Xenia Onatopp was a Russian woman who worked for 006. She killed a whole bunch of people in a satellite command center and helped to steal the key for controlling the Goldeneye satellite.
Xenia was definitely one of the stronger women in the Bond series, even if she was a villain. She was good with a gun, good at martial arts and had a unique way of squeezing people to death with her thighs, what a way to go. This last ability of hers also made her pretty cartoonish, which usually decides how entertaining of a Bond character they will be. When it comes to the Bond series, usually the screwier or more outlandish the character is the more memorable and better they are.
