As we all know, GokaiOh made its debut on the show's first episode, but we never had a chance to see how they formed it. On the show's second episode, finally, they finally showed how the Gokai Galleon and its four other individual mecha turn into their giant robo, Pirate Combination GokaiOh!
All four Gokai Machines namely, Gokai Jet, Gokai Trailer, Gokai Racer and Gokai Machine come outside the Gokai Galleon and go to outer space and land into the moon to form the GokaiOh! This formation sequence is similar to Megaranger's Galaxy Mega formation, except that they never landed on the moon.
Its finishing attack is the Gokai Star Burst (ゴーカイスターバースト, Gōkai Sutā Bāsuto?), where the wheel on Gokaio's back spins and the hatches on each arm and leg opens up, revealing several cannon balls which are then fired out of the Gokai Hō in rapid succession at the target.
