#7 AJ Styles
What, you may ask, is an aging veteran performer such as AJ Styles doing on a list of WWE Superstars who look to dominate 2020?
Whatever he damn well pleases! AJ has proven himself time and time again to be one of the most versatile, amazing, athletic, and reliable pro wrestlers in the industry. From day one he's been shoved on television because he has that intangible 'it' factor that makes people want to tune in to him.
AJ Styles has the rare distinction of having wrestled for WCW, TNA/Impact, Ring of Honor, New Japan Pro Wrestling, and the WWE. He's held the 'big belt' in all but one of those promotions, and we're betting if WCW hadn't been bought out he'd have wound up being their top title holder as well.
Styles is looking to put the exclamation point on his career, and has announced he will retire once his WWE tenure is finished. Look for him to make 2020 truly...phenomenal.
