Origin

After the return of Jean Grey (Marvel Girl I), the original X-Men dedicated themselves to the renewal of the mentor Professor Xavier's dream. Much as in their early days they concentrated primarily on finding and training mutants, who were often a danger to themselves and others, in the use of their abilities.


To disguise their own mutations, while simultaneously creating support in the general human community, the five heroes perpetuated a ruse by assuming the identities of non-super-powered humans operating for a corporation known as X-Factor.


After the disbanding of the original team it's mandate and members changed over time. Eventually many of those later members re-tasked themselves as a mutant private detective agency using the brand-name - X-Factor.
