==Notes==
* Unlike the original Dark Kabuto, Kazuyoshi immediately pulls the Dark Kabuto Zector's horn after sliding it into his Rider belt and before the transformation begins. This causes Kazuyoshi to transform directly into Dark Kabuto's Rider Form, bypassing the armored Masked Form. It is unknown if the original Kabuto series Riders possessed this ability; the only prior instance of bypassing Masked Form was Tendo Soji transforming into Kamen Rider Kabuto's Rider Form in the noncanon Kamen Rider Kabuto Hyper Battle DVD, although Tendo did not pull the Zector's horn prior to transforming.
