Trauma I is a Mexican luchador enmascarado, or masked professional wrestler, working on the Mexican independent circuit and as a freelance wrestler for promotions such as International Wrestling Revolution Group (IWRG), portraying a tecnico wrestling character. Trauma I's real name is not a matter of public record, as is often the case with masked wrestlers in Mexico where their private lives are kept a secret from the wrestling fans. Trauma I is a second-generation wrestler, the son of Miguel Calderón Navarro, better known under his ring name Negro Navarro. He is the younger brother of Trauma II, who he regularly teams up with under the name Los Traumas. Trauma I is a freelance wrestler and thus is not exclusively working for one specific professional wrestling promotion but has worked for many Mexican wrestling promotions including working matches on shows promoted by the largest Mexican based promotions such as Lucha Libre AAA Worldwide (AAA), Consejo Mundial de Lucha Libre (CMLL), and International Wrestling Revolution Group (IWRG).

Rebelión de los Juniors (2012) was the first annual professional wrestling major event under that name produced by Mexican professional wrestling promotion International Wrestling Revolution Group (IWRG). The show took place on March 27, 2011 in Arena Naucalpan, Naucalpan, State of Mexico, Mexico, IWRG's main venue. The main event focused on the newly created IWRG Junior de Juniors Championship with the inaugural champion El Hijo de Pirata Morgan put his championship on the line against El Hijo de L.A. Park and Trauma I. The two challengers both risked their mask on the outcome of the match and would have been forced to unmask if they were defeated as per Lucha de Apuestas or "Bet match" rules. The undercard featured an additional Luchas de Apuetas match, where the losing team of a Relevos Suicidas, losing team advances tag team match between the teams of Comando Negro/Multifacético and El Pollo Asesino/Eterno would be forced to wrestle each other.
