The world had been polluted for so many generations that only a few living things are left alive and robots rule the planet.

Robot cities act like their human makers. The few living things left on earth came together and created a circus so to obtain energy from the robot cities as well as cash in on their new found fame.

A large part of the success of the circus is the sideshow acts and Gustoff the cyborg ring leader controls the sideshow acts and is the mastermind behind the art and science of the robot circus but the main tent sideshow is his most successful brainchild yet. Holograms and music spring forth from his magical cane and the young ones love him as much as Bobo; especially his shiny wiggly mustache. Unfortunately Gustoff has the least amount of oraganic material but he often says the only part of him that is left is his heart and that will keep him going another 100 years, at least.
