Tsukasa Kadoya (A New Decade)

1="I'm just a passing-through Kamen Rider. Remember that!"

- Tsukasa's answer when asked who he is

2="This might tickle a bit."

- Tsukasa's warning before using a Final Form Ride Card on a Legend Rider for the first time.

Tsukasa Kadoya (門矢 士) is Kamen Rider Decade (仮面ライダーディケイド), who is one of the main protagonists of A New Decade.

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.

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.

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！).

Tsukasa uses a "Decade Pink" Blackbird Fly 135 .

Powers and Abilities

 * Peak Human Physicality/Reflexes: As the former leader of Dai-Shocker, it is presumable that Tsukasa was skilled at fighting even before the start of his series. In fact, it seems that Tsukasa's abilities far surpass a normal human since he defeated two high level Orphnochs in tennis and used a card as a shuriken to cut a chain. In theory, it is possible that Tsukasa may not be a normal human as he was the Great Leader of Dai-Shocker with most of the High Ranking Members being powerful creatures and cyborgs themselves.
 * Enhanced Memory: Even after losing his previous memories, he could easily fight against most of the A.R Riders while holding back. By transforming into Decade, he could seemingly use all of the other main Rider's powers (even when he has no idea of how his Rider System and the previous Rider Powers work while not able to use them as effectively or skillfully as the originals) and fight against his former subordinates as well as other monsters.
 * Interdimensional Travel: An otherworldly human himself, Tsukasa can travel within worlds via Dimensional walls. However, the downside is that he is unable to take pictures perfectly in the world he resided unless if he is in his true world. Also to be noted is that the people taken by said pictures often suffer in one way or another.
 * Neo Worlds abilities: Due to having no real home of his own, whenever Tsukasa travels to another world, he takes on a role within it, granting him different abilities as well as all necessary needs to take on that role (IE clothes, documents etc.).
