BuildArmor

Build Armor (ビルドアーマー) is a Kamen Rider Build-based form accessed using the Build Ridewatch, invoking Kamen Rider Build's RabbitTank Form and wielding a weapon based on the Drill Crusher. When summoned it is projected in a Fullbottle then does Build's pose before getting kicked. Build Armor's shoulder pads are modeled after Empty Bottles. Depending on whether it is used by Zi-O or Geiz, the visor spells out "Build" (ビルド) in or "Build" (びるど) in  respectively.

History
Encroaching on a battle between the first eighteen Heisei Riders and numerous monsters, Sougo Tokiwa assumed the Build Armor before proceeding to seemingly wipe out all combatants. This act was witnessed by Sento Kiryu, the original Kamen Rider Build, whom had been transported to the same location as a result of experiments he had conducted with the White Pandora Panel.
