5. Kenny Omega

Called by many the best wrestler in the world right now, Omega can do it all; Technical wrestling, stiff martial arts style striking, submissions, and high flying. On top of all of that, he has one of the most compelling personas in the business and looks like he was chiseled out of stone by an ancient Greek sculptor.
Why he hasn't appeared on WWE television: Omega worked for WWE's developmental territory Deep South wrestling from 2005-2006 but has been quite vocal in his criticisms of the company during his tenure. In particular, he had issues with perennial 'problem children' Bill DeMott and Hardcore Holly, who he called out for bullying and general poor behavior. WWE has repeatedly tried to gain his services, and he has repeatedly refused. Omega is under contract with New Japan for the rest of 2018, which means if he does make the unlikely decision to join WWE it won't happen soon.
