Bottle Change Rider Series

is a toyline series of action figures attached to Kamen Rider Build. Best Match Figures are designed to split in two to recreate Trial Forms, while other figures their own gimmicks: Sclash Driver users feature flip-out armour parts to replicate their transformations, RabbitTank Hazard features attachable armor parts to turn it into either RabbitRabbit or TankTank Form, and Genius Form has a chestpiece that can be rotated to change its color.

==Notes==
*The figures are compatible with the DX Build Phone.
*This lineup is similar to W Form Change toyline from Kamen Rider W as the body of the figure splits into two halves to allow for different forms.
*This is the first "gimmick" line since Wizard Action Please! to not release any additional figures via Premium Bandai, only releasing an accessory.
*Many of Build's Best Matches were not released in this line, as well as no other forms for Cross-Z, Grease and Rogue. Kamen Rider Evol and Kamen Rider MadRogue were not included at all.
