Kid Kaos dropped the "Kid' and just went as "Kaos" after that. I think I'm talking about the right guy.
He did do some CZW shows and I understand he didn't impress anyone. I in particular kind of liked his look and style, even if he wasn't the best wrestler. He trained a little at the New Japan Dojo and worked some shows as "Joey Kaos", and if he would have stuck it out there, probably could have amounted to something really good, at least got some Japan shots. His "Rock Superstar" gimmick was pretty damn entertaining I thought.
I think he still wrestles at FCW, and some other XPW knock-off feds around SoCal. He tags with a guy named El Mongol as the "Fighting Santino Brothers"
