*Major Anya Amasova (Russian: Майо́р Аня Aмасова), also known as Agent XXX, is a Soviet intelligence operative originally employed by the KGB and the lover of Sergei Barsov. Portrayed by American actress Barbara Bach, the character first appeared in the 1977 James Bond The Spy Who Loved Me and was also featured in Christopher Wood's accompanying novelisation where she is an agent of Otdyel IV, a department of SMERSH. Anya was subsequently adapted for the 1983-87 tabletop role-playing game, James Bond 007: Role-Playing In Her Majesty's Secret Service.

Anya was depicted as cunning, devious, aloof and fearless. She has strong emotions, but is able to keep them under control, and not to display them very much. She is highly intelligent, adaptable, and may have eidetic memory (as when she discusses blue prints).

She was vengeful and became obsessed with killing James Bond after what he had done to her boyfriend. However, despite this, unfortunately for Sergei, she is also capable of forgiveness and letting go of these grudges as she has shown to have forgiven Bond after she realised Bond actually killed Sergei in self-defence. She is shown to have nerves of steel, since she was completely calm in holding Jaws at gunpoint.

Anya also has a sense of humour, as when she meets Q, she calls him "Major Boothroyd", in order to show she knows who he is... she can also be somewhat playful, given to using pranks to get one up on Bond.*
