Action Comics #396

In a future where Metropolis has outgrown its need for heroes, Superman—diminished and forgotten—struggles to survive on the streets, his powers faded and his legacy reduced to myth. Now, a new kind of streetwise figure emerges, challenging the city's forgotten icon in ways neither expected.

In "The Invaders from Nowhere!", a mysterious threat emerges from the microscopic realm when Krann, a being from a hidden world within Steelman's fortress, abducts the hero and forces him to revive their dying civilization. As Steelman finds himself trapped in a battle not of strength but of survival, he must confront an enemy whose very existence defies the scale of reality.
