Olga Gurlukovich

Olga Gurlukovich appears in the Tanker chapter as a member of her father's mercenary unit and is the sole boss character in this portion of the game, Metal Gear Solid 2: Sons of Liberty.

She takes over her father's unit after his death in the Tanker chapter, lending her team to the Sons of Liberty terrorist faction. She is shown to be at odds with Revolver Ocelot, blaming him for her father's death. She is actually an unwilling agent for the Patriots, who are holding her child hostage, and assists Raiden as a disguised Cyborg Ninja calling herself Mr. X. By doing so, she is betraying her comrades to ensure her child's safety, a realization that makes her feel guilty. After she reveals herself to Solidus, she is killed with a shot to the head.

Her daughter, Sunny, who was raised by the Patriots, appears in Metal Gear Solid 4: Guns of the Patriots. Sunny has a portrait of her mother hanging in the kitchen area of the Nomad.
