Former capital city of the planet Krypton. Later shrunken down into a bottle and removed by the evil Brainiac. The bottle is currently in the possession of Superman and held in the Fortress of Solitude.
Inside the bottle is a futuristic city-scape of roads, buildings and open spaces.
There, headband-wearing Kryptonians enjoy red skies and wide vistas - despite being confined to a bottle.
Their leader is Chancellor Al-On.
