#4 Mr Ass
Billy Gunn achieved his greatest wrestling fame as part of D-Generation X as Mr Ass.
Despite that fact, his was a ludicrous name for a top line superstar.
Gunn was a wrestler who was never blessed with great monikers. Prior to him joining Road Dogg to form the New Age Outlaws, he was known as Rockabilly, a cheap Honky Tonk Man imitation and when he joined Impact Wrestling then known as TNA in the mid 2000s, he was rather unimaginatively christened The Outlaw before being known as Kip James.
Not exactly a name set to strike fear into opponents.
But Mr Ass is on another level entirely. For a man who had ambitions of being a main eventer; an ambition WWE shared for a time considering his King of the Ring 1999 victory and Summerslam co-main event with The Rock, a gimmick centred around him being fixated on his own posterior was peculiar to say the least.
