X-Tinction Agenda

1990

The island nation of Genosha kidnaps members of the X-Men and New Mutants to enslave them using the mutate bonding process. The combined forces of the X-Men, X-Factor, and New Mutants launch a rescue mission that topples the Genoshan government. Cameron Hodge, now a monstrous cyborg, serves as the primary antagonist, and Havok is brainwashed into serving Genosha as a magistrate.
