1. William Regal
Back in 2008, William Regal received a huge push that should have ended with him become the first ever WWE champion from the United Kingdom. The push started when he became the general manager of Monday Night Raw. It was followed up by being crowned as the King of the Ring and dubbing himself as the most powerful entity in the entire WWE.
However, it was halted when he lost a Loser Leaves Raw match against Mr. Kennedy. In reality, Regal was suspended for 60 days after violating the WWE Wellness Policy for the second time. When he returned, he was never given another push at the top.

Nevertheless, Regal is a future WWE Hall of Famer. He is a four-time European champion, a two-time Intercontinental champion, a five-time Hardcore champion, a four-time Tag Team champion, and former King of the Ring. Regal is currently the general manager of NXT, as well as the Director of Talent Development and Head Coach of Global Recruiting.
