#4 Several Royal Rumble Records
Reigns is named a few times in the Royal Rumble statistics and trivia, namely for having won the 2015 match and usurping Kane's record of eliminations in a single battle royal in 2014 with 12.
It might not seem like it, but there are still a number of other things Reigns can do with just the Royal Rumble itself.
A top AEW star just called one of his colleagues 'spoiled' and 'narcissistic' HERE.
For instance, he can go the distance from the #1 spot to the end and win, being one of only two people to have done that (the other two being Shawn Michaels in 1995 and Chris Benoit in 2004).
If he does this, Reigns can overtake the record for the longest time in a Royal Rumble once he moves past the 1:02:12 mark from Rey Mysterio in 2006, and even eventually the cumulative total time which currently stands at Chris Jericho's near 5 hour mark.
He can also surpass Kane and Shawn Michaels with over 44 total eliminations to get the record for most Superstars ever tossed out by the same person over the course of multiple matches.
Reigns also can very easily in 2018 be one of only a handful of wrestlers who have won more than a single Royal Rumble, and if he wins it a third time, he'll be tied with Steve Austin for the most wins ever.
