González kept working as Black Tiger even when NJPW introduced Rocky Romero as the latest Black Tiger (Black Tiger IV) but due to their working relationship with NJPW, CMLL decided that when González worked for them he needed a different "persona". He was repackaged as "El Bronco" complete with a new mask and promoted as someone new to CMLL. González made his debut as "El Bronco" teaming up with Elektro (who had just jumped from AAA to CMLL) and L.A. Park against the original members of Los Guerreros del Infierno (Último Guerrero, Rey Bucanero, and Tarzan Boy). The match was seen as a letdown as the crowd did not appreciate Elektro and did not buy into the "El Bronco" gimmick and the scheduled rematch was rebooked with Hijo de Lizmark and Místico taking over their roles in the match and González as El Bronco replacing Lizmark Jr. in the 2005 Gran Alternativa tournament where his team lost in the first round. After the Gran Alternativa González only made sporadic CMLL appearances as González. González continued wrestling as Black Tiger in IWRG and in other independent Mexican wrestling promotions. On 4 February 2006, González finally gave up the Black Tiger name as he lost a "Lucha de Apuestas" to L.A. Park and was unmasked. After losing his mask González went back to working as Silver King.
