X-Factor, Part 2
Havok
Polaris

With mutants under siege thanks to the Mutant Registration Act, the members of X-Factor found that, rather than helping emerging mutants, their cover as a mutant investigation squad had actually fueled anti-mutant fears. Dropping that cover was only one of many painful changes X-Factor endured. Finally, their lives came full circle when they were called on to rescue the X-Men from the Shadow King - just as the New X-Men had rescued the original team years earlier!
