Mei Foster/Li-Na

Mei Foster is the wife of Robin Foster, the British Ambassador to Thailand, and the major antagonist of Legacy. She is revealed to be Li-Na, a sleeper agent working for North Korea's Office 39, and had been trained for her mission since childhood. Mei uses her position to secure vital components for North Korea's nuclear weapons programme and to orchestrate the assassination of a North Korean general by her husband to further divide North Korea and the West. Although Mei succeeds in her mission, she becomes increasingly frustrated by North Korean politicians who refuse to act on her knowledge of Section 20. When Scott and Stonebridge sabotage the missile programme and escape from her custody, Mei is held responsible and her execution ordered. She escapes with the help of her lover, Kwon, and turns rogue, planning to detonate an improvised nuclear weapon at a United Nations conference in Geneva.
