Gentaro is given the equipment to become Kamen Rider Fourze by Kengo. Fourze is based off a space craft and roughly the retired Space Shuttle. After Gentaro inserts four Astro Switch into the Fourze Driver Belt, then he pulls the lever on the side of his belt, and he transforms into Kamen Rider Fourze. Gentaro tends to say "Space is Here!" (宇宙キター, Uchū Kitā^?) when transforming into Kamen Rider Fourze. Similar to his predecessors, Kamen Rider Double and OOO, Fourze uses combinations with the Astro Switches and their modules. However unlike the Gaia Memories and O Medals, only a few of the Astro Switches changes Fourze into a different form (known as 'States'). Kamen Rider Fourze has shapes on his limbs where the Modules attach: Circle for the right arm, Cross for the right leg, Triangle for the left leg, and Square for the left arm. Kamen Rider Fourze also has a turbine on his back not only used to fly, but also used to control posture.
