Gekka (Pre-Production Test Type)

After the success of the Guren, the Kyoto House commissions a mass production version, which would be known as the Gekka. Before the production model is created, genius engineer Rakshata Chawla constructs a prototype version in order to test the viability of the Gekka. The pre-production Gekka mounts an early version of the Guren's radiation wave arm; despite the less efficient energy use and output, it can still destroy any standard knightmare frame with a single burst. Aside from the radiation wave arm, the only real difference between the pre-production model and the finalized Gekka is its distinctive blue color scheme. The arm was later customized and used on the Guren Type-02 in 2018, after losing its original arm in the battle of Tokyo. This unit only appears in Code Geass: Lost Colors, piloted by the protagonist Rai if the player chooses the Order of the Black Knights route.
