When does Power Rangers return?

Power Rangers is an entertainment and merchandising franchise built around a live-action superhero television series, based on the Japanese tokusatsu franchise Super Sentai. The first Power Rangers entry, Mighty Morphin Power Rangers, debuted on August 28, 1993, and helped launch the Fox Kids programming block of the 1990s. By 2001, the media franchise had generated over $6 billion in toy sales. In 2010, Haim Saban, creator of the series, regained ownership of the franchise, which was previously owned by Disney.
Power Rangers derives most of its footage from the Super Sentai series. Each series revolves around a team of youths recruited and trained by a mentor to morph into the eponymous Power Rangers. When "morphed," the rangers become powerful superheroes wearing color-coded spandex suits and helmets with opaque visors.
