The Transformation Belt Sclash Driver (変身ベルト スクラッシュドライバー Henshin Beruto Sukurasshu Doraibā) is the transformation belt used by Kamen Rider Cross-Z Charge, Kamen Rider Grease and Kamen Rider Rogue.


The Sclash Driver was created to serve as the evolution of Project Build, using Sclashjellies as its collectible device.

A minimum Hazard Level of 4.0 is required to be able to transform using the Sclash Driver, otherwise it will inflict a painful surge of energy upon the attempting user.The Forbidden Item.


To transform with the Sclash Driver, Sclashjellies are inserted into the Power Press Slot of the belt, and the Activator 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). The Golden Soldier However, with enough experience, such effects become less noticeable over time.

Anyone with a Hazard Level of below the minimum requirement of 4.0 attempting to transform will be painfully electrocuted 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 electrocutions, but once they have mastered it they no longer have this concern, overcoming the side effects as in the case of Ryuga Banjo and Kazumi Sawatari.


The Sclash Driver is composed of the following parts:

  • Activator Wrench (アクティベイトレンチ Akutibeito Renchi): The wrench-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 Pawā Puresurotto): 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 Zerī Tanku): 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 Variaburu Zerī') 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 Zerī Tanku Kyappu): 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 Riakuto Dainamo): 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.

Users (chronological order)

User Kamen Rider Episode Obtained Description
Kazumi Sawatari
Kamen Rider Grease
Kamen Rider Heisei Generations FINAL: Build & Ex-Aid with Legend Riders His Sclash Driver was given to him by Blood Stalk, who had stolen the blueprints from Sento. The Driver itself was built by Namba Heavy Industries Ltd., under the direction of Nariaki Utsumi.
Ryuga Banjo
Kamen Rider Cross-Z Charge
Rider Wars Start Sento finished the Driver as well as the Dragon Sclashjelly, but didn't want to use it out of fear that the Sclash Driver will be used as a weapon of warfare. The driver would later be taken by Ryuga, using it to transform into Cross-Z Charge.

Sento briefly took his Sclash Driver and tried to transform into Cross-Z Charge as well, however because his Hazard Level was not high enough, Sento received a painful electrocution from the Driver and failed the transformation.

Ryuga's Sclash Driver and the Dragon Sclashjelly were later destroyed by Soichi Isurugi with the power of Mars in episode 30.

After the New World was created, Sento took his free time to create another Sclash Driver off the screen. Ryuga used it again in Kamen Rider Heisei Generations FOREVER and after he lost in his first fight against Killbus.

Gentoku Himuro
Kamen Rider Rogue
Final Chapter: KAMEN RIDER ROGUE Gentoku's Driver was also built by Namba Heavy Industries Ltd., under the direction of Nariaki Utsumi, and delivered by Blood Stalk.
Sento Kiryu
Kamen Rider Cross-Z Charge (failed attempt)
The Golden Soldier Sento attempted to transform into Kamen Rider Cross-Z Charge using Banjo's Sclash Driver in order to take down Kamen Rider Grease, but failed due to his Hazard Level not being high enough.
Jiro Kakizawa
Kamen Rider Rogue (failed attempt)

During the test for the candidate to be Kamen Rider Rogue, Jiro and Gentoku became the last survivors. When Blood Stalk brought in the Kaisers he retrieved the Sclash Driver and the Crocodile Crack Fullbottle and attempted to transform, but failed due to his Hazard Level not being high enough and was killed. The Sclash Driver and Fullbottle were taken from his body by Gentoku, who successfully transformed into Rogue.

Behind the Scenes


The belt is voiced by Norio Wakamoto (若本 規夫 Wakamoto Norio), who previously voiced Rey Kivat and Arc Kivat in Kamen Rider Kiva: King of the Castle in the Demon World.


  • The belt's design and alternative method of initiating the transformation, while using a variant of the series collectible, parallels the Genesis Driver from Kamen Rider Gaim.
    • Kamen Rider Cross-Z would be similar to Kamen Rider Zangetsu as both Riders would make use of their respective Drivers' upgrades to take on a new form, modifying their Rider names.
      • Prior instances where it resulted in a Form Change but did not change the actual name of the given Rider have been seen in Main and Secondary Riders, starting as recently as Genm's use of the Buggle Driver, and as far back as Baron's Lemon Energy Arms.
  • Sclash is a portmanteau of "squash" and "clash".
  • Similar to the Genesis Driver users' Ride Wear possessing tubes around the head, a unique aspect of the Sclash Driver's Rider Forms incorporates the medium used in the Driver into the armor:
    • Sclashjelly-like ornaments as part of the armor for Cross-Z Charge and Grease.
    • A crack-like design from Kamen Rider Rogue's Fullbottle being incorporated into the chest and head.
    • The contents/frame of the medium influencing the design of the base armor as well as the appearance of the head and chest for the forms using either medium.
  • Roughly translated, the first part of the Driver's announcement ties into the medium used: Cross-Z Charge and Grease's, "Tsubureru! Nagareru! Afurederu!" (潰れる!流れる!溢れ出る! lit. "Crushing! Streaming! Flowing out!"), refers to the squeezing of the Sclashjellies and the jelly forming their armor, and Rogue's, "Wareru! Kuwareru! Kudake chiru!" (割れる!食われる!砕け散る! lit, "Breaking! Biting! Smashing up!"), refers to the Crocodile Crack Fullbottle being crushed in the Sclash Driver and the crocodile that bites and cracks Rogue's head. Regular biotic/abiotic Fullbottles, when crushed in the Sclash Driver, announce "Tsuburenai!" (潰れない! lit. "Not crushed!").
    • Uniquely, the transformation differs between the Sclashjelly users and Kamen Rider Rogue, with the added elements of a large crocodile head-shaped vice cracking the mid-transformation container, and the only armor that shows animation being the crocodile biting the Rider's head.
  • As with other aspects of the season drawing from previous concepts, the visual design of the Driver appears to mix elements of both the aforementioned Genesis Driver and the Mach Driver Honoh of Kamen Rider Drive.
    • The connection between the two Drivers appears as an inversion of the primarily-used Memory Drivers from Kamen Rider W, where the newer model causes corruption from the transformation item's contents, and uses one instead of two.
    • The use of a handle/rotation implement to initiate the transformation can be seen in almost all secondary Riders' Drivers starting as far back as the Accel Driver of Kamen Rider W, the design of the Sclash Driver likely incorporating aspects from all succeeding secondary Rider Drivers.
  • The Driver's side-effects that makes the users increasingly aggressive at each transformation makes it similar to the SB-333B Delta Driver.
