Doctor X

Professional wrestling career

Consejo Mundial de Lucha Libre (1996–2011)

Early years (1996–2005) Valencia began his professional wrestling career in 1995 after training under Rafael Salamanca, La Cobra and Scorpio (Sr.); he later received additional training from Memo Díaz and El Satánico. Initially, he worked as Dr. O'Borman Jr., paying the original Dr. O'Borman for the use of the name. By the end of the 1990s, he began working regularly for Consejo Mundial de Lucha Libre (CMLL). Over the following years, he kept working low card matches, slowly establishing a name for himself. In early 2003, Doctor X began a storyline feud with Tigre Blanco, whom he defeated on 11 March to win the Mexican National Welterweight Championship, which he held for over two years.

Pandilla Guerrera (2005–2007) In early 2005, the wrestling group Los Guerreros del Infierno created an affiliated group of low to mid-carders called Pandilla Guerrera (Spanish for "Gang of Warriors"), including Doctor X, Nitro, Sangre Azteca, Hooligan and several others.

Guerreros Tuareg (2007–2011) In 2007, most members of Pandilla Guerrera broke away from Los Guerreros del Infierno, wanting to break out of their shadow and move up the rankings themselves. Doctor X, Arkangel de la Muerte, Nitro, Skándalo, Hooligan and Loco Max formed a group originally known as Rebeldes del Desierto ("Rebels of the Desert") and later called Los Guerreros Tuareg ("The Tuareg Warriors"). Despite objections from Los Guerreros del Infierno that the name was too close to theirs, it stuck with the group. Doctor X became the interim co-leader of Guerreros Tuareg, along with Arkangel, when Nitro suffered a serious injury in early 2009. However, Doctor X did not work regularly in Arena México, CMLL's main arena, something which he expressed his unhappiness with, stating that he felt passed over for wrestlers with "1/10" his talent.

In April 2010, Doctor X began a feud with Fabián el Gitano, which saw both wrestlers intentionally get disqualified several times as they tore each other's masks off. During the twelve-man Lucha de Apuestas steel cage match in the main event of Infierno en el Ring ("Inferno in the Ring") on July 19, Doctor X primarily targeted Fabián el Gitano, but in the end, decided to leave the cage instead of trying to unmask Fabián. In the end, Ángel de Oro defeated Fabián, who was unmasked in the process. Doctor X took part in another twelve-man steel cage match on Christmas day in Arena Neza, including both CMLL and independent luchadores, winning the mask of Hermano Muerte III. On 4 August 2011, it was reported that Doctor X had quit CMLL.

Perros del Mal Producciones (2011) On 5 August 2011, Doctor X announced that he would join independent promotion Perros del Mal Producciones under the new ring name Doctor X-Treme. He wrestled his first match for the promotion later that same day.

Death On October 11, 2011, Valencia was shot in the head and killed when he tried to break up a fight while attending a religious party in Santa María Aztahuacán, Iztapalapa, Mexico City. He was survived by a wife and two children under the age of ten.
