Rider Cards

This article is about a set of transformational implements in Kamen Rider Decade.

9 Heisei Kamen Ride Card Sealed — The 9 sealed Heisei KamenRide Cards from the start of Tsukasa's journey

Like the Heisei Riders in Kamen Rider Ryuki and Kamen Rider Blade, Decade has card-based weaponry and powers: the Rider Cards (ライダーカード, Raidā Kādo). However, due to a seal placed on them all, Tsukasa travels across the world to undo the seals and regain the abilities the cards endow. These cards match up with Bandai and Carddas's arcade card game, Kamen Rider Battle: Ganbaride.

Like Decade, Diend possesses his own set of Rider Cards.

KamenRide Cards

The KamenRide Cards (カメンライドカード, Kamenraido Kādo) supposedly possess all the powers of the Heisei Kamen Riders it represents, along with Shōwa Kamen Riders as seen in Super Hero Taisen. Because they were sealed, Tsukasa must touch the heart of a world's Kamen Rider in resolving an issue threatening that world. Though he regained his abilities from his journey, the KamenRide Cards went black while fighting Dark Kiva, but were regained later on. It seems the cards are more than just items that supposedly hold the power of the Riders as they sealed themselves until Tsukasa did something which helped the respective A.R Rider as well as learned a lesson from them, implying the Rider Cards hold some degree of sentience. It should also be noted that the cards may not unseal themselves until someone other than Tsukasa holds said cards as shown when the Skull card automatically unsealed itself after being given to Shotaro.

Decade (ディケイド, Dikeido): Initial card; transforms Tsukasa into Kamen Rider Decade. Tsukasa must use this card first before assuming any other transformations.
Kuuga (クウガ, Kūga): Regained when Tsukasa gains Yusuke's trust. ^{[Transcendence]} Decade uses the card to assume Kuuga's Mighty Form.
Kiva (キバ, Kiba): Regained when Tsukasa acknowledges Wataru as the Fangires' King. ^{[The Biting King's Qualifications]} Decade uses the card to assume Kiva's Kiva Form.
Ryuki (リュウキ, Ryūki): Regained when Tsukasa and Shinji worked together to defeat Kamen Rider Abyss, Kamata. ^{[Super Trick of the Real Criminal]} Decade uses this card to assume Ryuki's Ryuki Form. Decade can also travel through mirrors like the original Ryuki and can summon the Drag Saber without the need of an AttackRide Card.
Blade (ブレイド, Bureido): Regained when Tsukasa shows Kazuma that even followers are important as leaders. ^{[Blade Blade]} Decade uses the card to assume the form of Blade's Ace Form.
Faiz (ファイズ, Faizu): Transforms Decade into Faiz, initially sealed after being used once. ^{[Rider War]} Regained when Tsukasa teaches Takumi that protecting those dear to him matters regardless of who he is. ^{[555 Faces, 1 Treasure]} Sometimes, Decade can summon the Faiz Edge without using AttackRide: Auto Vajin. ^{[Amazon, Friend]}
Agito (アギト, Agito): Regained when Tsukasa teaches Shouichi (and Yusuke) that running away from problems mostly isn`t the best solution. ^{[Awakening: Tornado of Souls]} Decade uses this card to assume Agito's Ground Form.
Den-O (デンオウ, Den'ō): Regained when Tsukasa refers to Momotaros by his real name after calling him kind-hearted and restoring his sense of self. ^{[Here Comes Super Momotaros!]} Decade uses this card to assume the form of Den-O's Sword Form.
Kabuto (カブト, Kabuto): Transforms Decade into Kabuto's Rider Form, used once before its power is sealed.^{[Rider War]} Regained when Tsukasa taught Mayu the true meaning about her Grandmother's saying of looks being deceiving while praising Souji's family bonds. ^{[The Grandma Way of Taste]} During Super Hero Taisen event, Tsukasa is shown to be able to summon the Kabuto Kunai Gun while using the Kabuto card. He is also able to use Clock Up without using the AttackRide: Clock Up card, first shown when battling the Go-Busters. ^{[Kamen Rider × Super Sentai: Super Hero Taisen]}
Hibiki (ヒビキ, Hibiki): Transforms Decade into Hibiki, used once before its power is sealed. ^{[Rider War (episode)]} Its silhouette turned black after Hibiki's metamorphosis into Gyūki. ^{[Idle Hibiki]} Regained after Asumu becomes Hibiki and Tsukasa learns the true meaning of the Ongekidō. ^{[Ending Journey]}
Decade Complete (ディケイドコンプリート, Dikeido Konpurīto): A Final KamenRide Card (ファイナルカメンライドカード, Fainaru Kamen Raido Kādo), manifesting after Tsukasa regains his ability to become Decade. By inserting the card into the K-Touch, it transforms Decade into Complete Form.
Black (ブラック, Burakku): A card containing the power of Kamen Rider Black. Diend borrows it to summon Kotaro from the World of Black while in the World of Black RX, as he claims that Decade cannot use the card. ^{[Black × Black RX]} But in theory, this card allows Decade to transform into Kamen Rider Black. He may have later found a way to use it as of Super Hero Taisen.
In Kamen Rider × Kamen Rider W & Decade: Movie War 2010, Decade acquires Kamen Ride Cards for all of the Kamen Riders he defeats, including Skyrider, Super-1, and J. Decade kept these cards after all the Riders were restored.
Skull : In theory it would allow Decade to transform into Skull and summon the A.R Sokichi. Acquired at some point before Movie War 2010 but was sealed until when Tsukasa gave it to Shotaro. When unsealed, this card allowed Shotaro and the others to meet the A.R Sokichi which gave Shotaro closure. It is currently unknown what happened to the Skull card although it is assumable that Shotaro now wields it.
1 (イチゴウ, Ichigō): Transforms Decade into Kamen Rider 1. Unlike other Kamen Rides, this form is a full transformation as the Decadriver was concealed in the form of Kamen Rider 1's belt, the Typhoon. First used in Super Hero Taisen.
Diend (ディエンド, Diendo): Tsukasa had to use this one while in Complete Form in order to perform Dimensional Shoot along with Diend. While originally works as a regular KamenRide card, when used in Decade's Decadriver, it acts as a Final AttackRide card instead. ^{[Destroyer of Worlds]} In the novel, which is a reimagining of the TV Series, Kaito dies and hands this card to Tsukasa, who uses it to transform into a cyan version of Decade in order to battle Narutaki's monster form. ^{[Kamen Rider Decade: The World of Tsukasa Kadoya ~The Garden Inside the Lens~]}

A Gackt KamenRide Card featured in the "Journey through the Decade" and the "Stay the Ride Alive" music videos.

Unlike Decade who transforms into another Kamen Rider, Diend uses his KamenRide cards to summon other Kamen Riders. Diend is not limited to just the nine previous primary Kamen Riders, but has access to any Kamen Rider who has appeared in the Heisei period. The cards of the Extra Riders, including his own, differ from Decade's main nine cards using a white background as opposed to a black one. Eventually, Diend is able to summon Riders from the Showa period as well. Diend has summoned, at most, three different Kamen Riders at once. Diend may have more cards that were not shown.

Diend (ディエンド, Diendo): This standard card transforms Daiki into Kamen Rider Diend. Narutaki presents Daiki with a Diend Kamen Ride Card that will make Diend stronger for the sole purpose of destroying Decade. Unlike the original card, it has a yellow background instead of a white one.

KaijinRide Cards

KaijinRide Cards (カイジンライドカード, Kaijinraido Kādo) allow Chinomanako Diend to summon Kaijin from previous Kamen Rider series. Given that Chinomanako had this set, it is possible that Kaito also had these in his possession.

Eagle Undead: Summon the Eagle Undead. Used once in the World of Shinkenger to fight Decade, Kuuga, and the Shinkengers.

These two cards were released as a bonus for preordering the Complete Selection Modification Decadriver alongside the KamenRide: Diend card and its corresponding Rider Card set, but using them will result in an error sound.

FormRide Cards

FormRide Cards (フォームライドカード, Fōmuraido Kādo) allow Decade to assume any of the forms the Heisei Riders have. Accessing these forms also grants Decade the use of any weapon exclusive to that form, such as the Storm Halber of Agito Storm or the Bassha Magnum of Kiva Basshaa. When using Kuuga's FormRide Cards, Decade gains Kuuga's ability to turn normal items or weapons into their respective weaponry.

Generally, Decade changes forms within one Rider's forms. However, Decade does not have to be a particular Rider to transform into one of that Rider's alternate forms.

Kuuga Dragon (クウガドラゴン, Kūga Doragon): Decade assumes Kuuga's Dragon Form.
Kuuga Titan (クウガタイタン, Kūga Taitan): Decade assumes Kuuga's Titan Form.

Den-O Ax (デンオウアックス, Den'ō Akkusu): Decade assumes Den-O's Ax Form.
Kabuto Masked (カブトマスクド, Kabuto Masukudo): Decade transforms into Kamen Rider Kabuto Masked Form. This card is not used in the series, but in the S.I.C Hero Saga side story, Masked Rider Decade: World of Stronger where Decade uses this card to protect himself from Delza Army General Steel's steel shaft. Unlike the other FormRide Cards, this card transforms Decade into the default form of the Rider instead of a mid-upgraded form.
Den-O Rod (デンオウロッド, Den'ō Roddo): Decade transforms into Kamen Rider Den-O Rod Form. This card does not appear in the television series, but is featured in Hobby Japans Detail of Heroes book on Decade.
Den-O Gun (デンオウガン, Den'ō Gan): Decade transforms into Kamen Rider Den-O Gun Form. This card does not appear in the television series, but is featured in Hobby Japans Detail of Heroes book on Decade.

(ボクニツラレテミル？, Boku ni tsuraretemiru?, "Won't you let me reel you in?"): These two cards were briefly shown following Decade's use of the "Ore Sanjou!" and "Kotaewa Kiite Nai" cards. They were not used in the context of the TV series, but are assumed to have similar effects as the other two cards (i.e. As Den-O, Nakerude! transforms Decade into Ax Form and says his signature phrase while cracking his neck, while Bokuni Tsurarete Miru? transforms Decade into Rod Form and says his phrase while trying to "reel his enemies in").
Tsuppari (ツッパリ, Tsuppari, "Thrust"): As Den-O Ax Form, Decade launches a series of palm strikes.

Final FormRide Cards

Final FormRide Cards (ファイナルフォームライドカード, Fainaru Fōmuraido Kādo) gives Decade the power to bestow new forms upon other Riders by reaching into their back, telling them beforehand "It might tickle a bit". Only while the cards stay in effect, which is during the time Tsukasa is transformed into Decade, the transformed Heisei Rider can alternate between his new form and his original Rider form.

Diend also has his array of Final FormRide Cards. Whereas Decade activates the Heisei Riders' Final Forms by reaching his hands into their back, Diend activates them by shooting the Rider in the back, commenting beforehand "This will only hurt for a moment."

Kuuga Gouram (クウガゴウラム, Kūga Gōramu): Transforms Kuuga into a creature similar to Gouram, giving him the ability to fly.
- In Kamen Rider × Kamen Rider Double & Decade: Movie War 2010, Kuuga gains a new, stronger Final FormRide form called the Ultimate Kuuga Gouram (アルティメットクウガゴウラム, Arutimetto Kūga Gōramu), which he assumed on his own while in Ultimate Form. Decade later gained the ability to have Yusuke assume this form in battle against the Super Crisis Fortress.
- In the novel, Decade uses it on Godai, turning into an alternate Kuuga Gouram based on a rhinoceros beetle; normally this form would be based on a stag beetle, which is also the basis for Kuuga's general design.

This complete form is identical in appearance to the regular, except he is in J's Jumbo size, and does not wear the K-Touch but the Decadriver on his belt buckle.
All Rider (オールライダー, Ōru Raidā): Transforms all nine Heisei Kamen Riders into their Final FormRide forms. When it is used in Movie War 2010, only five of the Riders turn into their Final FormRide forms (Ultimate Kuuga Gouram, Ryuki Dragreder, Agito Tornador, Zecter Kabuto, Hibiki Akanetaka), while three others used their vehicles (The Castle Doran, Jet Sliger and the DenLiner) and the last uses an alternate form (Blade Jack Form).

Unlike the other Final FormRide forms, Double CycloneCyclone and Double JokerJoker do not require their corresponding Final AttackRide card to execute their finishing attack.

Final AttackRide Cards

The Final AttackRide Cards (ファイナルアタックライドカード, Fainaru Atakkuraido Kādo) are Decade and Diend's most powerful attacks, used for finishing off enemies.

The Final AttackRide Cards, if used in conjunction with the Final FormRides, can allow Decade to perform an attack with that Rider's FinalForm (which usually resemble that Rider's own signature attack in some way). If the Final AttackRide is used in conjunction with KamenRide Cards, they allow Decade to perform the signature attack of the Rider he is transformed into. If the Final AttackRide is used when Decade is in Complete Form, he can perform that Rider's signature move (in their ultimate form) alongside the summoned Rider using the Ride Booker to improvise if the attack uses a weapon.

Decade: Decade performs the Dimension Kick (ディメンションキック, Dimenshon Kikku), Decade's Rider Kick. With the Ride Booker in Sword Mode, Decade can execute a highly charged slash called the Dimension Slash (ディメンションスラッシュ, Dimenshon Surasshu). While in Gun Mode, Decade can execute a highly charged shot called the Dimension Blast (ディメンションブラスト, Dimenshon Burasuto). All attacks involve the Decadriver generating large golden Final AttackRide cards, which Decade leaps/runs/shoots through, the final card having an image of Decade's attack before he bursts through it. These hologram cards can also stun the enemy before the attack connects and can line up to track the enemy. In the Ganbaride game, Decade has another final attack, Decade Vanish where he captures the enemy in energy barcode, scanning the target before finishing him off.
- When used by Decade Complete Form, the Dimension Kick becomes the Enhanced Dimension Kick (強化ディメンションキック, Kyōka Dimenshon Kikku).
- Alongside Double CycloneCyclone and Double JokerJoker, Decade executes a triple Rider Kick called the Triple Extreme (トリプルエクストリーム, Toripuru Ekusutorīmu).
- In All Riders vs. Dai-Shocker, a variation of this card is the Final KamenAttackFormRide Card (ファイナルカメンアタックフォームライドカード, Fainarukamen'atakkufōmuraido Kādo) which is used while Decade Complete Form Jumbo Formation is active. Decade performs the Final Dimension Kick (ファイナルディメンションキック, Fainaru Dimenshon Kikku), a variation of the Dimension Kick, transforming the Shōwa and Heisei Riders into KamenRide cards for Decade to travel through as opposed to Final AttackRide cards before hitting the target.
- In Kamen Rider: Climax Heroes, Decade has another final attack, Decade Unlimited (, Decade Unlimited), Decade Complete Form's Rider Kick, in which instead of Final AttackRide card holograms, Decade locks the opponent in a dimension that depicts the nine original worlds and then the ten Heisei Rider symbols appear in the same fashion as the Final AttackRide cards as Decade hits the target with the Rider Kick.
Kuuga: While in Gouram form, Kuuga rushes toward Decade with the target stuck in his pincers while Decade performs the Mighty Kick-like Decade Assault (ディケイドアサルト, Dikeido Asaruto) flying kick towards the target.
Kiva: With the Kiva Arrow, Decade performs the Decade Fang (ディケイドファング, Dikeido Fangu) which fires the arrow, unfolding to hit the target in similarly to Kiva's Darkness Moon Break kick.
- In All Riders vs. Dai-Shocker, when Tsukasa "loans" the Kiva Arrow to Momotaros, the attack is called Momo Fang (モモファング, Momo Fangu), labeled by Momotaros as "Our Finishing Attack, Final Attack Version" (俺たちの必殺技・ファイナルアタックバージョン, Oretachi no Hissatsu Waza: Fainaru Atakku Bājon).
Ryuki: With Ryuki Dragreder flying behind to boost his attack's power, Decade performs the Decade Dragoon (ディケイドドラグーン, Dikeido Doragūn) which is similar to Ryuki's Final Vent, the Dragon Rider Kick.
Blade: With the Blade Blade, Decade performs the Decade Edge (ディケイドエッジ, Dikeido Ejji) where the Blade Blade charges with electricity then is slashed down to make a huge electric shockwave similar to Blade's Lightning Slash. The same card can be used by Decade while as Blade, executing Blade's Lightning Blast kick.
Faiz: With the Faiz Blaster, Decade shoots an energy drill at the enemy before performing the Decade Photon (ディケイドフォトン, Dikeido Foton), a powerful laser blast with some recoil, which is similar to Faiz's Crimson Smash kick.
Agito: On the Agito Tornador, Decade executes a slashing attack called the Decade Tornado (ディケイドトルネード, Dikeido Torunēdo) which is similar to Agito's Saber Brake Slash. The same card can be used by Decade while as Agito, executing Agito's Rider Kick.
Den-O: Momotaros executes the Decade Liner (ディケイドライナー, Dikeido Rainā) similar to Den-O's Extreme Slash, labeled by Momotaros as "My Finisher Attack, Decade Version" (俺の必殺技・ディケイドバージョン, Ore no Hissatsu Waza: Dikeido Bājon).
Kabuto: The Zecter Kabuto charges at the opponent in a devastating mid-air body slam, Decade Meteor (ディケイドメテオ, Dikeido Meteo). With the target left vulnerable in mid-air, Kabuto and Decade execute their respective kick attacks while in Clock Up. The same card can be used by Decade in Kabuto's Rider Form to execute Kabuto's Rider Kick.
Hibiki: With Hibiki Ongekiko, Decade performs the Decade Wave (ディケイドウェイブ, Dikeido Weibu), where Hibiki Akanetaka transforms into the Hibiki Ongekiko and attaches to the target and allows Decade to perform his version of an Ongeki Da finisher using Hibiki's Ongekibou Rekka.
Amazon (アマゾン, Amazon): The GaGa Armlet is transferred to Amazon, and allows Amazon to perform the Super Dai Setsudan (スーパー大切断, Sūpā Dai Setsudan, Super Great Slice) attack.
Diend: Using the Diend Final AttackRide card allows Decade to execute an Dimension Shoot-style attack alongside Diend.
11 Riders: With 11 Kamen Riders (Kuuga - W) execute their respective 11 Rider Kicks. Did not appear in the movie or series but included in Ganbaride games (both arcade and DS).

These cards are seen used by Diend's most powerful attacks, used for finishing off enemies in the series and movies.

Diend: Diend performs the Dimension Shoot (ディメンションシュート, Dimenshon Shūto). Nine rings of cards showing the previous nine Heisei Riders appear before the Diendriver. Diend then sucks in any Riders summoned by his KamenRide cards before firing a shot from the Diendriver at the target, coming out as a green and black beam.
- When used by Diend Complete Form, the Dimension Shoot becomes the Enhanced Dimension Shoot (強化ディメンションシュート, Kyōka Dimenshon Shūto) which shoots out a gold-colored beam of energy.
Kiva: With the Kiva Arrow, Diend performs the Diend Fang (ディエンドファング, Diendo Fangu) which fires the arrow, unfolding to hit the target in similarly to Kiva's Darkness Moon Break Rider Kick. Unlike Decade, who holds the arrow vertically, Diend holds it like a crossbow.
Blade: With the Blade Blade, Diend performs the Diend Edge (ディエンドエッジ, Diendo Ejji) where the Blade Blade charges with electricity then Diend slashes the enemy, making a huge electric shockwave similar to Blade's Lightning Slash

Showa KamenRide Cards

Decade performs the Final Dimension Kick (ファイナルディメンションキック, Fainaru Dimenshon Kikku), a variation of the Dimension Kick, transforming the Shōwa and Heisei Riders into KamenRide cards for Decade to travel through as opposed to Final AttackRide cards before hitting the target.

Wizard

The Rider Cards, along with the other Rider Powers, were stolen from Decade by Amadum in the world within the Magic Stone, who explained that they were already his due to the Riders' powers being from the same source as evil. However, the power was soon returned thanks to the appearance of Kamen Rider Gaim, with the return of the Rider Cards immediately transforming Decade into Complete Form. ^{[Neverending Story]}

Notes

These are the third Collectible Devices to be cards, following Advent Cards and Rouze Cards.
Strangely, the KamenRide: Shin card does not actually depict Shin himself; it instead depicts Onizuka Rider.
Interestingly, the Complete Selection Modification Decadriver announces Den-O's Super Climax Form as "Chou Climax" rather than "Super Climax" as in Kamen Rider × Kamen Rider W & Decade: Movie War 2010.
Through hacking, someone managed to find sounds for Riders from Double to Drive in the CSM Decadriver, possibly hinting at Rider Card releases for said Riders.
The art on the AttackRide: Advent card is the exact same as that on Ryuki's Advent Card of the same name.

Influences to & from Super Sentai

The "KamenRides" preceded the Gokai Changes of Kaizoku Sentai Gokaiger. Like the KamenRides, the Gokaigers could transform into any past sentai.
- However, Super Sentai came first with heroes transforming into past heroes in AkaRed, who appeared in GoGo Sentai Boukenger vs. Super Sentai (2006). AkaRed had the ability to transform into past Sentai Reds, he also appeared in Gokaiger.
- In the same vein, the Final FormRides preceded the Inordinate Power of Hikonin Sentai Akibaranger as like the Final FormRides, the Akibarangers could transform some past Red Rangers into weapons based on their motif. The transformation, however, isn't nowhere near as graphic as in Kamen Rider Decade.
  - A nod to the Final FormRides previously occurred in the finale of Gokaiger, where Gokai Green, having Gokai Changed into Zubaan from GoGo Sentai Boukenger, changed from its humanoid form to Sacred Sword Mode, expressing discomfort both during and after the transformation, while the original Zubaan in Boukenger was not a human but the Golden Sword Precious itself, being able to assume a humanoid fighting form when the seal on the sword was turned.

Rider Cards and Ranger Keys — Narutaki compares the Rider Cards with the Ranger Keys of *Kaizoku Sentai Gokaiger*.

The Rider Cards of Decade and the Ranger Keys of Kaizoku Sentai Gokaiger were noted by Narutaki as one of the similarities between Decade and Gokaiger in the Super Hero Taihen net movie The Grown-ups’ Narumi Detective Agency Ep. 1: Is Gokaiger a Ripoff of Decade?.
The design of the Rider Cards are similar to PreCards from the 2014 anime series Happiness Charge Pretty Cure! (coincidentally also a 10th anniversary season), both have a barcode on a side and a magenta border. Both are also used to access forms and powers of the main protagonists's abilities.
