Tsukasa, Wataru, Kaitoh and Yusuke fight Super Apollo Geist, who then takes Natsumi hostage and flees. Kenzaki Kazuma appears, confronting Tsukasa before turning into Kamen Rider Blade King Form to fight and easily defeat Decade. Meanwhile, Super Apollo Geist resurrects the Beetle Fangire, Paradoxa Undead, Tiger Orphnoch, Buffalo Lord Taurus Ballista, Alligator Imagin, and the Phylloxera Worm. Under Kenzaki's advice, Wataru and Asumu then attack Tsukasa in an attempt to preserve their own worlds, but Yusuke intervenes and defends him, saying that Tsukasa had saved their A.R. Worlds. This allows Tsukasa to rescue Natsumi, who is about to have her life energy absorbed by Guy.

Seeing his good action, Kiva and Hibiki work together to take out the resurrected villains, while Diend and Decade destroy Super Apollo Geist. After Apollo Geist's destruction, Natsumi soon recognizes that she is in the exact place where her dream of the Rider War takes place. Suddenly, Kiva and Hibiki disappear as the Nine A.R. Worlds have been destroyed, with only Yusuke Onodera surviving. Tsukasa is suddenly transported to the dimension where he had spoken with the mysterious young man before he began his journey. He tells Tsukasa that he did not save the Nine Worlds before transforming into Kamen Rider Kiva and attacking him.

Soon, Tsukasa finds himself back in the World of the Rider War, confronted by the eight of the nine other Heisei Kamen Riders. Kivala then bites Yusuke, turning him into a black-eyed Kamen Rider Kuuga Ultimate Form. The Rider War commences, and Diend suddenly aims the Diendriver at Decade at pointblank range.

Kiva Form

Kiva Form (キバフォーム) is Kiva's default form, accessed through a bite from Kivat, whose status determines Kiva's ability in a battle. He is able to see in the dark with his visor called the Omnilens (オムニレンズ). In this form, Kiva can use any of the Fuestles, with the Wake Up Fuestle to open up the Catena Chains on his right leg known as the Hell's Gate (ヘルズゲート) made of Lucifer Metal (ルシファーメタル) so Kiva can use his Rider Kick the Darkness Moon Break (ダークネスムーンブレイク). The kick has an impact of 30,000 kg, enough to leave a crater in the shape of a bat's wings (Kiva's insignia) on any surface upon contact; the glass body of a Fangire shatters instantly. Kiva can also perform a stronger variation of the Darkness Moon Break when engulfed in Castle Doran's fire. When the Darkness Moon Break is performed, day turns into night and a crescent moon appears in the sky. Its motif is that of a Vampire bat.

Garuru Form

Garuru Form (ガルルフォーム) is Kiva's form accessed from being energized by the Garuru Saber. In this form, the Omnilens and Kiva's chest/left arm armor turn a shade of blue called Garuru Cobalt (ガルルコバルト) which places Kiva under the influence of Garuru. This form's power is linked to the phases of the moon, and is at its peak when the moon is full. The Garuru Form, is capable of manipulating sound, has increased speed and cunning due to the form's animalistic ferocity and is able to perform the Garuru Howling Slash. When it is performed, day turns to night and a full moon appears in the sky, as it references a human's transformation into a werewolf. Its motif is that of a werewolf (狼男).

Basshaa Form

Basshaa Form (バッシャーフォーム) is Kiva's form accessed from the Basshaa Fuestle and granting him access to the Basshaa Magnum. In this form, the Omnilens and Kiva's chest/right arm armor turn a shade of green called Basshaa Emerald (バッシャーエメラルド) which places Kiva under the influence of Basshaa. While in this state, Kiva loses most of his strength and ability, but gains a mastery of long range combat and is able to analyze an opponent's weak point to target with accurate marksmanship. Basshaa Form can also manipulate water, able to create rain as well as a pool of water necessary to perform the Basshaa Aqua Tornado. When it is performed, day turns to night and a half moon forms in the sky, as it references the change ebb and flow of the tides during its phase. Its motif is that of the Gill-man (半魚人).

Dogga Form

Dogga Form (ドッガフォーム) is Kiva's form accessed from the Dogga Fuestle and granting him access to the massive Dogga Hammer. In this form, Kiva's entire upper body gains bulky armor and the Omnilens turn a shade of violet called Dogga Purple (ドッガパープル), under Dogga's influence. In this form, Kiva loses most of his speed but gains unbelievable strength, able to overpower a Fangire easily. Dogga Form is able to manipulate electricity, using it as part of his finisher, the Dogga Thunder Slap. The Dogga Hammer can see through the invisibility of Fangires. When it is performed, day turns to night while a hazy moon and thunderbolt form in the sky, the latter referencing its motif of Frankenstein's monster (フランケンシュタインの人造人間) and how it was brought to life.

DoGaBaKi Form

DoGaBaKi Form (ドガバキフォーム), shortened from "Dogga/Garulu/Basshaa/Kiva Form" (ドッガ・ガルル・バッシャー・キバフォーム), is Kiva's rarely seen form accessed by the summoning of all three Arms Monsters. In this form, Kiva's left arm turns into the Garuru Arm (ガルルアーム), his right arm turns into the Basshaa Arm (バッシャーアーム), and his upper body turns into the Dogga Breast (ドッガブレスト). In this form, Kiva can use all three Arms Monster weapons at once and the Darkness Moon Break. However, due to the danger it presents to Kiva and the Arms Monsters, Kiva can only assume this form for five minutes before its power becomes lethal.

Emperor Form

Emperor Form (エンペラーフォーム) is the true form of Kiva referred to as the Golden Kiva (黄金のキバ) and the most powerful form at Wataru's disposal. The fifth form accessed, the first emergence of Emperor Form comes about from the reaction to Wataru's rage from the harm coming to Mio, his girlfriend, which summons Tatsulot to awaken the form. By pulling the switch on Tatsulot, Wataru can activate Tatsulot's Imperial Slot (インペリアルスロット) and activate one of several "Fever" finishing attacks through a roulette system. With this form, Kiva can destroy both the body and the soul of a Fangire. Soon after gaining this form, Wataru gradually abandoned the use of his other forms. Emperor Form initially appeared in promotions for Kamen Rider Kiva: King of the Castle in the Demon World at the Tokyo Toy Show 2008. On the album SUPERNOVA by TETRA-FANG, Emperor Form is referred to as "Empire form."

Flight Form

Resulting from infusing his own desire into the Bloody Rose, Wataru's Fangire nature is triggered as Kiva transforms from Emperor Form into Flight Style (飛翔態), a dragon-like form called the Emperor Bat (エンペラーバット) which is similar to the Fangires' ability to become Sabbats. In Kamen Rider Kiva: King of the Castle in the Demon World, Arc forces Wataru to assume the form in an attempt to kill his father, Otoya Kurenai, only for Wataru to access Flight Style later to defeat him. Flight Style uses the blades on its wings called the Sonic Claws (ソニッククロー) to perform the Demon Pliers (デモンプライヤー) attack and breathes the Hell's Flame (ヘルズフレイム, Heruzu Fureimu?) from its Big Jaw (ビッグジョー). These abilities come into play for its finishing attack, the Bloody Strike (ブラッディストライク)

DoGaBaKi Emperor Form

DoGaBaKi Emperor Form (ドガバキエンペラーフォーム) is a form seen the Adventure Battle DVD, when Kiva accesses Emperor Form while in DoGaBaKi Form. In this form, Kiva can use all three Arms Monster weapons and execute the DoGaBaKi Emperor Break.
