The Spider-Type Roidmudes (スパイダー型ロイミュード Supaidā-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 spider motif, called a Spider-Type Giant Roidmude (スパイダー型巨大ロイミュード Supaidā-gata Kyodai Roimyūdo), via the absorption of three Viral Cores or two if they have already evolved into their Advanced Roidmude form.
