[1] This, and all subsequent IWRG Guerra de Empresas shows featured an eponymous tournament where several wrestling promotions competed directly against each other.
[1][2][3][4] For the 2010 tournament Los Junior Dinamitas (El Hijo del Cien Caras and Máscara Año 2000, Jr.) represented IWRG.
[1] Hardcore wrestling promotion Desastre Total Ultraviolento (DTU) sent the team of Crazy Boy and Joe Líder to represent them and Alianza Universal de Lucha Libre (AULL) tag team champions Los Compadres (Chucho el Roto and Iron Love) rounded out the tournament.
[3] The tournament finals, where Nicho el Millonario and Pimpinela Escarlata defeated Máscara Año 2000 Jr. and Veneno, was not the main event of the show.
Instead of the tournament headlining the third Guerra de Empresas show a multi-man steel cage match was the main event.
IWRG was represented by Los Junior Dinamitas (Cien Caras Jr. and El Hijo de Máscara Año 2000) and the team of Black Terry and Negro Navarro.
Of those seventy wrestlers, six were female, invited specifically for the Guerra de Empresas shows as IWRG does not have a regular women's division.
Violento Jack, representing Desastre Total Ultraviolento is the only wrestler to work all four IWRG Guerra de Empresas shows.
