Battalion Mars

The SS Adriatic was a German ship that ran joint operations with the Japanese Navy. An exercise was called at the last minute, causing Hyousuke Obra, who was supposed to lead the Akuareigers, to be deployed.

During the mission, it was destroyed by Vulcan Worm, which was a former monster of Black Manta, but Hyousuke survived and was corrupted into Shamu of the Abyss. He was working on restoring the Adriatic into a robo, initially tasked with defeating the Akureigers. However, he was freed from his bounds of evil and ended up going up against a clone of his creation, and defeating it successfully. He later created the War Machines to be able to combine with Battalion Mars.

SS Adriatic
After being restored, the Adriatic resembles a large battleship, but not the aircraft carrier it once was. It now has a crane attached to one side

Battalion Mars
The crane folds out to form the right arm, the back opens to revel the legs and head, the control tower comes off to become the left arm, which is a runway/saw blade hybrid. In the show, he uses the Adriatic's control tower for the cockpit as Battalion Mars.
