by these kinds of bets. Examples are El Satánico, Negro Casas Perro Aguayo and Villano III (After unmasked, although as a masked wrestler, he has also one of the greatest mask winners in history). An example are the several matches between El Dandy vs El Satánico, two wrestlers engaged in hard-core rivalry over two decades that often went into hair bets. A curious example is the match between Blue Panther and Negro Casas which ended with a tie and both heads were shaved. Apuestas al revés ("Reverse beat"): A controversial variant of beat matches, in this matches two masked wrestlers beat their hairs, they must wear a modified version of their mask with shows their hair, in order to be shaved in case they lose, or the wrestler must remove his/her mask enough to allow the razor to shave his/her hair. This variation was frequent in late 1990s in the Lucha Libre AAA Worldwide shows. These matches are considered by many people as disrespectful to the audience since it's a way for masked wrestlers to not really put on risk their identities. Or a very convenient way for a masked wrestler with a strong streak of beat matches, to lose one without risking anything. The most notorious example of this was Super Muñeco, an extremely successful wrestler in mask vs mask matches (he is the second most successful winner of masks), who won more than 100 beat matches but, "conveniently" or "coincidentally" the only loss in his career was an "apuestas al revés" match against Halloween (wrestler) and got shaved. In another subvariant of the "apuestas al revés", neither the masks nor the hairs of the wrestlers are in the line, but the masks or the hairs of their seconds. Máscara o cabellera contra campeonato ("mask or hair versus title"): if the title challenger loses, they are unmasked or shaved. But if the champion loses, the challenger is crowned the new champion. An example of this occurred in WWE, where Rey Mysterio, a masked luchador, beat the Intercontinental Champion Chris Jericho at The Bash. A different result happened on Raw in 2003, where Kane failed to defeat Triple H for the World Heavyweight Championship, and unmasked per the stipulation. Máscara o cabellera contra retiro ("mask or hair versus career"): if the masked or haired luchador loses, his opponent wins the mask or hair. But if he wins, his opponent must
