Professional wrestlers concealing their identities with masks is no new thing, dating back to the early 1900's when a wrestler named "The Masked Marvel" was involved in the National Wrestling Association would. This was the first recorded appearance of a masked wrestler in America, and despite the mask commonly being connected to the Mexican Lucha Libre style of wrestling, it wasn't until the 1930's did the Lucha wrestling company, the first known as the "Consejo Mundial de Lucha Libre" or the World Wrestling Council. However, over the history, various companies have used the masks in various ways. The first is to hide the identity of the wrestler, mostly for privacy reasons. This was seen in Mexico, as masked wrestlers have tended to take their identity very seriously with specific examples of wrestlers never taking off the mask. An example goes back to El Santo, from the "Empresa Mexicana de Lucha Libre" a wrestling promotion linked to the World Wrestling Council, who refused to remove his mask for 42 years in order to protect his true identity. El Santo only removed his mask well and truly after he had retired. Another reason behind masked wrestlers was it allowed for wrestlers to change characters and gimmicks. Often wrestlers can go through several gimmicks until the promoter rests on one final gimmick. The use of the mask can separate a wrestler from a previously failed gimmick and give the wrestler another chance to win over the crowds. The most famous example of this was Glen Jacobs, who first wrestled under the horrible gimmick of Dr Isaac Yankem, a dentist associated to Jerry the King Lawler. After the gimmick failed, Glen Jacobs was given a mask and reborn as Kane, the kayfabe brother of established wrestler The Undertaker. The gimmick stuck and Glen continues to wrestle under Kane and has gone through various periods both with and without the mask. Glen, or Kane, currently continues to wrestle in the mask and is one of the most famous masked wrestlers still active. The following list is the 10 best masked wrestlers.
