Base States (ベースステイツ, Bēsu Suteitsu) is Kamen Rider Fourze's white/default form. This States can be accessed without any specific Astroswitch. On his back that is kept in all of his forms is a hoverpack, which he uses it to either keep him afloat, or to extend his jumps. By using the Rocket and Drill Modules, Base States Fourze can perform the Rocket Drill Kick (ロケットドリルキック, Roketto Doriru Kikku) Limit Break.

However, after he accepts the title of "Kamen Rider", he renames it to include "Rider" in the name for the Rider Rocket Drill Kick (ライダーロケットドリルキック, Raidā Roketto Doriru Kikku). A variation of this is the Rider Rocket Drill Space Kick (ライダーロケットドリル宇宙キック, Roketto Doriru Uchū Kikku) which is performed outside of Earth's atmosphere from transportation of the Massigler.

When pushing the Enter Lever a second time while still under the power of the first Limit Break, Fourze can perform the Rider Rocket Drill Great Space Kick (ライダロケトドリル大宇宙キック, Raidā Roketto Doriru Dai Uchū Kikku) Double Limit Break, where the auras around the Rocket and Drill Modules are enlarged and allowing Fourze to bore through things his initial Limit Break couldn't do before, but it depletes the Cosmic Energy inside the Switches and needs time to fully recharge.

Elek States (エレキステイツ, Ereki Suteitsu) is Kamen Rider Fourze's golden form accessed by the powers of the Elek Switch. In Elek States, Fourze is able to control electricity and use the Elek Module Billy the Rod (エレキモジュール ビリーザロッド, Ereki Mojūru Birīza Roddo). Elek States' offensive powers are exactly the same as Base States, but it has greater defense and its weight has been increased to 97 kg.. Kamen Rider Fourze is initially unable to activate Elek States during the first use of the Elek Switch, due to not being familiar with the Switch's States-changing powers, causing its electrical abilities to backfire onto him. After Gentaro's experience in befriending JK, he realizes that he has to "befriend" the Elek Switch, enabling the transformation into Elek States without any unwanted side-effects. This debuted in episode 6.

Aside from transforming Fourze into the Elek States, the Elek Switch can also cause a Limit Break by inserting it into the base of Billy the Rod's handle. By doing so, Kamen Rider Fourze can initiate the Rider 10 Billion Volt Break (ライダー100億ボルトブレイク, Raidā Hyaku Oku Boruto Bureiku) Limit Break. However, by setting in the Elek Switch into Billy The Rod's base and setting the plug in the top socket, Fourze can initiate the sword beam attack called Rider Ten Billion Volt Shoot (ライダー100億ボルトシュート, Raidā Hyaku Oku Boruto Shūto) Limit Break. However, if the Elek Switch is flipped off while in the Billy the Rod, it would cancel out the Elek States and turn Fourze back into his Base States.

The alternative Limit Break for Elek States is a Rider Kick called the Rider Lightning Drill Kick (ライダー電光ドリルキック, Raidā Denkō Doriru Kikku), where the Billy the Rod sends massive currents of electricity to the Drill Module.

With Billy The Rod and the Winch Module, Kamen Rider Fourze can perform the Rider Electric Shock (ライダー電気ショック, Raidā Denki Shokku) attack by striking the Winch's cable with Billy the Rod while the Rod's cable is in the left socket.

Elek Module Billy the Rod

The Elek Module Billy the Rod (エレキモジュール ビリーザロッド, Ereki Mojūru Birīza Roddo) is a lightning rod-like Module accessed by the Elek Switch to fuction as a sword. Along the crossguard is a series of sockets for a built-in plug on the Module to access different ways to unleash a eletrical current into an attack, arranged into a triangle formation.

The left socket energizes the blade, electrifying anything it hits for extra damage. The top socket energizes the blade, but it fires energy slashes when swung, allowing for ranged attacks. The right socket, when the blade is swung, sends three pulses of electricity to immobilize a Zodiarts.

By setting in the Elek Switch into Billy The Rod's base and setting the plug in the left socket, Fourze can initiate the Rider Ten Billion Volt Break (ライダー100億ボルトブレイク, Raidā Hyaku Oku Boruto Bureiku) Rider Slash Limit Break.

By setting in the Elek Switch into Billy The Rod's base and setting the plug in the top socket, Fourze can initiate the Rider Ten Billion Volt Shoot (ライダー100億ボルトシュート, Raidā Hyaku Oku Boruto Shūto) Limit Break, where the swing sends an arc of electricity with enough force to slash through the target with ease. Even the edges of the attack can do damage, as it's first usage had left environmental damage in the pavement.

By setting in the Elek Switch into Billy The Rod's base and setting the plug in the right socket, Fourze can initiate the Rider Ten Billion Volt Blast (ライダー100億ボルトブラスト, Raidā Hyaku Oku Boruto Burasuto) Limit Break, where Fourze slams the tip of Billy The Rod into the ground, sending massive voltage into the ground, destroying it while disorientating/electrocuting the target.

  • Maximum Jump Height: 17 meters
  • Maximum Running Speed: 100 meters per 6.5 seconds

Fire States (ファイヤーステイツ, Faiyā Suteitsu) is Kamen Rider Fourze's red form accessed by the powers of the Fire Switch. In Fire States, Fourze is able to use the Fire Module Hee-Hackgun (ファイヤーモジュール ヒーハックガン, Faiyā Mojūru Hīhakku Gan) which can change into Flame Mode (火炎モード, Kaen Mōdo) to be able to shoot fire, and Fire Extinguisher Mode (消火モード, Shōka Mōdo), where it can shoot fire-dousing foam. Fire States shows an increase in punching and kicking power, but sufffers a loss of jumping height and its running speed is slower.

During the fight with the Alter Zodiarts, much like pyrokinesis was the dormant power of the Ara constellation's Cosmic Energy, the dormant power of the Fire Switch's Cosmic Energy is to absorb heat-based attacks and store the power into the Switch

Like the Elek Switch, the Fire Switch can cause a Limit Break by inserting it in front of the first hand grip on the Hee-Hackgun, though unlike Elek States, Fire States has two Module-induced Limit Breaks: an unnamed one in Fire Extinguisher Mode that shot out water like a fire hose, and the Rider Exploding Shoot (ライダー縛熱シュート, Raidā Bakunetsu Shūto) Limit Break, where Fourze releases pent-up thermal energy in the Fire Switch in a powerful fiery blast from the Hee-Hackgun.

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 to multiple targets. This form debuted in Episode 9.

Like Elek States, care must be taken when the Fire Switch is inserted into the Hee-Hackgun, as switching off the Fire Switch while in the Fire Module will result in Fourze being reverted back into Base States.

Hee-Hackgun

The Fire Module Hee-Hackgun (ファイヤーモジュール ヒーハックガン, Faiyā Mojūru Hīhakku Gan) is a firearm-like Module accessed by the Fire Switch, enabling Kamen Rider Fourze to use it as a fireball launcher in Flame Mode (火炎モード, Kaen Mōdo) or shoot fire-dousing foam in Fire Extinguisher Mode (消火モード, Shōka Mōdo).

On the toy Hee-Hackgun's box, it oddly refers to the different modes (in English letters) as "Flame Gun Mode" and "Quench Gun Mode".

Fire Extinguisher Mode is accessed when Fourze attaches the Hee-Hackgun to his belt, then pulled on it to get the front half to extend out via tubing to excude fire-dousing foam. The Limit Break in this Mode is unnamed, but it consists of Fourze firing water out of the Hee-Hackgun's nozzle like a fire hose.

By setting the Fire Switch into the Hee-Hackgun while in Flame Mode, Kamen Rider Fourze can initiate the Rider Exploding Shoot (ライダー縛熱シュート, Raidā Bakunetsu Shūto) Rider Shooting Limit Break, where he either absorbs nearby thermal energy or channels pent-up absorbed thermal energy from the opponent's fiery attacks from within the Fire Switch before releasing it in a powerful fiery blast from the Hee-Hackgun.

Rocket States (ロケットステイツ, Roketto Suteitsu) is Kamen Rider Fourze's orange form accessed by the Rocket Switch Super-1, arming him with two Rocket Modules on both arms. Fourze Rocket States first appears in Kamen Rider × Kamen Rider Fourze & OOO: Movie War Mega Max when Nadeshiko creates the S-1 Switch in her final moments with a physical body so that Gentaro may combat Lem Kannagi.

This appears for the first time in the series in Episode 41, as Gentaro loses the ability to use Cosmic States due to Virgo throwing the members of the Kamen Rider Club into a state of depression, via intimidation tactics. Tachibana arrives on earth, equipped with a jetpack, and teaches him new ways to fight. Seeing no other way to catch him, Gentaro, remembering Nadeshiko as he takes out the Switch, transforms into Rocket States and catches Tachibana, only to find out that Tachibana is another identity of Virgo.

This States has shown the ability to perform two Limit Breaks, both of which are Rider Kicks. One is a corkscrew kick called the Rider Tailspin Crusher (ライダーきりもみ降下クラッシャー, Raidā Kirimomikōka Kurasshā), which is the default Limit Break.

With the Drill Module, Fourze can pull off the Rider Double Rocket Drill Kick (ライダーダブルロケットドリルキック, Raidā Daburu Roketto Doriru Kikku), which is a stronger version of Base States' Rider Rocket Drill Kick.

• Height: 212 cm.
• Weight: 114 kg.
• Rider Stats
  • Punching Power: 2.8 tons
  • Kicking Power: 6.4 tons
  • Maximum Jump Height: 13 m.
  • Maximum Running Speed: 100 m. per 6.8 seconds

Magnet States (マグネットステイツ, Magunetto Suteitsu) is Kamen Rider Fourze's silver form accessed by the NS MagPhone, which splits into the two Magnet Switches: the N Magnet Switch and the S Magnet Switch.

In terms of raw power, Magnet States is the strongest States. Kamen Rider Fourze's head becomes larger and extends to his shoulders. The orange Thermo Rejistyle (サーモレジスタイル, Sāmo Rejisutairu) stripes that is on his chest in Base States becomes red on the right side and blue on the left. The apparatus on his back in Base, Elek, and Fire States is upgraded to full-on boosters, most likely to lift the top-heavy armory of Magnet States.

However, the design of Magnet States is the downfall of this States Change. As it takes up both Arm Basements, it limits Gentaro to use Leg Basement Switches. It should also be noted that Magnet States works best firing it's cannons from a distance, as a strong enough close-combat combatant can overpower Magnet States.

In Magnet States, Fourze have the ability to manipulate magnetism with the N Magnet Module (Nマグネットモジュール, Enu Magunetto Mojūru) and S Magnet Module (Sマグネットモジュール, Esu Magunetto Mojūru) on the right and left arm respectively and use the N Magnet Cannon (Nマグネットキャノン, Enu Magunetto Kyanon) and S Magnet Cannon (Sマグネットキャノン, Esu Magunetto Kyanon) which are equipped/placed on his left and right shoulders respectively to fire bolts of electromagnetism akin to a rail gun, which the movement is controlled by the NS MagPhone that has split into the Magnet Switches to be serve as joysticks in the Fourze Driver. The joysticks also have the triggers, allowing Fourze to fire the Cannons.

Fourze can detach the two Cannons from his shoulders by pulling the Enter Lever on the Driver, making the N and S Magnet Cannons combining it into the N&S MagCannon (N&Sマグキャノン, Enu ando Esu Magu Kyanon). In this form, the MagCannon can attract anything that can be magnetized, then send it towards the attacker by sharply tilting the MagPhone halves forward. It can also fire a tornado of electromagnetism at a Zodiarts. This form debuted in episode 20.

The Limit Break for Magnet States is the Rider Super Electromagnetic Bomber (ライダー超電磁ボンバー, Raidā Chō Denji Bonbā) Rider Shooting attack, which is initiated when Fourze flips the button cover on the N MagPhone half and presses the button behind it, causing the MagCannon to charge then fire a burst of electromagnetism that slam into the Zodiarts, tearing apart the "internal organs". Due to the metallic nature of the Dragon Zodiarts, the finisher had changed to envelope him, then compressed him until he imploded.

The alternative Limit Break for Magnet States is the Rider Super Electromagnetic Tackle (ライダー超電磁タックル, Raidā Chō Denji Takkuru) attack, where Fourze charges up the Magnet Cannons, then activates the hoverpacks on his pack, getting him to move forward, then slams into the target. It works best if the PowerDizer has the Zodiarts in it's grip and moves into Fourze's path.

• Height: 206 cm.
• Weight: 98 kg.
• Rider Stats
  • Punching Power: 3.5 tons
  • Kicking Power: 7.3 tons
  • Maximum Jump Height: 23 m.
  • Maximum Running Speed: 100 m. per 5.8 seconds

Cosmic States (コズミックステイツ, Kozumikku Suteitsu) is Kamen Rider Fourze's electric blue and final form, accessed by the power of the 40th and last Astroswitch, the Cosmic Switch. In Cosmic States, Fourze is able to use the Cosmic Module Barizun Sword (コズミックモジュールバリズンソード, Kozumikku Mojūru Barizun Sōdo) which can change into the club-like Boost Mode and the sword-like Slash Mode. In this form, due to it being a fusion of all 40 Astroswitches, Fourze can access to any Module by touching their respective emblems on his chest. If he touches a Astroswitch emblem on his chest without switching on any of the other Astroswitches currently in his Driver, he has the ability to summon it into his hand; in example, he can summon the Beat Switch if the Launcher Switch is currently in the Driver.

He can also combine Switches that share a Module Basement. In example, by activating Launcher in the Fourze Driver, then presses the Freeze emblem (both of which are Cross Basement Switches), the resulting combo creates ice missiles that freezes a target a few seconds after impact.

The downside of this States Change is that it is powered by Gentaro's bonds with the Kamen Rider Club, and it can't be accessed when any of his friends cut their bonds with him.

Cosmic Module Barizun Sword

The Cosmic Module Barizun Sword (コズミックモジュールバリズンソード, Kozumikku Mojūru Barizun Sōdo) is a sword-like Module accessed by the Cosmic Switch, enabling Kamen Rider Fourze to use it in either the club/rocket-like Boost Mode, or the slashing armament Slash Mode. The sword can utilize various Astroswitches, but it is only compatible with any Circle Module Basement-orientated Astroswitches, excluding the N Magnet Switch, which must always be paired with the S Magnet Switch.

By setting the Cosmic Switch into the Barizun Sword, Kamen Rider Fourze can initiate the Rider Super Galaxy Finish (ライダー超銀河フィニッシュ, Raidā Chō Ginga Finisshu) Rider Slash Limit Break. He can take the Zodiarts out into space with the Barizun Sword Boost Mode's Limit Break, which summons a portal that leads out to space and swing the Sword for a huge sword beam attack, or it could be done in the form of an enhanced slash attack.

Rocket Drill States (ロケットドリルステイツ, Roketto Doriru Suteitsu) is Kamen Rider Fourze's orange form accessed by the ability of the Clear Drill Switch, which is found by Kamen Rider Amazon in the Amazon rainforest. Its appearance is similar to Rocket States with Base States' head.

Kamen Rider Fourze is armed with the Rocket Drill Module which appears to be a combination of the Rocket and Drill Modules on his right arm. The Limit Break for Rocket Drill States is a Rider Punch called the Rider Rocket Drill Blast (ライダーロケットドリルブラス, Raidā Roketto Doriru Burasuto).

Meteor Fusion States (メテオフュージョンステイツ, Meteo Fyūjon Suteitsu) is Kamen Rider Fourze's purple form accessed by the ability of the Fusion Switch; this switch grants Fourze access to the Meteor switch, which combines the powers of the two Riders to initiate the States change. In this form, the Astroswitches have become transparent and enhanced.

Its appearance is similar to Cosmic States with a white head and elements of Kamen Rider Meteor and Meteor Storm. In this States, Kamen Rider Fourze is armed with both the Meteor Galaxy and the Cosmic Module Barizun Sword. However, what this States comes with is the ability to use Meteor's Jeet Kun Do style, making him more dangerous to his foes.

Meteor Fusion States will appear in the upcoming Fourze movie.
