Special Power: Rider Kick
Kiva Form 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. 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 made of Lucifer Metal so Kiva can use his Rider Kick the Darkness Moon Break . 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) .
