The Birth Driver is Kamen Rider Birth's transformation device that uses Cell Medals instead of Core Medals. As seen in Kamen Rider OOO 10th: The Core Medal of Resurrection, by attaching the X Unit, Kamen Rider Birth can now use Ebi (Shrimp), Kani (Crab), and Sasori (Scorpion) Core Medals to transform into Kamen Rider Birth X. Form will also make an appearance in the upcoming OOO 10th: Kamen Rider Birth - Birth x Birth Secret Episode spin-off.
