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 Gaia Memories used by the eponymous hero of Kamen Rider W, specifically Philip's green-colored Cyclone Memory. 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 USB Memory 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.
