Sclash Driver

The Transformation Belt Sclash Driver (変身ベルト スクラッシュドライバー) is the transformation belt used by Kamen Rider Cross-Z Charge, Kamen Rider Grease and Kamen Rider Rogue. Conceptualized by Takumi Katsuragi as the evolution of Project Build, its schematics were completed by Sento Kiryu and copied by Soichi Isurugi. It was later revealed that, similar to the requirement for the Build Driver, using the Driver requires a minimum Hazard Level of 4.0 (as opposed to the former's requirement of 3.0), otherwise it will inflict a painful surge of energy upon the attempting user..

Functionality
To transform with the Sclash Driver, Sclashjellies are inserted into the Power Press Slot of the belt, and the Activate Wrench is pumped to crush the Sclashjelly. In the show and toyline, Fullbottles are also fully compatible with the Sclash Driver.

Constant usage of the Sclash Driver exposes the user to the unshielded effects of the Nebula Gas, similar to the exposure to the light of Pandora Box: every transformation makes the user grow increasingly aggressive and become obsessed with fighting, such as in the case of Kazumi Sawatari (Kamen Rider Grease).

Anyone with a Hazard Level of below the minimum requirement of 4.0 attempting to transform will be painfully shocked and forced to eject the Driver and Sclashjelly off of their waist. Even for those who have met the prerequisite, those going through their first transformations will experience the electrical shocks, but once they have mastered it they no longer have this concern, overcoming the side effects as in the case of Ryuga Banjou and Kazumi Sawatari.

Design
The Sclash Driver is composed of the following parts:
 * Activate Wrench (アクティベイトレンチ): The like lever on the right hand side of the Driver. Used for transformation and to execute finishing attacks. When the wrench is pushed, the press mechanism of the Power Press Slot operates, squeezing the components of the Sclashjelly into the Driver.
 * Power Press Slot (パワープレスロット): The slot the Sclashjelly is inserted into. A pressing mechanism is used to take the components of the Sclashjelly into the driver.
 * Jelly Tank (ゼリータンク): The cylindrical section located on the left hand side of the Driver. It takes in the Sclashjelly's components via a tube and converts it into a substance called Variable Jelly (ヴァリアブルゼリー) that responds to special pulses emitted by the driver and has characteristics that allows it to change into suit components or armed weaponry.
 * Jelly Tank Cap (ゼリータンクキャップ): The red section on top of the Jelly Tank. its function is to emit a pulse that allows the Variable Jelly to change into armor or weapons.
 * React Dynamo (リアクトダイナモ): The energy source of the Sclash Driver. It is located at the bottom of the Driver. It operates at high speed and generates the necessary energy to activate transformation and deliver finishing attacks.

Finishers
While transformed, Cross-Z Charge/Grease/Rogue initiates a finishing move by pumping the Activate Wrench.

Cross-Z Charge uses the Scrap Break (スクラップブレイク) with the Dragon Sclashjelly. Grease uses the Scrap Finish (スクラップフィニッシュ) with the Robot Sclashjelly. Rogue uses the Crack Up Finish (クラックアップフィニッシュ) with the Crocodile Crack Fullbottle.

A finisher with an Organic Fullbottle is called the Charge Crash (チャージクラッシュ) while a finisher with an Inorganic Fullbottle is called the Discharge Crash (ディスチャージクラッシュ).

Kamen Rider Grease
After pumping the Activate Wrench of his Sclash Driver after transforming, Grease can activate a finisher tied to either the Robot Sclashjelly or a Fullbottle. Robot Sclashjelly=
 * Rider Kick: Grease uses his Machine Pack Shoulder (マシンパックショルダー) to generate Variable Jelly (ヴァリアブルゼリー) in order to propel himself forward as he delivers a powerful Kick to the enemy, coated in gold energy.
 * Rider Punch: Using the Machine Splash Armory (マシンスプラッシュアーモリー) on either of his hands, Grease performs a powerful punch with a Variable Jelly projection of the Demolition One.
 * Rider Shooting: In Ganbarizing arcade game, Grease fires four Robot Fullbottle insignia from his Machine Pack Shoulders and Machine Splash Armory as they explode upon latching to his targets.

Kamen Rider Cross-Z Charge
After pumping the Activate Wrench of his Sclash Driver after transforming, Cross-Z Charge can activate a finisher tied to either the Dragon Sclashjelly or a Fullbottle. Dragon Sclashjelly=
 * Rider Kick: Cross-Z Charge does a flying sidekick, which a dragon's head forms around his right leg.
 * Rider Punch: Cross-Z Charge delivers a punch with his fist covered in cyan and orange energy.

Kamen Rider Rogue
After pumping the Activate Wrench of his Sclash Driver after transforming, Rogue can activate a finisher tied to any Fullbottle. Crocodile Crack=
 * Rider Kick: Using the Cruncher Edges (クランチャーエッジ) on his legs, Rogue generates an energy crocodile head Cruncher Fang (クランチャーファング) to crush his target with before launching them away. Alternatively, he can also perform a spinning kick attack by charging his leg with purple energy.
 * Rider Punch: By charging energies into the Death Roll Glove (デスロールグローブ), Rogue delivers a punch that is strong enough to kill a Hazard Smash.
 * Rider Shooting:

Combinations

 * Build (in his RabbitTank Sparkling Form) and Cross-Z Charge perform a combination of Build's Sparkling Finish and Cross-Z Charge's Scrap Break.
 * Cross-Z Charge and Grease perform a combination of their Single Finish.
