The surprise appearance of El Hijo del Santo and the attack on Negro Casas resulted in a minor riot in Arena Mexico.
[4] This led to Scorpio Jr. and Bestia teaming with El Hijo del Santo on a regular basis over the following two years, often opposite Negro Casas and various partners.
In late 1998 Bestia Salvaje and Scorpio Jr. turned on El Hijo del Santo during a match, leading to Negro Casas saving his former rival.
[5] Bestia and Scorpio Jr. won the vacant CMLL World Tag Team Championship after defeating the Headhunters, Atlantis and Lizmark and El Satánico and Dr. Wagner Jr. on November 13, 1998 in a tournament.
[6] The tag team championship became a focus of the storyline with El Hijo del Santo and Negro Casas, which lead to a match on February 5, 1999.
Scorpiro, Jr. and Bestia Negra were both older, seasoned veteran wrestlers and neither were actually considered good looking, in fact Scorpio, Jr.'s nickname up until that point had been El Rey Feo ("The Ugly King").
[3] 2000 Shocker was invited to work for New Japan Pro-Wrestling (NJPW) on several occasions and due to his NJPW tours of Japan Scorpio Jr. and Bestia Negra often found themselves without a partner for Trios matches, their solution was to bring in Emilio Charles Jr. to become the fourth Guapo team member, Charles Jr. like his partners used the Guapo name more ironically than factual.

After leaving AAA Scorpio Jr. joined International Wrestling Revolution Group (IWRG) where he won their annual Rey del Ring tournament in 2008.
