List of Kamen Rider Decade characters in the Nine 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 Nine Worlds (9つの世界, Kokonotsu no Sekai) are the A.R. Worlds that are based on the previous entries of the Kamen Rider Series that have aired during the Heisei period of Japanese history. Each differs in some way from the series on which it was based.
World of Kuuga
The World of Kuuga (クウガの世界, Kūga no Sekai) is the version of reality where Kamen Rider Kuuga takes place. It was the world where Yusuke Onodera originated from before he joined Tsukasa in his journey. The backdrop used to arrive in this world shows a city with police cars and Mount Hitoki (灯溶山, Hitoki-yama) in the background. Within this A.R. World, Tsukasa assumes the guise of a police officer with the talent of understanding and speaking the Gurongi language.[1][2][3][4][5][6]
Ai Yashiro
Ai Yashiro (八代 藍, Yashiro Ai), referred to as "Big Sis" (あねさん, Ane-san) by Yusuke, is a detective and the leading operative of the police force formed to fight the Gurongi. She mistakes Decade for "Unidentified Life Form #10" (未確認生命体十号, Mikakunin Seimeitai Jūgō) after Decade destroys Baberu.[3][4] While investigating the lair of the Gurongi to take out the resting Gamio, she and her group are overwhelmed by the miasma caused by the Gurongi leader's revival. However, Yusuke is unable to save her in time because the poison she breathed in later killed her. Prior to her death, she makes Yusuke promise that he will fight in order to protect everyone's smiles.[5][6]

N-Gamio-Zeda
Wolf Monster N-Gamio-Zeda (オオカミ種怪人 ン・ガミオ・ゼダ, Ōkami Shu Kaijin N Gamio Zeda) is the king of the Gurongi in the World of Kuuga;, he is also called "The Ultimate Darkness" (究極の闇, Kyūkyoku no Yami). He refers to himself as otherworldly because he should have never been revived, a fact that even he seems to believe, wondering why he was awakened. He is sealed and the Gurongi are attempting to unseal him with a Gegibasu Gegeru (ゲギバスゲゲル, Gegibasu Gegeru, Sacred Game), targeting five police women without spilling blood to revive him. Though they obtain four kills, Tsukasa uses Ai as bait to lure the Gurongi out and gives her a nose bleed to ruin the Gegeru.[3][4] The effects of the distortion revive Gamio anyway, and he uses his power to convert every human corpse within his Miasmic aura into a Gurongi. Although his ultimate goal is to have his sired Gurongi destroy each other, Gamio is destroyed by Kuuga and Decade performing a combo attack.[5][6]

Worlds, but later changes his mind when the Fangire betrayed them to Dai-Shocker.[11][12] After defeating Super Apollo Geist, the convergence of the worlds continues and the World of Kiva and Wataru disappear.[13][14] However, in Kamen Rider × Kamen Rider W & Decade: Movie War 2010, he is resurrected after Tsukasa has been killed by Kamen Rider Kiva-la.

He was exiled for loving a human woman who gave birth to his half-breed successor, Wataru. Seeing the coexistence and peace between the two races as nothing more than a farce for his son's sake, the Beetle Fangire breaks the peace by attacking humans to gather their Life Energy and reclaim his title, even stealing Kivat from Wataru.[7][8] His actions of removing the law to restart past conflicts between the two races provide the motivation for Wataru to step up and truly claim his place as King of the Fangires. In the end, he is weakened by Decade's Kiva Arrow, then fatally wounded by a Dimension Kick/Darkness Moon Break combo. Revealing that he knew of the Fangire's true identity and intent before he dies, Tsukasa plays a final song for him before the man shatters.[9][10]

Together with Tsukasa, Momotaros regains his true form and they destroy the Alligator Imagin, the force behind the Mole Imagin attacks who he believed caused the crisis.

For an unknown reason, the Tarōs have lost the ability to exist outside of time and in normal space, but they can now possess anyone at will in order to transform into Den-O. Urataros, Kintaros, and Ryutaros all possess Tsukasa, before possessing Natsumi and using her body to transform into Den-O to fight Decade, believing he's to blame for what is occurring.[31][32] After Kohana disciplines the three from jumping to conclusions and using Natsumi's body, the three remained on the DenLiner. Once Momotaros returns to the DenLiner and is reunited with Ryotaro and Kotaro. Kotaro mentions the Oni Brothers being behind the distortions in their world, just as three Tarōs disappear with Momotaros, finding themselves in 1930, where they hid by possessing the original Arms Monsters of Kamen Rider Kiva and became rice thieves. Rescued by the DenLiner crew, they join the battle on Onigashima where they possess the summoned Kamen Riders G3, Caucasus, Ohja.[33][34][35][36] Like Momotaros, the Tarōs also change the appearance of any person they possess: Urataros dresses them in a suave way (Tsukasa, for example, wears a white tuxedo and top hat under his possession), Kintaros gives them a feudal Japan-era look, and Ryutaros gives an 80s' hip hop style to the person, making him/her able to breakdance.

As a result, Hibiki adopts a lazy and rude attitude to most people, wears modern clothing, and even attempts to drive Asumu away in an attempt to retire from being an Oni. It is only when Kuuga is about to get killed by a Tengu Makamou that Hibiki decides to assume his Oni form and transforms into Gyuki as a result, wounding Ibuki and Zanki before being driven away by their pupils.[41][42] Knowing that he will no longer be able to assume his human or Oni form again should he transform into Gyuki, he gives up his Transformation Tuning Fork Onkaku to Daiki Kaito to give to Asumu, who becomes the new Hibiki and must slay his former master as his final request.[43][44]
Hibiki is portrayed by David Ito (デビット伊東, Debitto Itō), while his Gyuki form is voiced by Keikō Sakai (酒井 敬幸, Sakai Keikō).
Makamou
The Makamou (魔化魍, Makamō) are an assortment of monstrous creatures that usually dwell in the rural areas of Japan and consume any human beings as food. There are two main variations of this group: the bestial Giant Type and the humanoid Summer Type.[41][42][43][44] In the first episode, Makamou such as the Bakegani and Ooari attack Natsumi while others like the Ubume were involved in the all-out battle among the monster groups that destroys the world.[1][2]
- Kappa (カッパ): A Summer Type snapping turtle/frog-like Makamou, it was first one that Tsukasa and company encounter before Asumu arrives to fight it. In the end, the Kappa is destroyed by Decade using Kabuto's Rider Kick.
- Bakeneko (バケネコ): A trio of Summer Type humanoid cat Makamou. While the first two are destroyed by Zanki and Ibuki, the last one evades them before being destroyed by Decade's Dimension Kick.
- Ooari (オオアリ, Ōari): A Giant Type ant Makamou.
- Tengu (テング): A Summer Type ape/parrot Makamou that attacked Hibiki and Asumu, overpowering Kuuga until Hibiki assumes his Oni form and destroys the Makamou.
- Ubume (ウブメ): A Giant Type oarfish Makamou with white bird wings.
- Bakegani (バケガニ): A Giant Type swimming crab Makamou, larger than the average type with more pincers. It is released by Takeshi Asakura/Kamen Rider Ouja and appears with Narutaki riding on it once Gyuki is destroyed. The Bakegani is destroyed through the combined efforts of Hibiki, Decade, Diend, Amaki, Todoroki, Ibuki, and Zanki.
