Ultron superheroes take a vow to protect all human life, and the superhero code forbids them injuring another human being. Section nine of the code covers illegal impersonation of a superhero for personal advancement, and for misuse of superpowers for personal gain. Heroes must transform in the bathroom. If a species falls below acceptable standards, they are "permanently excluded from the universe", in the worst possible case. In others, they punish the world that has not done particularly well by sending someone that they hate. George and Arnie quote various rules throughout the series, including "Always set the best possible example", "Never sneeze with your visor closed", "No superhero shall ever lend his name, image or reputation for commercial endorsement of any kind, including Kentucky Fried Chicken", and "Don't drink and fly". Aside from Planet Earth, the Ultrons' closest neighbours are the Zargons, a race of fish-like humanoids. According to George, Miss Zargon, winner of the Miss Universe contest, has "three of the loveliest noses in the galaxy." Several well-known humans on Earth are revealed to hail from Ultron, including Joan Collins, Tom Cruise, Nicole Kidman, and Leonardo da Vinci, who are all in fact Ultronian natives who have found stardom on Earth.
