2.) Kenny Omega
Kenny Omega is a huge name connected with NJPW. He has developed himself more than any other wrestler and is regarded as the best wrestler in the world. Vince McMahon may have set his eyes on this wrestler who has the ability to wrestle high-quality matches and also has good charisma which is needed in WWE.
A few months earlier, rumours were aplenty that Kenny Omega's NJPW contract is going to expire soon and may WWE could be standing on the line to offer a big money deal to Kenny Omega so as to make the WWE locker room more star-studded.
For "The Cleaner", the Royal Rumble would be the best platform to debut as no other match is so unpredictable as the Rumble. If Kenny Omega arrives at the Royal Rumble and eliminates big stars like Randy Orton, AJ Styles or Shinsuke Nakamura, he could build himself as an even stronger wrestler.
