Kamen Rider Dark Kiva - Kamen Rider Dark Kiva

Kamen Rider Dark Kiva

Dark Kiva only appears to have one form, similar to that of Kiva Emperor Form in black and red. However, Dark Kiva does not require the use of a being such as Tatsulot to achieve this form, and has no chains on his body as Kiva needs to control his power. As Dark Kiva, the user has access to an unlimited potential of power that is hindered within its successor such as telekinesis and the use of the Kiva insignia as a weapon.

As Maya would later explain, the Kiva power cannot be used by a normal human, as usage would ultimately result in death. This would prove to be true, as Otoya had used the Dark Kiva power a total of three times before finally dying due to the strain it put on his body. Shima also mentioned this when Wataru revealed his heritage to him.
