- "I'm just a passing-through Kamen Rider. Remember that!"
- ―Tsukasa's answer of 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?) from the series of the same name. He, along with two other Kamen Riders, teams up with The Shinkengers in one episode of Shinkenger and two crossover episodes of Kamen Rider Decade: episodes 24 ("Arrival of the Samurai Sentai" (見参侍戦隊 Kenzan Samurai Sentai?)) and 25 ("Heretic Rider, on Call!" (外道ライダー、参る！ Gedō Raidā, Mairu!?)).
Tsukasa is an arrogant, young man without any memory of his past. As a photographer, his photos never come out right, which is later revealed to be a sign of his world being slowly destroyed by the convergence of the other Kamen Riders' worlds. To save his world, he transforms into Kamen Rider Decade.
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. After which, Tsukasa and his friends leave the Sentai world.
Super Hero Taisen
- "Destroy all Super Sentai... or die trying!"
- ―his words as the leader of Dai-Shocker[src]
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. After the battle, Tsukasa reconciles with Daiki accepting his friendship before the latter takes his leave.
Super Hero Taisen Z
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.
Kamen Rider Taisen
Tsukasa managed to find Kouta in Drupers, telling the young Rider that he somehow knew Shuu before Narutaki appears to them. He warns the Riders about Badan's plan and the situation between the Riders from both eras, having Kouta become curious about it. Tsukasa would plan to gather the Heisei Riders as Kaito decides to join him. He takes Kaito to Futo, meeting up with Shotaro at the Narumi Detective Agency as he offers the young Rider to help the detective on his case. Later, Tsukasa approaches Takumi, asking him to join the battle against Badan. Takumi refused until he was attacked by Badan's monsters. He arrived to fight them until Kamen Rider Fifteen appears to attack him before Decade retreats. Meeting up with Shotaro in Futo, Tsukasa asks the detective to join the battle against Badan and Shuu's origins, which Shotaro would inform him about the boy. Tsukasa went to the lighthouse as he noticed that his mother, Saki looking at the picture with the note that Shuu wrote as she blamed herself for his death. Decade arrived where Shuu was and sent the boy to meet with his mother while Gaim distracts Fifteen. However, they were attacked by Badan's monster until Black and Black RX finished them off. Thanking both Riders, however their next target would be the Heisei Riders as Shotaro arrived to distract both Riders. Once they reached the lighthouse, Shuu was about to meet up with Saki, however Fifteen appears to retrieve his son as Tsukasa transformed to fight Fifteen. Overpowered by Fifteen, Gaim arrives to fight him, but failed to save the boy. Kouta was furious about Tsukasa not knowing Shuu's feelings. Tsukasa would gather the remaining Heisei Riders as Kouta and Takumi would join him. Once the remaining Riders arrive, both sides attack as Decade and 2 were defeated by each other. However all the Riders were freed thanks to Gaim as they (along with Kyoryu Red & the ToQgers) started to battle the Badan Empire. Decade freed Shuu from the machine as the ship was destroyed by Wizard, Faiz, and X. After battling the Badan Empire, Hongo stated that their battle wasn't over as the Rider War continues. However the Showa Riders admit their defeat after seeing Gaim protecting a flower as they would congratulate the young Riders. Sometimes later, Tsukasa visits the lighthouse and looked at the photo of Shuu that he took.

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 Kamen Ride Card on his helmet, embedded in the Decade Crown, and the others' Kamen Ride Cards on his chest.
- Decadriver - Tsukasa transforms into Decade through the use of the Decadriver (ディケイドライバー Dikeidoraibā?) 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.
- Ride Booker - Decade's primary weapon is the Ride Booker (ライドブッカー Raido Bukkā?) which has three modes:
- Book Mode (ブックモード Bukku Mōdo?): While in Book Mode, the Ride Booker holds the Rider Cards that Decade uses in his arsenal.
- Gun Mode (ガンモード Gan Mōdo?): In Gun Mode, the Ride Booker's finishing move is the Dimension Blast (ディメンションブラスト Dimenshon Burasuto?).
- Sword Mode (ソードモード Sōdo Mōdo?):In Sword Mode, the Ride Booker's finishing move is the Dimension Slash (ディメンションスラッシュ Dimenshon Surasshu?). When fighting Gyūki, Decade briefly fought as Kamen Rider Ryuki with a red bullfighting cape adorning the blade of Sword Mode.
- K-Touch - The Final Kamen Terminal K-Touch (ファイナルカメン端末ケータッチ Fainaru Kamen Tanmatsu Kētatchi?) 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.

Final Attack Ride Cards
The K-Touch is a device designed to allow Decade access to his Final/Complete form, through a process known as Final Kamen Ride. The activation code is as follows:
The K-Touch replaces the central component of the Decadriver, moving the scan port to Decade's right hip.
The K-Touch also allows Decade Complete to access the strongest forms of the other 9 Riders represented on it's face, by merely touching the Rider's insignia, followed by the "F" button in the top right corner. These facsimiles are most often used only for their own Final Attack Rides in tandem with Decade, then vanish.
