Delta Drive or D:D is a 4D SystemPerformance Tip released by Takara Tomy. It debuted in Japan with the release of the BB-114 Starter Variares D:D on July 16, 2011, and in western countries with the release of the BB-114-FX Starter Pack Variares D:D in January 2013.
Delta Drive (D:D) is a round Performance Tip with a height comparable to 145. As a 4D Bottom, Delta Drive has a mode change gimmick. In the case of Delta Drive, it can manually change between three different Performance Tips which will change its performance: "Flat" for Attack, "Wide Ball" for Defense, and "Sharp" for Stamina. This grants Delta Drive versatility as the tip can be changed in between battles - however, this versatility is rendered useless due to the fact that all the available tips have been outclassed by later Performance Tips in their respective uses. Furthermore, Delta Drive is known to wobble during battle, reducing stability and stamina.
