#3. AJ Styles

AJ Styles' addition to this list might come as a surprise to some, especially since he's been among the best wrestlers in the world for all time. He took a long time to come to WWE, but when he did, he was more ready than ever.
After his debut, the expectation was that Styles would possibly be a midcarder at most, with backstage officials reportedly believing that when signing him. Little did Vince McMahon realize that he had signed the best in-ring talent of this generation.
It took Styles all but 8 months to win his first WWE Championship - a rare feat. Post WrestleMania 32, he was treated like a main eventer and would never look back, beating some of WWE's biggest names and being the face of SmackDown for 2 and a half years - having an incredible year-long reign as WWE Champion between 2017 to 2018.
Styles belongs to an elite list of superstars and after giving The Undertaker his best match in seven years at WrestleMania 36, it's safe to say that Styles is an overachiever.
