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 Plain Roidmudes. They can also forsake their humanoid forms and transform into a larger shape more befitting their spider motif, called a Spider Type Roidmude Berserk Body (スパイダー型ロイミュード暴走体 Supaidā-gata Roimyūdo Bōsō-tai), via the absorption of three Viral Cores or two if they have already evolved into their Evolution State (進化態 Shinka-tai) form.

Through data stolen from the Roidmudes through a currently unknown source, Megahex created a force of Plain Roidmudes (Lost Number) (プレーンロイミュード(ロストナンバー) Purēn Roimyūdo Rosuto Nanbā), mechanical and numberless recreations of the Plain Roidmudes, to combat the Kamen Riders that stood in his way of assimilating Earth and its inhabitants. What surviving members of these Plain Roidmude (Lost Number) in the final battle between ZZZ Megahex's army and the Kamen Riders and Roidmude generals were deactivated upon ZZZ Megahex's permanent death.
