Kamen Rider Fourze

The arsenal of Kamen Rider Fourze is developed by the group known as the Over Space Technology Organization (外宇宙技術開発機構, Ge Uchū Gijutsu Kaihatsu Kikō, OSTO). The OSTO developed technology that enables its user to harness a mysterious form of energy called Cosmic Energy (コズミックエナジー, Kozumikku Enajī). After Gentaro inserts four Astro Switches into the Fourze Driver belt, he pulls the lever on the side of his belt, which transforms him into Kamen Rider Fourze. Gentaro took the equipment to become Kamen Rider Fourze from Kengo after he followed Kengo. Fourze is based off a space craft and roughly the retired Space Shuttle. Gentaro tends to say "Space is Here!" (宇宙キター, Uchū Kitā) when transforming into Kamen Rider Fourze and says "Let's settle this once and for all!" (タイマン張らせてもらうぜ！ Taiman harasete morau ze!) before battle. 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. The suit itself also doubles as a spacesuit, allowing Kamen Rider Fourze to spacewalk. It also has a hover pack, allowing Kamen Rider Fourze to hover in the air for a short distance. The Red-Eyed Man compares Kamen Rider Fourze's power to that of a gravitational lens, particularly on how the Kamen Rider influences both Astro Switches and Zodiarts Switches. After accepting the title of Kamen Rider, he often names his attacks with "Rider" before it.
