This wrestler, that gained some fame as Mascara Sagrada Jr., quit AAA and started wrestling in the independent circuit with the identity of Muerte Roja, a gimmick that was already used by Venum Black a few years ago. He appears to have gone back to AAA to become the new Alebrije, which has not yet made it on TV.
Please note AAA disputes the contents of this entry (though their specific complaint remain unclear, it may be confusion over who was Muerte Roja and Super AAA when/at all.)
