Ringmaster made his first appearance in The Incredible Hulk #3 (September 1962). Ringmaster's hat has the ability to hypnotize people and is the ringmaster of a circus of criminals (though if they serve him of their own will does vary). He is sometimes portrayed as a manipulative mastermind while other times a more pathetic way.
