Sclash Driver

The Sclash Driver is a transformation device that grants its user the power to transform into a Kamen Rider. It uses evolved forms of the Fullbottles called Sclashjellies to transform.

The Driver was first conceptualized by scientist Takumi Katsuragi and completed by Sento Kiryu. It was originally intended by Sento to be used by Ryuga to transform into Kamen Rider Cross-Z Charge though it's schematics were later copied by Evolt and used to create the Kamen Riders Grease and Rogue.
