 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").Oficiales V4 never won a title, although Cyborg and AK-47 (billed as Kranero) teamed up with Xibalba to win the IWRG Intercontinental Trios Championship – while they were never billed as "Los Oficiales" the team was a mix of V3 and V4.In the spring of 2007 IWRG officials decided to form a new version of Los Oficiales, selecting three IWRG regulars to be repackaged as the masked Oficial 911, Oficial AK-47 and Oficial Fierro.
