From Disney's Hollywood Studios Wiki
The Power Rangers are characters from a popular TV series, originally The Mighty Morphing Power Ranger, but has since gone by Power Rangers and a sub-name, such as Power Rangers: RPM. The show is adapted from the Japanese tokusatsu Super Sentai Series, though it is not simply an English dub of the original. Rather, it is a "new" production with English-speaking actors spliced in with the original Japanese footage in varying ratios. The Power Rangers series was distributed by Saban Entertainment from 1993 until the end of 2001 and was broadcast on Fox until the fall of 2002. The franchise was purchased by the Walt Disney Company as a part of the buyout of Fox Family that took place between 2001 and 2002, but, in 2010, Disney sold the franchise back to it's original owners, SABAN, and the Power Ranger will be leaving the park on August 7th, 2010.
 Studios Reference
The Power Rangers joined the Disney's Stars and Motor Cars Parade in 2005, with the latest ranger in the "Morphin' Transport" and the other four walking in front of the car.
