#2 "Stone Cold" Steve Austin
Oddly enough, there have been two times where this particular wrestler has changed his name to his ring name, to a certain extent.
Born Steven James Anderson, the future Ringmaster and Texas Rattlesnake would go by many names in his career, but thankfully, he never went to the courts to have his birth certificate read "Stone Cold."

Instead, "Stunning Steve Williams" actually did become Steve Williams after adopting the surname of his stepfather, Ken Williams.
That in itself isn't too strange, as he would later use the Steve Williams name in a professional wrestling capacity.
However, the biggest draw of the 1990s didn't sell out arenas as Steve Williams. The audiences wanted to see Steve Austin.
He was such a mega hit that it became a no-brainer that he would change his name yet again as "Steve Austin" became a brand of sorts, so around 2007, he ceased to be Anderson and Williams and made the transition to fully embrace Austin.
Here's hoping Jim Ross was in attendance to announce that the Austin era had officially begun.
