Mr Wonderful is the long-running nickname of investor Kevin O'Leary on the television series Shark Tank, which premiered in the United States in 2009. The name is ironic, contrasting his polite title with his famously blunt rejections of weak pitches and risky deals. Clips of O'Leary using the persona circulated through TV recaps, reaction videos and soundboards, where the phrase became shorthand for cold, profit-first thinking. It remains popular because the character is instantly recognisable even without seeing the show.
