#1 Edge
Another dream match that many fans want to see is between AJ Styles and Edge. The Rated-R Superstar made his return to WWE at the Royal Rumble pay-per-view. He entered the Men's Royal Rumble match at No. 21, and he eliminated AJ Styles from the match. Later, the rumor mill indicated that Styles suffered an injury while taking a spear from Edge, which forced an early elimination.
If he ends The Undertaker's career at WrestleMania, Styles could then call out Edge for a match, stating that he wants to end his career now. In case he loses, WWE could book an angle where Styles would blame Edge for not being in the main event of WrestleMania. He could argue that had he not made his return at the Royal Rumble, Styles could have won the Rumble match.

Either way, WWE can begin this rivalry and leave it to these two men to take the feud to the next level. Since their WrestleMania rivalries got very personal, the Creative team can allow them to blur the line between kayfabe and reality in this feud as well. A dream match could then take place at the next pay-per-view event of the company.
