Ultimate Fantastic Four X-Men Special #2

Description

The mutant-finding machine supreme — Cerebro — is in the devious hands of the Mad Thinker, who, with her newly-acquired powers, seems impossible to thwart! Even the combined strength of the Fantastic Four and the X-Men mean nothing in this epic conflict. But will a chance for victory come from the most unexpected source imaginable? It’s an ultimate shocker as we conclude this special crossover, begun last month in Ultimate X-Men / Fantastic Four!
