AJ Styles
It’s been said on WWE programming that AJ Styles had perhaps the best first year in company history, and it would be hard to argue that fact. After a huge debut at the 2016 Royal Rumble, Styles went on to take down John Cena on multiple occasions and win the WWE Championship within his first few months in the company.
Styles’ legacy, of course, extends well beyond that. He was a top champion in New Japan Pro Wrestling and held numerous championships in TNA, including all the company’s top belts. Beyond that, Styles was a leader of the Bullet Club, perhaps the world’s most popular pro wrestling faction, and he is a sure lock to get in the WWE Hall of Fame similar to others that had successful careers elsewhere.
