Behind the scenes

Fourze Fullbottle

Fourze Fullbottle

While not part of the 60 and beyond Fullbottles seen in the on-screen canon, this Fullbottle is clearly derived from the personality of Gentaro Kisaragi, the eponymous hero of Kamen Rider Fourze. Following the example set in Kamen Rider Ex-Aid: True Ending and the subsequent Kamen Rider Heisei Generations FINAL: Build & Ex-Aid with Legend Riders, the Yujou Fullbottle would constitute part of the "essence" of Kamen Rider Fourze. The complete Fourze Fullbottle is paired with that of Kamen Rider Wizard in the toyline.
