|This article is about a/an transformation belt in Kamen Rider Kiva.|
The Kivat Belt (キバットベルト Kibatto Beruto) is Wataru's means of transforming into Kiva. To summon and use the belt, Kivat-bat the 3rd says "Let's go Kiva!" (キバっていくぜ！ Kiba tte ikuze!) as Wataru catches him in his right hand and then Kivat bites Wataru's free hand, causing his Fangire nature to surface as the belt materializes out of several ghostly chains. Wataru then perches Kivat upside down on the Power Roost (パワールースト Pawā Rūsuto) of the belt's Kibuckle (キバックル Kibakkuru) to complete the transformation, separating from the belt when certain conditions demand for it like Fuestle-blowing or attacking the Fangire on his own. The Kivat Belt also has six Fueslots (フエッスロット Fuessurotto) to hold the six Fuestles.
- The Kivat Belt is also donned by Kaori Nagura of Kamen Rider Girls, who represents Kiva in the group.
- Till date, the Kivat Belt is the last Transformation Belt belonging to a Main Rider to not be called “Driver”, a name which became standard for all Main Riders’ Transformation Belts since Kamen Rider Decade’s Decadriver.
