Action Comics 242

The Super-Duel in Space is a comic book story, appearing in Action Comics #242. The story features the first appearance of the Coluan villain, Brainiac, as well as the Bottle City of Kandor.


While Lois Lane and Clark Kent are launched into space to report on an experimental spacecraft, the alien Brainiac prepares to shrink cities on Earth to add to his collection. He intends to return them to his decimated homeworld and enlarge them.

Superman fights Brainiac, but finds his technology to be impenetrable. Therefore Superman is forced to allow himself to be shrunken and sneak inside the ship, enlarging Earth's now-shrunken cities.

He also finds a Kryptonian city inside a bottle, which he rescues and brings to the Fortress of Solitude.
