[4] Between 1999 and 2002 or 2003 the Kempo Kid would win several Lucha de Apuestas, or "bet matches" where he forced his opponents to unmask as a result.

In late 2002, or early 2003 Kempo Kid lost a Lucha de Apuestas match to Stuka Jr. and was forced to unmask.

As part of the tradition wrestlers are supposed to announce their real name, which means that Aguilar revealed that he was the son of El Texano.

[8] On April 29, 2007 the team lost the Mexican National Trios Title to the Los Perros del Mal ("The Bad Dogs") faction of Mr. Águila, Damián 666 and Halloween.

The title change came about as El Texano Jr. turned on his partners mid-match, giving Los Perros del Mal an easy victory.

[9] Not long after turning Rudo (the Lucha Libre term for heel, or villain) Texano Jr. joined Los Perros del Mal and began teaming with El Terrible on a regular basis.

The match involved Los Perros del Mal, represented by Texano Jr. Damián 666, Mr. Águila, El Terrible and Perro Aguayo Jr. while the tecnico (Face or good guys in wrestling) side was represented by Alex Koslov, Marco Corleone, Shocker, Negro Casas and Heavy Metal.

On March 8, 2009 Texano Jr. won his second big "Luchas de Apuestas" match, defeating former teammate Máximo, forcing him to have his head shaved.

[15] On July 24, 2009 El Texano Jr. made his first successful NWA World Light Heavyweight Title defense, defeating former champion Shocker.

[16] In the fall of 2009 Texano Jr. and El Terrible became involved in a long-running "Mexico vs. Japan" storyline that had been going on since the summer as they began working with the Japanese duo No Limit (Yujiro and Naito).

The second round was a rematch from the previous year's tournament, only this time La Sombra eliminated El Texano Jr. and not vice versa.

After victories over Takashi Iizuka and Toru Yano and No Limit, Texano Jr. and Terrible finished fifth in their block and didn't advance to the semifinals of the tournament.

[25] In April 2011, Texano Jr. and El Terrible left Los Hijos del Averno to form a new group with Rey Bucanero.

[30] Later that day at an International Wrestling Revolution Group (IWRG) event, both El Texano Jr. and Súper Nova joined the Perros del Mal stable.

On the March 25 episode Texano unsuccessfully challenged el Patrón for the AAA Mega Championship in a Bullrope match.

Texano made his Impact Wrestling debut, helping El Hijo del Fantasma and Pagano defeat Eddie Edwards and Ethan Carter III, after the match the three deliver a post match beat-down with Texano using a rope to whip before James Storm made the save.

[5] On February 13, 2019 it was reported that Aguilar had filed a lawsuit in California against the El Rey Network and the Baba-G production company behind Lucha Underground.
