In the 1986 storyline of "Kamen Rider Kiva," the Fangire King assumes the form of all-powerful Kamen Rider Dark Kiva through the use of the Dark Kivat Belt and Kivat-bat II. Here's a fun electronic toy that allows kids to role-play as the supervillain with this set of an interactive Kivat-bat II, six Fuestles, and a Dark Kibuckle! Kivat-bat II can play 62 signature phrases and sounds, and his eyes will light up. Put on the belt (designed to fit waist sizes 50-68cm), simulate Kivat-bat II "biting" your hand by pressing its fangs in with your left hand to activate a transformation sound, then attach Kivat-bat II to the belt's Dark Kibuckle to complete the transformation into Kamen Rider Dark Kiva. Insert either one of the three included Seal Fuestles (Garulu, Basshaa, and Dogga) into Kivat-bat II's mouth to seal the respective Arms Monster. Other Fuestles include a Dark Wake Up Fuestle, Doran Fuestle for summoning Castle Doran, and Buroon Fuestle for summoning Buroon. The six Fuestles can be stored in the Dark Kivat Belt's six Fueslots. You can also play a game with Kivat-bat II in which he asks for a certain Fuestle in Japanese; if the correct Fuestle is inserted into his mouth, he will congratulate you. Find out what will play if you inserted all the right Fuestles! Two AAA batteries are required, not included.
