Kaizoku Gattai GokaiOh

Kaizoku Gattai Gokai Oh (海賊合体ゴーカイオー) is a giant robot formed from the Gokai Galleon and the Gokai Machines. An agile machine, it is armed with the blaster cannons of Gokai Jet and Racer in its forearms, the twin Gokai Ken (ゴーカイケン) swords, and the built-in Gokai Hō (ゴーカイホー) chest cannon. (According to the series' website, it also has a row of beam canons in each shoulder and Vulcans in its hat.) It also has the one-off Gokai Bat (ゴーカイバット) weapon, a gigantic baseball bat with the Gokaiger name on it, used against the Sneak Brothers; more specifically, the Elder Brother. Its default finisher is the Gokai Star Burst (ゴーカイスターバースト), where the wheel on Gokai Oh's back spins and the hatches on each limb opens up, revealing a unlimited line of cannon balls in each limb which are then fired out of the Gokai Hō in rapid succession. Gokai Oh can also perform a double cross cut with the Gokai Ken called the Gokai Crash (ゴーカイクラッシュ).

The Gokai Galleon (ゴーカイガレオン) is a three-masted galleon-like spacecraft, originally possessed by AkaRed with his Red Pirate shipmates, Marvelous and Basco ta Jolokia. After Basco betrayed them, AkaRed saved Marvelous and left him the first of the Mobilates before perishing in battle with the Zangyack. Marvelous and the other Gokaigers use the ship as their transportation and base of operations as they search for the Greatest Treasure in the Universe.

It is equipped with the Galleon Cannons (ガレオンキャノン), along its sides, beam cannons on its wings and lower bow, and a bladed bowsprit that is able to ram through enemy ships. When not forming Gokai Oh, Gokai Galleon holds the other Gokai Machines within it similar to a Matryoshka doll, with Gokai Trailer as the second largest mecha followed by Gokai Marine, Gokai Racer, and finally Gokai Jet. As part of GokaiOh, the Gokai Galleon forms the robot's head and torso while the bowsprit forms the Gokai Ken.

It was heavily damaged as a result of facing the Zangyack invasion fleet in The Day of Battle, but was fully repaired in the finale, several months after the death of Ackdos Gill and the Zangyack as a true empire.

Hurricane GokaiOh has two finishing attacks:


 * 1) the Gokai Infinite Shuriken (ゴーカイ無限手裏剣), which Hurricane Gokai Oh sends off a flurry of shuriken from its arms and legs, similar to Deka Gokai Oh's Gokai Full Burst finisher, and
