#10 Prince Puma
Okay, so this one might not be the world's best kept secret, but Prince Puma is definitely worth mentioning.
From Boyle Heights, California, the fictional character of Prince Puma burst into Lucha Underground with a losing effort against Johnny Mundo that proved to be a very rare occurrence before Puma went on to defeat 19 other wrestlers to be crowned the inaugural Lucha Underground Champion.
In Lucha Underground, Puma had a longstanding rivalry with Mil Muertes and, after dropping the belt, formed a team with El Dragon Azteca Jr. and Rey Mysterio Jr and became Trios Champions.
Puma, though, was already a huge name on the indies under his moniker of Ricochet and has since become an even bigger star since signing to WWE where he competes under the same name. The King of Flight, whose real name is Trevor Mann, is actually from Kentucky but resides in Florida.
Also, in his recent feud with Velveteen Dream in NXT, Dream actually wore the Prince Puma pants to face off against Ricochet.
