El Jefe has arrived in MLW and it is indeed Dario Cueto.
MLW has teased Azteca Underground's El Jefe for weeks with the promotion being involved with Salina de la Renta and buying Promociones Dorado. Operating out of a temple in California, not much was known about the El Jefe of Azteca Underground, but on Wednesday's MLW Fusion, Dario Cueto revealed himself, saying he would be in Philadelphia for the new MLW season in July.
Cueto mentioned that he is continuing to build his temple and it required sacrifices. The implication was Salina de la Renta was sacrificed at the end of the show.
Cueto (played by Luis Fernandez-Gil) famously ran Lucha Underground and was universally praised for his work as the on-screen owner and promoter of the company. MLW has honored the lore of Lucha Underground throughout this season, including reviving former Lucha Underground Champion Mil Muertes.
