John Tolos
Máscaras made his international wrestling debut in 1968 at the Olympic Auditorium in Los Angeles, getting involved in rivalries against the likes of Ernie Ladd, John Tolos, Black Gordman and Goliath. In Mexico City, he unmasked El Halcon in a triangular tournament that included Alfonso Dantés in the 1970s. Owing to the limited spread of news at the time, he repeated the feat in a Japanese ring, winning by submission.
