Behind the scenes
While not part of the 60 and beyond Fullbottles seen in the on-screen canon, this Fullbottle is clearly derived from the profession of Shotaro Hidari, Kamen Rider Joker and left half of the eponymous hero of Kamen Rider W. 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 Tantei Fullbottle would constitute part of the "essence" of Double. The complete W Fullbottle, however, as yet only exists as a sound in the DX Build Driver.
