(a.k.a. 006, a.k.a. Janus): Former British double-0 agent and friend of James Bond (Pierce Brosnan) turned duplicitous traitor, portrayed by Sean Bean in GoldenEye. The son of Lienz Cossacks who were betrayed by the British after World War II, Trevelyan has sworn revenge on the country that was responsible for his parents’ suicide. Introduced as 006 and shown as Bond’s comrade in a dangerous mission to destroy a Soviet chemical weapons depot, he’s apparently killed by Colonel Ourumov (Gottfried John) before Bond obliterates the plant.
The story picks up nine years later as Bond investigates a mysterious Russian crime figure, Janus, who is intent on destroying England with an electromagnetic pulse generated by a commandeered satellite. Janus, as Bond discovers in a graveyard of junked Communist-era statuary, is really Alec Trevelyan, who faked his death and became the head of a major Russian crime syndicate. Another reason for Trevelyan to seek revenge: Bond changed the timer on the demolition charges set at the chemical facility, so although Alec wasn’t really killed by Ourumov, his face was badly scarred by the chemical explosion.
