1: John Cena
In 2010, after Randy Orton retained the WWE Championship against Wade Barrett, a bizarre stipulation meant the WWE Universe said goodbye to John Cena.
Okay, so Cena wasn't really gone (and in fact main-evented the next pay per view), but for a brief time, the WWE was without Big Match John.
In his absence, came Juan Cena, Cena's alleged cousin, who competed at live events, wearing Cena's distinct Purple and Yellow attire, complete with a matching mask.
After being 're-hired' by the WWE mere weeks after his firing, Cena quietly retired the Juan character.
Whilst Juan never made it to Monday Night RAW, Cena's relation would finally get his big break, appearing recently backstage during an interview with the Lucha House Party.
Who knows when Juan will next appear, though a WrestleMania dream match between Juan and John would put butts in seats.
