Around the turn of the millennium, Crazy Boy worked extensively in Naucalpan, Mexico State, for the then recently created International Wrestling Revolution Group (IWRG).

He won the AAA promoted "Campeonato National de Atomico" (4 man tag team championship), along with Juventud Guerrera, Joe Líder and Psicosis II.

Along with Joe Líder and Juventud Guerrera, the group traveled to Japan to compete in Pro Wrestling Noah's TripleSEM, where they were victorious.

Joe Líder broke off his connection to Mexican Powers, losing his and Crazy Boy's AAA World Tag Team Championship to the Halloween and Extreme Tiger.

On November 16, 2007, Crazy Boy defeated Zema Ion and Extreme Tiger in a three-way Light Tube match.
