Every X-Men Team - Ranked From Worst To Best
6. X-Factor
X-Factor has had quite the number of different functions over the years: it started off as a team consisting of the five original X-Men (Cyclops, Beast, Angel, Jean Grey, and Iceman), then it became a team working for the Pentagon, then a detective agency ran by Multiple Man, and now it's "a Krakoan task force that ensures the rules of resurrection are on track".
Such variety combined with the great cast of characters it has enjoyed over the years (the original X-Men, Havok, Quicksilver, Mystique, Multiple Man, Polaris, etc.) make X-Factor a memorable standout among the many X-teams.
Plus, the costumes it has provided - namely Jean Grey's blue & yellow X-Factor costume (which is probably her best) and the fantastic new looks of the new team - are further welcome positives from the group.
