The Transformation Belt Evol-Driver[2] (変身ベルトエボルドライバー Henshin Beruto Eboru Doraibā) is the transformation device of Kamen Rider Evol and Kamen Rider Mad Rogue. 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 Eborubotoru).

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.[3] The Final Weapon: Evol.


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.


While transformed, Evol/Mad Rogue initiates a finishing move by turning the Vortex Lever.

Evol's finisher is the Evoltic Finish (エボルテックフィニッシュ Eborutekku Finisshu).

  • Cobra Form: This finisher has two variations:
    • 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.
    • 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.

The finisher of Evol Match forms is the Evoltic Attack (エボルテックアタック Eborutekku Atakku)[1].

Evol can 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 can combine the powers of the Evol-Driver and a weapon to perform a powerful finisher.

The Final Weapon: Evol Evolto's Evol Driver was originally found by Soichi Isurugi on Mars near the Pandora Box. After Soichi brought it back to Earth, Takumi Katsuragi dissassembled it and hid the parts in nascita's basement. Sento later reassembled it after being blackmailed into giving it to Evolto in exchange for Taizan Himuro. He did not intend to give the Driver to Evolto, but thanks to Utsumi's help, the Driver still went back into his hands, allowing him to transform into Kamen Rider Evol.

Behind The Scenes


The voice of Evol-Driver was provided by Tetsuo Kanao (金尾 哲夫 Kanao Tetsuo), who voiced Evolto/Blood Stalk in the series.


  • The Evol-Driver also demonstrates backwards-compatibility with regular Fullbottles.
  • The Evol-Driver's looping stand-by music is a modified version of Symphony No. 9, the symphony previously used in the opening scene of episode 29.
    • Incidentally, and somewhat ironically, this was the last symphony composed by Ludwig van Beethoven, just as the Driver is portrayed as the instrument of Evolto's endgame plans, while technically being the progenitor of all known Rider systems derived from the Nebula Gas experiments.
  • The Evol-Driver is similar to the White Wizard Driver, the first upgrade-type Driver to possess the same core aspects as its base:
    • Uses the same type of trinkets to transform.
    • Most of the older trinkets have different announcements with the new Driver.
    • Used primarily by an antagonist that pretended to be an ally.
    • Produces more power than its base due to the background of the wielder.
    • Ending announcements for transformations and finishers reference the background of the user.
  • Like the Mach Driver Honoh, the Evol Driver announces most of the inserted Fullbottles in the opposite language as the Build Driver counterpart, so that if the Bottle name in the Build Driver is in Japanese, the Evol-Driver will announce it in English and vice versa. Examples include[4]:
  • Diamond = Houseki (宝石 Hōseki, lit."Jewel")
  • Comic = Manga (マンガ)
  • Taka = Hawk (ホーク Hōku)
  • Gatling = Kikanhou (機関砲 Kikanhō, lit. "Machine cannon")
  • Lion = Shishi (獅子 lit. "Lion")
  • Soujiki = Cleaner (クリーナー Kurīnā)
  • Harinezumi = Hedgehog (ヘッジホッグ Hejjihoggu)
  • Syoubousya = Fire Rescue (ファイヤーレスキュー Faiyā Resukyū)
  • Kaizoku = Pirate (パイレーツ Pairētsu)
  • Densya = Train (トレーン Torēn)
  • Octopus = Tako ( lit. "Octopus")
  • Light = Denki (電気 lit. "Electricity")
  • Phoenix = Fushichou (不死鳥 lit. "Phoenix")
  • Wolf = Ookami ( lit. "Wolf")
  • Smapho = Keitai Denwa (携帯電話 lit. "Mobile phone")
  • Unicorn = Ikkakujuu (一角獣 lit. "Unicorn")
  • Keshigomu = Eraser (イレイサー Irēsā)

  • Kabutomushi = Beetle (ビートル Bītoru)
  • Dog = Inu ( lit. "Dog")
  • Spider = Kumo (蜘蛛 lit. "Spider")
  • Reizoko = Ice Box (アイスボックス Aisu Bokkusu)
  • Kujira = Whale (ホエール Hoēru)
  • Jet = Hikouki (飛行機 lit. "Airplane")
  • Shika = Deer (ディアー Diā)
  • Tora = Tiger (タイガー Taigā)
  • Kirin = Giraffe (ジラフ Jirafu)
  • Senpuki = Fan (ファン)
  • Same = Shark (シャーク Shāku)
  • Sai = Rhino (ライノ Raino)
  • Bat = Koumori (コウモリ lit. "Bat")
  • Engine = Hatsudouki (発動機 lit. "Prime mover")
  • Hachi = Bee (ビー )
  • Sensuikan = Submarine (サブマリン Sabumarin)
  • Magnet = Jishaku (磁石 lit. "Magnet")
  • Kamen Rider = Rider System (仮面)

  • Separate Legend Rider Fullbottles are announced in the opposite language:
  • Doctor = Isha (医者 lit. "Doctor")
  • Mahoutsukai = Wizard (ウイザード Uizādo)
  • Yujou = Friendship (フレンドシップ Furendoshippu)

  • Bat = Koumori (コウモリ lit. "Bat")

  • Gear Remocon = Remote Controller (リモートコントローラー Rimōto Kontorōrā)
  • Crocodile Crack = Wani (ワニ Lit. "Crocodile")
  • Castle = Shiro ( Lit. "Castle")
  • Fukurou = Owl (オウル Ouru)
  • Kuwagata = Stag Beetle (スタッグビートル Sutagu Bītoru)
  • Hammer = Tonkachi (とんかち Lit. "Hammer")
  • Shimauma = Zebra (ゼブラ Zebura)

  • When inserting a Legend Rider Fullbottle in the Evol-Driver, it will pronounce the Legend Rider's corresponding Final Form[5].

  • Unused Fullbottles:
  • Hasami = Scissors (シザース Shizāsu)
  • Kyoryu = Dinosaur (ダイノソー Dainosō)
  • Kappumen = Noodle (ヌードル Nūdoru)
  • Energy Drink = Kenkouinryou (健康飲料 lit. "Health drink")
  • Keisatsukan = Police (ポリス Porisu)

  • However, it is unknown why there are certain Fullbottles (i.e. Tank, Tantei, USB Memory, etc.) that do not follow this trend.
    • Some of them, specifically Tank, Lock, and the currently unreleased Kyoryu Fullbottle, trigger new transformation announcements for Evol when paired with the Rider Evolbottle. This could mean the release of future Evolbottles. [6]
    • Sounds for the F1, Gold, Scorpion, Kangaroo, Ichigou, Kuuga-OOO, Showa Rider and Heisei Rider Fullbottles are not included in the Evol-Driver.
