Kamen Rider Double

"Now, count up your sins/crimes!"

- announcement before battle.

Kamen Rider Double (仮面ライダーダブル) is the main and eponymous protagonist of the Kamen Rider Series Kamen Rider W. Double is the first Kamen Rider that transforms from two people. Double made his debut appearance in the film Kamen Rider Decade: All Riders vs. Dai-Shocker.

Shotaro Hidari
The left half of Double providing the 'body' (except when changing into FangJoker, where he becomes the 'mind'), Shotaro is a self-dubbed Hard-boiled Detective. He is also a Kamen Rider on his own as Kamen Rider Joker.

Philip
The right half of Double providing the 'mind' (except when changing into FangJoker, where he becomes the 'body'), Philip disappeared after being broken down into data but came back a year later, thanks to his mother and sister. In the novel, Philip assumes the role of a Kamen Rider on his own as Kamen Rider Cyclone.

All Riders vs. Dai-Shocker
In Double's debut appearance, he simply arrives on the scene riding the HardBoilder, already transformed, as Decade and Kuuga Rising Ultimate having difficulty fighting Shadow Moon. As he stops in between them, Shadow Moon sees him from the left, commenting that he's a black Rider; Decade, however, sees him from the right, thinking he's a green Rider instead. Double shows off his Memory-changing abilities by using first HeatJoker and then HeatMetal, sending Shadow Moon flying into the side of Shocker's fortress with a blow from his staff. He then returns to CycloneJoker form and leaves, Shotaro complaining about having to leave 'before the good part'.

It is interesting to note that, in this first appearance, Double's right eye does not flash when only Phillip is speaking, in contrast to his later appearances, presumably because this quirk had not yet been decided on.

In the manga adaptation of All Riders vs. Dai-Shocker, based on the original script when the movie was planned to be the original ending of the TV series, Kamen Rider Double does not appear at all and it is Decade and Kuuga who defeat Shadow Moon.

Let's Go Kamen Riders
"Let's go, Philip! OK, Shotaro."

- Shotaro and Philip prepare to fight once more Philip and Shotaro appeared after the three 90s riders and the first eight Heisei riders and Decade, coming to the assistance of the Master of Fumen, who was being attacked by Shocker Combatmen and various Dopants.

After the riders were united, they faced off against Shocker's Great Leader. Later, when joined by a force of extra riders, Double and all the other riders got on their motorcycles and performed the "All Rider Break", ramming into the Rock Great Leader and defeating it once and for all.

Movie War Mega Max
Initially, Double doesn't show up together in Mega Max. Shotaro finds members of Foundation X attempting to steal away a container holding SOLU and prepares to transform into Double. However, Philip's preoccupied with recipe hunting, so Shotaro opts for just Kamen Rider Joker. Shotaro and Philip arrive soon after at Eiji's request, aiding Gentaro Kisaragi in his attempt to stop Super Galaxy King from completing his plans, staying behind to hold off some of Foundation X's goons. After Double finishes off the Zodiarts, they then witness the destruction of Exodus and congratulate the new Riders.

Super Hero Taisen
Double is one of the Riders who answers what seemed like Kamen Rider 1's call and joins his force to attack the Super Sentai force led by Akaranger in order to preserve the existence of the Kamen Riders. Using their bike, the HardBoilder, alongside Kabuto and Kiva, Double attacks the Zyurangers and Megaranger. However, afterwards he attempts to engage Akaranger in combat alongside Kiva only to be seemingly destroyed by his attack.

However, that was all part of Tsukasa's and Captain Marvelous's plan. They had disguised themselves as Kamen Rider 1 and Akaranger and led the Super Sentai and Kamen Riders against each other to fool Dai-Shocker and Dai-Zangyack into thinking that the Riders and Sentai had been really wiped out. However, Double, alongside all the other Rider and Super Sentai forces are seemingly destroyed during the battle, but reappear from a dimensional wall to join forces and defeat the Shocker-Zangyack Alliance.

Movie War Ultimatum
Shotaro and Philip returns along with Ryu and also with Eiji and Goto in Movie Wars Ultimatum by Kamen Rider Wizard's summon ring which can summon any Kamen Rider. In Ultimatum, Double rides on his Hardboilder.

Super Hero Taisen Z
Double was part of a force of Rider and Sentai reinforcements led by Kamen Rider 1 and that came to assist the Riders and Sentai of recent years who were overwhelmed by the revived monster army of the. The combined forces of superheroes were able to turn the tide against the Madou army. They lined up and used their various finisher attacks to destroy the revived monsters.

After was destroyed and the battle was finally over, Double appeared standing on a cliff with all the other heroes who appeared to help, to say goodbye to the heroes of recent years before taking their leave.

Super Hero Taisen Otsu
Double along with Deka Red, Gavan, Rinko and Shunpei solve cases from heroes.

Kamen Rider Wizard
Double appears with all the Heisei Riders from Kuuga to Fourze, led by Decade, in a special two-parter after the finale, The Kamen Rider Rings and Neverending Story.

Kamen Rider Taisen
In Futo, Tsukasa sent Kaito to help him on his case, having the young Rider becoming displeased about it. Later, Tsukasa wants Shotaro to join the Heisei Riders to fight Badan. Shotaro refuses the offer, but he informs him about Shuu. As Black and Black RX were about to fight Tsukasa, Shotaro appears to fight them, having him taking Shuu to the lighthouse to meet with his mother. Joker would be assisted by Baron, however the Armored Rider sacrificed himself from being attacked by Amazon and Super-1. Having the remaining Riders to battle each other, Joker got himself defeated when Black and Joker performed their resopective Rider Kick on each other. However, the defeated Riders would return thanks to Gaim as they battle the Badan Empire. After battling the Badan Empire, Hongo stated that their battle wasn't over as the Rider War continues. However the Showa Riders admit their defeat after seeing Gaim protecting a flower as they would congratulate the young Riders. Sometime later, Shotaro was seen searching for a missing cat back in Futo.

Kamen Rider Battride War
Kamen Rider Double appears as a Main Rider in the video game Kamen Rider Battride War, which unites the Riders of the Heisei era from Kuuga to Wizard. After being awakened, Double must relive the memory of the final battle with the Weather Dopant to break free of the Mnemosyne (though as depicted in this game, Double finishes Isaka rather than Accel).

Double has access to his three primary forms, with the Half Changes merely being cosmetic alterations (ex.: HeatJoker and LunaJoker play-styles and normal attacks are identically to CycloneJoker and so forth). Joker Half-Changes excels at melee and aerial combos, Metal Half-Changes is slow but powerful, and Trigger Half-Changes has a variety of ranged attacks. Double's final form is naturally CycloneJokerXtreme. While returning to a primary form, the main form will be CycloneJoker. FangJoker is also in the game, possessing the ability to temporarily increase his speed in place of form changing and more advanced than Double's Joker Half-Changes.

FangJoker is a separate unlockable character, with no connection with the main Double. Renn Kiriyama reprises his role as Shotaro Hidari in Battride War, while Philip's voice overs are all stock audio from Masaki Suda's previous performances (as evidenced by only Shotaro calling the Trigger Aerobuster's name when using the attack).

Double's special attacks are:
 * Joker Half-Changes: Joker Grenade (remained into HeatJoker), Joker Strange (remained into Luna Joker), Joker Extreme (remained into CycloneJoker)
 * Metal Half-Changes: Metal Twister (remained into CycloneMetal), Metal Illusion (remained into LunaMetal), Metal Branding (remained into HeatMetal)
 * Trigger Half-Changes: Trigger Aerobuster (remained into CycloneTrigger), Trigger Explosion (remained into HeatTrigger), Trigger Full Burst (remained into LunaTrigger)
 * CycloneJokerXtreme: Double Xtreme (used upon first changing), Bicker Finallusion, Prism Break, Bicker Charge Break
 * FangJoker: Arm Fang Multi-Slash, Shoulder Fang, Arm Fang Thrust Slash, Fang Streisser

Kamen Rider: Battride War II
Kamen Rider Double reappeared in Kamen Rider: Battride War II, summoned by Cinema along with the other Neo-Heisei Riders in order to create the "ultimate movie". Double's stage was based off from Kamen Rider W Forever: A to Z/The Gaia Memories of Fate, with Kamen Rider Eternal as his main enemy.

Kamen Rider Double is one of the Kamen Riders who appeared in the crossover universe of Super Hero Generation, which included characters from the Mobile Suit Gundam and Ultraman universes. In this universe, Double can assume all his forms, including FangJoker, without canceling his base transformation.

Kamen Rider Double
When Shotaro and Philip set their Gaia Memories into the Double Driver Belt, Philip's conscious mind enters Shotaro's body to produce Double (except when they change into FangJoker, where the opposite happens). Their quote at the start of a battle is "Now, count up your sins!" (さあ、お前の罪を数えろ！), a quote originally used by their predecessor and mentor, Sokichi Narumi.

When combined as Double, Shotaro usually does most of the talking, though both speak when saying their pre-battle quote and announcing Maximum Drive attack names. When Philip speaks by himself when transformed, Double's right eye flashes. Double's ability to function is dependent on the condition of both Shotaro and Philip. If their synchronization is somehow disrupted, Kamen Rider Double will be unable to move properly. If their Rider form takes any significant amounts of damage, both of them will feel the pain after returning to normal and Philip will often pass out due to his weaker constitution. Shotaro's habit of flicking his wrist carries over to Double.

Kamen Rider Double is unique among Kamen Riders in that rather than having explicitly defined forms, he instead has mix-and-match powers, this quality only being shared by Kamen Rider OOO and Kamen Rider Drive. Through the different Gaia Memories, Double has access to various combinations of powers, weapons, strengths, and weaknesses. Kamen Rider Double's forms accessed through their first six Gaia Memories are known as Half Changes (ハーフチェンジ), due to the fact that Double can switch out one (or both) Gaia Memories in the belt in a Memory Change (メモリチェンジ) to change forms.

Each different version of Kamen Rider Double has its own finishing attack(s) known as Maximum Drives (マキシマムドライブ) which is needed to defeat a Dopant. The energy imparted by the Maximum Drive does not destroy the Dopant but rather its Gaia Memory, resulting in the ejection of the Gaia Memory from the user's body, reverting the person to normal and the destruction of the Gaia Memory, hence why such a procedure is called a Memory Break (メモリブレイク).

Double Driver
The Double Driver is Kamen Rider Double's transformation belt. It is a second generation Memory Driver after the Gaia Driver series, stolen from the Museum corporation when Philip was rescued, and uses two Gaia Memories at once for even more power for the user. There is only one, physical, Double Driver, but when Shotaro places it on him, another Double Driver manifests itself onto Philip. By inserting the Gaia Memories into the respective Memory Slots on their belt buckles, Shotaro and Philip can transform into Double. The Left Slot holds Shotaro's Gaia Memories and the Right Slot holds Philip's.

When Philip puts a Gaia Memory into the Right Slot, he undergoes Soul Forward, sending his soul to Shotaro to transform both of them into Kamen Rider Double. The only exception to this rule is Kamen Rider Double FangJoker, when Shotaro instead undergoes Soul Forward, sending his soul to Philip (with a Fang Memory) in order to transform. Another slot on the right side of the Double Driver is called the Maximum Slot. When a Memory is placed in the Maximum Slot, Double can use a Maximum Drive finisher attack. This specific slot is used for the Joker Memory to execute either the Joker Extreme (CycloneJoker), Joker Grenade (HeatJoker) or the Joker Strange (LunaJoker) Maximum Drives.

In other forms, it can be used to insert the right half's Memory, allowing for a Twin Maximum attack, but this is immensely dangerous due to the strain it puts on Shotaro's body. As long as the Double Driver is worn by both Shotaro and Philip, they can telepathically communicate with each other provided that both of them are conscious outside the transformation to Double.

Gaia Memories


The Gaia Memories (ガイアメモリ) are mysterious USBs with imbued with the powers of the Earth itself. Originally created with funding by the Sonozaki Family, these Gaia Memories end up in the possession of Shotaro and Philip.

Compared to the Gaia Memories used by Dopants, the Memories used by Kamen Rider Double are much more refined in appearance, something that Shinkuro Isaka states is indicative of the limits placed on their powers. Two can be inserted into the Double Driver, allowing Shotaro and Philip to transform into Double.

Philip's right-half Gaia Memories, called Soul Memories (ソウルメモリ), determine the elemental power of Kamen Rider Double, while Shotaro's left-half Memories, called Body Memories (ボディメモリ) determine the type of attacking style that Kamen Rider Double uses.


 * Cyclone Memory (サイクロンメモリ): The Cyclone Memory, also known as the Windy Memory (風の記憶), allows the user to move at fast speeds, controlling the very power of wind, becoming the Windy Warrior (風の戦士). When used, half of Kamen Rider Double becomes the Cyclonic Right Half (旋風の右半身). Forms using the Cyclone Memory possess a Windy Stabilizer (ウィンディスタビライザー), a silver scarf hanging from the neck. This is one of Double's most used memories, as combined with the Joker Memory it creates a balanced combination of strength and speed.
 * Joker Memory (ジョーカーメモリ): The Joker Memory, also known as the Trump Card Memory (切り札の記憶), allows the user to increase fighting potential and enhances the users reflexes significantly, becoming the Skill Warrior (技戦士). When used, half of Kamen Rider Double becomes the Trumping Left Half (切り札の左半身). When the Joker Memory is placed in the Maximum Slot on the Double Driver, it enables the Maximum Drive finisher. This Memory also can be used by Shotaro to become Kamen Rider Joker when used in the Lost Driver. This is one of Double's most used memories, as combined with the Cyclone Memory it creates a balanced combination of strength and speed.
 * Heat Memory (ヒートメモリ): The Heat Memory, also known as the Hot Memory (熱き記憶), empowers the user with the powers of the element of fire, becoming the Blazing Warrior (炎の戦士). When used, half of Kamen Rider Double becomes the Heated Right Half (熱き右半身). Double often combines this with the Metal Memory for maximum raw strength among his regular forms.First used in All Riders vs. Dai-Shocker.
 * Metal Memory (メタルメモリ): The Metal Memory, also known as either the Steel Memory (鋼鉄の記憶) or the Fighter Memory (闘士の記憶), empowers the user with great strength and magnified resistance to physical harm, becoming the Superpowered Warrior (怪力戦士). When used, half of Kamen Rider Double becomes the Fighting Spirit Left Half (闘士の左半身). As a drawback, it is very slow. When the Metal Memory is placed in the Maximum Slot on the Metal Shaft, it allows Kamen Rider Double to infuse the tips of the Metal Shaft with an elemental-powered Maximum Drive attack. Double often combines this with the Heat Memory for maximum raw strength among his regular forms. First used in All Riders vs. Dai-Shocker.
 * Luna Memory (ルナメモリ): The Luna Memory, also known as the Illusion Memory (幻想の記憶), allows the user to cast illusions, stretching limbs and bending gunshots, becoming the Mysterious Warrior (神秘の戦士). When used, half of Kamen Rider Double becomes the gold Fantastical Right Half (幻想の右半身). Due to its ability to control shot trajectory, Double often combines Luna with the Trigger Memory.
 * Trigger Memory (トリガーメモリ): The Trigger Memory, also known as the Sniper Memory (銃撃手の記憶), turns the user into an expert marksman, becoming the Gun Warrior (銃戦士). When used, half of Kamen Rider Double becomes the blue Sniping Left Half (狙撃手の左半身). When the Trigger Memory is placed in the Maximum Slot on the Trigger Magnum, it allows Kamen Rider Double to fire an elemental-powered Maximum Drive attack. Trigger is often combined with the Luna Memory due to the combination's ability to control shot trajectory.
 * Prism Memory (プリズムメモリ): The Prism Memory is a Gaia Memory for the PrismBicker sword and shield. It serves as a storage for other Gaia Memory powers and links the power of four Maximum Drives into one. Similar to the Engine Memory used by Kamen Rider Accel, it is not a true Gaia Memory, as its powers are linked to the Xtreme Memory.

Fang Memory
The Transforming Gaia Dinosaur Fang Memory (変形ガイア恐竜ファングメモリ), also known as the Fanged Memory (牙の記憶) is a special Gaia Memory that was created only to protect Philip by any means necessary, enabling him and Shotaro to transform into Kamen Rider Double. It can change between its Live Mode, which resembles a dromaeosaurus, and it's Memory Mode, the top of which resembles a dinosaur's head.

When used, half of Kamen Rider Double becomes the white Fanged Right Half (牙の右半身), enabling Double to fight like a berserker while altering the left half to match it in being animalistic in design. As it was created to protect Philip it only appears when he or anyone in his vicinity is in danger. However it does appear on its own free will during average times.

Xtreme Memory
The Transforming Gaia Bird Xtreme Memory (変形ガイア鳥エクストリームメモリ) is a special bird-like Gaia Memory that allows Kamen Rider Double to become CycloneJokerXtreme by changing from Live Mode (ライブモード) to Memory Mode (メモリモード) after sliding onto the Double Driver, as the Driver makes light rails for the Memory to slide down on.

It first appears when Philip is in mortal danger from being attacked by the Weather Dopant, and it digitizes him where Shroud confronts him about his mission to save the Earth.

To initiate its Maximum Drive, the Double Xtreme Rider Kick, the Xtreme Memory must be closed and then re-opened.

When Philip dissolves after his final battle as Double, the Xtreme Memory, which holds the data of his mind and body, does as well. It is later reformed along with Philip a year after Wakana's sacrifice and the defeat of the Utopia Dopant.

Memory Gadgets
The Memory Gadgets (メモリガジェット) are items powered by artificial Gaia Memories called Pseudo Memories (擬似メモリ) that allow them to switch between their Gadget Mode (ガジェットモード) and their Live Mode (ライブ). The Gadgets can in turn be attached to Double's weapons to provide a boost. The Cyclone, Luna, and Heat Memories can also be inserted into a Memory Gadget, activating a Maximum Drive.
 * The Stag Phone (スタッグフォン) is a cellular phone that switches between Cell Phone Mode (携帯モード) and Stag Mode (スタッグモード) with the use of the Stag Memory (スタッグメモリ). When in Cell Phone Mode, it allows Double to summon and control the HardBoilder and the RevolGarry. The Stag Phone also has a Maximum Drive for the Heat Memory, engulfing it in flames. When attached to the Trigger Magnum, it allows Double to perform the Trigger Stag Burst (トリガースタッグバースト) Maximum Drive, crushing the Dopant between two pincer-like energy projections. When attached to the Metal Shaft, it allows Double to perform the Metal Stag Break (メタルスタッグブレイク) Maximum Drive, crushing the Dopant between two pincer-like energy projections emitted from the Metal Shaft. There are two Stag Phones, one for both Shotaro and Philip.
 * The Spider Shock (スパイダーショック) is a wrist watch that switches between Wrist Watch Mode (腕時計モード) and Spider Mode (スパイダーモード) with the use of the Spider Memory (スパイダーメモリ). It has a grappling hook in Wrist Watch Mode. It can also shoot out trackers which can be tracked in Wrist Watch Mode. When attached to the Trigger Magnum, it allows Double to fire out a net that can capture Dopants. When attached to the Metal Shaft, it allows Double to fire a webbed string to restrain opponents.
 * The Bat Shot (バットショット) is a digital camera that switches between Digicam Mode (デジカメモード) and Bat Mode (バットモード) with the use of the Bat Memory (バットメモリ). A live video feed can be linked to the Stag Phone while in Bat Mode. Its flash can disorient others, and when attached to the Metal Shaft (a combination that Shotaro dubs the Sonic Shaft (ソニックシャフト)), it can emit sonic waves strong enough to shatter solid objects. The Bat Shot also has a Maximum Drive for the Luna Memory, allowing its flashes to reveal and stun any hidden targets in its vicinity. When attached to the Trigger Magnum, it allows Double to perform the Trigger Bat Shooting (トリガーバットシューティング) Maximum Drive, locking onto the target through the Bat Shot and then firing a concentrated blast from the Trigger Magnum.
 * The Frog Pod (フロッグポッド) is a speaker that switches between Speaker Mode (スピーカーモード) and Frog Mode (フロッグモード) with the use of the Frog Memory (フロッグメモリ), which is similar to a MP3 Player that acts as a sound recorder. When the recording is played back, the Frog Pod can modulate the sound to be anyone's voice. Its primary uses are for audio recording and analysis. The Frog Giji Memory and manual for building the Frog Pod are sent to Philip in a black envelope, by a person he believes to be Shroud, the woman who provides Kamen Rider Accel with his transformation items and arsenal.
 * The Denden Sensor (デンデンセンサー) is a pair of night vision goggles that switches between Goggle Mode (ゴーグルモード) (known as "Night Scope Mode" (ナイトスコープモード) on the toybox) and Denden Mode (デンデンモード) with the use of the Denden Memory (デンデンメモリ). Its primary ability is to detect changes in the light spectrum and alert its user to possibly cloaked targets. Its Goggle Mode also serves this purpose, used to detect the presence of the invisible Lily Shirogane in its first appearance. It is also used as a surveillance device, being able to store 8 terabytes of information in its Giji Memory. The Denden Sensor is the second Memory Gadget Philip is seen constructing from a set of instructions sent to him by Shroud.

HardBoilder
The HardBoilder (ハードボイルダー), designated the "MB1000RV", is Double's personal Honda CBR1000RR motorcycle. Like Double, the HardBoilder is black and green and is also able to change forms by swapping out the back half of the motorcycle after docking with the RevolGarry.

HardTurbuler
The first of HardBoilder's forms is the black and red HardTurbuler (ハードタービュラー), which is a hovercraft-like vehicle. The HardTurbuler is armed with Scramble Cutter (スクランブルカッター) guns. The HardTurbuler is often used by Double when he is in HeatMetal form. The HardTurbuler is armed with Scramble Cutter guns. It also can combine with Kamen Rider Accel, forming the AccelTurbuler.

HardSplasher
The second of HardBoilder's forms is the black and gold HardSplasher (ハードスプラッシャー), a jetski-like vehicle. The HardSplasher is armed with a torpedo launcher.

Start Dash Mode
The HardBoilder can also be put into Start Dash Mode (スタートダッシュモード) to increase its speed. The Start Dash Mode components can be detached after deployment to slow down any chasing adversaries.

HardGunner
The HardGunner (ハードガンナー) is the combination of the front unit of the HardBoilder and Kamen Rider Accel's robotic tank the Gunner A. This combination is faster than the HardBoilder and also arms it with the Gaia Cannon.

RevolGarry
The Rotation-Interchange Base RevolGarry (回転換装ベースリボルギャリー) is a truck/garage that holds the HardBoilder and holds a revolving wheel that has the components to change the HardBoilder to the HardTurbuler and HardSplasher.

HardMammother
The HardMammother (ハードマンモシャー) was Double's temporarily owned giant mammoth-like mecha, piloting it when the front unit of the HardTurbuler docks into it. The HardMammother also had a Maximum Drive attack that is activated when the Heat Memory is inserted into the Maximum Slot. It only appears in Kamen Rider × Kamen Rider Double & Decade: Movie War 2010 as the Mammoth Mecha (マンモスメカ) under the control of Super Shocker, then Dummy Dopant's control of it, before Double takes control of it. It is destroyed along with the Super Crisis Fortress after Double sends it flying towards the castle in a kamikaze attack.

Portrayal
Philip and Shotaro Hidari are portrayed by Masaki Suda (菅田 将暉) and Renn Kiriyama (桐山 漣) respectively. At present, their final reprisement of their roles on-screen is in Movie War Mega Max (December 2011). However Renn Kiriyama reprised his role of Shotaro Hidari in Kamen Rider Taisen, but Masaki Suda does not return to reprise his role as Philip in the film.
 * In Super Hero Taisen (April 2012), Kamen Rider Double was voiced by Kenichi Suzumura (鈴村 健一), who voices Ryutaros of Kamen Rider Den-O.

Kamen Rider Double's main suit actor was Seiji Takaiwa (高岩 成二), who has been the suit actor for the majority of leading Heisei Kamen Riders (except Kuuga and Hibiki). He was also the suit actor for Shotaro as Kamen Rider Joker.
 * Secondary suit actors were Makoto Itō (伊藤 慎), Ryo Yokota (横田 遼), and Jun Watanabe (渡辺 淳).

Rider No.
As the leading Rider protagonist of Kamen Rider W, Kamen Rider Double is labeled Kamen Rider #26 (仮面ライダー26号) and Heisei Rider #11 (平成ライダー11号).

In popular culture

 * Episode 295-A of Sgt. Frog titled "Keroro, The Two of Us are One Kerororm" features the members of the Keroro Platoon finding an artifact that allows two of them to combine into a single Keroro, each with new powers. The episode title is based on Double's catchphrase and the resultant transformation resembles that of Kamen Rider Double (the characters appear to be split down the middle, with one side being, for example, Keroro and the other Tamama).
 * In episode 6 of ', ', is seen using a credit card with the letters "CJX" on a green, silver, and black field. This is a dual reference to CycloneJokerXtreme and the real-world Visa company.
 * The anime series, Haiyore! Nyarko-san references Double (both the character and the series) the most often out of its many nods to the Kamen Rider franchise.  In particular, Shotaro's catchphrase "Now, count up your crimes!" is said several times in both the 2012 and 2013 TV series, most often by Nyarko herself.  Other noteworthy references include Nyarko telling her love interest Mahiro "When you find your ultimate partner, it creates a miracle!" (quoting the theme song W-B-X ~W-Boiled Xtreme~) while performing Double's signature finger-point, or an infamous gag in the second season where she and a talking vacuum cleaner end up shouting "Cyclone, Joker!" repeatedly until an annoyed Mahiro puts a stop to it.
 * In the video game Sonic Colors, Sonic's final attack in the game, "Final Color Blaster", visually resembles CycloneJokerXtreme's Prism FinalIllusion. Even more, the narrator who shouts out the Wisps' power types in the Japanese version is the same narrator from Kamen Rider Double, who in turn is the same voice as the Gaia Memories, with the attack's original name being "Final Prism Blaster"
