The arsenal for Fourze was initiated by Kengo's father Rokuro Utahoshiseventeen years ago (prior to the series). He was an OSTO scientist who researched the possibility of extraterrestrial life and devised the Astroswitchesseventeen years prior to the series, before the space station he worked on was destroyed, taking Kengo's father with it.
A year before the series started, Kengo Utahoshi received a letter and an Astroswitch from an anonymous person. The portal connecting to the Rabbit Hatch lunar base, which is all that remained of the destroyed OSTO complex, was opened in the locker in a abandoned club activity room when Kengo just so happened to throw the activated Switch inside. He discovered all about the Astro and Zodiarts Switches on the base and decided to follow through with his father's plans to fight the menace that is to come, expanding on the arsenal.
Tachibana has also shown a secret interest in fast-tracking the development of the Fourze arsenal, and as such has had his own rider Ryusei Sakuta, infiltrate the Kamen Rider Club. Ryusei aids the Club in some technical aspects. When he encounters technical problems beyond him, he consults Tachibana in secret (such as the case of the NS MagPhone).
Astroswitches
Much of the Fourze arsenal relies on the power of the Astroswitches. When used with the Fourze Driver, each Switch generates a specific weapon that Fourze can use for battle.
Linkup
Many items in the Fourze arsenal are linked up to the Astroswitch Kaban. The Kaban serves as a wireless computer that allows analyses, communication and other functions.
Fourze Driver
The Fourze Driver was developed to weaponize the Astro Switches. Kengo had it ready if in case the Zodiarts began attacking. When Gentaro Kisaragidiscovered its existence, and that Kengo would probably be unable to use it because of his condition, he rushed into taking on the responsibility of transforming into Fourze, to Kengo's protests.
NS MagPhone
The NS MagPhone was designed by Kengo and created by Ryusei when it became apparent that using the Magnet Switches alone would yield disastrous results. The NS MagPhone allows for power offset, rendeing the magnetic power of the Switches manageable.
Astroswitch Modules
When Astroswitches are used with the Fourze Driver, the limb module for which the slot corresponds to generates that particular switch's weapon. Multiple Switches may be used so long as the slot is not occupied or operational.
Elek Module Billy the Rod
The Elek Module Billy the Rod comes with Elek States, accessed through the powers of the 10th Astroswitch, Elek. It's a lightningrod-like device that behaves like a sword, with a cord and plug attached to the device. By plugging this into the three sockets on Billy the Rod, it allows three methods on how to release electricity.
Fire Module Hea-Hackgun
The Fire Module Hea-Hackgun comes with Fire States, accessed through the powers of the 20th Astroswitch, Fire. It's both a fire extinguisher looking weapon that has two modes: one which puts out fires, and one that starts them. This is done by pulling apart the Module.
N and S Magnet Cannons
The N and S Magnet Cannons are built into Magnet States, accessed through the powers of the 30th and 31st Astroswitches, N Magnet and S Magnet. They serve as a pair of cannons that rest on the shoulders. On the arms are the magentic bar-like Magnet Modules, which emits a powerful magnetic field
Cosmic Module Barizun Sword
The Cosmic Module Barizun Sword comes with Cosmic States, accessed through the powers of the 40th Astroswitch, Cosmic. It is a large melee weapon that can deal both blunt-force damage and cutting damage due to the weapon being capable of switching modes, as well as built-in boosters to blast Fourze and a Zodiarts into the atmosphere without the PowerDizer.
Machine Massigler
The Machine Massigler is Fourze's Rider Machine.
Powerdizer
The Powerdizer is a robotic powerhouse used by Shun Daimonji to aid Fourze in battle. It requires strength and resistance for it to be properly used, something the previous pilots lacked.
Fourze's Astroswitches
Rocket Switch (ロケットスイッチ, Roketto Suitchi, Circle): The Rocket Switch arms Fourze with the Rocket Module (ロケットモジュール, Rokketto Mojūru) on his right arm, allowing him to fly. By using the exhaust ports on the Rocket Module, Fourze can add 40 additional tons to his punches. He had the inital problem of unable to control the Rocket Module's ports.
Launcher Switch (ランチャースイッチ, Ranchā Suitchi, Cross): The Launcher Switch arms Fourze with the Launcher Module (ランチャーモジュール, Ranchā Mojūru) on his right leg, allowing him to attack enemies from a far distance. The module can launch 5 missiles to attack an enemy, though with improper handling, the flight pattern of the missiles can be very chaotic. During the Aries Zodiarts incident, this Astroswitch was rendered useless after Aries cuts it off from the Fourze System.
Drill Switch (ドリルスイッチ, Doriru Suitchi, Triangle): The Drill Switch arms Fourze with the Drill Module (ドリルモジュール, Doriru Mojūru) on his left leg, allowing him to drill through the ground and pierce enemies with a powerful kick, though it limits his movements. It spins around 200 RPM.
Magic Hand Switch (マジックハンドスイッチ, Majikku Hando Suicchi, Circle): The Magic Hand Switch arms Fourze with the Magic Hand Module (マジックハンドモジュール, Majikku Hando Mojūru) on his right arm allowing him to use a large manipulator arm which gives him an extra 10 meters of reach and pick up heavy objects using the End Effect Pench (エンドエフェクトペンチ, Endo Efekuto Penchi).
Camera Switch (カメラスイッチ, Kamera Suitchi, Square): The Camera Switch arms Fourze with the Camera Module (カメラモジュール, Kamera Mojūru) on his left arm, allowing him to view far distances and see things that normally isn't noticed. It can also receive data from the environment nearby. The Camera Switch is generally used to operate the Burgermeal, though it is implied there are other Burgermeals being look out without the use of the Camera Switch. Also, the Module is more powerful than a Burgermeal.
Parachute Switch (パラシュートスイッチ, Parashūto Suitchi, Square): The Parachute Switch arms Fourze with the Parachute Module (パラシュートモジュール, Parashūto Mojūru) on his left arm, allowing him to deploy three parachutes to land safely to the ground if in freefall from a signifigant height. When the parachutes are not in use, thay are stored in the dark green box on Kamen Rider Fourze's arm.
Chainsaw Switch (チェーンソースイッチ, Chēnsō Suitchi, Cross): The Chainsaw switch arms Fourze with the Chainsaw Module (チェーンソーモジュール,Chēnsō Mojūru) on his right leg, allowing him to use the saw on his foot that has a powerful engine that can rotate the blade up to 15,000 rounds per minute, cutting into even the toughest of Zodiarts armor. Because the blade is on the foot, maneuverability is an issue to make sure Fourze doesn't cut himself.
Hopping Switch (ホッピングスイッチ, Hoppingu Suitchi, Triangle): The Hopping Switch arms Fourze with the pogo stick-like Hopping Module (ホッピングモジュール, Hoppingu Mojūru) on his left leg, allowing him to to significantly increase his maximum jumping height from 20 meters to 40 meters. However, this Module is unpredictable and great control is needed to use this Module properly.
Elek Switch (エレキスイッチ, Ereki Suitchi, Circle): The Elek Switch arms Fourze with 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). Initially, it just changed his right forearm's color to gold and armed him with just Billy the Rod and suffered backlash shock from the power, but after allowing the Elek Switch's power to course into Fourze's body, it allows Fourze to assume Elek States.
Scissors Switch (シザーススイッチ, Shizāsu Suitchi, Square): The Scissors Switch arms Fourze with the arts-and-crafts-looking Scissors Module (シザースモジュール, Shizāsu Mojūru) on his left arm, which allows him to cut though even metal. If the second opening of the show is any indication, it can also fire a pulse of energy for a long-range attack. The Scissors Switch is generally used to operate the Potechokin.
Beat Switch (ビートスイッチ, Bīto Suitchi, Cross): The Beat Switch arms Fourze with the Beat Module (ビートモジュール, Bīto Mojūru) on his right leg, resembling a small subwoofer that can produce sonic waves with a range of 20Hz-5kHz and a tweeter with a range of 5kHz-24kHz. A rather hilarious aspect of the Beat Module is that it can behave much like a normal subwoofer.
Chain Array Switch (チェーンアレイスイッチ, Chēn Arei Suitchi, Circle): The Chain Array Switch arms Fourze with the Chain Array Module (チェーンアレイモジュール, Chēn Arei Mojūru) on his right arm, which is a glorified spiked flail. The steel ball on the end of the chain is called the Blowing Star (ブローイングスター,Burōingu Sutā), weighing about 120 kg. The Rough Spikers (ラフスパイカー, Rafu Supaikā) on the Blowing Star are made from a newly discovered metal known as Astorium (アストリウム<, Asutoriumu). It seems old-fashioned and low-tech, but it gets the job done in handling Zodiarts. The Chain Array's links can also stretch. Like any chained weapon, inertia is a factor to make sure Fourze doesn't end up smacking the Module into himself, and there is also the chance of the Module being reflected back onto Fourze.
Smoke Switch (スモークスイッチ, Sumōku Suitchi, Cross): The Smoke Switch arms Fourze with the Smoke Module (スモークモジュール, Sumōku Mojūru), allowing him to emit smoke within a 5 mile radius for 5 minutes which can obstruct an opponent's vision in close combat, not to mention disorientate said opponent from the choking smoke.
Spike Switch (スパイクスイッチ, Supaiku Suitchi, Triangle): The Spike Switch arms Fourze with the leg-brace of the Spike Module (スパイクモジュール,Supaiku Mojūru) on his left leg, giving Kamen Rider Fourze an advantage in close-range kicks. The Spike Module consists of Rough Spikers, again made out of Astorium, only they extend a good two feet seconds before impact for maximum damage/penetration. It is also quite heavy, as Fourze had to use both arms to lift his leg out of a foot-deep hole speculated to be caused by the Spike Module, as it happened off-screen.
Winch Switch (ウインチスイッチ, Uinchi Suitchi, Square): The Winch Switch arms Fourze with the drum-style Winch Module (ウインチモジュール, Uinchi Mojūru) on his left arm, which has a spinning turbine. The Winch Module'sBoost Hooker (ブーストフッカー, Būsuto Fukkā) shoots out at high speed and can pull objects with up to 5 tons.
Flash Switch (フラッシュスイッチ, Furasshu Suitchi, Circle): The Flash Switch arms Fourze with the Flash Module (フラッシュモジュール, Furasshu Mojūru) on his right arm, allowing Kamen Rider Fourze to blind enemies (or anybody else for that matter, including himself) with the light of the sun at full power. Fourze can also control the intensity of the Flash Module's light, so he can use it like a flashlight. The Flash Switch is generally used for the Flashake Foodroid.
Shield Switch (シールドスイッチ, Shīrudo Suitchi, Square): The Sheild Switch arms Fourze with the Lockheed Martin X-33-looking Shield Module (シールドモジュール, Shīrudo Mojūru) on his left arm, allowing him to protect himself from any attack, though it is rather small in size. The Shield Module is also made from Astorium. Despite this, the Shield Module was rendered useless in future fights with the Cancer Zodiarts, as it's claw arm cleaved the Module in half.
Gatling Switch (ガトリングスイッチ, Gatoringu Suitchi, Triangle): The Gatling Switch arms Fourze with the Gatling Module (ガトリングモジュール, Gatoringu Mojūru) on his left leg, allowing Kamen Rider Fourze to shoot 10 rounds per second. The bullets have enough power to pierce into concrete.
Fire Switch (ファイアースイッチ, Faiyā Suitchi, Circle): The Fire Switch allows Fourze to enter Fire States and arms him with the Fire Module Hea-Hackgun(ファイヤーモジュール ヒーハックガン, Faiyā Mojūru Hīhakku Gan). Having learned from the Elek Switch, Fourze had no problem accessing Fire States. The Fire Switch's dormant ability is to absorb heat-based attacks to enhance it's own.
Stealth Switch (ステルススイッチ, Suterusu Suitchi, X): The Stealth Switch arms Fourze with the Lockheed F-117 Nighthawk-looking Stealth Module (ステルスモジュール, Suterusu Mojūru) on his right leg, allowing Fourze to become invisible for 5 seconds. It works by absorbing reflected light off of the Fourze System.
Hammer Switch (ハンマースイッチ, Hanmā Suitchi, Square): The Hammer Switch arms Fourze with the squeaky hammer-looking Hammer Module (ハンマーモジュール, Hanmā Mojūru) on his left arm (though the majority of the Module covers only his hand), allowing Fourze to do incredible damage with it. He can also slam the Module onto the ground to make a shockwave travel through the ground to floor a Zodiarts. However, if the Hammer Module hits something that's too hard to hit, the shockwave instead travels backwards, harming the user. During the Aries Zodiarts incident, this Astroswitch was rendered useless after Aries cuts it off from the Fourze System.
Water Switch (ウォータースイッチ, Uōtā Suitchi, Triangle):The Water Switch arms Kamen Rider Fourze with the faucet-looking Water Module (ウォーターモジュール, Uōtā Mojūru) on his left leg, allowing him to shoot intense streams of water from the nozzle for ranged attacks.
Medical Switch (メディカルスイッチ, Medikaru Suitchi, Square: The Medical Switch arms Kamen Rider Fourze with the med-kit looking Medical Module (メディカルモジュール, Medikaru Mojūru) on his left arm, which gives him access to various medicines made from Cosmic Energy.
Pen Switch (ペンスイッチ, Pen Suitchi, Cross): The Pen Switch arms Kamen Rider Fourze with the calligraphy brush-looking Pen Module (ペンモジュール,Pen Mojūru) on his right leg. When swung, Fourze can make three-dimensional objects on any surface from the "ink", which can serve as either improvised shields or to reveal invisible enemies after the ink hits it's mark. What the material the solidifed "ink" is made of is none other than pure carbon. It has a Limit Break, where Fourze covers the foe in the Pen Switch's ink to disable any special abilities a Zodiarts might have.
Wheel Switch (ホイールスイッチ, Hoīru Suitchi, Triangle): The Wheel Switch arms Kamen Rider Fourze with the Wheel Module (ホイールモジュール, Hoīru Mojūru) on his left leg, which gives him two wheels akin to a Segway to allow him to move at high speeds without straining himself or getting the Masshingler. It can also run up walls.
Screw Switch (スクリュースイッチ, Sukuryū Suitchi, Triangle): The Screw Switch arms Kamen Rider Fourze with the submarine-like Screw Module (スクリューモジュール, Sukuryū Mojūru) on his left leg, allowing him to propel himself underwater without tiring himself out.
Hand Switch (ハンドスイッチ, Hando Succhi, Cross): The Hand Switch arms Kamen Rider Fourze with the Hand Module (ハンドモジュール, Hando Mojūru) on his right leg, allowing him to utilize another manipulator arm, this time being used for delicate things. With concentration, the Hand Module can disassemble stuff.
Schop Switch (スコップスイッチ, Sukoppu Suitchi, Circle): The Schop Switch arms Kamen Rider Fourze with the power shovel-like Schop Module (スコップモジュール, Sukoppu Mojūru) on his right arm, allowing him to dig into the ground with ease, as well as lift an incredible amout of dirt to bury a target in a giant mound of dirt. The Schop Switch is generally used to operate the Horuwankov Foodroid.
N Magnet Switch (Nマグネットスイッチ, Enu Magunetto Suitchi, Circle): The N Magnet Switch is built into the MagPhone along with the S Magnet Switch, which allows Kamen Rider Fourze to become Magnet States. The N Magnet Switch, when used by itself, allows Kamen Rider Fourze to use the giant red-colored, north pole aligned, magnet bar-like N Magnet Module (Nマグネットモジュール, Enu Magunetto Mojūru) when it is not fully utilized. The N Magnet Module has a very powerful magnetic field, thus any metal object that can be magnetized will be attracted to Fourze's body. If the S Magnet Module is active, the N Magnet Module will be attracted and form unintentional cuffs. After it has been modified into the NS MagPhone with the S Magnet Switch, Fourze is able to control the Module and also changes into the powerful Magnet States.
S Magnet Switch (Sマグネットスイッチ, Esu Magunetto Suitchi, Square): The S Magnet Switch is built into the MagPhone along with the N Magnet Switch, which allows Kamen Rider Fourze to assume Magnet States. The S Magnet Switch, when used by itself, allows Kamen Rider Fourze to use the giant blue-colored, south pole aligned, magnet bar-like S Magnet Module (Sマグネットモジュール, Esu Magunetto Mojūru) when it is not fully utilized. The S Magnet Module has a very powerful magnetic field, thus any metal object that can be magnetized will be attracted to Fourze's body. If the N Magnet Module is active, the S Magnet Module will be attracted and form unintentional cuffs. After it has been modified into the NS MagPhone with the N Magnet Switch, Fourze is able to control the Module and also changes into the powerful Magnet States.
Freeze Switch (フリーズスイッチ, Furīzu Suitchi, Cross): The Freeze Switch arms Kamen Rider Fourze with the refrigerator-like Freeze Module (フリーズモジュール, Furīzu Mojūru) on his right leg, which allows him to emit super cold vapors to freeze liquids in a mere instant. It is generally used to operate the Softonya Foodroid.
Claw Switch (クローモッチ,, Kurō Suitchi, Circle): The Claw Switch arms Kamen Rider Fourze with the triclaw-like Claw Module (クローモジュール, Kurō Mojūru) on his right arm, allowing him to cleave into enemies. It can also serve as a decent shield against melee attacks.
Board Switch (ボードスイッチ, Bōdo Suitchi, Triangle): The Board Switch arms Kamen Rider Fourze with the snowboard-like Board Module (ボードモジュール,Bōdo Mojūru) on his left leg, which allows Fourze to travel on the ground with no resistance at all.
Giantfoot Switch (ジャイアントフットスイッチ, Jaiantofutto Suitchi, Cross): The Giantfoot Switch arms Kamen Rider Fourze with the boot-like Giantfoot Module (ジャイアントフットモジュール, Jaiantofutto Mojūru) on his right leg, which increases his kicking power. It also allows him to focus and amplify gravity at a localized point to bring opponents down, by stomping his foot on the ground. A mirage of the Giantfoot Module appears above the opponent as a side effect, making Kamen Rider Fourze seem like he is mentally creating a construct of Cosmic Energy to crush his opponents.
Aero Switch (エアロスイッチ, Earo Suitchi, Triangle): The Aero Switch arms Kamen Rider Fourze with the turbine-like Aero Module (エアロモジュール, Earo Mojūru) on his left leg, allowing him to suck in large quantities of air so it can then be pressurized and expelled to either lift Fourze off of the ground, or direct the pressurized air at a target to disorient it from the intense winds.
Gyro Switch (ジャイロスイッチ, Jairo Suitchi, Square): The Gyro Switch arms Kamen Rider Fourze with the helicopter rotor-like Gyro Module (ジャイロモジュール, Jairo Mojūru) on his left arm, allowing him to hover into the sky. Compared to the Rocket Module, another Module that grants flight, the Gyro Module has far greater handling and control, though sacrifies speed at the same time. It is generally used to operate the Nuggegyroika.
Net Switch (ネットスイッチ, Netto Suitchi, Cross): The Net Switch arms Kamen Rider Fourze with the butterfly net-like Net Module (ネットモジュール, Netto Mojūru) on his right leg, allowing him to create a electromagnetic net to scoop up incredibly tiny objects by swinging his leg. If the tiny objects turns out to be a Zodiarts, the net will recombine the broken-up pieces and force the Zodiarts to stay together, all while binding the arms together.
Stamper Switch (スタンパースイッチ, Sutanpā Suitchi, Triangle): The Stamper Switch arms Kamen Rider Fourze with the rubber stamp-like Stamper Module(スタンパーモジュール, Sutanpā Mojūru) on his left leg. How this Module works is first Fourze would kick a Zodiarts with the Stamper, the Module boosting his kicking damage when the hydrolics kick in, leaving a "stamp" of the Kamen Rider Club logo. The "stamp", after 15 seconds, explodes with a focused blast, doing additional damage.
Cosmic Switch (コズミックスイッチ, Kozumikku Suitchi, Circle): The Cosmic Switch arms Kamen Rider Fourze with the Cosmic Module Barizun Sword. However, in it's first testing, the Switch would not even go into the Driver, and shorted out when Gentaro pressed the big red button it has one too many times, triggering an explosion. Once Gentaro was brought to life with this Switch, the Cosmic Swich allows Fourze to transform into Cosmic States.
S-1. Rocket Switch Super-1 (ロケットスイッチスーパーワン, Roketto Suitchi Sūpā Wan, Circle): The Rocket Switch Super-1 allows Kamen Rider Fourze to use two Rocket Modules while assuming Rocket States. This special Switch is created by Kamen Rider Nadeshiko, originally using it as her personal Rocket Switch prior to Kannagi converting her into the SOLU Switch. Even after Super Galaxy King's destruction and Nadeshiko leaving Earth as a sentient energy being, Gentaro kept the Rocket Switch Super-1 on his person. The Rocket Switch Super-1 is later used, along with the Drill Switch Super-3, to arm the two Rocket Modules to Go-BusterOh's arms.
#1 Switch (1号 スイッチ, Ichigō Suitchi, Cross): The #1 Switch arms Kamen Rider Fourze with the #1 Module (1号モジュール, Ichigō Mojūru) on his right leg, boosting his kicking power and jumping height.
