen," somewhat foreshadowing her later activities.

Alternative History
''Some of the details of Para-Medic's background were elaborated upon in the official Metal Gear Solid novelization. As such, their canonicity in regards to the Metal Gear series are unconfirmed.''

At some point in the late 1960s, U.S. President Lyndon B. Johnson gave his support for the "Les Enfants Terribles," into which Dr. Clark was recruited. In 1972, she personally oversaw the births of Solid Snake and Liquid Snake, along with the succeeding U.S. President and General Jim Houseman. The President and Houseman both expressed reservations about the project, though Clark attempted to allay their concerns by further explaining the project's goals to them.

Portable Ops recruitment
In Portable Ops, the player is given the option to recruit Para-Medic. This section details how the recruitment takes place:

After Snake manages to get the malaria medication for the San Hieronymo Peninsula, Snake returns to the Communications base to thank Para-Medic for the tip in regards to how to treat malaria. Para-Medic, after accepting the thanks, asks Snake what is truly going on, as she knows that he came back to the Communications base for more than thanks. Snake then admits that he also came to contact her because he needed another favor. He explained that he needed a few of her Paramedic unit members to be dispatched to the San Hieronymo Peninsula, as he needs all the medical help for his unit that he can acquire due to the fact that while several of the personnel have basic medical training, he can't get all of them onto his side, and even if he ended up getting one onto his side, he still can't completely trust their competency level, as some don't have enough medical training and experience to help fix up his soldiers. Para-Medic breaks it to him that there is none available due to the fact that they have all been dispatched to Vietnam, and she doesn't have the authority to issue an order to San Hieronymo Peninsula anyways. She does decide to go to San Hieronymo, however, despite Snake's protests.

A few days later, she arrives at her destination, but is apparently imprisoned in the Hospital, requiring a rescue. A Spy Unit discovers this, and submits a report. After speaking with Roy Campbell, one of the resistance members then escorts her back to the truck.

Behind the Scenes
Dr. Clark was originally implied to be male in the original Metal Gear Solid. In the English version, Naomi repeatedly uses the male pronoun "he" to describe Dr. Clark, while in the Japanese version Naomi only uses the equivalent pronoun kare once. It wasn't until the Metal Gear Solid novelization by Raymond Benson that it was revealed Dr. Clark was a woman. The book also revealed that she was involved in the Les Enfants Terribles project. The Metal Gear Solid 4 Database covers up this inconsistency by explaining that Dr. Clark seldom exposed herself to others and left almost no data behind after her death. As a result, Naomi was convinced that Dr. Clark was a man. However, in the novelization, Solid Snake assumed that Dr. Clark was a male until Naomi corrected him.

A leaked voice casting sheet for Metal Gear Solid 3 stated that Para-Medic used to have a husband, to whom she was divorced as of the time of the game's setting. None of this is mentioned in Para-Medic's Personal Data, nor anywhere else in the game itself, so its canonicity is questionable.

Movies Mentioned
As mentioned previously, Para-Medic was a huge movie fan. Here is a list of the movies that Para-Medic mentioned to Naked Snake during the events of Metal Gear Solid 3:

At one point, Para-Medic asks Snake if he's seen a film called My Mother was a Teenage Spider Queen from Mars. When Snake replies "I can't say that I have", Para-Medic says, "Neither have I." Para-Medic later admits to not paying attention due to Major Zero talking to her at the time.
