Tsukasa Kadoya

Personality
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.

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!"

Lore
Tsukasa travels around to all the known (and some unknown) Universes by way of his crazy magical Photo Studio. He's known to randomly spawn clothing depending on what Universe he lands in, in hopes of fitting in more so that he can seemingly make friends and take horrible photographs of everyone he meets.

Abilities/Equiptment
Tsukasa outside of his suit has little to no actual powers, aside from being able to take photographs with his Camera Obscura, and activating the Decadriver.

Machine Decader
The Machine Decader is Decade's personal Honda DN-01. Like Decade himself, the Decader can assume the form of the respective Rider's motorcycle. It exhibits this ability when Decade (as Faiz) transforms the Decader into the Autovajin.

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.

Decade's primary weapon is the Ride Booker (??????・ Raido Bukka) which has three modes: the default Book Mode (????・, Bukku Modo ), which is placed on the left side of his belt and holds the Rider Cards that Decade uses in his arsenal, Gun Mode (???・, Gan Modo) which can be used to execute the Dimension Blast (???????????, Dimenshon Burasuto) finisher and Sword Mode (?・?・, Sodo Modo) which can be used to execute the Dimension Slash (????????????, Dimenshon Surasshu) finisher.

Rider Cards
Decade has card-based weaponry and powers: the Rider Cards. However, due to a seal placed on them all, Tsukasa travels across the Multiverse to undo the seals and regain the abilities the cards endow.

Kamen Ride Cards


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.

Final Attack Ride Cards


The Final Attack Ride Cards (?????????????・, Fainaru Atakku Raido Kado) 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 (????????????, Kyoka Dimenshon Kikku).

Alongside Double CycloneCyclone and Double JokerJoker, Decade executes a triple Rider Kick called the Triple Extreme (?????????・, Toripuru Ekusutorimu).

In All Riders vs. Dai-Shocker, a variation of this card is the Final Kamen Attack Form Ride Card (??????????????・????・, Fainaru Kamen Atakku Fomu Raido Kado) which is used while Decade Complete Form Jumbo Formation is active. Decade performs the Final Dimension Kick (???????????????, Fainaru Dimenshon Kikku), a variation of the Dimension Kick, transforming the Showa and Heisei Riders into Kamen Ride cards for Decade to travel through as opposed to Final Attack Ride cards before hitting the target.

In All Riders vs. Dai-Shocker, when Tsukasa "loans" the Kiva Arrow to Momotaros, the attack is called Momo Fang (??????, Momo Fangu), labeled by Momotaros as "Our Finishing Attack, Final Attack Version" (???????ｷ??????????・??, Oretachi no Hissatsu Waza: Fainaru Atakku Bajon).

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.

K-Touch


The Final Kamen Terminal K-Touch (???????????・??, Fainaru Kamen Tanmatsu Ketatchi) 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. In Hyper Battle Video, K-Touch seemed has a function to summon all previous Heisei Riders in their respective ultimate form without Decade pressing the buttons of the K-Touch.
