On May 15, 2011 Los Traumas put their masks on the line against the Alianza Universal de Lucha Libre (AULL) Tag Team Championship held by Los Compadres (Chucho el Roto and Iron Love). Los Traumas kept their masks safe as they defeated Los Compadres two falls to one on the UWE 44th Anniversary Show. Trauma II was the third man eliminated in the 2011 Rey del Ring tournament, the earliest elimination for either of the Trauma brothers. Trauma II was one of 16 competitors vying for the vacant IWRG Intercontinental Welterweight Championship, only to be eliminated in the quarter finals by eventual tournament winner Golden Magic. On December 22, 2011, as a part of IWRG's celebration of the Arena Naucalpan 34th Anniversary, Los Traumas found themselves on opposite sides of a Relevos Suicidas match, where the two members of the losing team would be forced to wrestle under Luchas de Apuestas rules. Trauma I teamed up with Oficial AK-47 as they lost to Trauma II and Oficial 911. In the subsequent Luchas de Apuestas match Trauma I defeated AK-47, forcing him to unmask as per lucha libre traditions. Los Traumas once again found themselves on opposite teams during an AULL event when they competed in a four team Relevos Suicidas, for the match Trauma I teamed up with Daga, Trauma II teamed with rival Iron Love with the teams of Chucho el Roto and Judas el Traidor and Flamita and Sadico rounding out the teams. Trauma II and Iron Love lost and were forced to wrestle under Lucha de Apuestas, or bet match, rules which meant that Trauma II had to unmask if he lost. Trauma II defeated Iron Love, who was then forced to have his hair shaved off as a result of the Luchas de Apuestas stipulation. He was one of nine wrestlers competing for the vacant Distrito Federal Welterweight Championship on March 4, 2012 but was eliminated from the Battle Royal as Astro Rey, Jr. won the title. On April 14, 2012 Los Traumas lost the AULL Tag Team Championship to Los Bastardos (Epitafio and Leviathan) on an AULL show in Tlalnepantla de Baz, State of Mexico. On June 17, 2012 Trauma II once again put his mask on the line in a three-way Luchas de Apuestas match against Oficial 911 and Shadow Phoenix. Oficial 911 escaped the match by pinning one of the other two, keeping his mask safe. In the end Trauma II pinned Shadow Phoenix, who was then forced to unmask and reveal his real name as per lucha libre traditions. Both Traumas were part of the 2012 El Castillo del Terror steel cage match, primarily through their developing rivalry with El Ángel. Both brothers escaped the cage without losing their mask. On November 3, 2012 Los Traumas defeated Astro de Plata and Freelance on a Lucha Libre AAA Worldwide (AAA) promoted show, marking the first time Los Traumas worked for Mexico's other major wrestling promotion. On February 17, 2013 Oficial 911 defeated El Ángel and Trauma II by count out, which meant that he would not be forced to put his mask on the line in a subsequent Luchas de Apuestas match, slated for March 3, 2013, while Trauma II and El Ángel would put their mask on the line. The decision was later reversed by the Mexico City wrestling commission due to the fact that 911 won by count out, he was put back in Luchas de Apuestas match. On the night 911 escaped with his mask safe, pining both Trauma II and El Ángel. In the end Trauma II pinned El Ángel even after Los Oficiales attacked both competitors. Following the match El Ángel removed his mask and gave it to Trauma II as a trophy of his victory. On March 31, 2013 Los Traumas competed in IWRG's La Guerra de Familias ("War of the Families") tournament. The team defeated La Familia de Tijuana (Mosco X-Fly and Eterno) in the first round. During the match Trauma I reaggravated an old knee injury and was not allowed to compete in the finals where Trauma II lost to Hijo de Máscara Año 2000 and Cien Caras, Jr. Following the loss Los Junior Dinamitas challenged Trauma I and Negro Navarro to defend their titles a week later. A week later Los Junior Dinamitas wrestled Trauma I and Negro Navarro for the IWRG Intercontinental Tag Team Championship, but lost. On August 9, 2015 Las Traumas and Negro Navarro won the IWRG Intercontinental Trios Championship from Los Piratas (Pirata Mogan, Pirata Morgan Jr. and El Hijo de Pirata Mogan). On April 24, 2016 Trauma II lost the IWRG Heavyweight Championship to Máscara Año 2000 Jr.
