The original Los Oficiales group was a concept created by AAA owner Antonio Peña that was unveiled in 1996.
[2] At some point between 1997 and 1998 Los Oficiales left AAA and began working for the local promotion in Naucalpan, State of Mexico that would later evolve into International Wrestling Revolution Group (IWRG).
Polizon was a gimmick taken for some time by the wrestler later known as Pierroth II while Xibalba had worked for IWRG under that name for many years before becoming part of the group.
AK-47 had formerly worked as Bombero Infernal and only wrestled as AK-47 for a matter of months before moving on to a new character called "Kraneo" ("Skull").
[6] Often IWRG introduces a new "concept" Trio that fades away after a few months, but this version Los Oficiales sustained their success by repeatedly defending the Trios title against such teams as the tecnico team of Freelance, Kid Tiger and Star Boy, former Oficiales Capitan Muerte, Cyborg and Xibalba and rudos Los Payasos (Coco Verde, Cocochips, Cocolores), successfully taking on all comers, regardless of them being tecnicos or rudos.
[10] On March 3, 2011, Los Oficiales lost the IWRG Intercontinental Trios Championship to Joe Líder, Silver King and Último Gladiador, ending their reign at 886 days.
[12] On October 9, after costing Los Oficiales a match via disqualification, 911 and Fierro turned on Spartans and kicked him out of the group.
[15] On November 1 at Castillo del Terror, another Oficial, Fierro, lost his mask in a twelve-man steel cage match.
[17] On June 15, 2014, 911 and AK-47 defeated Apolo Estrada, Jr. and El Hijo del Diablo to win the IWRG Intercontinental Tag Team Championship.
