His real name was Carl W. Greer and he was ranked as an O-3 Captain. He was born in Concord, Massachusetts. His primary military specialty was medical doctor and his secondary military specialty was chaplain's assistant.

Doc was the first member of the G.I. Joe medical team, and possibly the only one with a terminal degree; his M.D. Doc graduated from Harvard Medical School, and completed his residency at Johns Hopkins to become a full medical doctor. He also completed Airborne School, Mountaineering School and the Desert Training Unit. He is an avowed pacifist for practical reasons, in accordance with the Geneva Convention guidelines for battlefield medics.[3] A spiritual man, he devoted himself to alleviating suffering in the world, and admired the G.I. Joe Team's efforts to do the same, by challenging those who would bring about violence and chaos.


Doc was first released as an action figure in 1983.[4][5] The same figure was included in the "Original Team" mail-away set in 1986.[6]

A new version of Doc was released in 2008 as a mail-in exclusive, as part of "Operation: Rescue Doc".[7]


G.I. Joe: A Real American HeroEdit

In the Marvel Comics G.I. Joe series, he first appeared in G.I. Joe: A Real American Hero #11 (May 1983). He saves three other Joes from Destro with a well-aimed snowball, saying he was unable to carry a weapon due to the Geneva Convention. He loses to the man in a fistfight, but manages to secure the antidote needed for several ill Joes. Furthermore, he faces down an armed squad of Cobra soldiers, tricking them into believing they were also sick and trading the 'antidote' for the plutonium that Cobra had taken. What the Cobra personnel inject into themselves is really a tetanus booster shot.[8]

Later, Cobra forces make an attack on Joe headquarters. In the confusion, Doc finds General Flagg dead in the brig; Major Bludd had killed him while escaping.[9] Doc then participates in a raid on a Cobra weapons facility located in Asbury Park, New Jersey.[10] He also flies a recon mission with Wild Bill in the Florida Everglades.[11]

Doc is part of a team investigating Cobra activity in the Gulf of Mexico. During a battle, Doc manually aims a ship's gun while Tripwire fixes and fires it.[12] In issue #40, Doc convinces the military authorities to avoid using nuclear weaponry on another Cobra operation in the Gulf of Mexico. Doc persuades them to use enough conventional bombs to simulate a nuclear explosion without the dangerous radiation. This was planned for by Cobra, who uses the after-effects to raise what would later be Cobra Island.[13] Doc is then part of an aborted raid on the newly formed island.[14]

Later, Doc would join in the hunt for and be impersonated by Zartan, an illusion caster who had ended up deep inside the HQ.[volume & issue needed] He is seen in issue #77, helping to take care of the wounded that resulted from the Cobra civil war.[15]

Doc himself would die in issue #109. He is captured by the Crimson Twins, along with several other Joes, after a mission in Trucial Abysmia.[16] When the Crimson Twins botch an instruction from Cobra Commander and order the prisoners' execution, a S.A.W. Viper steps up to the task. Doc is the first to be slain, followed by several others. The survivors wound the Viper and escape.[17]
