Evol-Driver

The Transformation Belt Evol-Driver (変身ベルトエボルドライバー) is the transformation device of Kamen Rider Evol and Kamen Rider MadRogue. It is the basis of the weaker Build Driver and uses a variant of the Fullbottles known as the Evolbottles (エボルボトル).

The origin of Evolto's original Evol-Driver is unknown, but it was damaged when Evolto decimated Mars using the Pandora Box. However, when Soichi Isurugi first discovered the box, Evolto managed to possess him and used his body to unearth the Evol-Driver and brought it along with the box to Earth. When Shinobu Katsuragi was contacted by Evolto, he repaired it and studied it along with Evolto himself. His son, Takumi Katsuragi, eventually hid it away from Evolto, recognizing Evolto's destructive goals. Much later, Evolto bargained with Sento Kiryu to find it in exchange for Taizan Himuro's life. Sento discovered Shinobu's hidden research and recognized the Evol-Driver as the power source for the Fullbottle-purifying device that he built, retrieving it and reassembling it. With the help of Gentoku Himuro, Sento and the other Riders planned to save Taizan without giving the Evol-Driver to Evolto, but Nariaki Utsumi managed to steal it out of Misora Isurugi's hands and threw it to Evolto. According to the research of Shinobu Katsuragi, a Hazard Level of 5 is a required to transform using the Evol-Driver, a level unattainable using conventional means. He also describes the Evol-Driver as being able to consume the power of the Pandora Box and control the universe. .

Functionality
Similarly to the Build Driver, Kamen Rider Evol transforms by inserting two Evolbottles into the Evol-Driver and cranking the lever. Unlike the Build Driver's Best Match combinations of two paired Fullbottles, Evol accesses his forms using the Rider Evolbottle along with any other Evolbottle to access a Rider form themed after the varying Evolbottle used. The Evol-Driver is still capable of using normal Fullbottles to transform into a Rider form in the same way as the Build Driver, and also recognizes Best Matches, as seen with Kamen Rider Mad Rogue transforming using the Bat and Engine Fullbottles.

It is unknown why the forms accessed with the Evol-Driver do not utilize Halfbodies in their construction. While Evol, using Evolbottles, features the diagonal undersuit of Halfbodies, Mad Rogue does not. The transformations differ from the Build Driver, as well, as Evol still shows a similar construct to the Snap Ride Builder, while Mad Rogue's appears as an interconnected mass of tubing.

Finishers
While transformed, Evol/MadRogue initiates a finishing move by turning the Vortex Lever.

Evolution forms= Evol's finisher in his normal forms is the Evoltic Finish (エボルテックフィニッシュ).
 * Cobra Form: This finisher has two variations:
 * Rider Kick: Evol generates an energy star map beneath his feet that then transforms into a dark red and dark blue energy galaxy that flows into his right foot before delivering an explosive kick.
 * Rider Punch: Evol delivers a flaming punch.
 * Dragon Form: Evol coats his hand in dark blue flames before delivering a punch that projects an energy Chinese Dragon upon impact.
 * Rabbit Form: This finisher has two variations:
 * Rider Kick: Evol delivers a roundhouse kick covered in red and orange energy that generates an energy star map upon impact.
 * Rider Punch: Evol delivers a punch covered in flames and purple energy that sends the target flying.

Evol can also access finishers utilizing Fullbottles by inserting one along with his Rider Evolbottle. This allows him to execute a finisher attack named after the Fullbottle used.

Evol-Driver + Weapon
Evol and MadRogue can combine the powers of the Evol-Driver and a weapon to perform a powerful finisher. Hawk Gatlinger=
 * Kikanhou Finish/Full Bullet (機関砲フィニッシュ／フルバレット): Evol summons the Hawk Gatlinger and fires a stream of large energy hawks.
