X-FACTOR

X-Factor starred the original X-Men after the return of Jean Grey whom was presumed dead. With issue 71, the team shifted as the original 5 returned to the X-Men and Cyclop's brother Havok took on a new team of mutants. The series lasted for 149 issues, after which the series was replaced by Mutant X, following the adventures of Alex Summers. A second ongoing X-Factor series started in 2006, which after 50 issues in the series, turned back to its "original numbering" (adding all the volume 1 issues), and got to the landmark 200th issue of X-factor.
