#2 AJ Styles

Ever since 'the Demon' formed the Balor Club with Luke Gallows & Karl Anderson, the fans have started anticipating & speculating a Bullet Club reunion with 'the Phenomenal One'. Assuming that guys like Cass, Cesaro and Adam Cole join the Balor Club, it seems possible that the next logical step for the faction would be to take over the house that AJ Styles built.
The current WWE Champion is a talented veteran and whether he works as a face or as a heel, his versatility is unquestionable. Joining the Balor Club could bring back the villainous side of 'the Phenomenal One' and would allow the WWE Champion to dominate the blue brand with his a gripping heel persona.
Booking Styles as a phenomenal villainous WWE Champion would not only bring credibility to his character but also bring more star power and prestige to the stable.
The WWE Universe has always anticipated a reunion of the Club and, with the Balor Club coming into full force, it seems inevitable that somewhere down the line they will try and join hands with the 'Prince of Phenomenal'.
