4. AJ Styles As Surprise Entrant
Latest reports suggest that former TNA World Heavyweight Champion AJ Styles might make his official WWE debut on next week’s Raw, which is the post-Royal Rumble episode of Raw.
However, Styles arriving in WWE would make more impact if it happens during the Royal Rumble 2016 match, rather than making a pre-announced debut (as reports say WWE might be producing vignettes for his debut).
With the Royal Rumble match lacking many big names this year, AJ Styles would be a good addition and surprise for the match.
