#1. 16-time WWE World Champion John Cena
Or should we say, Juan Cena? The cousin of WWE's Leader of Cenation.
In 2009, John Cena was embroiled in a feud against the group led by Wade Barrett known as The Nexus. Wade Barrett pinned Cena at Hell in a Cell 2010, forcing Cena to join The Nexus.
Charlotte Flair to return and wrestle a CURRENT CHAMPION?
Later, Wade Barrett faced Randy Orton at Survivor Series with Cena as the special guest referee. As a special stipulation, John Cena would be fired if Barrett lost, which he did.
On the following episode of WWE RAW, Cena deliver a heartfelt farewell speech to his adoring fans. Then, he ran out later on to cost Barrett the title in a match with Randy Orton but his future was still uncertain.
While Cena did make his return on RAW the following week, he was contractually obligated to appear at a house show prior to that.
WWE found a way around this when they introduced Juan Cena, The Leader of Cenation's luchador cousin. Juan Cena wore the same attire as his cousin and even performed the Five Knuckle Shuffle and Attitude Adjustment to win the triple-threat against Barrett and The Miz.
Needless to say, Juan Cena was as proficient in the ring as his cousin and won his only match for the WWE, never to be seen again.
