Grandes Heróis Marvel #19

In "Pesadelo!", the Fantastic Four arrive in Attillan—now floating in the Moon’s "Blue Zone"—to celebrate the birth of Crystal’s daughter with the mutant Mercury. Meanwhile, the aquatic Triton ventures through submerged lunar tunnels and stumbles upon a mysterious crystal artifact, triggering a sudden, violent force that tears the Moon from its orbit.

In the distant cold of Pluto’s orbit, the Shiar Imperial Praetor Gladiador hunts four Skrulls sent to destroy the Fantastic Four—only to crash-land on Earth after their explosion. Disoriented and convinced Earth’s heroes are the real aliens in disguise, he launches a furious assault on the Fantastic Four, forcing a desperate alliance with Spider-Man, Captain America, and the X-Men to prevent a cosmic misunderstanding from turning deadly.
