The Sixth King: Wade Barrett
Wade Barrett is a former bare-knuckle fighter, which is how he wound up with a bent nose. When he joined WWE, he was assigned to the NXT show, which was, at the time, not so much a brand as a reality show competition.
He won the NXT season, gaining a WWE contract. However, he would enlist the rest of his NXT rookies into The Nexus and run roughshod on the WWE as part of that faction, most notably defeating John Cena and forcing the latter to join The Nexus.
After the Nexus disbanded, Barrett would go on to form a rather forgettable faction called Corre.
The WWE tried again with Barrett, letting him win the King of the Ring tournament. Much like Booker T had done years prior, he took the crown and scepter as part of his full-time gimmick.
Eventually, Barrett would abandon the gimmick, and WWE has as of yet to crown another. But never say never!
