Kamen Rider Decade

Kamen Rider Decade (仮面ライダーディケイド Kamen Raidā Dikeido^?, Lit. Masked Rider Decade) is the primary protagonist andeponymous character of the first 2009 Kamen Rider Series Kamen Rider Decade. Decade's name is taken from the English worddecade as Decade is the 10th of the Heisei run of the Kamen Rider Series, evidenced by the Roman numeral X (ten) on his chest. His logo features the numbers 453 and 145 below the bar code. These digits correlate to the English letters A, C, D, and E to form the word "DECADE". He is also the first Rider to have a series that crosses over with a Super Sentai TV show, in this case Samurai Sentai Shinkenger, though the honor of being the first Rider to appear in a crossover belongs to his rival Kamen Rider Diend.

Tsukasa Kadoya Edit

Tsukasa Kadoya is a hypocritical and self-righteous young man who does not know much about his past. He has a strong desire to "catch the world" using his photos, but they never develop well. He sees this as a sign that he is not of this world, unaware of it being a prelude of it being supplanted by the worlds of the other nine Kamen Riders. However as Decade, he is seen as an agent of destruction, usually being called "the devil", a rumor spread by Narutaki, who believes Tsukasa does not belong in any world.

It is also revealed that those who appear in his badly developed photographs die or foreshadow events. As Tsukasa travels between dimensions, his clothing changes to suit the Rider's World, including some accouterments similar in color to his camera and Decade. He also exhibits some prior knowledge or a talent necessary to his quest in the Rider's Worlds he enters. Some examples are his knowledge of the Grongi language in Kuuga's World and his enrollment as a student in Faiz's World. He has also mentioned before that he is capable of doing anything except for taking photos.

Before a climatic battle begins, Tsukasa answers a major villain's demand for his identity by saying that he is "Just a passing Kamen Rider, remember that!" (通り過がりの仮面ライダーだ、覚えておけ！Tōrisugari no Kamen Raidā da, oboeteoke!).

Tsukasa uses a "Decade Pink" Blackbird, fly 135 Twin Lens Reflex Camera.

Fictional character biography Edit

When Tsukasa is confronted by Natsumi over the photos he has taken, the two get separated by a dimensional barrier that sends Natsumi into an unstable pocket dimension where she flees for her life from various monsters before finding the Decadriver from her dreams. While looking for her, Tsukasa encounters Wataru Kurenai, who calls him "Decade". Wataru tells him today is the day his world will end, and that he is needed to protect it.

After finding Natsumi, Tsukasa uses the Kamen Ride Cards to assume the forms of Kabuto, Faiz and Hibiki to deal with groups ofWorm, Orphnoch, and Makamou. Confused by both his actions and the cards' powers' fading, Tsukasa takes Natsumi and returns to their world as it is being destroyed by the various monsters. When time suddenly freezes, Wataru appears, revealing the status of the worlds and assigning Tsukasa the task of traveling into the other worlds to stop the dimensional chaos inflicted on his own world by meeting the Riders of each of the other dimensions.

Starting in the World of Kuuga as a police officer, Tsukasa meets the world's Rider, Yuusuke Onodera who battles the Grongi and learns that that someone is disseminating rumors across the Worlds about him as a destroyer of worlds. After reconciling with Yuusuke, the two stop the Grongi N-Gamio-Zeda from taking over the world.

At the World of Kiva as a violinist, Tsukasa encounters the young boy Wataru, helping the boy realize his role as King of the Fangire Race to maintain the peaceful coexistence of the human and Fangire races while defeating the Beetle Fangire: Wataru's father and the former King.

Then at the World of Ryuki, Tsukasa defends the framed Natsumi in a murder case and solves it with the aid ofShinji Tatsumi. The true villain, Kamata is revealed to have been an Undead all along and is taken by Narutaki to the World of Blade after his defeat.

Assuming the role of chief waiter under the BOARD Corporation while being promoted repeatedly, Tsukasa works with Kazuma Kendate to uncover the conspiracy between Kamata and BOARD's CEO, Kamen Rider Chalice, to take over the world through the Joker card which the latter used on himself. After he and Blade work together to defeat the Undead, Tsukasa takes his leave as Kazuma thanks him.

Decade, Destroyer Of Worlds

In the World of Faiz as a student of the Smart Brain High School, Tsukasa crosses paths with a man he saw at the World of Blade who knows him, Daiki Kaito. Though Kaito warns him to stay out of his affairs, Tsukasa finds Faiz after confronting the Lucky Clover group, learning that he is Takumi Ogami as he attempts to keep his Faiz Belt away from Kaito. Tsukasa later resolves the tension between Takumi and Yuri Tomoda over Takumi's identity, giving Takumi the will to continue protecting the school.

Arriving in the World of Agito as a postman, Tsukasa reads a discard letter meant for Shouichi Ashikawa, making it his goal to protect Ashikawa from the Unknown for the sake of Toko Yashiro, the writer of the letter. With Yuusuke's help, Tsukasa succeeds in having Shouichi achieve the necessary state of mind needed to complete his evolution to Agito before reuniting him with Yashiro.

Upon arriving in the World of Den-O, Tsukasa becomes Den-O under the possession of an Imagin, before forcing him into Yuusuke's body. Here, he learns that some unknown force is changing the past as he is fought by the other Taros possessing Natsumi's body who believe Decade to be the source. Learning the Imagin possessing Yuusuke is named Momotaros, Tsukasa finds him and helps him regain physical form as they defeat the AlligatorImagin.

Believing their adventures with Den-O to be over, only to learn that identity of the true culprits for Den-O World's time distortions, they prepare to travel to the World of Kabuto until the Swan Imagin Sieg comes into the Hikari Studio with a manuscript showing a battle at Onigashima. With Sieg's help, Tsukasa and company travel with the DenLiner crew back in time to fight the Oni Rider Brothers before returning to the present time in the World of Kabuto.

In the role of a ZECTrooper, after witnessing TheBee and Gattack's fight against a Worm, Tsukasa brings Arata to the Photo Studio where he finds a Salis Worm that had mimicked him. After the impostor is exposed, the Worm is killed by Kabuto when it attempted to kill a girl named Mayu whose brother was believed to have been killed by Kabuto. Although it seemed that TheBee's user, Sou Otogiri, is her brother, Tsukasa felt something was not right. After learning that Mayu herself is a Worm, both his meeting with Grandma and learning the full nature of the Kabuto Capture Plan allow him to get the full story. Arriving to Mayu's aid, Tsukasa helps Kabuto, Mayu's real brother Souji, in defeating Otogiri in his true identity, the Phylloxera Worm.

After bringing Mayu back to her Grandma and giving Daiki a vial of pepper as a "treasure", Tsukasa begins the journey into the final world, the World of Hibiki. Here, Tsukasa meets a encounters an Oni in training named Asumu. From there, believed Great Master of Ongekidō style , Tsukasa meets the three masters of the Ongekidō Styles before being pulled into a ploy by Daiki to rob the two Oni masters Ibuki and Zanki, worsening when they are attacked by the Makamou Gyuki until Akira and Todoroki drive the beast off. Supporting their intent to end the rivalry among their schools, Tsukasa convinces Ibuki and Zanki to pass the torch. Tsukasa later offers his aid to Asumu after he became the new Hibiki thanks to Daiki, whom he still acknowledged as a thief and nothing more.

Complete Form

Added by Asgardite203

With the journey over, Tsukasa and the others of the Hikari Studio return to what appears to be Natsumi's world to find it back to normal as if it was not plagued by the monsters. Despite being in a perfect world that he has earned, according to Otoya Kurenai, it is revealed that it is only a parallel version of their own world where the monsters have taken over and killed all but a few humans.

After being tested by Otoya, Tsukasa gains the K-Touch after turning down Otoya's offer to live in a world of lies, using Decade's Complete Form to take out the Dark Riders. Knowing that their journey is not really over, the Hikari Studio group heads to the next world, Kaito's homeworld. Arriving in the World of Diend, he finds himself in the role of a salaryman selling products to the society until he encounters Shin and Haruka, Kamen Riders Lance and Larc, fighting a Darkroach.

He learns that Daiki is the lackey of the evil Fourteen who brainwashed the inhabitants of the World of Diend to believe that Kamen Riders are evil, having unknowingly given up his brother to Fourteen. He and Daiki team up to defeat Fourteen to free all those who have been brainwashed, leaving only Daiki's brother Junichi, Kamen Rider Glaive, who was not brainwashed but accepting of Fourteen's peaceful world. He teaches the two brothers that they have to protect each other, no matter what, before heading off to the next world, one which he has no knowledge of at all.

In the guise of a kuroko with a strange card in hand, Tsukasa learns that his lack of knowledge is due to the world not having any Kamen Riders as he witnesses the Shinkengers drive off the Nanashi. Curious about them, Tsukasa uses his guise to learn more about them and their world before fighting the Ayakashi Chinomanako who has stolen the Diendriver from Daiki. He realizes that the monster is the reason why he is in this world as Chinomanako escapes and becomes the world's first Kamen Rider. He attempts to fight the Chinomanako but is stopped by Narutaki saying that his actions will only bring doom to the world. After being given the advice to do the right thing by Hikoma Kusakabe, Decade later helps the Shinkengers with the card revealing to be the Rekka Daizantou which he uses to destroy Chinomanako alongside ShinkenRed using the Blade Blade.

He leaves this world and enters Kamen Rider BLACK RX's receiving another card being mistaken as Joe the Haze when he changes clothes and is attacked by Schwarian and his Chap minions while meeting Kotaro Minami himself. Decade then finds out that Dai-Shocker is in this world planning to conquer it. Decade teams with RX to help fend off the assault on this world. Eventually the Security Chief of Dai-Shocker, Apollo Geist drains Natsumi's life through his Perfector ending up in a hospital and Tsukasa desperate to revive her. Decade learns of Apollo Geist and the Perfector from Kaitoh and goes off to find him, but Kaitoh also has his agenda of retrieving the device. Decade, with assistance from RX, battles Geist but Guy leaves through a dimension wall. Tsukasa follows him in pursuit but ends up in Kamen Rider BLACK's World with no way out.

BLACK attacks Decade after he mistakes him for RX's Kotaro Minami. Decade refuses to fight and Diend appears to stop BLACK with Femme's power. They retreat and Decade continues his search for Guy. As Ryuki he fights him and saves a child, gaining BLACK's trust in the process and teaming up with him. They come across Geist and the newly recruited Schwarian, although Guy escapes through dimensional wall BLACK uses "King Stone Flash" to help Tsukasa get back to RX's world through the wall. Decade re-encounters the RX Kotaro and finds Guy. His card is revealed to be a Kamen Rider BLACK card but Diend uses it instead and the two Kotaros transform and fight Geist and Schwarian. Decade is able to get the Perfector but Diend steals it and runs away. Decade then destroys Schwarian with Agito's powers while the two BLACKs force Geist into retreating.

At the hospital Kaitoh hands over the Perfector to saying that there are other treasures that he has already taken from this world and there are always more to get from other worlds. Kaitoh takes his leave saying to Tsukasa to save his friend. Decade uses the Perfector to drain part of his life and implant it into Natsumi reviving her. Before leaving Tsukasa tells Kotaro that Joe the Haze is helping his counterpart. But Kotaro is not saddened by it, knowing that Joe will be with him in spirit. The gang returns to the photo shop where the next world is waiting which is Amazon's World.

When Tsukasa enters Amazon's world he immediately assumes the mantle of a baseball player and receives yet another card. He immediately sees that Dai-Shocker has taken over this world and is attacked by some of the monsters from different worlds. Amazon appears suddenly and helps Decade fight them but before a finishing blow could be done the people intervened convinced by Dai-Shocker that riders are destroyers forcing them to retreat.

They run into Kaitoh again where he explains his plan to steal Amazon's GiGi armlet's counterpart, the GaGa armlet which is unfortunately owned by the Ten-Faced Demon Llumu Qhimil, Dai-Shocker's designated ruler of the World of Amazon. Llumu sends out Masahiko Okamura to reveal the Rider's location by faking an attack by the Dai-Shocker foot soldiers and gaining their trust. Apollo Geist appears once more fighting Decade demanding his Perfector but Decade destroys it instead. The fight goes on until Masahiko steals the GiGi armlet after Dai-Shocker turns on him.

With Dai-Shocker now aware of where the Riders might go the gang goes to a nurse's office at Shocker School where Tsukasa finds a picture of Masahiko and his family before his father passed away. They are then driven off by Masahiko's older sister and the Dai-Shocker foot soldiers. They quickly come up with a plan to retrieve the GiGi armlet after Masahiko turned it over to them and was put up to be the first in the Humanity-to-Monster Project. He is saved by Tsukasa and Yuusuke in disguise as foot soldiers and explains what happened. As they go out and retrieve the GiGi Armlet Amazon joins the fight against Llumu Qhimil, while Diend successfully obtains the GaGa Armlet during the battle. However this is short-lived as Tsukasa uses the armlet for himself through the use of his new card until giving to Amazon who delivers the final blow to Llumu with Super Big Slice. Amazon is then adopted into Masahiko's family and the gang returns to the photo shop to find Diend sitting there and he proposes that he go with them.

They accept and head into the next world which will be the site where all the riders are supposed to be "The Rider War World". It is the same place that Natsumi saw when she had her dream about the war. In an unspecified time before the World of the Rider War the Hikari Family Studio ends up in the World of Dai-Shocker where Tsukasa meets his sister Sayo Kadoya and starts a tournament to find the strongest Rider to save the world after hearing he must be the one to do so by Nobuhiko Tsukikage, Sayo's butler.

Tsukasa wins but the victory is short lived as Nobuhiko is revealed to be Shadow Moon and Sayo as Priestess Bishium takes control of Yuusuke through the Stone of Earth to attack Tsukasa as part of revenge for abandoning her, despite not knowing the truth. Tsukasa is left alone as even his friends abandoned him. He is later encountered by Joji Yuki a former scientist for Dai-Shocker that wanted payback by Tsukasa for doing said punishment to him. Later he realizes that Tsukasa is no longer affiliated with Dai-Shocker and fights Dai-Shocker as Riderman as Tsukasa moves away.

Tsukasa joins in the fight against Dai-Shocker starting with the fight against General Jark. He and all of the Kamen Riders from the Showa and Heisei Era Fight Dai-Shocker destroying Ambassador Hell and Doctor Shinigami as Garagaranda and Ikadevil respectively. Later Decade fights the Bishium-controlled Kuuga Rising Ultimate but realizing he's talking with his sister, he convinces Sayo that Nobuhiko is only using her to further his goals.

Sayo knowing the error of her ways destroys the Stone of Earth, freeing Yuusuke. With the stone destroyed Shadow Moon fights Decade and Kuuga Rising Ultimate overpowering them until Double shows up and flings him to Dai-Shocker's castle. Tsukasa along with all of the other riders destroy Shadow Moon with the All Rider Kick. After Shadow Moon and the castle is destroyed, King Dark appears. Diend summons J and uses the Decade Final Form Ride to turn Decade into the Jumbo Decadriver and turns J into Decade Complete Jumbo Formation destroying King Dark. Tsukasa later makes ammendments with Sayo and leaves with the Hikari Studio.

The War World is Decade's undoing as he witnesses both Kamen Riders Blade and Kiva lead Rider armies against each other. Tsukasa and Yuusuke try to keep both sides from killing each other and finding out the Fangire Queen, Yuki marries Guy and becomes Super Apollo Geist. With this new enemy Tsukasa destroys Yuki with Ryuki Survive's abilities and the rest of the Fangire and Undead armies with help from Kazuma Kendate and Wataru. Unfortunately Super Apollo Geist uses his powers to make the worlds merge with Kazuma and Garren disappearing and Geist kidnaps Natsumi. He is then confronted by Kazuma Kenzaki, the original Kamen Rider Blade.

Decade finally finds out why the worlds are merging and it is because of Decade himself. Kenzaki tranforms and assumes King Form, Decade is quickly defeated. Decade returns to the photo studio injured and finds out that every picture he took in the other worlds are completely blank because they are nearly gone. Decade heads out to follow Kivala and is confronted by Hibiki and Kiva who fight him. The two Riders were talked into helping Kenzaki save their own worlds. Kuuga saves Decade while he deals with Geist.

Decade catches up to Geist who has brought back all the different monsters decade fought in the different worlds. Decade is quickly overwhelmed by too many enemies but with Kuuga, Hibiki, Kiva, and Diend he manages to drive the creatures back. Decade immediately fights Geist who has become very powerful with his super mode. Diend hands Decade his Kamen Ride Card and with the power of Diend two bursts annihilates Geist. Decade is exhausted and collapses with Kiva and Hibiki finally fading away because their worlds no longer exist.

Decade is taken to the place where it all started the place where he met the original Wataru. Wataru explains that Tsukasa messed up his job and says that he and the others will fight him as he transforms into Kiva. Decade is again transported to the War world where the original Riders appear and Kuuga becoming Ultimate Form to fight Decade due to Kivala. Diend aims his gun directly at Decade's head at point blank range. With that the Rider War begins.

In Decade: Final Chapter, Tsukasa accepts his role as the Destroyer of Worlds and turns into Violent Emotion Decade destroying many Riders and turning them into cards. He is assisted by Yuriko Misaki who reminds Tsukasa of Sayo and can transform into Electro-Wave Human Tackle. He is confronted by Natsumi who has become Kamen Rider Kivala to stop his rampage. Before Tsukasa disappears after he voluntarily lets her destroy him, he gives Natsumi the Kamen Ride Cards and tells her that as long as people remember the Riders they will never disappear.

Natsumi and Kaitoh learn from Wataru Kurenai of Decade's role as the destroyer and connector of worlds, as Tsukasa would destroy the Riders he would connect the other worlds preventing their collapse and does anything he is needed for as a hero or a villain to finish the Rider's story. He himself however has no story and with his task complete Decade was gone forever.

Despite this Natsumi finds a way to revive him through the use of a picture and the A.R. Riders' memories and Tsukasa is resurrected. Tsukasa and the gang along with other Riders fight against Super Shocker receiving more help from Kamen Rider Double who appear to know each other. With Double's Final Form Ride and Final Attack Decade destroys Super Shocker's most powerful and evil kaijin, Ultimate-D.

He is last seen with his friends posing for a picture after the battle while continuing his adventures across the A.R. Worlds.

Kamen Rider Decade Edit

• Height: 192cm

• Weight: 83kg

• Punching Power: 4t

• Kicking Power: 8t

• Maximum Jump Height: 25m

• Maximum Running Speed: 100m/6

Decade can transform into any previous Kamen Rider with access to that respective Rider's powers and weapons. However, during Decade's battle with Dark Kiva in the Nega World, Decade loses his power and ability to transform. One of Tsukasa's particular gestures is dusting his hands, or running a hand along the blade of his sword, while fighting.

Complete Form Edit

• Height: 199cm
• Weight: 102kg
• Punching Power: 12t
• Kicking Power: 16t
• Maximum Jump Height: 50m
• Maximum Running Speed: 100m/4

Complete Form is the true form of Decade that is able to manipulate the power of other Riders' final forms, accessed through the K-Touch once he regains the powers of all of the Heisei Kamen Riders. Referred to as the "King of the Rider Worlds", he wears the Decade Complete KamenRide Card on his helmet, embedded in the Decade Crown, and the others' KamenRide Cards on his chest. When Complete Form features the most powerful forms of the Heisei Kamen Riders on the cards (as seen in the Super Adventure DVD, the series finale, and Movie War 2010), this version of Complete Form is called Strongest Complete Form (最強コンプリートフォーム, Saikyō Complete Form^?).

Final Form Ride: Jumbo DecadriverEdit

In Kamen Rider Decade: All Riders vs. Dai-Shocker, Kamen Rider Diend uses a Final Form Ride card that turns Decade into the Jumbo Decadriver (ジャンボディケイドライバー, Janbo Dikeidoraibā^?), a larger version of the Decadriver which is worn by a Diend Kamen Ride Card-summoned Kamen Rider J to transform into Decade Complete Form Jumbo Formation (ジャンボフォーメーション, Janbo Fōmēshon^?). This complete form is identical in appearance to the regular, except he is J's jumbo size, and does not wear the k-touch but the decadriver on his belt buckle.

Violent Emotion Edit

• Height: 192cm
• Weight: 83kg
• Punching Power: 5t
• Kicking Power: 10t
• Maximum Jump Height: 30m

For most of the first act of Kamen Rider × Kamen Rider Double & Decade: Movie War 2010, Decade assumesKamen Rider Decade 'Violent Emotion' (仮面ライダーディケイド激情態, Kamen Raidā Dikeido Gekijōtai^?). This form is described as Decade's final transformation into the destroyer of worlds, with Decade's body in a lighter shade of magenta, the eyes assuming a more sinister appearance, and the normally yellow Signal Pointer (the light on Decade's helmet) is violet. While this form appears similar to Decade's normal form, it is drastically stronger, both possessing greater combat capability (enough to go toe-to-toe with Kuuga Ultimate Form and destroy countless other riders) and able to use Attack Ride cards such as Clock Up without having to transform into the associated Rider first.

Kamen Ride FormsEdit

Through the Kamen Ride and Form Ride cards Decade can transform into any of the previous primary nine Heisei Era Kamen Riders and their forms, with the exception of their most powerful forms.

Equipment Edit

DecadriverEdit

• Change announcement: KAMENRIDE
• Form Change announcement: FORMRIDE
• Attack announcement: ATTACKRIDE
• Rider Form change announcement: FINAL FORMRIDE
• Final attack announcement: FINAL ATTACKRIDE
• Decade Complete announcement: FINAL KAMENRIDE

Tsukasa transforms into Decade through the use of the Decadriver belt that is based around the Rider Cards. By inserting a card into the Decadriver, Decade can invoke the cards' abilities. In Complete Form, the Decadriver is moved to the right side of his belt where Decade inserts his Final Attack Ride Cards and activates them by touching the Decadriver's window.

Rider Cards Edit

Like the Heisei Riders in Kamen Rider Ryuki and Kamen Rider Blade, Decade has card-based weaponry and powers: the Rider Cards. 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.

Kamen Ride Cards Edit

The Kamen Ride Cards supposedly possess all the powers of the 9 previous Heisei Kamen Riders. 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 go black while fighting Dark Kiva, later they are regained.

• Decade: Initial card; transforms Tsukasa into Kamen Rider Decade. Tsukasa must use this card first before assuming any other transformations.
• Kuuga: Regained when Tsukasa gains Yuusuke's trust. Decade uses the card to assume Kuuga's Mighty Form.
• Kiva: Regained when Tsukasa acknowledges Wataru as the Fangires' King. Decade uses the card to assume Kiva's Kiva Form.
• Ryuki: Regained when Tsukasa and Shinji work together to defeat Kamen Rider Abyss, Kamata. Decade uses the card to assume the form of Ryuki. Decade can also travel through mirrors like the original Ryuki.
• Blade: Regained when Tsukasa shows Kazuma that even followers are important as leaders, Decade uses the card to assume the form of Blade.
• Faiz: Transforms Decade into Faiz, initially sealed after being used once. Regained when Tsukasa teaches Takumi that protecting those dear matters regardless of who he is.
• Agito: Regained when Tsukasa teaches Shouichi (and Yuusuke) that you can't run away from your problems. Decade uses this card to assume the form of Agito's Ground Form.
• Den-O: Regained when Tsukasa refers to Momotaros by his real name after calling him kind-hearted and restoring his sense of self. Decade uses this card to assume the form of Den-O's Sword Form.
• Kabuto: Transforms Decade into Kabuto's Rider Form, used once before its power is sealed. Regained when Tsukasa taught Mayu the true meaning about her Grandmother's saying of looks being deceiving while praising Souji's family bonds.
• Hibiki: Transforms Decade into Hibiki, used once before its power is sealed. Its silhouette turned black after Hibiki's metamorphosis into Gyūki. Regained after Asumu becomes Hibiki and Tsukasa learns the true meaning of the Ongekidō.
• Decade Complete : A Final KamenRide Card, manifesting after Tsukasa regains his ability to become Decade. By inserting the card into the K-Touch, it transforms Decade into Complete Form.
• Black : 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.
• In Kamen Rider × Kamen Rider Double & Decade: Movie War 2010, Decade acquires Kamen Ride Cards for all of the Kamen Riders he defeats, including Skyrider, Super-1, and J. Amongst these cards is also the Kamen Rider Skull card but unlike the others, it is sealed (he later gave it to Kamen Rider Double). Decade kept these cards after all the Riders were restored.

A Gackt KamenRide Card featured in the "Journey through the Decade" music video.

Form Ride CardsEdit

Form Ride Cards allow Decade to assume any of the forms the Heisei Riders have. Accessing these forms grants Decade the use of any weapon exclusive to that form. 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: Decade assumes Kuuga's Dragon Form.
• Kuuga Titan: Decade assumes Kuuga's Titan Form.
• Kuuga Pegasus: Decade assumes Kuuga's Pegasus Form. Tsukasa does not suffer from the same sensory overload that was depicted in the original series.
• Kiva Garulu: Decade assumes Kiva's Garulu Form.
• Kiva Basshaa: Decade assumes Kiva's Basshaa Form.
• Kiva Dogga: Decade assumes Kiva's Dogga Form.
• Agito Flame: Decade assumes Agito's Flame Form.
• Agito Storm: Decade assumes Agito's Storm Form.
• Faiz Axel: Decade assumes Faiz's Axel Form. While in the original series, this form moved at the speed of sound for only 10 seconds, Decade's version allows him to match the Worms and the ZECT Riders' Clock Up system which moves at the speed of light.
• Den-O Ax: Decade assumes Den-O's Ax Form.
• Kabuto Masked: 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 Form Ride Cards, this card transforms Decade into the default form of the Rider instead of a mid-upgraded form.
• Den-O Rod: 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: 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.
• Den-O Wing : Decade transforms into Kamen Rider Den-O Wing Form. This card does not appear in the television series, but is featured in Hobby Japans Detail of Heroes book on Decade.

Attack Ride Cards Edit

The Attack Ride Cards allow Decade to perform any of his own attacks, or a signature attack of whatever Kamen Rider he has transformed into.

• Blast: As Decade, this grants the Ride Booker's Gun Mode rapid fire capabilities.

Decade's fireballs are powerful enough to destroy giant Makamou as well.
• Onibi: As Hibiki, Decade breathes a powerful flamethrower through a mouth that forms from the mask.
• Autovajin: As Faiz, Decade turns the Machine Decader into the Autovajin, Faiz's own motorcycle, which goes into Battle Mode. This also allows Decade to access the Faiz Edge via the Autovajin's right shoulder.
• Strike Vent: As Ryuki, Decade summons the Drag Claw, a dragon-headed gauntlet that can send a burst of flames out of its mouth. Unlike the original Ryuki, it does not need Dragreder's assistance.
• Metal: As Blade, Decade invokes the power of the Seven of Spades Rouse Card, Metal Trilobite, to enhance resilience to physical harm by transmutating his body into organic metal.
• Mach: As Blade, Decade invokes the power of the Nine of Spades Rouse Card, Mach Jaguar, to enhance his speed and agility.

Final Attack Ride CardsEdit

The Final Attack Ride Cards (ファイナルアタックライドカード, Fainaru Atakku Raido Kādo^?) are Decade's most powerful attacks, used for finishing off enemies. The Final Attack Ride Cards, if used in conjunction with the Final Form Rides, can allow Decade to perform an attack with that Rider's Final Form (which usually resemble that Rider's own signature attack in some way). If the Final Attack Ride is used in conjunction with Kamen Ride Cards, they allow Decade to perform the signature attack of the Rider he is transformed into. If the Final Attack Ride 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, Decade's Rider Kick. With the Ride Booker in Sword Mode, Decade can execute a highly charged slash called the Dimension Slash. While in Gun Mode, Decade can execute a highly charged shot called the Dimension Blast. 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 Kamen Attack Form Ride Card (ファイナルカメンアタックフォームライドカード, Fainaru Kamen Atakku Fōmu Raido 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 Kamen Ride cards for Decade to travel through as opposed to Final Attack Ride cards before hitting the target.

• 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 flying kick towards the target.
• Kiva: With the Kiva Arrow, Decade performs the Decade Fang 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 calledMomo 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).

• Den-O: Momotaros executes the Decade Liner similar to Den-O's Extreme Slash, labeled by Momotaros as "My Finisher Attack, Decade Version."
• Kabuto: The Zecter Kabuto charges at the opponent in a devastating mid-air body slam, Decade Meteor. 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, where Hibiki Ongekiko attaches to the target and allows Decade to perform his version of an Ongekida finisher using Hibiki's Ongekibou Rekka.

• 11 Riders: With 11 Riders do the 11 Rider Kicks. Did not appear in the movie.

K-TouchEdit

The Final Kamen Terminal K-Touch is a special touchscreen cell phone. Originally from the World of Negatives in the possession of the Dark Riders, the K-Touch was designed to attach onto the Decadriver replacing the card slot, which is moved to his right hip, allowing Decade to transform into Complete Form. In this form, Decade can still use his Ride Cards by inserting them in the card slot and touching its visor, allowing Decade to summon the powers and weapons of the ultimate form of any of the previous Kamen Riders. When a Rider is summoned, the cards on Complete Form's chest and shoulders change to match the Rider's specific Kamen Ride card and the summoned Rider copies Decade's motions. When activating the K-Touch's functions in Complete Form, any of the Nine Heisei Riders present will be transformed into their most powerful form.

Machine DecaderEdit

Decade Bazooka Edit

The Decade Bazooka is a firearm weapon of Decade's that is only seen in the Kamen Rider Decade: Protect The World of Televi-Kun Super Adventure DVD. To tie in with the DVD, the Decade Bazooka is constructed from cardboard punchouts and glue by Yusuke Onodera, much like prizes given out with issues of the Televi-Kunmagazine. Though it expands from its original toy-like size to the size of a full bazooka when given to Decade, it clearly remains a cardboard prop, though this does not impede its functionality as a weapon.
