As Bonales Aceves held several championships including the NWA World Welterweight Championship, the Mexican National Middleweight Championship and the Mexican National Lightweight Championship.

The NWA World Welterweight Championship is an inactive professional wrestling championship governed by the National Wrestling Alliance (NWA) and most recently promoted by NWA Mexico. The championship was originally created in 1946 by the Mexican promotion Consejo Mundial de Lucha Libre (CMLL). As with all professional wrestling championships, matches for the NWA World Welterweight Championship were not won or lost competitively but by a pre-planned ending to a match, with the outcome determined by the CMLL bookers and match makers. CMLL controlled the championship from 1946 until 1996 and again from 2007 until 2010. From 1996 until 2007 the championship was promoted mainly in Japan, initially as one of eight championships that made up the New Japan Pro-Wrestling (NJPW) J-Crown Championship. After the J-Crown was discontinued the title remained in Japan promoted by the Toryumon federation until 2007 when it returned to Mexico and CMLL. CMLL was a member of the National Wrestling Alliance (NWA) until the late 1980s but chose to keep the championship and the NWA prefix after leaving the NWA.
