Wrestling names just depend on the persona someone plays. There is nothing wrong either with someone having a normal name as long as they have a personality, look, nickname, or SOMETHING to make them standout. Like Will Ospreay just uses his real name, but he also has a nickname and look to him as "The Aeriel Assassin." Then there are names as simple as a first name and a term like Jimmy Havoc. We even have more peculiar names like "EVIL," and "Earthquake." It just depends.
