Men of Mystery: 10 of the greatest masked wrestlers

#1 El Santo

El Santo is considered the greatest Lucha Libre star, ever.

El Santo--the saint--is a legend all over the world, and with good reason. But he didn't debut as his most famous character. Originally using a variety of gimmicks, he was forced to stop calling himself El Murcielago II after a lawsuit by the original El Murcielago.

Undaunted, he came up with the El Santo persona and never looked back. Kayfabe wise, El Santo NEVER lost a match--though that's not technically true. The most heroic of all babyfaces, El Santo never broke any rules and always won with fair play.

El Santo is known for never, ever taking off his mask, even among close friends and other wrestlers. He even wore his mask to restaurants and social functions in his personal life!

Santo starred in dozens of films, such as El Santo vs. the Vampire Women, a cult classic. He has also been immortalized in comic books, cartoons, action figures, and video games. As the no-questions-asked greatest Lucha Libre star of all time, he holds a unique place in wrestling culture and Mexican history.

Here's El Santo taking on longtime rival and sometimes ally, the Blue Demon--a legend in his own right.
