Chamaco Ortiz, Rey Pirata, Hombre Bala, Cromagnon, Cavernícola II, Pirata Negro, Fantasma De La Opera (AAA, 2/6/01), the Monsther (2001-2010) (pronounced as "Monster")
A man of many names. Hombre Bala might have been the most famous, but his current character of Monsther is either close or better. That gimmick was a creation of AAA, where he worked as a midcard comedy rudo (teaming with Chucky, feuding with Alebrije and Cuije) for many years. Left AAA in 2008 and works as independent.
As he's a wrestler putting a mask back on after losing it (repeatedly), it's rarely publicly acknowledged that Monsther is the same man as Hombre Bala or Rey Pirata. His children are mentioned as sons and daugther of Hombre Bala (and he made a television appearance with them as Hombre Bala), but there's no connection made to Monsther.
When the CMLL vs Invasors story started in CMLL, Monsther appeared along side other ex-AAA and independent wrestlers. Monsther (and Chucky) were only rarely seen, but it eventually became clear this was a different Monsther than previously seen. Hombre Bala also again appeared on CMLL TV features around this time, wearing his Hombre Bala match.
A Hombre Bala benefit show was held on September 16, 2010. Hombre Bala had been injured training young luchadores, and needed money for surgery. Even after the surgery, he will not be able to return to the ring. During the show, it was confirmed that both the new Monsther and Hombre Bala Jr. are his sons.
