retire. Carrera contra carrera ("career versus career"): Loser must retire. An example of this occurred in the WWF, where The Ultimate Warrior defeated "Macho Man" Randy Savage at WrestleMania VII. Apuesta por el nombre ("bet for the name"): A rare case, two luchadores with the same or similar name battle among them for the right to use a name or identity. This occurs mostly when the original luchador leaves a wrestling company but the company retains the name and character (often despite the disagreement of the luchador) and the company gives that gimmick to another luchador. If after a while the original owner returns to the company, it's frequent that he or she claims to be the rightful owner of that character, and adopts a similar name, if the conditions allow it, this can be solved in a "lucha de apuesta" where the winner is considered the rightful owner of the character. Sometimes, but not necessarily, it may also result in the loss of the mask for the loser. The most notorious example is the two bouts (with the first match being controversial and thus annulated) in 2010 of Adolfo Tapia (AKA, L.A. Park, a wordplay for "la auténtica parca", i.e. "the autentic parca" in Spanish) against Jesús Alfonso Huerta (AKA. La Parka, La Parka II), in which Tapia (the original Parka) failed to recover the name, and Huerta retained the identity until his death in 2020. Another example is Mr. Niebla from Consejo Mundial de Lucha Libre (Efrén Tiburcio Márquez) who won the name and mask bet against Mr. Niebla from IWRG (Miguel Ángel Guzmán Velázquez). Weight classes Since Lucha Libre has its roots more in Latin American professional wrestling than North American professional wrestling it retains some of the basics of the Latin American version such as more weight classes than professional wrestling in North America post World War II. Like "old school" European (especially British) wrestling, some Japanese wrestling and early 20th-century American wrestling, Lucha Libre has a detailed weight class system patterned after boxing. Each weight class has an official upper limit, but examples of wrestlers who are technically too heavy to hold their title can be found. The following weight classes exist in Lucha Libre, as defined by the "Comisión de Box y Lucha Libre Mexico D.F." (the Mexico City Boxing and Wrestling Commission), the main regulatory body in Mexico: Other characteristics Luchadores are traditionally
