"I'm just a passing-through Kamen Rider. Remember that!"
―Tsukasa's answer when asked who he is[src]

Tsukasa Kadoya (門矢 士 Kadoya Tsukasa?) is Kamen Rider Decade (仮面ライダーディケイド Kamen Raidā Dikeido?, Lit. Masked Rider Decade), who is the main protagonist and eponymous character of the Kamen Rider Series Kamen Rider Decade.

History

Becoming Decade

When Tsukasa is confronted by Natsumi Hikari 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 kaijin 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 of Worm, Orphnoch and Makamou. Confused by both his actions and the cards's 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.

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.

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.

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. Black × Black RX

World of Decade

The Hikari Family Studio ends up in a world which is discovered to be Tsukasa's home world, the World of Decade, 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 and it is revealed that he was the Great Leader of Dai-Shocker. But the victory is short lived as Nobuhiko is revealed to be Shadow Moon and Sayo as Priestess Bishium takes control of Yusuke 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 Yusuke. 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 amends with Sayo and leaves with the Hikari Studio. Kamen Rider Decade: All Riders vs. Dai-Shocker

World of Amazon

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 Yusuke 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. Amazon, Friend The Strong, Naked, Strong Guy

World of the Rider War

Complete Form Final Attack Ride DiEnd

Decade Complete Form uses the Attack Ride of Diend.

The Rider War World is Decade's undoing as he witnesses both Kamen Riders Blade and Kiva lead Rider armies against each other. Tsukasa and Yusuke 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 he 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. Rider War: Prologue Destroyer of Worlds

Movie War 2010

"The answer is simple. I am the destroyer of all. I have accepted that."
―His answer when Natsumi confronted him[src]

In Decade: Final Chapter, despite unwillingly as the Destroyer of Worlds, Tsukasa accepts his role 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 Kaito 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.

Let's Go Kamen Riders

A mishap caused by the Greeed Ankh unintentionally altered the timeline which enabled Shocker to utilize the Core Medal to create the Shocker Greeed which defeated the Double Riders and seemingly erased the legacy of the Kamen Riders from history. In 2011, after Kamen Rider New Den-O's attempt to repair the damage, he along with Kamen Rider OOO and M-Ankh awaited execution. However, it was revealed the Double Riders had their brainwashing removed by a Shocker scientist.

The Double Riders joined with New Den-O and OOO to fight Shocker's forces, but were eventually defeated. When the order was given to kill everyone, V3 suddenly appeared, asserting that there were more than four riders. V3 was soon followed by all the other revived riders that came after him, as even though Rider history was changed, the people's memories haven't changed. Decade appeared after the three 90s riders and the first eight Heisei riders, defeating the Paradoxa Undead, Tiger Orphnoch and Shadow Moon in quick succession.

After the riders were united, they faced off against Shocker's Great Leader. Later, when joined by a force of extra riders, Decade got into his Machine Decader, and alongside all the other riders in their vehicles performed the "All Rider Break", ramming into the Rock Great Leader and defeating it once and for all. OOO, Den-O, All Riders: Let's Go Kamen Riders

Kamen Rider × Super Sentai: Super Hero Taisen

"Destroy all Super Sentai... or die trying!"
―his words as the leader of Dai-Shocker[src]

Tsukasa appeared in a movie alongside the Gokaigers in a Super Sentai meets Kamen Rider event, Kamen Rider × Super Sentai: Super Hero Taisen.

Doktor G resurrected and gathered all defeated Rider villains, recreating Dai-Shocker. He told Tsukasa that the Riders and monsters needed to destroy the Super Sentai to ensure the survival of the Riders, and, answering that, Tsukasa took control of the new Dai-Shocker, becoming its Great Leader again to battle the Super Sentai and also the Dai-Zangyack, a new union of Super Sentai villains led by the Gokaiger's Captain Marvelous. As the Great Leader of Dai-Shocker, Tsukasa apparently destroyed many Super Sentai teams, apparently leaving only GokaiRed and GokaiGreen alive, while Decade himself was seemingly the last remaining Rider. After he was wounded in his battle against Gokai Red, Doktor G used the opportunity to overthrow him and take control of the organization. The story about Riders needing to destroy Sentai to survive was a lie, and Doktor G was actually allied with Dai-Zangyack and using both Gokai Red and Decade to destroy the other heroes and afterwards kill the nominal leaders of the two organizations.


However, Tsukasa and Marvelous already realized that trap from the beginning before the war starts. The destruction of the Super Sentai actually just an act and the truth was, all the Super Sentai and Riders were just sent into a rift between dimensions. Tsukasa turned against Dai-Shocker and Dai-Zangyack, supported by all other Riders and Super Sentai. Alongside the Gokaigers, he killed General Shadow. In the end, he faced Doktor G, the man behind the new Dai-Shocker, and defeated him with the help of the Super Sentai team Goseiger, and Kamen Riders Ryuki and Blade. However, after being defeated, Doktor G was revealed to be Decade's old enemy, Narutaki, who escaped afterwards, and his real identity was left a mystery.

Decade and other space heroes

Space Sheriff Gavan Type G, alongside Kamen Rider Beast and Yellow Buster invaded the fortress of the Space Crime Syndicate Madou on Earth. However, inside, they're overrun by the forces of Space Shocker, which had allied itself with Madou. Gavan was separated from the others and trapped by Shocker's forces, when Kamen Rider Kamen Rider Fourze arrived, answering the call for help of Gokai Silver, who asked for reinforcements to help in the attack. Fourze brought with him more allies, including Meteor, Super-1, the Super Sentai teams Choushinsei Flashman, Tokusou Sentai Dekaranger and Decade himself to confront Space Shocker. Decade briefly fights against Tortoise Undead and afterwards pierces through a Pteranodon Yummy.

Afterwards, Decade presumably stays fighting against the other reinforcements brought by Space Ikadevil, while Fourze is thrown out of the area. Space Ikadevil himself is finished by the Super Sentai team Gokaiger, while Gavan and Meteor leave to fight against Space Shocker's and Madou's leaders. After the battle is over, Decade appears on top of a nearby cliff alongside the other heroes who appeared to help to say goodbye to Gavan and the others.

World of Monsters

Decade was summoned along with OOO by the alternate version of Haruto, taking the children to the shop. Before taking the children away, he thinks that he has arrived in the World of Wizard, but Haruto tells him that he is mistaken.The Kamen Rider Rings He is summoned again by Amadum to retrive back the Fourze Rider Ring from Haruto. He then teamed up with Haruto along with the Heisei Riders to fight Amadum and his monsters. However, Amadum was too powerful for the Riders as he takes their items from them, until Gaim arrives. Gaim easily beats Amadum up as the Riders regaining their items to transform into their final forms. After Amadum is defeated, and the Rider Rings gone, Tsukasa leaves to continue his journey, stating that Haruto and him will meet again. Neverending Story

Kamen Rider Taisen

Tsukasa returns in Kamen Rider Taisen. He is informed by Shotaro that both Heisei and Showa Riders are starting a war. However, both are confronted and attacked by Black and Black RX , who saw the Heisei Riders as unforgivable nuisances. Shotaro asked Tsukasa to find the rookie Heisei Rider of Zawame, Kouta Kazuraba who was confronted by Takeshi Hongo, who had Mitsuzane killed and turned into a Lockseed, at Drupers. Once finding Kouta at Drupers, he helps Kouta with leading the Heisei side. He, Haruto, Kouta, Takumi, and Keisuke soon realized that almost all Riders have been brainwashed by Ren Aoi/Kamen Rider Fifteen into fighting one another, which is also how Hongo became so ruthless, and eventually calls a truce to stop the war and restore the Riders' alliance together. 

At the climax, Decade is one of the surviving Riders in the battle between Heisei and Showa. He is attacked by Kamen Rider #2's Rider Punch, with the two Riders defeating each other at the same time and transforming into their Lockseeds. Gaim is soon left as the last Rider standing before Ambassador Darkness of the Badan Empire reveals himself to be Ryo Murasame (Kamen Rider ZX). Together, they restore the other Riders and all 30 Kamen Riders defeat the Badan Empire. Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai

―Decade encourages G.[src]

At some point during his travels across the worlds, Decade came through a dimensional wall to a world which was home to Goro (Kamen Rider G), who was having a hard time fighting a Phylloxera Worm. Decade told G, who recognised Decade, that he was the only one who could save his world. Decade was soon followed by the Nine Heisei Riders through the dimensional wall behind him. Kuuga and Ryuki gave G their words of encouragement, then all ten Riders called out to him. With a boost in confidence, G got up and destroyed the Phylloxera Worm with his Swirling Rider Kick as the ten Heisei Riders vanished. Kamen Rider G

Novel

Kamen Rider Decade: The World of Tsukasa Kadoya ~The Garden Inside the Lens~

In the novel which is the reimagination of the TV Series, Tsukasa is generally the same personality wise. But his world is different from the world in Kamen Rider Decade: All Riders vs. Dai-Shocker movie. He has no sister and his parents live overseas. In the novel he’s described as a young NEET tired of his mundane life, the only thing he finds interesting is photography. He ends up stumbling upon an abandoned photo studio, inside he finds an old camera standing on a tripod. Tsukasa picks it up and peeks through the viewfinder. Through the viewfinder, Tsukasa sees a completely different world. Instead of a flimsy Eijiro Hikari that knocks down a backdrop, the group uses the camera to travel between worlds. In fact, Eijiro doesn’t even exist in the novel. The photo studio isn’t some ordinary photo studio that was just abandoned. It actually manifests itself in front of people that are tired of their own world and want to find a new world. Natsumi, Kaito and Narutaki, all found the photo studio in their own respective home worlds. In addition, Dai-Shocker, the evil organization itself never existed.

Tsukasa met Natsumi in the first unnamed world he traveled to. A world where monsters are attacking humans. Natsumi sees this and calls Tsukasa by the name ‘Decade’ and gives him the Decadriver, telling him he must transform. A confused Tsukasa goes along with it and becomes Decade for the first time. They travel to another world together and meet Daiki Kaito. He acts hostile towards Tsukasa, but still decides to follow the two on their travels.

With 6 A.R. Worlds discovered leaving Den-O, Kuuga and Kabuto's World unexplored, the trio arrived at The World of Den-O with Tsukasa’s clothes change into a doctor’s uniform as they arrive. Tsukasa meets Ryotaro, but his Imagin friends are missing. Tsukasa agrees to help him find them. The Den-O characters feel very off-character as their characteristics are different. Momotaros comes off as rather polite compared to his jerkish and self-centered TV counterpart, and actually refers to people by their real names instead of snarky nicknames. The Final Form Ride remains the same, as Tsukasa turns Den-O into Momotaros.

Arriving at Kuuga's World, Tsukasa is dressed as a painter and meets Yusuke Godai while having difficulties of remembering the name Decade and usually goes with “Kamen Rider Dickens.”

Despite being Kuuga’s world, Tsukasa doesn’t interact much with Godai.

Instead he meets a mysterious unnamed girl, with her sentences spoken in broken grammar. This girl approaches different men saying “Do you want me?” The girl is referred as Yuri after Tsukasa sees her holding a lily flower, yuri in Japanese. She asks the question to Tsukasa, but Natsumi doesn’t like it and uses her Laughing Pressure Point technique on him. Yuri takes a liking to Tsukasa and connects with him. Tsukasa says they are the same type of people, and relate to each other. But he reveals that he never really paid attention to her and never cared about her. From the start, Natsumi oddly suspects that Yuri is a Gurongi. This is never truly touched upon until the where Yuri reveals the truth and challenge the Riders into a fight. Her Gurongi group is not mentioned, but she’s described as a Moth, meaning she's of the Ba class of Gurongi. She causes people to explode by sticking moth scales from her wings on people. Decade and Kuuga defeat her together. Decade's Final Form Ride for this Kuuga is also different: while it retains the ability to transform Kuuga into the Kuuga Gouram, the Gouram is described as a rhinoceros beetle, despite it traditionally being a stag beetle, which is also the same insect Kuuga is based on. Godai gives Tsukasa a thumbs up as they leave.

They shortly move onto the world of Kabuto, where they meet Souji Tendou, still as arrogant and confident as ever, and considers himself as the strongest Rider ever. The group enters Bistro La Salle where Hiyori Kusakabe works. Hiyori sees Kaito and Tsukasa, dressed as ZECTroopers, claiming that the two of them ate without paying. Tendou hears this and is enraged. The three of them fight and Tendou actually beats them with only a pair of chopsticks. However, it turns out to be a pair of Worms that ate without paying. Tsukasa and Kaito are eventually captured by ZECT, only to have Tendou save them. Tsukasa thanks him and says that he never thanks people. Tsukasa starts respecting Tendou. For some inexplicable reason, Tendou has the Clock Up Attack Ride Rider Card and gives it to Tsukasa after he realizes that he is Kamen Rider Decade. Tsukasa uses the Clock Up card as Kuuga, meaning the Attack Ride cards aren’t restricted to their respective Riders in the novel. In the end, the Worms that impersonate both Tsukasa and Kaito have been defeated. As the fight is over the trio goes back to Tsukasa’s world.

Between all the traveling, a vampire has been attacking in Tsukasa’s world, leaving behind drained corpses. The group investigates and they find out that Narutaki is the vampire. Just like the group, Narutaki originally had his own homeworld, but abandoned it to find a new one. However, he’s been traveling for so long that his mind has been deteriorating and can barely remember who he really is. He was originally a human, but somehow in his journeys, he had lost his humanity. The Kamen Riders have a very pure energy that Narutaki seeks to consume: the Rider Cards. Thus, he sends Kaito to steal them for him. Kaito reveals his betrayal towards the team and gives Narutaki Tsukasa's 9 Heisei Rider Cards and Narutaki reveals his real form: a red-hued demon.

Kaito suddenly has a change of heart, and sacrifices himself to save Tsukasa. All hope seems to be lost; Tsukasa even uses a Diend card with the DecaDriver, which turns him into a cyan-hued version of Decade. However all seems hopeless, as he was badly overpowered by Narutaki and reverts into human form again. Natsumi, who had just realized that she has special powers all along, creates a special card with the 9 previous Heisei Riders on it. Tsukasa uses it, which summons the previous 9 Heisei Riders to do their finishers onto Narutaki. They then turn into cards and attached themselves onto Decade, turning him into Final Kamen Ride: Tsukasa, which can be described as Complete Form without a K-Touch. Tsukasa then finishes off Narutaki via a Rider Kick. In his dying words, Narutaki wanted to destroy all worlds and then create his own ideal world. He dies looking at Natsumi, knowing that she had the power to do what he wished for.

With the crisis over, Tsukasa returns to his world and Natsumi decides to go with him and live in his world. When they return, Tsukasa finds an article where it says Tsukasa's world's version of Natsumi died after committing suicide due to worldly troubles.

A few decades later, an unchanged young Kaito revives and reappears in front of an elderly Tsukasa. Kaito tells him it’s time to visit Natsumi’s world. There they are greeted by a young Natsumi, and Tsukasa finds himself as a young man again. Kamen Rider Decade: The World of Tsukasa Kadoya ~The Garden Inside the Lens~

―Decade telling Wizard to quickly destroy the Mnemozyne.[src]

Decade (Battride War).

Kamen Rider Decade 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.

In the game, Decade is the only character to picked 3 from 9 main pre-Decade's Heisei Kamen Ride Forms (mostly their main forms), in which Decade able to access his normal sword attacks with the other Kamen Rider's ground special attacks. While performing a finishing moves (Final Attack Ride) in some Kamen Ride Forms, it will revert back to Decade. His ultimate form, Complete Form can access an ultimate attacks anytime depends on the some Kamen Ride to be used on. Like Blade, Beast and Wizard Infinity Style, Decade can perform a normal aerial slash twice.

Decade's special attacks are:

  • Attack Ride:
    • Decade: Blast (rapid tap), Slash (three times)
    • Kabuto: Clock Up (Special 1: followed with dash slashing. Limited until Clock Over when no attacks (mainly normal to special 1 chains) or/and recently deactivated while being hit, using special 1 spam attacks or special 2 (Clock Up like special radial attack))

Personality

Tsukasa 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 Gurongi 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-through 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.

Rider Powers

He mostly appeared as Kamen Rider Decade. Only in Episode 14 of Kamen Rider Decade, he briefly transformed into Kamen Rider Den-O Sword Form after possessed by Momotaros.

Kamen Rider Decade's ending theme is entitled "Ride the Wind".

  • Kicking Power: 16t
  • Maximum Jump Height: 50m
  • Maximum Running Speed: 100m/4

Complete Form (コンプリートフォーム Konpurīto Fōmu?) 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 Kamen Ride Card on his helmet, embedded in the Decade Crown, and the others' Kamen Ride 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, Movie War 2010, and Kamen Rider Wizard Episode 53), this version of Complete Form is called Strongest Complete Form (最強コンプリートフォーム Saikyō Konpurīto Fōmu?). In the novel, Natsumi creates a Kamen Ride card which Tsukasa as Kamen Rider Decade Cyan Version uses it which summons all 9 Heisei Riders to perform their finisher attacks at Narutaki before they could turn themselves into Rider Cards and attached to Decade into becoming Final Kamen Ride Tsukasa which is a cyan version of Decade Complete Form only without the K-Touch.

  • Maximum Jump Height: 30 meters
  • Maximum Running Speed: 100 meters per 5 seconds

For most of the first act of Kamen Rider × Kamen Rider Double & Decade: Movie War 2010, Decade assumes his dark rider form called Kamen 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 Decade's false 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.

Diend Super Machine Legend!!, when he entered Toei's Rider Machine Planning Room (Color Adjustment Room). There he saw his Machine Decader bike also colored cyan, refered to as the "Machine Diender", it was promptly taken by a green-colored Diend.

  • Maximum running speed: 100m/5.2s

Tsukasa was also once possessed by Momotaros, who then used the Den-O belt to transform into Sword Form to fight the Mole Imagin.

When possessing Tsukasa (or anyone else) or by himself, Momotaros can assume Den-O's Sword Form through the Terminal Buckle, the first and most used form in the series. When in Sword Form he uses the DenGasher as a standard sword-style weapon. This form is the most balanced among Den-O's forms, probably due to Momotaros' prominence among the other Imagin. He occasionally forms different finishers for defeating enemies, despite parts 2, 3, and 5 being similar to each other. He also uses a Special Version in I'm Born which resembles the aforementioned parts, the only difference is that Full Charge is used twice. There is also a Final Version used against the Death Imagin which uses energy from the other Taros, Sieg, and Kamen Rider Zeronos. In the Cho Den-O series Sword Form also has a triple Roundhouse Rider Kick that Momotaros dubs his "Super Finishing Attack." The DenKamen Mask resembles two halves of a peach, which is based on the story of Momotaro.

Behind the scenes

Portrayal

Tsukasa Kadoya is portrayed by Masahiro Inoue (井上 正大 Inoue Masahiro?), who reprised his role in Kamen Rider × Super Sentai: Super Hero Taisen, the special episodes of Kamen Rider Wizard, and Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai.

While disguised as Kamen Rider 1 in Kamen Rider × Super Sentai: Super Hero Taisen, he is voiced by Tetsu Inada (稲田 徹 Inada Tetsu?). In Kamen Rider × Super Sentai × Space Sheriff: Super Hero Taisen Z, Kamen Rider Decade's voice was provided by Katsuhiro Suzuki (鈴木 勝大 Suzuki Katsuhiro?), who plays Hiromu Sakurada/Red Buster in Tokumei Sentai Go-BustersIcon-crosswiki.

As Kamen Rider Decade, his suit actor was Seiji Takaiwa (高岩 成二 Takaiwa Seiji?), who has been the suit actor for the majority of leading Kamen Riders in the Heisei era (except Kuuga and Hibiki). In Super Hero Taisen and Kamen Rider Taisen, his suit actor was Jun Watanabe (渡辺 淳 Watanabe Jun?).

Etymology

Tsukasa's surname translates to Gate (?) Arrow (?) which reference the Dimensional walls he is associated with, while his given name means Gentleman (?).

Rider No.

As the leading Rider protagonist of Kamen Rider Decade, Tsukasa Kadoya (Kamen Rider Decade) is labeled Kamen Rider #25 (仮面ライダー25号 Kamen Raidā Nijūgogō?) and Heisei Rider #10 (平成ライダー10号 Heisei Raidā Jūgō?). Quiz! Decade Countdown!!

In Popular Culture

Haiyore! Nyarko-san episode 3 contains an extended reference to Decade in the rooftop lunch scene. Cuuko teases Nyarko with a cake from the legendary space bakery DK-Do, owned by a man named D. Endo. The cake is said to be a limited 10th anniversary special production, and is modeled on the Decadriver; additionally, when Nyarko explains about the bakery to Mahiro, its name appears in black and magenta stripes, while D. Endo's is represented with black and cyan. Later on, Nyarko transforms her pet Shantak-Bird into a motorcycle, with her remarking "This may tickle a bit. Heck, it'll only hurt for a moment;" in the light novels, this Final Form Ride-style forced transformation is explicitly stated to be one of Nyarko's unique special powers.

  • Additionally, Nyarko's favorite television show is Iron Striver, a tokusatsu show made on Earth that serves as an obvious homage to the Kamen Rider franchise.  A brief segment of the show seen in the OVA episode "How to Defeat a Kind Enemy" shows it to mostly be based off of Decade, with the main character physically resembling Tsukasa and using with a card-reading belt that forms the word "StriveRide" to transform. Said segment also features direct quotes from Decade, with Striver telling the villains "Bring it on! I'll destroy everything!"

Notes

  • Decade's name is taken from the English word decade 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.
  • Even though he can copy all previous riders, he lacks the power of Riders from the Showa Era, any extra Rider, and any Kamen Rider after him.
    • However, he eventually transforms into Kamen Rider 1 in Super Hero Taisen, which shows that he can change into any of the 15 Showa Riders.
  • As said in the Net Movies, Decade is the Heisei Era equivelant of Kamen Rider ZX.
  • The name "Gekijōtai" (激情態?) is a pun on the word for "theater" (劇場 gekijō?), which literally translates as "Fury Form". The May 2010 issue of Hyper Hobby magazine, as well as S.H. Figuarts toyline, officially translates this name as "Violent Emotion", a literal translation of gekijō (激情?) and omitting any translation for tai (?).
  • Ever since Decade, Rider Belts are referred to as "Drivers" until Mage's Belt. Although Kamen Rider Gaim continue this tradition with the Sengoku Driver and Genesis Driver.
  • Tsukasa is the only Rider to have no definitive type, but in the end he always becomes the hero, not an anti-hero through the series until movie war (Super Hero Taisen doesn't count due to it being just his plan to defeat his enemy).
  • When Decade transforms into another rider, usually his belt does not change. But it is revealed that the belt can change appearance in Super Hero Taisen via holographic imaging.
  • Decade is currently the last primary rider to not have multi-forms (this is due to the other form changes considered as just copying and not his actual ability).
  • Tsukasa is the last primary Rider to make his debut in the first episode of his own series, as the following Riders, except for Gaim, make their debut as a cameo appearance in the Summer Movie of their predecessor.
  • He is one of three Kamen Riders to borrow a Super Sentai's power. The other two are Ryuki and Blade.
    • Coincidentally, he has done it twice (the first from Shinkenger).
  • Tsukasa is one of 2 leader figures that are human and not some manner of kaijin, the other being The Real Man and Woman from Kamen Rider Hibiki. Hiroshi Tennoji, Ryubee Sonozaki, Doctor Maki, and Mitsuaki Gamou are also human leader figures but they later became an Undead, a Dopant, a Greeed, and a Zodiarts respectively. Out of all of them Tsukasa is the only one to resign from his leader position.

    • I don't think so, the only reason why Gaim had one was because his suit wasn't a part of the Lockseed used. For Decade, it's just there and ser...
    • Oh ok, thanks for the clarification.
  • Mystic or Tech (II)?

    • It is probably both tech and mystic. Plus, some of the riders in the final form are mystic and others are tech based, so having both would make sense.
