5 former World Champions who may never win another World Title

#1 Rey Mysterio

Rey Mysterio is widely considered as the greatest cruiserweight in the history of professional wrestling

Arguably the greatest cruiserweight in the history of professional wrestling, Rey Mysterio has paved the path of success for Superstars who lack in size but not skills. Mysterio made his way to the top when guys like him weren't seen as a legitimate threat. Despite this, Mysterio won the both the World Heavyweight Championship and the WWE Championship.

There aren't enough words to describe the legacy of Master of 619. However, just like all good things come to an end, Mysterio might too be at the final stage of his career. However, despite being 44, Mysterio hasn't lost a step in the ring. The Masked Luchador has put forward instant classics in a series of matches against Andrade.

As much as we would like to see the Ultimate Underdog write another Cinderella story, the chances of seeing him as a World Champions are very slim. While Mysterio might find himself in contention of the WWE Championship, his chances of winning it are highly unlikely.
