Return of Jean Grey

in X-Factor (1986) #1

At first a reunion series starring the Original Five X-Men, X-FACTOR expanded into multiple rosters as their agenda shifted. At their debut, X-Factor operated under the ruse of being “mutant hunters,” rounding up young mutants with loose control over their abilities. Jean Grey was resurrected too, leaving Cyclops on the outs with then-wife Madelyne Pryor.

Enter Apocalypse

in X-Factor (1986) #5

X-Factor’s first volume introduced readers to En Sabah Nur, perhaps the world’s oldest mutant and one of the X-Men’s most prominent foes. Read through issue #6 for Apocalypse’s first (full) appearance.

During the MUTANT MASSACRE event, Warren Worthington III, AKA Angel, had his wings irreparably damaged by the Marauders, a team of mercenaries responsible for wiping out the Morlock’s ranks.

in X-Factor (1986) #87

Writer Peter David was a powerhouse on X-FACTOR, establishing many of the relationships and quirks that defined the team. In this now-classic issue, (also mirrored in 2005’s X-FACTOR #13), the team undergoes therapy with one-on-one sessions. Doc Samson guest-stars.

X-Factor Investigations

in X-Factor (2005) #1

After more than half of the world’s mutants wake up without powers, Multiple Man: Jamie Madrox opens a mutant detective agency. The only thing more interesting than X-Factor’s caseload is messy team drama. Ideal for new readers, you’ll want to binge this run.
