Mighty Morphin Alien Rangers is a Power Rangers miniseries set at the end of the third season of Mighty Morphin Power Rangers. As with the rest of the third season of Mighty Morphin Power Rangers, this series adapted footage and costumes from the eighteenth Super Sentai series, Ninja Sentai Kakuranger. During fight scenes, an alternate version of the MMPR theme song was played, saying "Go Go Alien Rangers" instead of "Go Go Power Rangers".
