Fictional character biography
Tatsulot was resting inside the ceiling of Castle Doran until Wataru's rage from the harm coming to Mio awakens him. After his initial appearance, Tatsulot would go on to live in Wataru's house. Sometimes appearing without being summoned by the Tatsulot Fuestle. He and Kivat do not usually get along because of their differing attitudes. Later, Tatsulot joins Kivat telling the viewer random historical facts while scenes from the previous episode play in the background, although his historical knowledge is somewhat limited. He would later help narrate the current events in the 2008 storyline with Kivat.

As Transformation Rotation Brace Tatsulot
Tatsulot also called the Transformation Rotation Brace Tatsulot (変身回転ブレスタツロット, Henshin Kaiten Buresu Tatsurotto) unleashes Kiva's Final Wake Up (ファイナルウエイクアップ, Fainaru Ueiku Appu), evoking his transformation to Emperor Form. While Kiva is in Emperor Form, Tatsulot's Imperial Slot (インペリアルスロット, Inperiaru Surotto) utilizes a roulette system to use one of four Fever themed attacks, with Tatsulot able to attach to each of the Arms Monster weapons for more power.


 * Wake Up Fever (ウエイクアップフィーバー, Ueiku Appu Fībā) activates Emperor Form's Emperor Moon Break (エンペラームーンブレイク, Enperā Mūn Bureiku) or DoGaBaKi Emperor Form's DoGaBaKi Emperor Break (ドガバキエンペラーブレイク, Dogabaki Enperā Bureiku). Kiva's legs are surrounded by energy blades similar in shape to the "wings" of Kiva's insignia. With these blades, Kiva can hit a variety of kicks, including a bicycle kick with the blades stabbing through the target, an attack sometimes preceded by a front dropkick, and a jumping roundhouse kick. As DoGaBaKi Emperor Form, Kiva can hit the Emperor Moon Break combined with fire, water and lightning.
 * Garulu Fever (ガルルフィーバー, Garuru Fībā) summons the Garulu Saber as Tatsulot connects to the hilt, allowing Kiva to be shot into the air for the Emperor Howling Slash (エンペラーハウリングスラッシュ, Enperā Hauringu Surasshu) overhead slash attack. This attack can also allow both ends of the Garulu Saber to become fiery blades for an alternative finisher.
 * Basshaa Fever (バッシャーフィーバー, Basshā Fībā) summons the Basshaa Magnum as it connects to Tatsulot, allowing Kiva to execute the Emperor Aqua Tornado (エンペラーアクアトルネード, Enperā Akua Torunēdo) attack. This finishing move is not featured in the series' run.
 * Dogga Fever (ドッガフィーバー, Dogga Fībā) summons the Dogga Hammer as it connects to Tatsulot, allowing Kiva to execute the Emperor Thunder Slap (エンペラーサンダースラップ, Enperā Sandā Surappu) attack, with Tatsulot creating an orb of electricity that Kiva bashes with the hammer to put a Fangire in its fragile state before executing a smashing deathblow.
