X-Force is a fictional superhero team appearing in comic books published by Marvel Comics. Created by writer Fabian Nicieza and artist Rob Liefeld, the team first appeared in 1991. X-Force is often depicted as a more aggressive and militant offshoot of the X-Men, focusing on taking direct action against threats to mutantkind. The team typically includes characters like Cable, Deadpool, and Domino, who each bring unique abilities and perspectives. Unlike the X-Men, who often prioritize diplomacy and coexistence, X-Force is known for its willingness to use lethal force when necessary to protect mutants and achieve their goals.
