The GokaiGalleon Buster (ゴーカイガレオンバスター Gōkai Gareon Basutā) is a double-barreled bazooka-styled cannon in the shape of the GokaiGalleon. It is created by Don after tinkering with the Gokai Guns to use more than one Ranger Key per weapon. At first, he was only able to create the handle with two barrels and five Gokai Cylinders, but with Gai's suggestion and comparison with the Ohranger's Olé Bazooka, he uses the Greater Power of the Ohrangers and after turning all five keys, they transform it into the GokaiGalleon Buster.
