X Men/Fantastic Four #2 by Chip Zdarsky

As the dispute over Franklin Richards erupts into an international crisis, both teams descend on Latveria, where Doctor Doom detains the kids and promises to restore Franklin’s fading powers on his terms. Diplomatic maneuvering gives way to a high-stakes battle as Doom deploys power-dampening technology, Doombots, and towering anti-mutant sentinels, forcing uneasy alliances and difficult choices, and leaving Franklin’s future—and the fragile peace between families and nations—more uncertain than ever.
