**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*, Masked Rider Decade), who is the main protagonist and eponymous character of the Kamen Rider Series *Kamen Rider Decade*.

He's one of the Kamen Riders debuting in DZ2K19. He also makes an appearance in Story Mode, where his world is under attack by the Mishima Zaibatsu.

## 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 and have been shown to foreshadow events, acting as a sign to show that he does not belong to the world he is in. As Decade, he was 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. He is quite cocky as he often taunts people from time to time.

Before the start of his series, it seemed as the leader of Dai-Shocker, Tsukasa was a ruthless and unforgiving man who easily tortured and killed people with little to no remorse as hinted through other's dialogue.

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. He also tends to tell American jokes from time to time that sometimes scares others.

Despite having these less than admirable traits, Tsukasa isn't all bad as he tries to save the innocents as Decade. He also taught all the A.R versions of the Main Riders a valuable lesson while learning a lesson or two himself. He also seems to care for the people close to him as he saved his sister from Tsukikage's influence. He was also the one who helped give Shotaro closure as well as helped Haruto when he was in doubt.

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.

## History

### Early LifeEdit

Ten years before the start of the series, Tsukasa's parents died and he was left with the Kadoya family butler, Tsukikage, to raise his younger sister, Sayo. Because she was afraid to go outside, she discovered the ability to open up dimensional walls. Tsukasa took advantage of this and he discovered he could do it as well and used this ability to explore different worlds, while she stayed cooped up in her room.

In his teens, he was appointed Grand Leader of Dai-Shocker and accepted the position because as Sayo explained in the movie, he thought "it would be fun". After being given the Rider Booker and DecadeDriver, he set off to subjugate the Riders in all the different A.R. Worlds one year before the start of the series. The shock of traveling through the A.R. Worlds caused him to lose his memories and he wound up in an A.R. World where Natsumi Hikari lived with her Grandfather without any memories of his history, other than how to fight and that he was sure it was not 'his' World.

### Becoming DecadeEdit

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 kaijinbefore 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' 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 to the other worlds to stop the dimensional chaos inflicted on his own world by meeting the Riders of each of the other dimensions while the rest of the Main Riders freeze time in the meanwhile. Rider War (episode)

## Trivia

* Despite being the hero and protagonist of Decade, Tsukasa may be considered as a villain considering that he was the one that destroyed most of the Heisei 1 Riders, giving him the name: Destroyer of Worlds. However, since Wizard, he plays a heroic role. That would mean that he's Neutral.
* Tsukasa is one of three Kamen Riders that can go back in time. The other is Sougo Tokiwa, aka Kamen Rider Zi-O and Geiz Myokouin, aka Kamen Rider Geiz.
* Tsukasa is the last Kamen Rider from the first Heisei phase, which led to the second Heisei phase, where Shotaro and Phillip are the first ones by technicality.
* Tsukasa is one of five Kamen Riders to appear outsider of the Kamen Rider franchise. The other two are Momotaros, Shinji, Emu and Yoko Minato. Tsukasa became a playable character in Injustice 2.
