"Kill! I will kill you with my own hands!"
―Takashi's words before battling Kiva[src]

Kamen Rider Arc (仮面ライダーアーク Kamen Raidā Āku, Masked Rider Arc) is the main antagonist of Kamen Rider Kiva: King of the Castle in the Demon World.

He is the leader of the Legendorga race who was defeated by the original Kiva and sealed within a coffin.

When death row inmate, Takashi Sugimura (杉村 隆 Sugimura Takashi) stumbled onto his seal, the essence of the evil rider possessed him, preventing Sugimura from dying until Arc would rise with help from his minions.


As above stated, Kamen Rider Arc was a powerful leader of the Legendorga who led his race to glory, attacking any race that stood in his way. However the original Kiva stood against Arc and defeated him. However, Arc was not gone for good, and his essence was sealed within a coffin. Years later, the place where he was sealed became the ground for a prison, that included the mentally broken, Takashi Sugimura. When Sugimura tried to escape when the Zebra Fangire appeared, he came across Arc's coffin. Arc then took over Sugimura's body before Sugimura spent the next twenty years in prison. Curiously, he was sent to death several times but did not die due to Arc. In the present day, Arc's resurfacing commenced with the resurrection of his race. When the Legendorga brought Sugimura to Arc's castle, the demonic Rider was fully revived within him. Arc and his race commenced the takeover of humans and any race that stood in its way, while also targeting the current Kamen Rider Kiva, Wataru Kurenai. Eventually, Wataru and his father, Otoya Kurenai confronted Arc. Arc attempted to make Wataru his servant through the Legendorga baptism, becoming Kiva Flight Style. Otoya however, managed to get through to his son and Wataru fought against Arc in a fierce battle, destroying Arc as Kiva Emperor Form and Flight Style with assistance from Castle Doran.

Legend Arc

Through the use of the Wake Up Fuestle (which resembles Rey's Key Fuestle in the movie), Arc transforms into Legend Arc (レジェンドアーク Rejendo Āku) by assimilating the demon-eye of the moon to obtain the full power of his race, growing wings and a second set of arms. In this form,Kamen Rider Arc is able to fly. In the process, Arc Kivat assumes Mecha Kivat (メカキバット Meka Kibatto) mode as his persona cast comes off and yells "Go to Hell!"

As Legend Arc, he can open up the giant mouth/eye in his chest known as the Dead Crusher (デッドクラッシャー Deddo Kurasshā) and create the Ultima Black Hole (ウルティマブラックホール Urutima Burakku Hōru) to perform the Ultima Dead End (ウルティマデッドエンド Urutima Deddo Endo) finisher with the destructive power of 120t.
