#6 The Monster Matanza
Well, anyone who watched Lucha Underground would have undoubtedly have been left speechless when Matanza Cueto finally debuted and ran roughshod through the entire roster in one night.
While his identity wasn't kept secret for long, the identity of Matanza was definitely much sought after when he first appeared.
A top AEW star just called one of his colleagues 'spoiled' and 'narcissistic' HERE.
Jeff Cobb, the man behind the mask, has represented Guam at the Olympics for amateur wrestling, is a huge name on the indies and has wrestled for NJPW. He's a star in his own right, but has undoubtedly never made quite the impact he did as Matanza Cueto in Lucha Underground.
