Colu

The Planet Colu, is considered the center of technological advancement in the universe. Travel to the planet is forbidden by the Coluans and communication with the outside world is kept to the minimum. The planet is theorized to be semi-organic like its inhabitants. When Brainiac 1.0 corrupted Brainiac 5 and set a course for Colu, the Legion of Superheroes warned them.
