The storyline behind team is that they are all sons of one of the original Los Capos, Cien Caras and Máscara Año 2000, although only one of the four members have been confirmed as being a blood relative while two others were definitely not.
[2][3] The fact that the team held the championship for a total of 545 days is more a reflection of how infrequent the titles were defended and Los Capos Junior working together than anything else.
[4] This marked the beginning of what would be the longest reign of any IWRG Intercontinental Tag Team Champions, 801 days in total.
[7] Los Junior Dinamitas quickly came to the defense of IWRG, wrestling against Silver King and other AAA representatives such as Alex Koslov, Chessman and Cibernético.
[11] Los Junior Capos did challenge for the AAA World Tag Team Championship on August 19, 2010 but were defeated by champions Silver King and Ultimo Maniaco.
[17] In March 2011 Cien Caras Jr. and Hijo de Máscara Año 2000 participated in Universal Wrestling Entertainment's (UWE) Tag Team Championship tournament.
In the first round they defeated the team of Scorpio Jr. and Zumbido, in the quarter-finals they defeated the team of Los Psycho Circus (Murder Clown and Psycho Clown), but lost their semi-final match to Los Guerreros del Infierno (Atlantis and Último Guerrero).
