Mighty Morphin Power Rangers is an American superhero children's 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 alongside a large line of 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. The shows path to US television was anything but smooth, however.
