Titan'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 concealed from the wrestling fans.

Titán began his in-ring career in 2008, working primarily in CMLL's local Guadalajara arena under the ring name Palacio Negro.

[26] Titán and Bárbaro Cavernario were paired up for the 2015 Torneo Nacional de Parejas Increíbles ("Inicredible teams tournament) as part of an ongoing storyline rivalry between the two over the Mexican National Welterweight Championship.

[30] In 2018, Titán began to team with his old partner Tritón and Esfinge, forming a trio known as La Excelencia Tapatia ("Masked excellence") and later as "One Atos".

[32] For the 2019 Torneo Nacional de Parejas Increíbles, CMLL paired Titán with long time rival Bárbaro Cavernario as they had done for the 2015 and 2018 tournaments.

The duo defeated Blue Panther and Máscara Año 2000 in the first round, Soberano Jr. and Sansón in the quarter final, Carístico and Mephisto in the semi-finals,[34][35] and Volador Jr. and Último Guerrero to win the tournament.

[38][39] On December 3, 2019, Titán and Soberano Jr. outlasted Audaz, Negro Casas, Drone, Fuego, Fugaz, Dulce Gardenia, Rey Cometa, Star Jr., Stigma, and Templario to qualify for a match for the vacant CMLL World Welterweight Championship the following week.
