In 1983 he returned to Puerto Rico once more and with his Super Médicos partner won the WWC North American Tag Team Championship for the third time on July 10, 1983 when they defeated King Tonga and El Gran Apolo, holding the titles for three months before Tonga and Apolo regained the belts.

The feud continued on January 6, 1984, on another match during which Ayala and Tonga unmasked Super Medico #2 (his manager, Barrabas, covered his face with his jacket).

On January 13, 1984, the two teams had a match in Ponce in which Ayala and Tonga managed to unmask both Super Medics (they left the ring areas with towels around their faces so the fans never saw them).

Super Médico I and Black Gordman won the WWC World Tag Team Championship briefly in December 1984.

[5][6] After the brief tag team run Estrada, still as Super Médico I turned face and won the WWC Puerto Rico Heavyweight Championship on February 10, 1985, beating former partner Black Gordman.

The five tag teams took on the collective face team of The Powers of Pain (The Warlord and The Barbarian), The Rockers (Shawn Michaels and Marty Jannetty), The British Bulldogs (Davey Boy Smith and Dynamite Kid), The Hart Foundation (Bret Hart and Jim Neidhart) and The Young Stallions (Jim Powers and Paul Roma).

The two defeated Los Mercenarios (Cuban Assassin and Jerry Morrow) March 31, 1990 to win the WWC World Tag Team Championship, Senior's fifth and Junior's first title reign.

In September the titles were held up after a brutal match against another masked tag team known as the Texas Hangmen (Killer and Psycho), but Los Super Médico won them back after another brutal match between the two teams on September 22, 1990 only to lose them to the Texas Hangmen a week later.

[5][6] On November 10 that same year Los Super Médicos defeated Eric Embry and Rick Valentine to win the WWC Caribbean Tag Team Championship for the first time.

[12][13] Estrada would retire by 1993, worked as a professional wrestling trainer in Humacao, Puerto Rico and makes special appearances at times.
