He is also able to use his center chest piece named the **Hypnovision** (ヒュプノビジョン, *Hyupunobijon*) to control the Riders, by having it forcefully replace the Riders' Crest Mets and latch onto their heads.

Kamen Rider Onnen consists of the following parts:

* **Onnen Mask** (オンネンマスク, *On'nen Masuku*): The helmet.

	+ **Onnen Crusher** (オンネンクラッシュ, *On'nen Kurasshā*): The mouth guard.
* **Reflective Suit** (リフレクトスーツ, *Rifurekuto Sūtsu*): The suit. By supplying energy from the Shadowside Riser, it has the ability to dramatically improve the physical abilities of the user. It boasts impregnable defensive power by deploying the electromagnetic deflection shield **Electric Deflector** (電気デフレクター, *Denki Defurekutā*) from the shell-like **Deflect Pits** (デフレクトピット, *Defurekuto Pitto*) arranged throughout the body.
* **Diffusion Armor** (拡散アーマー, *Kakusan Āmā*): The armor. Comprised of an unknown material called **Starry Material** (スタリーマテリアル, *Sutarī Materiaru*), it provides a high level of hardness that exceeds that of diamonds while also possessing outstanding toughness, repelling all kinds of impacts.
* **Hypnovision** (ヒュプノビジョン, *Hyupunobijon*): The suit's control device. The Hypnovision can separate from the Diffusion Armor and forcibly attached themselves onto the heads of Kamen Riders to bring them under Onnen's control. Five are present in total, forming Onnen's chestplate, shoulder pads and knee guards when not in use.
* **Electronic Control** (電子コントロール, *Denshi Kontorōru*): The arrow shaped circuit board underneath the chest part of the Diffusion Armor.
