Arcle (Prototype) (アークル(プロトタイプ), Ākuru (Purototaipu)) is the transformation belt of Kamen Rider Kuuga Prototype, it is a prototype version of Arcle. Like Kuuga's Arcle, it is a transformation belt created by embedding a spiritual stone Amadam, but this "Amadam" does not have a function to control "the darkness of the heart". It has the potential to transform the user into a "terrible warrior" (Ultimate Form) and run away.
