Captain (Mother Base survivor)

The Captain was a former soldier of the Militaires Sans Frontières' Combat Unit, who helped Big Boss and Kazuhira Miller escape from Mother Base after it was attacked by XOF.

Biograpgy
During XOF's assault on Mother Base, the soldier saved Big Boss and Miller from being shot down, before mysteriously losing consciousness. Eventually coming to, just in time to see Big Boss and Miller departing, the soldier had no time to mourn their lack of fortune as a wormhole unexpectedly opened up above, sucking several people and objects in. The soldier initially attempted to save their war buddy Seth from the wormhole, which resulted in the amputation of the solder's left arm and a seemingly fatal plunge into the ocean. In reality, the soldier survived due to infection by parasitic creatures from making direct contact with the wormhole, but was rendered comatose.

The soldier eventually woke up six months later in a facility belonging to Wardenclyffe Section, a secretive research organization of the United States government. A member of this organization, a man known as Goodluck, gave the soldier a special assignment with the following order: "You don't get to sit this one out. You're already infected with that lifeform I was telling you about." As there wasn't much time before the wormhole opened up, the soldier was unable to get many answers regarding the situation. The soldier then traveled alone to the same parallel world with the codename "Captain" to find a cure for this infection, and to rescue those sucked into the wormhole half a year ago.

Personality
The Captain appeared to have a strong sense of loyalty, deciding to save comrades Big Boss, Kazuhira Miller and Seth from a wormhole, even as Mother Base was falling apart. This loyalty extended to the Captain's new allies in the wasteland, particularly Reeve, Miranda, Nicholas, Dan and Chris. The Captain also appeared shocked, saddened, and hurt after unwittingly being abandoned on Mother Base.

Upon arriving in the Dite wasteland, the Captain appeared to have a great fear of the Wanderers, even in small numbers. When cornered against a wall and a small horde, the Captain seemingly gave up hope and accepted fate, until Reeve provided rescue.

The Captain was proficient in CQC. In 1975, the Captain was armed with a sniper rifle. According to Seth, the Captain was, "as green as grass" by the Ground Zeroes Incident.

Behind the scenes
The Captain is the main protagonist of the spin-off game Metal Gear Survive. The Captain was first seen in a TGS 2016 game play demo for the game. In the beta and final version of the game, the gender of the Captain is chosen by the player. The Captain rarely speaks in the game, only speaking two lines of dialogue in cutscenes, them being "BOOOOSS!" while being sucked into the wormhole to Dite, and "Let's go!" as the Lord of Dust approaches Base Camp.

Depending on the build, the Captain can either perform CQC in the Ground Zeroes variation, or the faster and more powerful variation shown in Metal Gear Solid V: The Phantom Pain.

Similar to Venom Snake, the Captain lost a left arm, which was replaced. While Venom Snake's arm was replaced by a prosthesis, the Captain's arm was regenerated by parasites.

Currently, the Captain is the only protagonist in the series to never use the codename of "Snake."

In the opening of Metal Gear Survive, the Captain's name is listed among the Wandering Mother Base Soldiers from The Phantom Pain. In the bad ending, the Captain is transported to 1984 Afghanistan, waking up in full MSF attire and suffering from memory loss, then picking up a memento photograph before wandering aimlessly into the desert. However, the roar of the Lord of Dust heard shortly afterward, and the "Dead Dogs" nameplate featuring a Wanderer crystal, implies that the Captain will infect the Diamond Dogs upon being rescued.
