X-Force's first leader was the mutant Cable. The group was originally a revamped version of the 1980s team, the New Mutants.
Conceived by writer/illustrator Rob Liefeld, the team first appeared in New Mutants #100 (April 1991) and soon afterwards was featured in its own series called X-Force. The X-Force is a team of superheroes appearing in American comic books published by Marvel Comics, most commonly in association with the X-Men.
