Olga Gurlukovich

Olga was the daughter of Sergei, and was with him when he used his mercenary force to attack the transport ship 'Discovery' in his attempt to seize Metal Gear RAY in 2007. Sergei's intention at the time was to use RAY as a superweapon with which to re-establish Russia as a major world power. He boarded the ship with the help of Revolver Ocelot, also known as Shalashaska.

Olga played a role in securing the ship. However, upon completion of her tasks, her father demanded that she leave the ship, shouting 'Need I remind you that you are carrying my grandchild?'. Olga refused to leave however, and shortly after she hung up on her father, she was approached by Solid Snake, who had also boarded the ship so as to procure photographic evidence that the Navy was developing a new Metal Gear and expose it on major websites.

Snake threatened her with his weapon, ordering her to throw her pistol overboard. However, he underestimated her resolve, and was almost struck by a surprise bullet fired from her scout knife (such a weapon suggested that she was in the Spetznaz. Snake and Olga fought, but Snake used tranquiliser darts to knock her out. He left her on the deck, having taken her gun, but she was recovered by her own forces.

Sergei launched his attack on the main hold of the ship, attempting to seize RAY, but was double-crossed by Ocelot, who revealed that he was working for the Patriots. Ocelot shot Sergei and stole the Metal Gear, leaving everyone else on the ship for dead. Snake saved Olga, although she was unconcious at the time and unaware of what was happening.

After this, Olga took command of her father's forces and became a renegade, joining a branch of the Russian Mafia, which was in reality controlled by the Patriots. After she gave birth, her child was taken hostage, and used as a means with which to force Olga into serving the Patriots.

Two years later, the Gurlukovich forces, under Olga, and the Dead Cell group captured the Big Shell, and held President Johnson hostage. Olga was in fact working against her own men as an agent of the Patriots, her mission being to ensure the success of Raiden, a test subject of the S3 plan. So as to accomplish her mission, she was disguised as a ninja at times, so that she could intervene without her cover being blown. Her suit bore a striking similarity to that of Grey Fox, and she too was capable of using a katana to deflect bullets.

After Raiden was held aboard Arsenal Gear, Olga revealed herself to him, setting him free, and telling him of the S3 plan. Raiden, with the help of Solid Snake escaped and was confronted by Solidus Snake. At this point, Olga revealed her true identity to all, including Solidus, determined to help Raiden, since his death would mean the murder of her child by the Patriots. After admitting her wrongs and imploring that Raiden survive, for the sake of her innocent child, she was shot by Solidus.
