#4 AJ Styles

The story of AJ Styles making it to the WWE is something out of a dream, as no one expected the wrestling legend to be in the WWE. Moreover, no one expected Styles to win the WWE title, and even stand as the top guy in the company today. So what is so shocking about Styles actually winning the Royal Rumble match?
Well, the fact that Styles is taking on Daniel Bryan at the Royal Rumble as well makes it kind of difficult for him to be in two matches on the night, but after Styles' newly revitalised character, it seems like WWE intends making him the top guy in the company.
Also, it seems Daniel Bryan could retain his title, as it's quite early in his reign. On the other hand, AJ Styles would have many options opened up for him. This could take him anywhere, and that might include winning the Royal Rumble.
