Ultron is Thermoman's home planet and Superheroes are their greatest export. Ultron is never seen, apart from a few shots of the planet from space (although George once described the gravity and atmospheric pressure to be much greater than Earth), but many references are made to the planet and its unique culture throughout the series. Traditions include the grand ceremony of Betrothal; the great pig juggling ceremony; the time tunnel of tarxis, which re-aligns age hormones; the protocols of Talithos and Zanalar; and the pre-wedding mating ritual. Other less common traditions include the Ultron nose-pinch, which is the sign of true friendship between a male and a female; the sacred oath of allegiance and stance, which features Ultronians standing with their right arms on their hips and their left arms straight across with the hands pointing down; and Chang Ching, a combat to the death, where forfeiting results in being scattered to the corners of the universe in four separate packing cases.
