Juventud Guerrera had an ill-fated run in WWE in 2005 as part of the Mexicools, a trio with Super Crazy and the original Psicosis. When he was turfed from WWE, he eventually got back in to AAA and formed the Mexican Powers. The initial team was Juvi, AAA's Psicosis II, and Crazy Boy, acting as his cousin's replacement. Joe Lider, long time indy associate of Crazy Boy, was later brought in to round out the team.

Crazy Boy and Joe Lider's background in hardcore wrestling became the theme for the group, with a lot of 'extreme' style spots (with a mixed success rate.) When Psicosis turned on the group to cost them Mexican National Atomicos Titles in April 2007, fellow hardcore wrestler Extreme Tiger was brought into replace him.

When Crazy Boy injured himself on his DTU show, Último Gladiador was brought in as a replacement for trios matches, and stuck with the group after Crazy's return.

Joe Lider turned on the group in the spring of 2008. Lider blamed Juventued Guerrera for the group's lack of big wins, saying Juvi didn't have the same dedication to the group as Crazy Boy did when he was healthy. Meanwhile, Juvi was angry with Lider for being out for himself in the Rey de Reyes ladder match, including turning on Juvi to better his own shot at winning. Things came to a head in a tag team title defenses versus Familia de Tijuana, where Lider cost his own team the championship and revealed he'd been paid off by Extreme Tiger to do so. Lider's since formed his own extreme faction, La Hermandad along with Juventud's former partner in the Mexicools, Nicho El Millionario.
