X-Men: X-Tinction Agenda

X-Tinction Agenda, a 1990 crossover comic book storyline published by Marvel Comics that ran through Uncanny X-Men and its spin-off titles, X-Factor and New Mutants. "X-Tinction Agenda" not only reunited the X-Men after a prolonged period in which the team had been scattered around the globe (following the events of Uncanny X-Men #246-251), but featured the combined might of the three mutant teams for the first time, in their fight against the mutant-exploiting Genoshan government.
