#3 Superstar that will make up the final four of the Men's Royal Rumble Match - AJ Styles
The Phenomenal One has defended the WWE Championship at three of the last four Royal Rumbles (2017-2019). He debuted in the 2016 Royal Rumble and was eliminated from last year's bout by Edge. Simply put, he hasn't had many chances to show off in these types of matches.
It's for that reason that AJ Styles could very well be one of the last men standing in this year's contest. He has the towering Omos by his side, who could be used to stave off his elimination for the duration he is in the Royal Rumble.
Styles is also one of the top stars in WWE, so he needs to be around until the very end. If he's supposed to be in the conversation with Seth Rollins, Reigns and McIntyre, he deserves a spot in the 2021 final four. There could also be the scenario where Edge returns from injury during the Royal Rumble and eliminates Styles again.
That could set up a potential match at the Show of Shows for both men. The Phenomenal One has stated a few times that he'd like to face the Rated R Superstar on the Grandest Stage of Them All.
McIntyre has already dispatched of Styles in a title match but that doesn't automatically mean that the Phenomenal One is or isn't winning. Lasting until the final four combatants of a Royal Rumble, however, is definitely in the cards for Styles.
