Power Rangers Dino Thunder is an American children's television series, the twelfth season of the Power Rangers franchise. As with all Power Rangers series, it was adapted from a series from the long running Japanese Super Sentai franchise, in this case the 27th entry, Bakury? Sentai Abaranger. Dino Thunder was also the subtitle of the Korean dub of Abaranger in South Korea and had a similar/identical logo to the American version as well. Currently, 23 of the 38 episodes are available in various volumes on DVD in Region 1, whereas a complete box set was released in Region 2 in July 2008. The series is notable as it features the return of Jason David Frank to a starring role.
