#3 The Rock
The Rock in the Royal Rumble is a rumour so well known, it's almost stale at this point, but if it does prove to be true, the question is, why would the Rock return to the WWE? The Rock is without a doubt one of the best draws WWE has ever had, and now that he is one of the highest paid actors in the world there is some truth to the fact that he could bring back a ton of viewers back into the product.
Now that the financial answer to that question is answered, let's look at the booking side of things, and you might know by now that The Rock's return to WWE was to put over Roman Reigns at this year's WrestleMania, but since Roman is sadly out of action for some time, that leaves Rocky without a worthy adversary. Well, one such worthy adversary exists in the company, and his name is Brock Lesnar.
Fans hate Lesnar, and they have reason to, and on the other hand, fans love The Rock, it's simple math people WWE putting two of their biggest draws in one of the biggest rematches of all time in the main event would be huge for the company. Furthermore, Rocky is currently an odds on favourite to the match, so could we see him at the event?
#4 Shawn Micheals
Shawn Micheals was probably the best wrestler in the world during his prime, as no one put on a brilliantly crafted match like HBK, and when he retired in 2011 at Wrestlemania 26, many were truly surprised, as HBK had so much more to give to the wrestling industry. But people respected his decision, as he wanted to go out in the prime of his life, and he did.
But last year something unexpected happened, Micheals returned to in-ring action to take on The Undertaker and Kane, it was a move no one saw coming, as the legion of fans screaming at HBK for one more match, were truly surprised when he really did. Should HBK have come out fo retriment to face past their prime legends?
Well, the logical answer is he shouldn't have, but it is his choice at the end of the day, and Micheals chose the joy of wrestling again, and a big fat pay cheque from WWE apparently. That is why it is almost certain that HBK could be in the Royal Rumble match, as many rumours indicate that he could face Daniel Bryan or AJ Styles at WrestleMania in a dream match for the WWE Title, Now could that be the case? Maybe, maybe not, only time will.
#5 Kenny Omega
Kenny Omega is currently the hottest free agent in wrestling, as he lost his IWGP Heavyweight Title at Wrestle Kingdom 13, and he has since announced that he will be leaving NJPW, where will Omega go?
There is two talked about options for "the cleaner", the possibility of joining AEW is intriguing, as Cody Rhodes promotion could offer him the creative freedom he so dearly wants, while an offer from WWE could tempting enough to attract him.
If Omega does decide to go to the WWE could we see him in the Royal Rumble? Well, that might not be possible as his contract with NJPW only expires on the 31st of January while the Royal Rumble takes place on the 27th of this month. While it seems unlikely we also didn't expect AJ freaking Styles to be the third entrant in the 2016 Royal Rumble match, so in wrestling anything possible.
