The son of Mexican star, Fuerza Guerrera, Juventud Guerrera arguably had a better career then his father, or at least one that is more celebrated.

Rey Mysterio Jr. was the premier high flyer of Lucha Lubre in the 90s, but he needed dance partners, and for a time, there was nobody better than Guerrera.  Juvi and Rey tore it down in AAA, ECW, and then WCW, where they both held the Cruiserweight Title multiple times.  Guerrera rarely competed outside of the lighter weight class in WCW, but he didn’t need to, and opened many cards with a bang.

In 2005, Guerrera made it to the WWE, as the leader of the Mexicools faction with Super Crazy and Psicosis, and though his run was brief, he was a two-time WWE Cruiserweight Champion

Attitude problems were Guerrera’s downfall, and if he never sniffs the WWE Hall of Fame, that would likely be why.  He notably was released from WCW when on an Australian tour he was drugged out of his mind and was found outside, completely naked and violently fighting with police officers.  Guerrera

Also was relieved of his job in the WWE, when he performed the then-banned shooting star press.
