Superman Géant #20

In "Duel stellaire," Superman teams up with the reformed Brainiac to confront a planet-sized machine hurtling toward Earth, testing their uneasy alliance in the vast emptiness of space. As the threat grows, Superman is suddenly sent back to Earth—stranded and separated from Brainiac, who now has no way of knowing where he is.

In "Je n'y vois plus," Superman awakens in Metropolis disoriented and blind to the natural disasters tearing across the globe. With Lois Lane, Jimmy Olsen, and Perry White by his side, he must rely on the unexpected help of the reformed Brainiac—whose return to Earth may be the key to stopping a deadly machine on a collision course with Earth.

In "Maître de la pesanteur," the Challengers of the Unknown—Prof. Haley, Ace Morgan, Red Ryan, and Rocky Davis—face a dire crisis when their mission to locate Dr. Charles Brock goes awry, forcing him to build a gravity bomb capable of unraveling gravity across North America. With Red and Rocky captured and the device ticking, Superman and Batman join forces with the remaining Challengers and General Rivers to infiltrate the high-security base where Brock is held. As gravity itself turns against them, the heroes must overcome impossible forces to stop the bomb before it’s too late.
