X-Force

X-Force is a fictional Marvel Comics superhero team, one of several spin-offs of the popular X-Men franchise. Conceived by writer/illustrator Rob Liefeld, the team was formed in New Mutants, vol. 1 #100 (April 1991) and soon afterwards was featured in its own series.

The group was a new incarnation of the 1980s team, the New Mutants. Led by the mutant Cable, X-Force was more militant and aggressive than the X-Men. X-Force was successful in the early 1990s. The series' popularity waned after Liefeld left, causing Marvel to implement several reforms in the title from 1995 until 2001 with varying degrees of success.

Low sales on the series prompted Marvel to revamp the title in 2001 with a new cast in the form of a group of self-interested young mutants who were gathered together by a corporation to become media stars and used the name X-Force. X-Force, vol. 1 was canceled with #129 and relaunched as X-Statix, which featured the later incarnation of the team. After X-Statix was canceled with #26, Marvel reunited the original X-Force team for a six-issue 2004 miniseries plotted and drawn by Liefeld.

In 2007–2008, during the Messiah Complex crossover, a new version of X-Force was formed that had Wolverine leading a more militaristic black ops branch of the X-Men, forming the basis for a new X-Force series starting February 2008 by writers Craig Kyle and Christopher Yost, plus Clayton Crain as the artist. The series came to a conclusion in September 2010 as part of the Second Coming storyline that ran through various X-titles. The title was then relaunched in October 2010 as Uncanny X-Force with Rick Remender and Jerome Opeña as the creative team and Wolverine, Psylocke, Deadpool, Archangel, Fantomex, and E.V.A. as the initial roster. The series would end at issue #35 in 2012 and be once again relaunched as Uncanny X-Force Volume 2 as part of Marvel NOW!. A concurrent X-Force book, Cable and X-Force, will also be released.
