What is the name of the virus in Mission: Impossible 2?

The virus in Mission: Impossible 2 is called Chimera.

Chimera is a fictional, highly dangerous disease agent central to the film’s plot. Biochemist Dr. Vladimir Nekhorvich develops it, while the villain Sean Ambrose seeks to profit from a related cure and the resulting biological threat. Ethan Hunt’s mission is to prevent the virus from being released.

The film also introduces Bellerophon, the fictional treatment designed to cure Chimera. Because the two names are closely linked in the story, viewers sometimes remember the cure rather than the virus when answering this question. Bellerophon is not the pathogen itself.

Mission: Impossible 2 was directed by John Woo and released in 2000. It is the second film in the series and is known for its stylized action, motorcycle sequences, and emphasis on biological warfare. The title “Chimera” also echoes the mythological creature’s name, reinforcing the film’s theme of something unnaturally assembled or dangerous.
