1997 Cibernético defeated Latin Lover to win the AAA Campeón de Campeones Championship, the top title in the promotion at the time. In 1998 he briefly exchanged the Campeon de Campeones title with longtime rival Perro Aguayo. Cibernético competed in the 1999 Rey de Reyes ("King of Kings") tournament on March 7, 1999. In the first round he defeated stablemate Abismo Negro as well as Dos Caras and Máscara Sagrada to qualify for the finals. In the finals he defeated Octagón, Latin Lover and Electroshock to become the 1999 Rey de Reyes. By late 1999 Los Vipers began fighting amongst themselves as Abismo Negro made a bid to become the leader of the group. The storyline led to the creation of two separate Vipers factions. Cibernético led a group called Los Vipers Primera Clase ("The First Class Vipers") consisting of himself Psicosis II, Histeria, Mosco De La Merced, Maniaco, Mini Psicosis, Mosquito De La Merced and Mini Histeria.
