The Bat-Type Roidmudes (バット型ロイミュード Batto-gata Roimyūdo) were one of the three basic combatmen types of Low-Class Roidmudes. They can also forsake their humanoid forms and transform into a larger shape more befitting their bat motif, called a Bat-Type Giant Roidmude (バット型巨大ロイミュード Batto-gata Kyodai Roimyūdo), via the absorption of three Viral Cores or two if they have already evolved into their Advanced Roidmude form. A total of 38 Bat-Type Roidmudes existed among the 108. They became extinct with the death of Roidmude 101. Why Must They Fight?
