Olga Gurlukovich/ Age's (U.S.S. Discovery 30's) (The Big Shell 30's) deceased

The daughter of Sergie Gurlukovich, one of Revolver Ocelot's many apparent allies. She leads her father's army during the tanker incident in 2007, intending to help him achieve his goal of re-establishing Russia as a dominant world power using the new prototype Metal Gear RAY.

However, she is confronted and subdued by Solid Snake, and left unconscious on the deck. Later, when Ocelot showed Sergei his true colours and blew up the tanker, Snake managed to rescue Olga, although she did not know that he was responsible for saving her at the time.
After the incident, in which her father had lost his life, Olga took command of his army and joined the Russian Mafia, which she later discovered was controlled by the Patriots. After she gave birth, her child was taken hostage and used as a means to force Olga into serving the Patriots.

Two years later, Olga appeared as one of the terrorists who took over the Big Shell. However, in reality she was double-crossing her own men in order to do the Patriots' bidding - helping Raiden succeed in his mission. So that Raiden would not find out who she really was, she disguised herself as a ninja and contacted him using the alias "Mr. X."

Olga had originally believed Solid Snake to be responsible for her father's death - however, she learned at the Big Shell that he had saved her life. She then revealed her true identity to Snake, and later Raiden, helping them board Arsenal Gear. Olga was finally killed by Solidus after being forced to divulge her identity to him in a desperate attempt to rescue Raiden his death would also mean the death of her child. She died from a shot to the head.
