Fantastic Four #111/112

When a global blackout plunges the world into darkness, the Fantastic Four race to the North Pole to investigate a towering, mysterious crystal structure that may be behind the crisis. As they confront the impossible scale and strange energy of the formation, they realize this isn't just a natural anomaly—it's something far more enigmatic, and possibly sentient.

In "La possession de Franklin Richards!", the young Franklin Richards becomes an unexpected focal point when Nicholas Scratch, still imprisoned in the Dark Realm, attempts a desperate escape by manipulating a portal in the Baxter Building. With the help of Gabriel the Devil-Hunter and Agatha Harkness, the Fantastic Four must race to protect Franklin before the forces of darkness fully claim him.
