Mighty Morphin Power Rangers (MMPR) is an American superhero television series that premiered on August 28, 1993, on the Fox Kids programming block. It is the first entry of the Power Rangers franchise, and became a 1990s pop culture phenomenon along with a large line of toys, action figures, and other merchandise. The show adapted stock footage from the Japanese TV series Kyōryū Sentai Zyuranger (1992–1993), which was the 16th installment of Toei's Super Sentai franchise. The second and third seasons of the show drew elements and stock footage from Gosei Sentai Dairanger and Ninja Sentai Kakuranger, respectively, though the Zyuranger costumes were still used for the lead cast in these two seasons. Only the mecha and the Kiba Ranger costume from Dairanger were featured in the second season while only the Kakuranger mecha was featured in the third season, though the Kakuranger costumes were later used for the mini-series Mighty Morphin Alien Rangers. The series was produced by MMPR Productions and distributed by Saban Entertainment, while the show's merchandise was produced and distributed by Bandai Entertainment.

Kyōryū Sentai Zyuranger is a Japanese tokusatsu television series and the sixteenth installment in the long-running Super Sentai metaseries of superhero programs. Produced by Toei and Bandai, it aired on TV Asahi from February 21, 1992 to February 12, 1993, with a total of 50 episodes replacing Chōjin Sentai Jetman and was replaced by Gosei Sentai Dairanger. It was the first Sentai series to have a regular Sixth Ranger, and the first to introduce the concept of sentient, living mecha, a theme that has been used frequently in the franchise ever since. It was also the first Sentai series to be adapted into an installment of the American Power Rangers series. Footage from all 50 episodes was extensively used for the first season of Mighty Morphin Power Rangers. The core Zyuranger costumes were used in all three seasons of Mighty Morphin Power Rangers and were used as the original Power Rangers costumes while the Dragon Ranger costume was adapted into the Green Ranger's costume and was used throughout Season 1 and in early Season 2. The title Toei gives this series for international distribution is Galaxy Rangers.
