A Giant Roidmude (巨大ロイミュード Kyodai Roimyūdo) is a form which can be accessed when a Roidmude uses more than one Viral Core at one time (three for Low-Class, and two for Advanced), causing them to change into a bigger and more powerful form based on their animal motifs as well as greatly resembling their respective Viral Cores, but at the cost of their intelligence.
