#2. Rey Mysterio
Rey Mysterio has been unmasked a number of times on WWE TV, most recently in his feud with Andrade, which many fans believed would lead to a hair vs mask match between the two men, even though this is yet to take place.
Despite being unmasked on live TV earlier in his career, Mysterio has continued to wrestle under a mask and has become one of the most famous masked wrestlers in the WWE history.
That being said, Mysterio has also fallen foul to his own fair share of botches throughout his WWE career, the most obvious coming back at Money in the Bank in 2011 when Mysterio was accidentally unmasked by Alberto Del Rio as the star went on to win the breifcase.
Del Rio unmasked Mysterio and then threw him onto another ladder before the entire finish to the match turned into a bit of a mess when Del Rio then fell off his ladder. Mysterio was forced to stay down since his mask had been removed as Del Rio went on to climb the ladder and win the contract.
Of course, none of this involved the time he wrestled sans mask in WCW. But the less said about that, the better.
