Xristo Diavlo is perhaps the most frightening and intimaditing man to ever step into a wrestling ring. This real life satanist and self proclaimed Metal Messiah was a terrifying person to work with in CHW and was one of the best and most unique stars.
Some wrestlers play a character of a monster but Xristo gave an aura that he would literally be able to committ murder on you.
I don't think we will see as frightening or terrifying figure in wrestling to come!
