- "Wake Up!"
- ―Kivat's finisher announcement[src]
The Demon Imperial Sword Zanvat Sword (魔皇剣ザンバットソード Maōken Zanbatto Sōdo) was a sword of great power crafted and used by the previous King until he tossed the weapon into Castle Doran's wall. By 2008, after sensing the power of Wataru as he evokes Kiva's Flight Style, the sword forced itself out of Castle Doran's walls. It then resisted being pulled by others until Wataru pulled it out by seeking more power.
The Zanvat Sword is soon after modified with a living hilt named Zanvat-bat (ザンバットバット Zanbattobatto), called "Zanvat" for short, who was created from the Life Energies of the Arms Monsters to control the unstable powers of the blade from evoking Wataru's Fangire blood. Though Wataru is accepted as an ideal user, he has yet to fully master the Zanvat Sword's true power.When used by Kiva in Emperor form, its finishing attack is the Final Zanvat Slash (ファイナルザンバット斬 Fainaru Zanbatto Zan) where Kiva's power is focused into the Imperial Blade (インペリアルブレード Inperiaru Burēdo). The attack is powerful enough to destroy giant monsters such as Sabbats and even a Mother Sagarc.
Kamen Rider Decade
Kiva was seen using Zanvat Sword in the first scene of the Rider War in Kiva Form. During episode 30, the A.R. Kiva uses the Zanvat Sword to perform the Final Zanvat Slash along with Thorn Fangire in order to kill the A.R. Leangle.
Let's Go Kamen Rider
It is shown in OOO, Den-O, All Riders: Let's Go Kamen Rider that Kiva can use the Zanvat Sword without transforming into Emperor form, but cannot use the Wake Up finisher though the situation was different with his A.R. counterpart.
