Robotonia

Robotonia is a city (that is later found to also be a spaceship) built for robots, situated on the North Pole in Astro Boy.

Founder: The Blue Knight

Leader: Shadow

Location: North Pole

Purpose
Robotonia was planned to be a "safe haven" for robots, following the revolt against robots started in Metro City just days ago before the foundation of the city. Construction was simple and succesful, due to the fact that the robots could effectively work together (something the Blue Knight said humans could never do). The humans thought of Robotonia as a threat, starting a battle in Showdown in Robotonia.
