The arsenal was originally developed by Rokuro Utahoshi for the group known as the Outer Space Technology Organization Energy. Rokuro used a hypothetical system its occupants used in ancient times to model the system after the Four Chinese constellations as reflected in the specific symbols on his limbs: Byakko, Suzaku, Seiryu, and Genbu. Mituaki Gamou compares the power to that of a gravitational lens, particularly on how the Rider influences both Astroswitches and Zodiarts Switches. After Gentaro places the Fourze Driver belt with four Astroswitches in place, he turns on the Driver by pushing all four red switches, then pushes the lever on the right side of his belt, transforming him into Kamen Rider Fourze. He can use different combinations of abilities depending on the Astroswitches he has. One of several forms are known as a States. After transforming into Kamen Rider Fourze, Gentaro shouts "Space, here I come!" and says "Kamen Rider Fourze, Let's settle this once and for all!" before battle. The suit itself also doubles as a spacesuit, allowing Kamen Rider Fourze to spacewalk, though unlike a spacesuit, he can safely reenter the earth's atmosphere without burning up. It also has a hover pack.
Base States is Kamen Rider Fourze's standard white-colored form. The Rocket, Launcher, Drill, and Radar Switches are usually used to transform into Base States, but this States can be accessed with any combination of four switches. The Limit Break finishing attack for Base States is the Rider Rocket Drill Kick. A variation of this is the Rider Rocket Drill Space Kick, which is performed outside of Earth's atmosphere, using the Massigler to be send both the Zodiarts and Fourze into lower orbit. When pushing the lever a second time, he can perform the Rider Rocket Drill Big Space Kick Double Limit Break, where the auras around the Rocket and Drill Modules are enlarged and allowing him to bore through things his initial Limit Break could not before. However, this exhausts the Cosmic Energy of the Rocket and Drill Switches rendering them inactive until they are recharged.
Elek States is his gold-colored form accessed by the Elek Switch at full power. In Elek States, he is able to control electricity and use the Billy The Rod. In addition to the Limit Breaks performed solely through Billy The Rod, Elek States can also perform the Rider Lightning Drill Kick, allowing him to use both the Billy The Rod and the Drill Module on his target, in addition to the Rider 10 Billion Volt Break. He is initially unable to activate Elek States during the first use of the it, due to not being familiar with the Switch's States-changing powers, causing its electrical abilities to backfire. After Gentaro's experience in befriending JK, he realizes that he has to "befriend" the Elek Switch, accepting the qualities that makes it what it is, even the bad ones, enabling the transformation into Elek States without any unwanted side-effects.
Fire States is his red-colored form accessed by the Fire Switch at full power. In Fire States, he wields the Hee-Hackgun, which has both fire- and water-based attacks. Kamen Rider Fourze can also absorb all fire based attacks while in Fire States into the Fire Switch, giving it more power and allowing it to release all of its stored power during its Limit Break. The ability to absorb fire was brought out due to Gentaro's attempt to befriend Tomoko and accept her qualities. He also has an unnamed Limit Break in conjunction with the Launcher and Gatling Switches where he fires a barrage of fire, missiles, and bullets.
Rocket States is Kamen Rider Fourze's orange-colored form accessed by the Rocket Switch Super-1 at full power. In Rocket States, he is armed with two Rocket Modules on both arms. This States had shown to perform two Limit Breaks, both of which are Rider Kicks. One is a corkscrew kick called the Rider Tailspin Crusher which is the default Limit Break. With the Drill Module, Fourze can pull off the Rider Double Rocket Drill Kick, which is a stronger version of Base States' Rider Rocket Drill Kick. Rocket States first appears in Kamen Rider × Kamen Rider Fourze & OOO: Movie War Mega Max. After much of the Kamen Rider Club is taken out of commission by the Virgo Zodiarts, Gentaro uses the Rocket Switch Super-1, once more, as he cannot access Cosmic States without the rest of the Kamen Rider Club.
Magnet States is his silver-covered form accessed by the NS Magphone. In this form, he has powerful electromagnetic powers, and is armed with two powerful railguns mounted on his shoulders called the N Magnet Cannon and the S Magnet Cannon. After triggering the Enter Lever, the two Magnet Cannons can detach from Fourze's shoulders and link up into the NS Magnet Cannon which can hover in midair. The NS Magnet Cannon is used in the Magnet States Limit Break to fire a powerful beam of electromagnetic energy called the Rider Super Electromagnetic Bomber that compresses the target with destructive magnetic force. A variant Limit Break includes the Launcher and Gatling Switches for additional firepower. The alternative Magnet States Limit Break is the Rider Super Electromagnetic Tackle, where he has the NS Magnet Cannon ram straight into the opponent instead. He can also use the Rider Super Electromagnetic Strike in tandem with Kamen Rider Meteor by lending him the N Magnet Switch which allows both to use the magnetic pull from each other to ram into enemies.
Cosmic States is his electric blue-covered ultimate form accessed using the Cosmic Switch, infused with all 40 Astroswitches and able to use any number of them at once. As a true manifestation of friendship, the Cosmic Switch, which initially repels the Fourze Driver, had to be forced into the Driver by Kengo with Gentaro calling forth his friendships forged thus far to unlock its power. The Switch is proven to be powerful enough to resurrect the dead Gentaro, with Cosmic States unaffected by most Horoscopes' special attacks. However, his ability to assume Cosmic States depends on maintaining the bond with the rest of his Club friends as losing even one friend, regardless of circumstances, negates the transformation and renders the Cosmic Switch unusable. It is eventually revealed that the access to this form relies mainly on Gentaro's faith in the friendship he forged, instead of the fact whether the Club is in one piece. Cosmic States has the Switching Lung on his chest, which are four touch panels with 10 Astroswitch symbols on each one, all arranged depending on their Module Basement. By touching the symbols on his chest, Fourze can conjure the power of an Astroswitch to use or augment the power of one with another (for example giving the Launcher Switch the effect of the Freeze Switch). In this form, he can also perform a warp drive and has a much more powerful exhaust in his hover pack. Even when robbed of the Barizun Sword, Cosmic States can perform a Rider Kick Limit Break, simply dubbed "Rider Kick" and consisting of a bright blue aura of Cosmic Energy forming around the right leg during a flying side kick. This makes Rider Kick Fourze's only Limit Break delivered with the right leg rather than the left.
|Rocket Drill States
Rocket Drill States is his orange form accessed by the Clear Drill Switch and the Rocket Switch. In this form, Kamen Rider Fourze is armed with the Rocket Drill Module, a combined state of the Rocket and Drill Modules, on his right arm. The Limit Break finishing attack for Rocket Drill States is a Rider Punch called the Rider Rocket Drill Blast. His appearance is similar to Rocket States with Base States' head. Rocket Drill States appears in the Kamen Rider Fourze Hyper Battle DVD.
|Meteor Fusion States
Meteor Fusion States is Kamen Rider Fourze's purple form accessed by the Meteor Switch and the Fusion Switch. In this form, Fourze gains the powers of Kamen Rider Meteor such as the use of the Meteor Galaxy as well as being able to use advanced martial arts moves like Kamen Rider Meteor. The Astroswitches become enhanced in this form and become transparent. Fourze is also capable of using the Barizun Sword in this form. The Limit Break finishing attack for Meteor Fusion States is a Rider Kick called the Rider Fusion Drill Kick, which uses the Clear Drill Module. Meteor Fusion States appears in Kamen Rider Fourze the Movie: Space, Here We Come!.
Kamen Rider Meteor Storm is Kamen Rider Meteor's blue and gold powered-up form when he uses the Meteor Storm Switch. After changing into Kamen Rider Meteor Storm, Ryusei says "Kamen Rider Meteor Storm, my fate will deliver a storm!" Kamen Rider Meteor Storm's helmet is called the Starlight Face. When using the Fire Switch, fire envelops Kamen Rider Meteor Storm's body, enabling him to manipulate the fire at his whims. He can also perform a Limit Break attack that is a variation of the Meteor Tornado.
