#1 Kazuchika Okada
Kazuchika Okada will undoubtedly be the most interesting person to be seen in WWE. He is the cornerstone of NJPW, and he will ace the WWE World Cup. Okada's fourth reign at 720+ days is the longest in the championship’s history, and he also holds the record for most successful title defences at 12.
Between the ropes, The Rainmaker is an exceptional performer. He thrives at building main-event matches and demonstrates versatility. He is an avant-garde wrestler, and he has created a name for himself on the pro wrestling scene.
A top AEW star just called one of his colleagues 'spoiled' and 'narcissistic' HERE.
If WWE is going to decide the best wrestler in the world without having Okada participating in it, then the entire match is going to be a fluke, and it won't hold much of an importance.
