El Hijo del Santo is one of El Santo's sons (he had 11 children) and the only one that followed his father's steps as a wrestling and film star.
He debuted in the late 1982, and quickly impressed the Mexican crowds with his mat technique and his aerial maneuvers that remembered his father, at the moment still alive.
He started to shine in the UWA (Universal Wrestling Association) and soon started a rivalry with Negro Casas, defeating him the 28th of October of 1984 in Mexico City for the UWA World Light Heavyweight Title. This was the start of the legendary feud between Negro Casas and El Hijo del Santo. Anyway, Casas wasn’t able to regain that title, and it was a wrestler called Aristotle I who defeated Santo the 14th of July of 1985 for that title. The 1st of September he regained the title, and kept it until the 13th of 1987, date in which Espanto Jr. defeated him in a title match. The 5/29 of 1988 he regained the title, and he vacated it in January of 1991 when he started to wrestle strictly as a welterweight.
Before vacating the UWA Light Heavyweight Title, he also held the UWA World Welterweight Title (won it the 27th of April, 1990 against Charles Lucero) and the WWA World Welterweight Title (won it the 7th of June of 1990 in Tokyo, Japan).
He vacated the WWA title in November 1991, and still defended the UWA title in UWA and EMLL cards, after he lost it the 12th of May, 1992 against Espanto Jr. in Mexico City.
Three days later, the AAA was created by promoter Antonio Peña who broke his relationship with the EMLL, and Santo joined Peña’s crew.
1993 and 1994 ware great years for Santo in the AAA, as he held the WWA World Welterweight Title twice, the National Welterweight Title, the AAA and IWA/AAA World Tag Team titles with Octagon and the National Trios title with Super Muñeco and Angel Azteca.
Santo traveled to Japan again, the 18th of November of 1994, to lose the UWA World Welterweight title to Norio Honaga in Hiroshima. This match had a controversial ending, as Hogana defeated Santo with a low blow and a piledriver, both moves banned from Mexican wrestling.
In Mexico he had great feuds with Heavy Metal (Negro Casas’ brother), Los Gringos Locos (Eddy Guerrero and Love Machine), El Santo Negro and Psicosis. Maybe his best feud was with Guerrero and Machine, but the one that had most intrigue was against Santo Negro. Santo Negro (Black Santo) was a evil Santo. The commentators said that came from Central America and that wanted to destroy Santo. He was none other than Espanto Jr., long time enemy of Santo in the UWA during the 80s. It was a short feud, because the family of El Santo Sr. didn’t like the idea and they sued AAA for the use of the Santo character without their permission.
In 1995 he left AAA for EMLL, now called CMLL, to feud with his worst enemy, Negro Casas, but it wasn’t until late 1996 that he again had gold around his waist again, it was the National Middleweight title who won from Blue Panther.
In December of 1996, Santo shocker the lucha libre world. At that time, Negro Casas turned tecnico and was feuding with rudo Bestia Salvaje. After a match with a Casas’ team victory, Bestia said to Casas that he had a surprise for him. A week later, in a Bestia Salvaje, Scorpio Jr. and Felino vs. Negro Casas, Hector Garza and El Dandy, Santo (then disappeared from the wrestling scene for a month or so), came to the ring dressed as Felino (Casas’ brother) and attacked Negro turning heel!!! This heel turn only could be compared to the Hulk Hogan heel turn, but the difference is that Santo is rudo in Mexico City only (when he wrestles in other places for Promo Azteca or EMLL he’s tecnico) and Hogan is a rudo everywhere.
This heel turn put the Santo/Casas feud on the spotlight again, and it also involved Felino (Casas’ brother) that turned tecnico like his brother.
The 21st of February Santo defeated Rey Misterio Jr. in a tecnico vs. tecnico five stars match under the Promo Azteca promotion, and since Rey was the WWA Welterweight title holder, Santo became champion again.
Later on the year, the 4th of July, Felino upset Santo for the Welterweight title, until Santo regained the title four months later.
Nowadays, Santo is Mexico’s hottest rudo and the man in EMLL, after keeping his silver mask in a mask vs. hair match against Negro Casas and leaving Casas without hair for the second time, as there was a mask vs. hair Hijo del Santo vs. Casas match in 1987.
