#4 Dean Ambrose
Over the course of the build to this historic event, WWE has spoiled many of the entrants in the 50-man Royal Rumble match, as names such as Kurt Angle, Rey Mysterio, and Chris Jericho were all announced for this match in advance.
Therefore, that leaves little room for any surprise returns. However, there is one full-time star that might receive the biggest ovation of the night if he were to return, and that superstar is Dean Ambrose. The Lunatic Fringe is still reportedly injured, but he is expected to make his return to the squared circle soon.

Moreover, rumors suggest that Ambrose would not be making a comeback at the Greatest Royal Rumble event. However, if the most significant surprises are the best-kept secrets, it would be shocking to witness Ambrose inside the squared circle before he was even listed to be fully recovered.
Thus, the best way to fully capitalize on this moment is by booking Ambrose as the last man to enter this match.
