Mighty Morphin Power Rangers

Mighty Morphin Power Rangers (abbreviated as MMPR) is an American live-action television series, created for the American market, based on the 16th installment of the Japanese Super Sentai franchise, Kyōryū Sentai Zyuranger. This is the first in the USA series of Power Rangers. Both the show and its related merchandise saw unbridled overnight success, catapulting into pop culture in mere months. Under the original name Mighty Morphin Power Rangers, the series ran from 1993 to 1996 and spawned a feature film, Mighty Morphin Power Rangers: The Movie.

The second and third seasons drew on footage and elements from the Super Sentai series Gosei Sentai Dairanger and Ninja Sentai Kakuranger respectively, though the Zyuranger costumes were still used for the main five Rangers and several regular villains. Only the Zords and the Kiba Ranger suit (worn by the White Ranger) were retained from Dairanger for the second season, while the five Kakuranger suits were used in the mini series, Mighty Morphin Alien Rangers; however, the Kakuranger Zords were featured extensively in season 3 of the show, and served as the basis for the Zords seen in the movie produced between seasons 2 and 3 (although they appeared in American-produced CGI in that film). The series was produced by MMPR Productions, distributed by Saban Entertainment, and aired on Fox Kids.

In 1996, the Mighty Morphin label was retired as the series would follow in the footsteps of Super Sentai, changing its name, cast and plot every year; thus the Power Rangers franchise was born. Power Rangers still runs in this format to this day, though currently the majority of post-MMPR series are not spin-offs in the traditional sense.
