―Double's pre-battle catchphrase[src]

Kamen Rider Double (仮面ライダーダブル Kamen Raidā Daburu) 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.

In an alternate timeline where Shocker rules the world after the defeat of the Double Riders by Kamen Rider #3, they were referred to as Shocker Rider Double (ショッカーライダーダブル Shokkā Raidā Daburu). It is under this title that he participates in the Rider Grand Prix. Super Hero Taisen GP: Kamen Rider 3



Double first nine form combinations

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.


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 are 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 as Philip wanted to go home, 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 Philip 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.

―Shotaro and Philip prepare to fight once more[src]

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.

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. Kamen Rider × Kamen Rider Fourze & OOO: Movie War Mega Max

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 ZyurangersIcon-crosswiki and MegarangersIcon-crosswiki. 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.

Double was part of a force of Rider and Sentai reinforcements led by Kamen Rider 1 and AkarengerIcon-crosswiki that came to assist the Riders and Sentai of recent years who were overwhelmed by the revived monster army of the Space Crime Syndicate MadouIcon-crosswiki. 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 Demon King PsychoIcon-crosswiki 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.

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.

Double first appears alongside Fourze, summoned to the world within the Magic Stone through their Rider Rings by the alternate young Haruto, as the prime Haruto watches, to protect him and his Koyomi from the pursuing monsters, namely a trio of Masquerade Dopants and a trio of Dustards, sent by Amadum, the evil wizard who ruled that world. Fighting the henchmen, Double and Fourze assumed HeatMetal and Elek States temporarily, defeating the Masquerade Dopants before taking their battle with the Dustards to the city as Faiz and Kabuto were fighting a trio of Worms. Double and Fourze finished off the Dustards with a Joker Extreme Maximum Drive Rider Kick and Rider Rocket Drill Kick respectively. The Kamen Rider Rings

Double is later summoned with all the other Riders when the 13 Rider Rings are taken by Amadum, the evil wizard who rules the world of monsters, to defeat Wizard, only to find out that they will not obey him just because he possesses their rings, and that they will always fight for freedom and not merely justice. After the Riders destroy his initial guard of monsters, Amadum tries to escape with the boy Haruto, summoning his strongest and largest monsters to deal with the Riders. However, the Riders individually pull out their various tricks to deal with the giant monsters, with Double assuming LunaTrigger temporarily. With his monsters destroyed, Amadum attempts to force the boy to wish to leave this world. The Kamen Riders attempt to stop him but to no avail, having their powers stolen by Amadum's true monstrous form when they try to fight him, with Double having his memories absorbed. However, the young Haruto defies Amadum after hearing the words from Wizard of turning despair into hope, summoning a new Rider to his world. This new Rider, Gaim, gives himself the Kamen Rider name after being told by Wizard that they come to help when people request it. This revelation that the Kamen Riders aren't bounded by evil turns the tables on Amadum as he is beaten back by Gaim, forcing the powers he stole to be returned to the other Riders, transforming them to their ultimate forms, with the return of the Gaia Memories immediately transforming Double into CycloneJokerXtreme. Double then participates in a successive barrage of Rider Kicks from all 15 Riders against Amadum which is finished by Wizard and Gaim. After Amadum is destroyed, Double stands with the other Riders watching over the young Haruto as he wakes up before returning to his world. Neverending Story

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 respective Rider Kick on each other. However, the defeated Riders would return thanks to Gaim as they battle the Badan Empire. (Strangely, Double was in his Cyclone/Joker form rather then his Joker form for some unexplained reason). 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. Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai

Due to the timeline alteration caused by Shocker, Double became one of the brainwashed Riders in that timeline, donning the name of Shocker Rider Double. He later volunteered in a Kamen Rider Grand Prix but he was eliminated by Kamen Rider 3 during the Rider Grand Prix, along with Gaim. Later on, he aided the other Riders to combat Shocker after he, and the other Riders, were released from being brainwashed by the revived Double Riders.

Battride Wars Kamen Rider Double

Double (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

Super Hero GenerationIcon-crosswiki

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[1].


Kamen Riders Cyclone & Joker

Kamen Riders Cyclone and Joker.

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! Saa, omae no tsumi o kazoero!), 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 Hāfu Chenji), 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 Memori Chenji) 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 Makishimamu Doraibu) 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 Memori Bureiku).



  • Double Driver - Transformation belt as Double
  • Gaia Memories - Devices that used in Double's transformation or power-ups in finisher attacks.
    • Fang Memory - Dinosaur-like Gaia Memory that assist Philip whenever he is in distress. Also allows him to become Double as Fang Joker.
    • Xtreme Memory - Bird-themed conjoined Gaia Memories that transforms Double into Xtreme Mode. Philip resides in this Memory during the period of reconstructing his new body.
  • Memory Gadgets - Support robots that empowered by pseudo-Gaia Memories.


  • Maximum Slots - Gaia Memory slot that enables Double to perform Maximum Drive as barehanded.
    • Metal Shaft - Extendable quarter staff in conjunction with any form that uses the Metal Memory.
    • Trigger Magnum - Firearm in conjunction with any form that uses the Trigger Memory.
    • Prism Bicker - A pair of sword and shield that used in CycloneJokerXtreme.

Behind the scenes


Philip and Shotaro Hidari are portrayed by Masaki Suda (菅田 将暉 Suda Masaki) and Renn Kiriyama (桐山 漣 Kiriyama Ren) 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.

Kamen Rider Double's main suit actor was Seiji Takaiwa (高岩 成二 Takaiwa Seiji), 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.

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 Kamen Raidā Nijūrokugō) and Heisei Rider #11 (平成ライダー11号 Heisei Raidā Jūichigō). Quiz! Decade Countdown!!

In popular culture

Kamen Rider W Keroro Platoon

The form are similar to Double is: *KeroTama=Cyclone Joker *KeroGiro=Cyclone Accel? *KeroDoro=Cyclone Trigger *KuruDoro=Luna Trigger

  • 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).
First the Bat credit-card and now this

Komaki's credit card.

  • In episode 6 of Kaizoku Sentai GokaigerIcon-crosswiki, The Most Important ThingIcon-crosswiki, Komaki KasugaiIcon-crosswiki 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 W, who in turn is the same voice as the Gaia Memories, with the attack's original name being "Final Prism Blaster"


  • Double is the first Rider to cameo in a preceding Rider's Summer movie.
  • Double is currently the only Rider that requires two people in order to transform into a Rider.
  • The colors of three of Double's forms are similar to three other Toku heroes:
  • CycloneJoker as Double's basic form is possibly a reference to the original Kamen Rider. Both are green and black in color, both are related to wind and wore scarves (the Cyclone Memory uses the power of wind while Kamen Rider 1's Typhoon belt uses the power of wind to transform), and both colors are white on Double's Cyclone half's scarf and Rider 1's gloves and boots. Furthermore, Kamen Rider 1's motorcycle's name is Cyclone.
    • HeatMetal is a possible reference to Kamen Rider X, as both Double and X have a red and silver color scheme and wield a pole weapon which they use for their respective finishers.
  • CycloneAccelXtreme and CycloneJokerGoldXtreme were never created as physical costumes, instead being digital alterations of the base CycloneJokerXtreme costume. CycloneAccelXtreme appears as a hidden character in Climax Heroes OOO, where he wields the Engine Blade and Prism Bicker (with the Bicker Sword sheathed).
  • As FangJoker, Double is the first Rider with a Dinosaur motif, immediately followed by Kamen Rider OOO Putotyra Combo.
  • According to the Double novel, while the FangMetal and FangTrigger forms could potentially be used, doing so would be disastrous. It's stated that Shotaro's compatibility with the Joker Memory lets him keep Fang's berserker nature in check; since he lacks such compatibility with the Metal and Trigger Memories, FangMetal and FangTrigger would be uncontrollable.
  • Double is the only Neo-Heisei Era Rider to have a Final Form Ride card.
  • Double is currently the most complicated Main Rider when it comes to transforming as both Shotaro and Philip have to cooperate with each other, as well as have some synchronization together, to maintain their transformation.
W Concept

Concept art of the trench coat idea from the Kamen Rider Character Making Report File.

  • According to the producers, Double was originally going to wear a trench-coat in his transformed state, but it was decided not to include it.
  • During the planning stages, Yasuko Koboyashi originally opposed adding a scarf to the costume, as she stated that was too "Showa Rider-y" and modern kids wouldn't like it because to them it would be "unsightly". She eventually allowed it under the condition that the scarf be a different material and silver instead of white.
  • Double is heavily influenced by the tokusatsu hero Barom One. Like Double, it features a right handed "smart" hero and a left handed "strong" hero fusing together into one being to combat the forces of evil. Unlike Double however, One is not separated into two parts.
  • When Double becomes FangJoker, the trademark line's finger point is on the right hand as opposed to the usual left hand, due to Philip being the host rather than Shotaro.
  • Although Shroud stated that Double`s full potential comes from hatred, this may not be true as Shotaro and Philip have shown when they transformed into CycloneJokerGoldXtreme through wind blowing into the Xtreme Memory and hope from the citizens of Futo.
  • Double is the only lead Neo-Heisei Era Rider to not have a special title for his forms.
  • The transformation pose for Double has Shotaro and Philip forming the letter W when their arms were across from their body.
  • A split screen would occur when Shotaro and Philip transform into Double if they are on different location. However if appearing at the same spot, the split screen would not occur.
