In appearance, Huon resembles a deformed foetus with an enlarged head. He speaks with an artificial voice which sounds like that of a healthy young man. Huon's limbs are atrophied and useless, and therefore in order to control his Throne Globe, he uses his long, prehensile tongue, which has been described as "insect-like".
King Huon is well over 2,000 years old, and yearns to extend his life no matter the cost. He rules his empire from his Throne Globe in Londra.
