The Suigetsu (Japanese for "Water Moon") is a knightmare frame utilized by the Order of the Black Knights in Code Geass Megiddo as their primary amphibious unit.


Pretty much a standard Gekka, but reoriented for its chosen environment. It is equipped with hydrojet thruster pods mounted over the cockpit pod, as well as unique torpedo launchers, which are based on the Dorado L's missile pods from Mobile Suit Gundam AGE.


The Suigetsu's basic body and form was based on a standard Gekka, except that its armor had been modified with waterproof seals (especially around the cockpit), and miniature hydro jet thrusters like those of Britannia's Bristol. For its intended purpose, the Suigetsu carries weapons designed for usage underwater as well as dry land, such as wrist mounted torpedo launchers, arm held tanto (knives), and the standard slash harken. Despite these specialized weapons however, the Suigetsu is capable of mounting more land-based weaponry should the need arise.


In her pursuit of variants of the versatile Gekka line to fill specific mission rolls, as well as develop an effective defense for the Ryukyu Islands, Order of the Black Knights engineer Rakshata Chawla took the original design and modified it substantially for underwater and amphibious warfare, thus developing the Suigetsu. As its name would suggest, the Suigetsu was meant to provide coastal defense for the Ryukyu Islands and keep any Britannian patrols from coming too close to them, though it was more than capable of fighting against Britannian amphibious units. As such, when the Black Knights renew their war against Britannia, the Suigetsus remain behind to continue their "coast guard" duties, usually deployed from Ryujin-class carrier submarines to ward off any potential invaders.

Every so often, however, the Suigetsu would see frontline action. One such event was during the Black Knights' siege of the Britannian naval basin of Pearl Harbor in Area 7, the Sandwich Islands. During the operation, a taskforce composing of the submarines Ryujin and Isonade as well as the Mikasa-class mobile cruisers Mikasa and Hiei would be used to divert the bulk of the Britannian Pacific Fleet away from Pearl. While this was accomplished, the flagship Izumo would take the opportunity to slip past the other coastal defenses and attack the island basin in a surgical strike. When the time came, the Black Knight taskforce then shed its cover and attacked the Pacific Fleet directly, during which Suigetsus were employed to combat the Britannian Bristols in underwater combat.
