An A.R. World version of Kivat-bat the 2nd (キバットバットⅡ世 Kibattobatto Nisei) appeared in Nega World. Unlike the original, is quieter and only appears when Otoya is going to change to Dark Kiva. Neither spoke much, but this is because his voice actor did not reprise his role and only use the sound effect "Gaburi" when it appeared. His partner in this world is Negative Otoya.
A version of Kivat-bat the 2nd presumably exists in the World of Kiva as well, as it has been shown to have its own version of Kivat-bat the 3rd, which like the original, is used by Wataru to transform into Kiva.
