 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 a large number of Mexican wrestling promotions including working matches on shows promoted by the largest Mexican based promotions such as Lucha Libre AAA World Wide (AAA), Consejo Mundial de Lucha Libre (CMLL), and International Wrestling Revolution Group (IWRG).

La Barredora ("The Sweeper Truck") is a criminal gang based in the Mexican resort city of Acapulco, Guerrero and its surrounding territories.
 The criminal group came into existence during the rapid decentralization of Mexico's drug trafficking organizations and as a split-off group of the Beltrán Leyva Cartel.
 Originally, the Beltrán Leyva cartel operated in the city, but the group no longer has presence in Acapulco.
 After the Mexican military gunned down the top boss of the cartel – Arturo Beltrán Leyva – in December 2009, his brother Héctor Beltrán Leyva took control of one of the factions of the cartel and declared war on Edgar Valdez Villarreal, who had long been the right hand of Arturo.
 Amidst the violence, Valdez Villarreal tried to appoint a successor, but those in Acapulco broke off and formed their own criminal gang: the Independent Cartel of Acapulco.
 Within weeks, however, the group had splittered too, forming a new and rival group known as La Barredora.
 Villarreal Valdez was then captured by the Mexican Federal Police in August 2010, but the violence between the groups for the control of Acapulco continued.
