Technology & Combat Characteristics

An underwater combat form of the Core Gundam docked with the Mercury Armor. As the PLANETS System allows the Core Gundam to instantly change its specifications to suit different battle environment and battle stages, the Mercuone Gundam was intentionally built as a mobile suit limited to underwater battles. It is one of the few dedicated to underwater operations, with most mobile suits capable of operating underwater being amphibious units or also having ground combat capabilities.

The Mercuone Gundam has a silhouette with large fins across its entire body and was designed to have excellent mobility in the depths of the sea, and the armor sections with improved pressure resistance have also enhanced its defensive capabilities. It has a large backpack with large fins for attitude control and water jets for underwater propulsion. It is also equipped with active sonar for detecting enemies underwater and its armaments include the Water Needle Gun equipped with Underwater Bits and Fin Zambers.

History

The Mercuone Gundam played an active part during the underwater battle to reach the Silver Tower in the mission on Eldora.
