El Jefe is none other than Dario Cueto.
The man who ruled Lucha Underground with an iron fist, Cueto’s presence in MLW has been teased for quite a while. MLW has been incorporating the Lucha Underground mythos into its own world in recent months, as former champion Mil Muertes now competes on MLW Fusion. In fact, MLW has been building a new version of the popular promotion in Azteca Underground.
