An internally located secret stone named Trickster ( トリックスター, Torikkusutā) is responsible for creating the Rider suits. When used, it reads the two-dimensional data sealed within a Rider Card and uses its power to manifest the armor parts and other materials in three-dimensional form.

Decadriver ( ディケイドライバー, Dikeidoraibā): The central unit.

The Decadriver is composed of the following parts: Taking the Kamen Ride: Decade card from the Ride Booker, Tsukasa inserted it into the Decadriver, transforming for the first time to defeat the rampaging monsters. Recognizing them from her dream of Decade, she gave them to Tsukasa who was trapped in another dimension, with the items being restored as they passed through the dimensional wall. However, both items were abandoned and left to corrode before they were found by Natsumi Hikari amongst rubble during the destruction of the worlds.

The Decadriver and Ride Booker were created for Tsukasa's use, having been the Great Leader of Dai-Shocker before losing his memory. The abandoned Decadriver and Ride Booker found by Natsumi. This version can use the powers of all Heisei Riders up to Zi-O. Decade returns in Kamen Rider Zi-O with an upgraded version of the Decadriver called the Transformation Belt NeoDecadriver ( 変身ベルトネオディケイドライバー, Henshin Beruto NeoDikeidoraibā), which is colored solid magenta and bears the symbols of all 20 Heisei Riders minus Decade and Zi-O.
