Terrible is a uppercard rudo. Depending on who and when you ask, he's either a member of Perros del Mal or just an associate of the group who likes wearing their shirts. Terrible's probably below average as a worker, but has the size and a look that'll get him many opportunities, in case one clicks.
Terrible came to the CMLL Mexico City as part of the first Guapos U class. He was pushed strong in the group from the beginning, being part of the first match, and separated from the other new faces by being a bit of a rudo. Terrible was the ultimate winner of the first Guapos U, and became part of the Guapos trios with Shocker and Mascara Magica. With their help, he beat Bestia Salvaje for hair, and teamed with Perro Aguayo Jr. to take Mascara Ano 2000 and Cien Caras's hair.
Soon after, with the Guapos running a second Guapos U, Terrible gave into his rudo side and turned on Shocker and Mascara Magica. Terrible beat Magica for his hair, and they teased a ultimate match with Shocker. It was a match neither man could afford to lose, so the promotion never got around to it.
Terrible floating around on the rudo side after the Guapos feud. He filled in as an associate partner for Familia de Tijuana on occasion, but didn't really find a home till he teamed up with Perros del Mal.
With Magica mostly out of action and a rudo and Shocker in AAA, Terrible doesn't really have any feuds of his own. Terrible will help out with the Perros, he's still around the semimain level, but doesn't have any personal momentum.
Stuck with CMLL after most of the other Perros jumped ship, along with Texano Jr.. They started teaming regularly, and took on Rey Bucanero to form La Fuerza TRT. When Texano jumped to AAA Tiger became the second T in that group. During this time, Terrible became the CMLL World Heavyweight Champion and a sort-of Bullet Club member.
