U.S. SEALS 2: The Ultimate Force (1999) [Kamiko/Nikki]: Killed off-screen (exact method unclear) by Damian Chapa. Her body is shown when Michael Worth hears her scream, rushes to the scene and discovers her. (Note: She plays a dual role in this film; the "Nikki" character dies early in the film, but "Kamiko" lives on through the rest of the movie.)
24: Episode 1 (2001) [Flight Attendant]: Killed (along with everybody else on board) in an off-screen explosion when Mia Kirshner activates a bomb on the airplane. We only see a flash of light in the sky as Mia parachutes to safety.
