The ringmaster was the host of the Psychic Circus. When appearing in the ring, he spoke in rhymes in a sort of rap.
He accepted the fact that people got killed in the circus ring just so he could stay alive, even though his friend Morgana did not like it. He saw the deaths of Nord the Vandal and Whizz Kid. When all the entertainment was finished, the chief clown and the robot clowns forced him and Morgana into two large wicker baskets so the Gods of Ragnarok would be entertained by a magic disappearing act.
The clowns closed the wicker baskets and when they opened them both, the ringmaster and Morgana had vanished forever. Only the ringmaster's shiny red top-hat was left behind. (TV: The Greatest Show in the Galaxy)
