The CFK-029 Demon Judge is a new MS developed by Grassley Defense Agency, which is the successor to the CEK-040 Heretic Judge and also equipped with a formatting system interference device - "anti voodoo". The aircraft was secretly developed by the Grassley Defense Agency after the Vannados Incident, and one of the upgrade plans was to add attack capabilities to the "anti voodoo" armed forces. The most unique feature of the body is that the traditional robotic arm on the right arm has been replaced with a composite suit, which can not only release the "anti voodoo" system and interfere with the links of the GUND framework, but also transform into various modes such as beam swords, beam cannons, and beam machine guns.
