Superman Sonderausgabe #6

In "Schlüssel zum Chaos," Superman races against time to save Lois, Steve, and Jimmy from Mongul’s deadly threat, as the Martian Manhunter tries in vain to stop him from delivering the fateful key. With the villain’s plan already in motion, the fate of Metropolis hangs in the balance.

When alien beings abduct her friend Johnny Drew, Supergirl races to stop them from draining Earth’s water—driven by desperation to save their dying planet. With help from Geoff Anderson, Andor, and the enigmatic Nasthalthia Luthor, she must confront a threat that turns the world’s oceans into a battleground.

In "Warworld!", Superman and Supergirl race to stop Mongul from unleashing the full power of the Death Planet, after he steals the key from the Steel Titan. With the fate of the universe hanging in the balance, the duo must survive the deadly trials of Warworld itself—where every step could be their last.

In a cosmic journey beyond known realities, Superman races after Supergirl across the edge of existence, only to be halted by the spectral presence of the Spectre. The line he’s crossed is one even a hero of his power must not breach—though why remains a mystery.
