Kaizoku Gattai GokaiOh

Kaizoku Gattai GokaiOh (海賊合体ゴーカイオー, Kaizoku Gattai Gōkaiō, Pirate Combination Heroic King) is a giant robot formed from the Gokai Galleon and the Gokai Machines. An agile machine, it is armed with the twin Gokai Ken (ゴーカイケン, Gōkai Ken) swords and the built-in Gokai Hō (ゴーカイホー, Gōkai Hō) chest cannon. It also has the one-off Gokai Bat weapon, a gigantic baseball bat with the Gokaiger name on it, used against the Sneak Brothers; more specifically, the Elder Brother. 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 GokaiOh'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.

As part of GokaiOh, the Gokai Galleon forms the robot's head and torso.

Magi GokaiOh
When the Gokaigers use the Greater Power of the Magiranger Keys, GokaiOh becomes Magi GokaiOh (マジゴーカイオー, Magi Gōkaiō) with parts of the Magi Dragon emerging from the limb hatches and Gokai Hō. In this state, Magi GokaiOh can fly and even have Magi Dragon separate from it to attack independently. Its finishing attack is the Gokai Magi Bind (ゴーカイマジバインド, Gōkai Maji Baindo) during which MagiDragon is launched from GokaiOh, then circles the target three times, each pass making a Magiranger seal that then constricts the target. Once done three times, a beam of multi-colored magic rains down on the target.

Deka GokaiOh
When the Gokaigers use the Greater Power of the Dekaranger Keys, GokaiOh becomes Deka GokaiOh (デカゴーカイオー, Deka Gōkaiō) with parts of the Patrol Striker emerging from its limb hatches and Gokai Hō. In this state, Deka GokaiOh can use the parts of the Patrol Striker in its arms as firearms in its attacks and even have the Patrol Striker separate from it to attack independently.

Gao GokaiOh's finishing attack is the Gokai Animal Heart (ゴーカイアニマルハート, Gōkai Animaru Hāto), where GaoLion releases a powerful energy beam from it's mouth to hold the target in place, long enough for GokaiOh to deliver two powerful slashes from the Gokai Ken.

Shinken GokaiOh
When the Gokaigers use the Greater Power of the Shinkenger Keys, they summon GaoLion who undergoes the Gao GokaiOh transformation before combining with GokaiOh to become Shinken GokaiOh (シンケンゴーカイオー, Shinken Gōkaiō), a formation similar to Samurai Gattai ShinkenOh, as well as Hyakujuu Gattai GaoKing. Armed with the Gokai Naginata, Shinken GokaiOh has access to the Fire, Water, Earth, Wood, and Heaven Mojikara, enabling it to control the elements. Shinken GokaiOh's finishing attack is the Gokai Samurai Slash (ゴーカイ侍斬り, Gōkai Samurai Giri), summoning a mecha-scale Rekka Daizantou engulfed in flames as hot as 1,000°C (1,830°F) which then cleaves through the target.

When the Gokaigers use the Greater Power of the Gorenger Keys, they summon Variblune which combines with GokaiOh to become Goren GokaiOh (ゴレンゴーカイオー, Goren Gōkaiō). In this state, Goren GokaiOh can fly/hover by using the propellers on the Variblune as a helicopter pack. Goren GokaiOh's finishing attack is the Gokai Hurricane: Cassiopeia (ゴーカイハリケーン・カシオペア, Gōkai Harikēn: Kashiopea), where the Gokai Ken are combined into one sword then enlarged to an incredible size, possibly to double the length of Shinken GokaiOh's Rekka Daizantou, then executes a chopping slash, all while the five colored stars of the Gorengers appear in a "W" formation on the blade.

Goren GokaiOh first appears in Gokaiger Goseiger Super Sentai 199 Hero Great Battle.

Hurricane GokaiOh
When the Gokaigers use the Greater Power of the Hurricaneger Keys, they summon Fuuraimaru, which Gokaioh combines with in order to become Hurricane GokaiOh (ハリケンカイオー, Hariken Gōkaiō). In this state, Hurricane GokaiOh resembles Tenrai Senpuujin. It is covered with shuriken which can become a flail-like weapon called the Shushutto Shuriken Chain (シュシュッと手裏剣チェーン, Shushutto Shuriken Chēn). One of this form's two finishing attacks is called the Gokai Infinite Shuriken (ゴーカイ無限手裏剣, Gōkai Mugen Shuriken) during which Hurricane Gokaioh sends off a flurry of shuriken from the arms and legs, similar to Deka GokaiOh's Gokai Full Burst finisher, that strikes the target. The other, more used finishing attack is called the Gokai Wind-Thunder Attack (ゴーカイ風雷アタック, Gōkai Fūrai Atakku), which has Fuuraimaru separate from Hurricane GokaiOh before he uses the Secret Finisher: Turbulence Cherry Blossoms (必殺奥義・乱れ桜, Hissatsu Ōgi: Midare Zakura) to clone himself, then the clones and the original attack the target with their shurikens.

Go-On GokaiOh
When the Gokaigers use the Greater Power of the Go-Onger Keys, they summon Engine Machalon which combines with GokaiOh to become Go-On GokaiOh (ゴーオンゴーカイオー, Gōon Gōkaiō).

Go-On GokaiOh's finishing attack is the Gokai Go-On Grand Prix (ゴーカイゴーオングランプリ, Gōkai Gōon Guran Puri), where after ascending into the air through Hover Mode, Go-On GokaiOh drops down in a descending overhead slash with a Gokai Ken.

The Day of Battle
In The Day of Battle, Goren GokaiOh was shot out of the sky by the large fleet of Zangyack ships, along with GoZyuJin, GaoLion, Furaimaru, the Pat Striker, and MagiDragon. But, MagiDragon, Furaimaru, and Pat Striker were defeated, GaoLion was wounded, and Machalcon is forced back to the Machine World. GokaiOh was then destroyed by the Gigant Horse, with the GokaiGalleon suffering heavy damage. After the defeat of the Emperor and several months of repair work, the GokaiGalleon was restored to its former glory.
