Futurama Episodes

When Fry, Bender and the Planet Express gang attend Roboticon 3003 – the world’s largest robot trade show – the Professor purchases the new “Robot 1-X”, which threatens to render Bender obsolete. Feeling inadequate, Bender returns to MomCorp for an upgrade, but becomes terrified that the procedure will erase his robo-humanity. In desperation, he escapes from the factory and becomes a castaway on a tropical island that seems uninhabited… or is it? Violence ensues.
