As Ultimatum he earned a contract with Consejo Mundial de Lucha Libre (CMLL) and began working at their wrestling school to hone his skills under the tutelage of Arturo Beristain.

Electroshock was quickly made part of a group called Los Vipers, a Rudo (Heel or "bad guy") group led by Cibernético and that besides Electroshock consisted of Abismo Negro, Psicosis II, Histeria, Mosco de la Merced and Maniaco.

[3] In late 1999 Los Vipers began fighting amongst themselves with Abismo Negro making a bid to take control of the group.

The unity allowed Electroshock and Abismo Negro to focus on regaining the titles, a feat they accomplished on May 7, 2000 defeating Hator and the Panther.

[4] In the fall of 2000 Electroshock travelled to Japan to work for Michinoku Pro Wrestling, specifically to participate in their 2000 Futaritabi Tag Team League tournament.

Over the following couple of years Electroshock separated himself from the other Los Vipers members, choosing to team more often with his brother who worked for AAA under the name Charly Manson.

On June 8, 2001 Electroshock defeated Heavy Metal to win the UWA World Light Heavyweight Championship, a title he would hold for four to five months.

Manson won the match but Lady Apache pleaded with him to not force Electroshock to retire but instead shave her hair off as "payment".

In 2006 Charly Manson, Chessman and Cibernético turned tecnico (Face or "good guys") and formed a group called Los Hell Brothers.

[13] At the 2008 Antonio Peña Memorial Show Konnan, Electroshock, Rellik and Kenzo Suzuki defeated "Team AAA" (Latin Lover, Octagón, La Parka and Super Fly) in a Steel cage elimination match where La Legión won control of AAA (in storyline terms).

[18] At Heroes Inmortales III Charly Manson was scheduled to face Chessman in a Lucha de Apuesta match, but in the days leading up to the event Manson decided to leave AAA, leaving the main event of Heroes Inmortales III up in the air.

[31] On November 14 Electroshock officially announced that he was not part of La Sociedad and urged Silver King and Último Gladiador to leave the group.

[35] After the match both Electroshock and Heavy Metal were attacked by members of La Sociedad, bringing the former rivals together to fight a common enemy.

[36] On June 18 at Triplemanía XIX, Electroshock, Heavy Metal and Joe Líder defeated Silver King, Último Gladiador and Chessman in a Tables, Ladders and Chairs match.

[39] On December 8, 2013, at Guerra de Titanes, Electroshock received his first shot at the AAA Latin American Championship, but was unable to dethrone the defending champion, Blue Demon, Jr.[40] On August 17, 2014, at Triplemanía XXII, Electroshock lost his hair to fellow técnico El Mesías in a six-way steel cage Lucha de Apuestas.

[41] After losing his hair to El Mesías, Electroshock entered a storyline, where he began teasing retirement from professional wrestling.

[47] On June 26 at the press conference, Electroshock makes his return to the AAA company representing himself as part of the Elite League.
