The Assault Grip (アサルトグリップ Asaruto Gurippu) is an attachment used with the Assault Wolf Progrisekey to transform into Kamen Rider Vulcan Assault Wolf or with the Shining Hopper Progrisekey to transform into Kamen Rider Zero-One Shining Assault Hopper. It was manufactured by the Ark along with the Assault Wolf Progrisekey. Originally, Zero-One had to share it with Vulcan, but Izu was able to produce a second copy for Aruto using the Hiden Intelligence Three Dimensional Printing System.
The Assault Grip is composed of the following parts:
- Assault Charger (アサルトチャージャー Asaruto Chājā): The operation button on the top of the Assault Grip. Pressing it activates the attached Progrisekey. After transformation, pressing it initiates the Assault Charge for finishing attacks. This overboosts the Rider Model to draw out overwhelming destructive power by putting it into an overloaded state.
- EMG Dister (EMGディスター EMG Disutā): A circuit breaker located on the Assault Grip's side. Pushing it in an emergency shuts down the system and prevents malfunctions from spreading to the attached Progrisekey. In addition, the Assault Grip and Progrisekey can be separated by using a physical shut-off mechanism on the back.
- The Assault Grip was originally called the "Assault Trigger" in early toy catalogs.
- Its ability to enhance a transformation trinket parallels the Gaia Memory Enhancing Adapter.
