But when the likes of Sabretooth, a cadre of vampires and a threat from an alternate dystopian future wage war against our heroes, it's no big surprise things get a little out of control even for them! Collecting X-FACTOR (1986) #51-59 and ANNUAL #4-5; X-FACTOR: PRISONER OF LOVE; MARVEL FANFARE (1982) #50; and material from FANTASTIC FOUR ANNUAL #23, NEW MUTANTS ANNUAL #6 and X-MEN ANNUAL #14.
