History Edit

For all the canonical information of this character, see Tsukasa Kadoya at Kamen Rider Wiki.

Personality Edit

Tsukasa, as the way he is depicted in his TV series, remains all the same in the story; he is self-righteous and hypocritical who does not seem to know his past. In Metroid: Kamen Rider Generations, he also appears to be flighty, carefree, arrogant and condescending; as shown with his interactions with Samus Aran, whom he constantly foils her missions. However, he seems to be aware of Samus's intent of hiding in the present was to prevent the Galactic Federation from tailing her, this also shows Tsukasa is not above belittling the bounty hunter, nor seeing her just as an enemy from the future. Tsukasa's photos are usually badly developed, despite his claims to "capture everything around the world"; whenever he takes a picture of Samus, they began to develop well instead of blurring out.

Tsukasa seems to have amount of respect and reverence towards the Chozo, it is shown that him and Kotaro Minami were chosen to protect Samus all along at the Old Bird's approval. Given to the Old Bird's prophecy of Decade as the Destroyer of Worlds, he is the one who brought forth pestilence and destruction against the Galactic Federation for their corruption and conspiring to create bioweapons.

Despite being the anti-hero towards Samus, Tsukasa has a good side, developing bonds to those who are close to him, and even providing a good advice to Samus of what it means to protect humanity even without allowing a world to be destroyed as well as Mitsuzane in regards to his feelings towards the bounty hunter. He also seems to show a little distaste towards the Galactic Federation not only they are intent to capture Samus, but he detests them for creating weapons of mass destruction, an ideology shared with Samus's commanding officer, Adam Malkovich.

Given to Tsukasa's background with Dai-Shocker, he is also prone to commit henious acts. In the story, one such example where he holds Dr. Madeline Bergman hostage and subsequently executes her in cold blood after his cover is blown.

Trivia Edit

  • Decade's role in the story is similar to the SA-X from Metroid Fusion, who apparently tries to hunt down Samus. Unlike the SA-X, Decade appears to be confrontational.
  • Decade is one of the few Kamen Riders who can match Samus' skills when in her suit or not without the need of using a Final Form. Others being are Drive, Faiz, Kabuto, Ghost, Kiva, and Wizard.
  • Decade has some similarities to Samus herself according to how he started in his own series.
    • When Tsukasa became Decade, he learns that he lost his powers; presumably have used all of his Kamen Ride Cards, much like Samus starts her mission without her power ups.
  • Masahiro Inoue, Tsukasa's actor, is shown to play Super Mario Maker, originating from the sister franchise of Nintendo, the Super Mario series. Some of his stage designs are homages to his background as Kamen Rider Decade, which are almost impossible to clear due to presence of several traps. One of his stages, the "Nine Worlds" are also a homage to his season, and has caricatures of Narutaki and Kamen Rider Chaser on the said stage. [1] This is likely due to the fact that Tsukasa can put Samus to a corner without any trouble, regardless of the Kamen Rider he changes into, or in Complete Form.
  • Tsukasa when untransformed, he uses more on kicking, due to the fact that Masahiro Inoue himself is an actual real-life practioner of Tae Kwon Do.
