#3 The Undertaker returns and confronts A.J. Styles with a 'Haunting' Royal Rumble warning
The Undertaker's last encounter at Crown Jewel ended up pretty disappointingly, and while he may return for a final program at WrestleMania 35, starting his journey from the Royal Rumble would be incredible.
Since the Phenom is rumored to be backstage tonight, there's a possibility that he brings the house down with his supernatural presence to kick-off the Road to WrestleMania.
Moreover, there's a certain superstar who is too popular to ignore a pay-per-view of this magnitude and his name is A.J. Styles.
Considering that the Phenomenal One has been one of the most reliable superstars of the company, a confrontation with the Phenom to explain their intentions for the Royal Rumble match could get the fans excited for 2019.
It makes sense for the former World Champion to make his presence felt, considering that he made his iconic debut at Survivor Series, and being involved in a dream confrontation with the former WWE Champion could be a sight we might never forget.
