X-Force is a fictional Marvel Comics superhero team, one of many spin-offs of the popular X-Men franchise. Conceived by writer/illustrator Rob Liefeld, it formed in The New Mutants #100 (April 1991) and was shortly after featured in its own eponymous series.

X-Force was concocted by illustrator Rob Liefeld, who started penciling The New Mutants in 1989. The (at the time) immense popularity of Liefeld’s visuals allowed him to take over creative control of the book, introducing Cable and several other hard-edged characters in 1990 and 1991. With help from writer Fabian Nicieza, who provided the dialogue for Liefeld’s plots, Liefeld transformed The New Mutants into X-Force in 1991.

In 1997, after this issue under writer John Francis Moore, X-Force broke away from Cable and the X-Men. Moore portrayed X-Force as carefree twentysomethings exploring the open road.
