Known as "Tarzan" because of his bodybuilder's physique, Lopez held the Mexican national welterweight championship from 1936 through 1939.

This popularity eventually resulted in López being signed to Empresa Mexicana de la Lucha Libre (EMLL), where he gained his first title, the Mexican National Welterweight Championship, which he won on March 11, 1936.

[1] Although still one of the most popular wrestlers in Mexico, López's career ended early over a monetary dispute with EMLL.

López requested a loan with which he intended to help a friend who desperately needed the money.

When the owners of EMLL refused, an angry López retired from the professional wrestling business and never looked back.
