List of ''Kamen Rider Decade'' characters in the New Worlds

The characters of Kamen Rider Decade exist amongst various iterations of reality within the series referred to as an A.R. World (Another Rider's/Alternate Reality World). The New Worlds (新たな世界, Aratana Sekai) are the A.R. Worlds that are not based on a previous entry of the Kamen Rider Series from the Heisei period.

World of Negatives

The World of Negatives (ネガの世界, Nega no Sekai) is a parallel world created in the image of the one Natsumi comes from, but is actually home to monsters who assume human form and serve Dark Riders (ダークライダー, Dāku Raidā) who hunt down any real humans that are still alive. The backdrop used to enter this world depicts the destruction of the first world caused by the monsters' conflict among themselves, the scene itself matching up with the mother and child running from the flames in the first episode, just before the event was frozen by Wataru Kurenai. In this A.R. World, Tsukasa becomes a contest winner and male model. Daiki's treasure in this world is the K-Touch, which ultimately ends up in the hands of Tsukasa, allowing him to gain access to Decade Complete Form.^{[1][2][3][4][5][6]}

Otoya Kurenai

Otoya Kurenai (紅 音也, Kurenai Otoya) is a young man who leads the Dark Riders, using his connection to Kivat-bat the 2nd to become Kamen Rider Dark Kiva (仮面ライダーダークキバ, Kamen Raidā Dāku Kiba). Revealing himself to Tsukasa while thanking him for saving their world, Otoya has an agenda to have Tsukasa become the king of the World of Negatives, testing him personally to confirm it.^[3][4] But his plan fails as Tsukasa refuses and defeats his allies, leaving Otoya as the only surviving Dark Rider.^[5][6]

Kouhei Takeda (武田 航平, Takeda Kōhei) reprises his role as Otoya Kurenai from Kamen Rider Kiva.

Natsumi

The World of Negatives' Natsumi (ネガの世界の夏海, Nega no Sekai no Natsumi) is the World of Negatives counterpart of the real Natsumi Hikari and one of the few remaining humans in the World of Negatives. She confronts her counterpart in an attempt to warn her of Otoya's scheme, only to be forced to dig up the K-Touch she had hidden. She eventually gives her goodbyes to Natsumi while entrusting the K-Touch to Tsukasa, remaining in her world out of hope for the future.^[5][6]

Though ordered by Otoya to keep an eye on Natsumi rather than kill her, he intentionally decides to attack Natsumi, resulting in Dark Kiva beating him merciless. Alternative is then later destroyed by Diend.^[3][4][5][6] Although referred to as Alternative, the suit is actually that of Alternative Zero (オルタナティブ・ゼロ, Orutanatibu Zero).

Alternative and Tanaka are portrayed by Masayasu Kitayama (北山 雅康, Kitayama Masayasu).

World of Diend

The World of Diend (ディエンドの世界, Diendo no Sekai) is the world where Daiki comes from, similar to the World of Blade due to the presence of Undead known as Roaches (ローチ, Rōchi). More specifically, it seems to be related to the film Missing Ace, due to being home to the three Ace Riders (even played by the same actors) and Jashin 14 (known as the Fourteen), characters exclusive to the film. But as the world is dominated by the Roaches and their leader Fourteen, the human populace is mostly brainwashed into a state of euphoria and conditioned to see Kamen Riders as disruptors of the peace, and anyone who disobeys the rules, even slightly, has their free will completely removed. The backdrop used to enter this world depicts a wanted poster with Diend's symbol on it in the foreground and a cityscape in the background. Within this A.R. World, Tsukasa assumes the role of a traveling salesman before being labeled a criminal. Daiki's treasure in his homeworld is freeing his brother from the control of Fourteen, only to learn he was not controlled at all.^{[5][6][7][8][9][10]}

Junichi Kaito

Junichi Kaito (海東 純一, Kaitō Jun'ichi) is Daiki's older brother within his home world. Like Daiki, Junichi is also a Kamen Rider, Kamen Rider Glaive (仮面ライダーグレイブ, Kamen Raidā Gureibu), setting up the operation to overthrow Fourteen. However, Junichi was actually a double agent who worked to flush out the last two Kamen Riders of their world until Daiki unknowingly captured him, and as a result, played the role as Fourteen's puppet right hand in charge of the area management committee. However, once Fourteen is destroyed, freeing everyone else from the brainwashing, Junichi reveals the truth with intent to be the next Fourteen. In spite of not being able to kill Daiki, with Tsukasa affirming he still has his free will, Junichi considers his brother dead to him and leaves.^{[7][8][9][10]}

Yuuki Kuroda (黒田 勇樹, Kuroda Yūki) portrays Junichi Kaito, having portrayed a similar character in the film Kamen Rider Blade: Missing Ace.

Haruka Miwa

Haruka Miwa (三輪 春香, Miwa Haruka) is a young woman who resists Fourteen as Kamen Rider Larc (仮面ライダーラルク, Kamen Raidā Raruku). She took part in the operation to overthrow Fourteen and ended up escaping with Shin when the operation was a failure. Since then, she has been on the run from Fourteen's minions. She helps fill Tsukasa in on what is currently happening in her world.^[7][8]

Yoko Mitsuya (三津谷 葉子, Mitsuya Yōko) portrays Haruka Miwa, having portrayed a similar character in the film Kamen Rider Blade: Missing Ace.

Jashin 14

Jashin 14 (邪神14, Jashin Fōtīn) is leader of the Roaches and ruler of this world, assuming the human-like form of Fourteen (フォーティーン, Fōtīn) for his "ideal peace", turning humans into mindless slaves. He is a massive creature with multiple arms that floats through the air. He is destroyed by Decade in Complete Form with aid from Armed Hibiki, cutting him in half. After his demise, the Roaches vanish and everyone he'd brainwashed were set free.^{[7][8][9][10]}

Fourteen is portrayed by Takashi Ito (伊藤 高史, Itō Takashi).

Bossroach

Bossroach (ボスローチ, Bosurōchi) is one of the Roach enforcers who watch over the human race, whom he sees to be inferior. Bossroach resembles the Caucasus Undead. Bossroach is then destroyed by Decade Complete Form using Kiva Emperor Form's power.^[7][8]

Darkroaches

Darkroaches (ダークローチ, Dākurōchi) are Category Unknown Undead who are minions of Fourteen, going after any one who breaks the law. Many of them are killed by the Riders and when their master is destroyed by Decade and Armed Hibiki, the Darkroaches fade away into nothingness.

World of Shinkenger

The World of Shinkenger (シンケンジャーの世界, Samurai Sentai Shinkenjā no Sekai) is the reality in which the 33rd Super Sentai Series Samurai Sentai Shinkenger and all the Super Sentai series takes place. The backdrop used to enter this world resembles the ending credits sequence of Shinkenger, featuring two kuroko opening up a curtain to reveal artistic representations of the five main Origami. Because it is initially a world without Kamen Riders, the World of Shinkenger is not an A.R. World until Chinomanako obtains the Diendriver and transforms, becoming a distortion that threatens the world itself.^{[11][12][13][14]} The storyline takes place after Shinkenger Act (episodes) 20 and during Act 21, with the episodes airing on July 12 and July 19, 2009.^[15][16] Within this world, Tsukasa finds himself as one of the kuroko of the Shiba Household, discarding the guise when the distortion begins. Daiki's treasure in this world is the Ika Origami, which he steals in the teaser at the end of Shinkenger Act 20.

The Shinkengers

The Shinkengers (シンケンジャー, Shinkenjā) are six young men and women who use a special kanji-based power called Modikara (モヂカラ, Mojikara) to combat the evil Gedoushu as superpowered samurai.

The Gedoushu

The Gedoushu (外道衆, Gedōshū) are malevolent spirits that dwell in the Sanzu River. They enter the mortal world through gaps to inflict terror on the humans to allow the river to flood over both worlds. Their leading members live aboard the Rokumon Junk (六門船, Rokumonsen) and consist of Doukoku Chimatsuri, Tayu Usukawa and Shitari of the Bones. Under their control are the Ayakashi (アヤカシ) who enter the mortal world, assisted by the Nanashi Company.

Like Diend, Chinomanako Diend is armed with Kamen Ride Cards as well as Kaijin Ride Cards that allow him to summon the Moose Fangire and the Eagle Undead. He also summons Kamen Rider Blade, which brings to his downfall as Decade uses the Blade Final Form Ride card to turn him into Blade Blade, which Shinken Red wields. While Shinken Pink, Shinken Green and Shinken Gold defeat the Moose Fangire and Shinken Blue, Shinken Yellow and Kamen Rider Kuuga defeat the Eagle Undead, Chinomanako is destroyed by the teamwork of Decade Complete Form and Shinken Red, after being weakened by a combo Royal Straight Flush attack with Blade King Form. As with other Ayakashi being the basis of monsters from Japanese mythology, Chinomanako is the basis of the Mokumokuren (目目連).^[11][12]

Chinomanako is voiced by Ryūzaburō Ōtomo (大友 龍三郎, Ōtomo Ryūzaburō).

World of RX

The World of RX (RXの世界, Āru Ekkusu no Sekai) is the version of reality where Kamen Rider Black RX takes place. The backdrop used to arrive in this world features the Crisis Empire's battleship in the background. Within this A.R. World, Tsukasa originally wore a set of clothes that have him mistaken for Joe the Haze (霞のジョー, Kasumi no Jō) by Kotaro and the Crisis Empire. Daiki's treasure in this world is Apollo Geist's Perfecter.^[17][18]

Tetsuo Kurata reprises his role as Kotaro Minami in the character's World of Black incarnation.

World of Amazon

The World of Amazon (アマゾンの世界, Amazon no Sekai) is the version of reality where Kamen Rider Amazon takes place. By the time Decade arrives, he finds the world is under Dai-Shocker's control as they eliminate any resistance. As a result, the people do not trust each other, as they cannot tell who is and who is not aligned with Dai-Shocker. The backdrop used to arrive in this world depicts the Amazon Rainforest with Amazon in the middle of it. Within this A.R. World, Tsukasa wears the attire of a baseball player. Daiki's treasure in this world is the GaGa Armlet.^{[21][22][23][24]}

The backdrop used to enter this world depicts all nine of the Heisei Riders, the DenLiner, Dragredder, Castle Doran, and Ryokuōzaru rushing at Decade, mirroring the very opening scene of the series. In addition, all of the villains created for Decade make another appearance.^{[25][26][27][28]} Going into the World of the Rider War, the only "worlds" remaining are of Blade's, Kiva's and Hibiki's.

World of Decade

The World of Decade (ディケイドの世界, Dikeido no Sekai) is the version of reality that is the true home of Tsukasa Kadoya. It is the primary setting of Kamen Rider Decade: All Riders vs. Dai-Shocker. The backdrop used to enter this world depicts an old mansion that is the home of the Kadoya family.^[29] This A.R. World is neither one of the Nine Worlds nor the New Worlds. This is the world where Daiki got his first treasure, the Diendriver.

Sayo Kadoya

Sayo Kadoya (門矢 小夜, Kadoya Sayo) is Tsukasa's younger sister. She is a pianist and is protected by Nobuhiko Tsukikage due to her possession of the Stone of the Earth, which is the source of Dai-Shocker's travel between the A.R. Worlds. This allows her to become High Priestess Bishium (大神官ビシュム, Daishinkan Bishumu), whom Shadow Moon manipulated to hate Tsukasa and turn Yusuke into her puppet. After realizing that she has been used, she destroys the Stone of the Earth and later makes amends with Tsukasa before he leaves.^[29]

Sayo Kadoya is portrayed by Moe Arai (荒井 萌, Arai Moe). As a child, Sayo is portrayed by Momoka Ishii (石井 萌々果, Ishii Momoka).

Through his King Stone, embedded with the Stone of the Moon, Nobuhiko can transform into Shadow Moon (シャドームーン, Shadō Mūn). Once he ousts the former leader of Dai-Shocker, Tsukasa Kadoya, Nobuhiko becomes its leader as he leads the group to hunt down every Kamen Rider. In the end, though he overpowers Decade and Kuuga, Shadow Moon is defeated by Double and destroyed by the All Rider Kick. While shares the same name with Nobuhiko Akizuki, the original Shadow Moon from Kamen Rider Black, his surname "Tsukikage" means "Moon Shadow".^[29]

Nobuhiko Tsukikage is portrayed by Ryuichi Oura (大浦 龍宇一, Ōura Ryūichi).

Joji Yuki

Joji Yuki (結城 丈二, Yūki Jōji, read as "Joji Yu-ki" in "The Next Decade" PV) is a mysterious young man with a prosthetic arm. He was a scientist who worked for Dai-Shocker and was involved in the production of the Decadriver and the Diendriver. For unknown reasons, Yuki rebels against Dai-Shocker and is punished when the organization's leader at the time, Tsukasa Kadoya, orders the amputation of his arm.^[29] This has made him a wanted man in the World of Decade.^[30] Though he attempts to get his revenge on Tsukasa when he returns and is dethroned by Shadow Moon, Joji spares Tsukasa's life after seeing him no longer as the man he hated and encourages him to fight Dai-Shocker. He is able to remove his prosthetic arm to attach a powerful laser cannon.

The original Joji Yuki is the alter ego of Riderman (ライダーマン, Raidāman), who appears later in the All Riders vs. Dai-Shocker film. The Joji Yuki of the World of Decade does not transform into Riderman.

Joji Yuki is portrayed by musical artist Gackt, a character also portrayed in his music video for "The Next Decade". A redesigned Riderman costume was planned for the film (akin to the redesigns found in Kamen Rider The First and The Next), but was left out due to time constraints, with only the laser cannon made.

World of the Rider War (Movie War 2010)

In Kamen Rider × Kamen Rider W & Decade: Movie War 2010, the World of the Rider War takes on its true purpose and is home to the evil Super Shocker organization. The backdrop for this world now depicts the destruction of the Nine Worlds. Tsukasa is dressed in the same clothes from the first episode with a different hairstyle, but now transforms into Decade Violent Emotion. Daiki's treasure in this world is Tsukasa's rider deck.^[31]

Yuriko Misaki

Yuriko Misaki (岬 ユリコ, Misaki Yuriko) is a girl who lives in this A.R. World who meets Tsukasa during his rampage against the Kamen Riders. She follows Tsukasa, urging him along in his mission to be the destroyer of worlds. Like her namesake from Kamen Rider Stronger, Yuriko has the ability to transform into Electro-Wave Human Tackle (電波人間タックル, Denpa Ningen Takkuru). It is said that she died in a fight with the Bee Woman years in the past but due to having never found her place in the world, she still searches for it even in death. She finds her place with Tsukasa, the only one who cared for her. In the end, she sacrifices herself to mortally wound the Bee Woman with her Ultra Cyclone attack and save Natsumi from her. Now able to rest in peace having finally having found her place and avenged her death, she disappears.

Yuriko Misaki is portrayed by Alice Hirose (広瀬 アリス, Hirose Arisu).^[31]

Super Shocker

The evil Super Shocker (スーパーショッカー, Sūpā Shokkā) organization is formed from the last remnants of Dai-Shocker, with the destruction of the Nine Worlds and the destruction of Dai-Shocker. In addition to the high-ranking members Super Doctor Shinigami and Colonel Zol, other villains from the Kamen Rider Series make up the ranks of Super Shocker.^[31] They utilize the Super Crisis Fortress (スーパークライス要塞, Sūpā Kuraisu Yōsai) as their base.

Bee Woman

The Inhumanoid Bee Woman (ハチ女, Hachi Onna) was a bee-like cyborg with a rapier as her weapon, and previously a member of Shocker in Kamen Rider, being the one who killed Tackle while a member of Dai-Shocker. She is now one of the high-ranking members of Super Shocker, going after Natsumi until she is mortality wounded by Electro-Wave Human Tackle's Ultra Cyclone. The Bee Woman releases the Neo Organism to make her more powerful, only to be engulfed by it.

The Bee Woman is portrayed by Nao Oikawa (及川 奈央, Oikawa Nao).^[31]

Neo Organism

The Neo Organism (ネオ生命体, Neo Seimeitai) of Kamen Rider ZO is a pool of living fluid that relies on the very container its dwells in as its life support and create a grotesque Kamen Rider-like incarnation known as Doras (ドラス, Dorasu). Its personality is extremely childish and somewhat sadistic, though it appears it doesn't realize the true nature of what its doing, referring to its attacking the Kamen Riders as 'playing'. Super Doctor Shinigami seeks to revive the Neo Organism in order to destroy Kamen Rider Decade. But once revived, it is beyond Super Shocker's control as it consumes Bee Woman and creates Doras to fight the Kamen Riders. Though Doras is destroyed by a combined finisher from all the most powerful forms of the Nine World Riders, the Neo Organism takes control of the Super Crisis Fortress until it is destroyed. However, it survives and absorbs the Dummy Dopant to become the inhumanoid Ultimate D (アルティメットD, Arutimetto Dī, The letter D stands for "Doras" and "Dummy Dopant") before quickly meeting its end through Decade and Double's Triple Extreme Rider Kick.^[31]

The Neo Organism is voiced by Yūtarō Honjō (本城 雄太郎, Honjō Yūtarō), while Doras's vocal effects are provided by Keikō Sakai (酒井 敬幸, Sakai Keikō). As Ultimate D, he is also voiced by Toru Tezuka (手塚 とおる, Tezuka Tōru).

Super Shocker Combatmen

The Super Shocker Combatmen (スーパーショッカー戦闘員, Sūpā Shokkā Sentōin) are remodeled versions of the Dai-Shocker's footsoldiers, resembling the Shocker Combatmen and tending to scream out "Yeee" (イーッ, Ī). Like the Dai-Shocker Combatmen they are also able to assume missile-like forms.
