Sixth Power Rangers

Sixth Rangers are Power Rangers that don't immediately join until 1/4 of the way through a Power Rangers season. Some that join were former villains (i.e. Tommy, Ryan, Merrick, Trent, etc.), some that were reluctant to join (i.e. Eric, Tyzonn, Sir Ivan of Zandar, etc.), and some that joined once they were discovered (i.e. Trey, Jason, Zhane, Mike, Cam, Sam, Daggeron, Antonio, Orion, Levi, etc.)
