A Thousand Masks), who is credited with introducing the high flying moves of lucha libre to audiences around the world. He achieved international fame as one of the first high-flyers, something he was not considered in Mexico, where he fell under the mat-power category. Style of wrestling Luchadores are traditionally more agile and perform more aerial maneuvers than professional wrestlers in the United States, who more often rely on power and hard strikes to subdue their opponents. The difference in styles is due to the independent evolution of the sport in Mexico beginning in the 1930s and the fact that luchadores in the cruiserweight division (peso semicompleto) are often the most popular wrestlers in Mexican lucha libre. Luchadores execute characteristic high-flying attacks by using the wrestling ring's ropes to catapult themselves towards their opponents, using intricate combinations in rapid-fire succession, and applying complex submission holds. Rings used in lucha libre generally lack the spring supports added to U.S. and Japanese rings; as a result, lucha libre does not emphasize the "flat back" bumping style of other professional wrestling styles. For this same reason, aerial maneuvers are almost always performed on opponents outside the ring, allowing the luchador to break his fall with an acrobatic tumble. Lucha libre has several different weight classes, many catered to smaller agile fighters, who often make their debuts in their mid-teens. This system enables dynamic high-flying luchadores such as Rey Mysterio, Jr., Juventud Guerrera, Super Crazy and Místico, to develop years of experience by their mid-twenties. A number of prominent Japanese wrestlers also started their careers training in Mexican lucha libre before becoming stars in Japan. These include Gran Hamada, Satoru Sayama, Jushin Thunder Liger, and Último Dragón. Lucha libre is also known for its tag team wrestling matches. The teams are often made up of three members, instead of two as is common in the United States. These three-man teams participate in what are called trios matches, for tag team championship belts. Of these three members, one member is designated the captain. A successful fall in a trios match can be achieved by either pinning the captain of the opposing team or by pinning both of the other members. A referee can also stop the match because of "excessive punishment". He can then award the match to the aggressors. Falls often occur simultaneously, which adds to the extremely stylized nature of the action. In
