Power Rangers Operation Overdrive is the fifteenth season of the television franchise Power Rangers. The season uses footage and other material from the 30th Super Sentai series GoGo Sentai Boukenger, which celebrates the thirtieth anniversary of that franchise. In addition, this season's team-up episode, "Once a Ranger", commemorates the fifteenth anniversary of the Power Rangers franchise. The season premiered on February 26, 2007,[1] on Toon Disney's Jetix programming block. It was the first season to use high definition/widescreen footage from the Super Sentai franchise, although this footage was scaled down to 4:3 aspect ratio. Unique among Power Ranger series, Operation Overdrive has the Rangers exploring, operating and fighting in many different countries around the world, rather than focusing only on their home city of San Angeles.
