Emperor Arthropodus Supreme is the third and current leader of the Animal Empire, Emperor of Kor, oldest male Supremus and husband of Empress Zemilia. He is also the first Supremus to be born (being born a few minutes before Zemilia). Arthropodus was born 20 years after the events of The Future Of Life On Earth, due to experimenting with Crabus gigantus by the Smokers in an attempt to create a weapon to combat the Animal Empire.
