It has finally been confirmed via the Power Rangers panel at the San Diego Comic-Con that the footage for Kaizoku Sentai Gokaiger will be used on Megaforce's second season, tentatively known as Power Rangers Super Megaforce.
Power Rangers Megaforce will be using the footage of the 34th Super Sentai series, Tensou Sentai Goseiger. It features Gosei, a supernatural guardian, who protected the Earth for centuries along with his robotic aide, Tensou.
During the massive invasion of the evil Warstar aliens, Gosei calls upon five teenagers with attitude to form the ultimate team... the Power Rangers Megaforce. It premieres in early 2013 on Nickelodeon.
