#4 Wade Barrett

When Bad News/Wade Barrett first debuted in the WWE as the leader of the notorious faction The Nexus, he had all it takes to become a future WWE Champion. But his first run with the company has been bittersweet.
Barrett went on to become a five-time Intercontinental Champion and won the King of the Ring tournament, but unfortunately, that's all he could accomplish in the WWE.

Barrett's last appearance for the WWE was at the 4th April 2016 episode of Raw where he and his League of Nations stablemates lost a tag team title match against the New Day. WWE released him from his contract a month later on May 6th, 2016.
It's been almost three years since Barrett left the WWE and a surprise entrance from the Bare Knuckle Brawler would make the crowd go crazy at the Royal Rumble.
