The Behemoth is a Eurasian Knight Giga Fortress in Code Geass Megiddo.


The Knight Giga Fortress version of the Xamel from Mobile Suit Gundam 0083: Stardust Memory. Colored in hellgrau like everything else Eurasian.


A product of the "Missing" Sixth Generation, the Behemoth was developed around much experimental technology for its time. One of its main features is a built-in float system, which is mounted in its main body. Much like the Britannian Vortigern, the float system grants it exceptional ground mobility for its size, as well as the ability to move across virtually any terrain, up to and including water. This makes the Behemoth ideal for its role as an artillery unit, but also belies its true intended function.

In truth, the Behemoth was designed as a compact, mobilized version of the Balmung ion cannon. For this purpose, it is equipped with a miniaturized version of the weapon, which is kept on its back and unfolds over when in use. Though much smaller than the edifice in Volgograd, the cannon's power and range are not diluted in the least, such that it can reach the high altitude reflector drones utilized by the original weapon to direct its fire. This alone makes the Behemoth a terrifying weapon, as its smaller size and ability to move make it much harder to pinpoint than the original Balmung. When necessary, the cannon's power can be reduced so that it can be used as a standard longer ranged blitz cannon for fire support. This in turn is supplemented by an eight tube box missile launcher and a turret mounted blitz vulcan for close quarters defense.


One of the myriad "phantom" weapons that may or may not actually exist, the Behemoth was possibly developed sometime after the original Balmung cannon (itself developed at an unknown time) as a mobilized option, possibly even as a prototype for further such KGFs. However, much like its "sibling", the amphibious Leviathan, it is unknown if the Behemoth was ever truly produced or actually conceptualized. On the other hand, as the Great World War continues on, both Eurasia and Britannia begin to roll out weapons and technology that they purportedly did not possess during the early stages, leading some within MI6 and other intelligence apparatuses to believe that the Behemoth and similar instruments not only exist, but that Eurasia indeed plans to utilize them during a pivotal stage of the war. For the time being however, there have been no known sightings of the Behemoth, or any indication of its actual development.
