|This article is about a/an rider in Kamen Rider Decade.|
Kazuyoshi Aoyagi (青柳 和良 Aoyagi Kazuyoshi) is an old friend of Natsumi and a founding member of Club TG. His counterpart of Nega World was killed by the Dark Riders and supplanted by Dark Kabuto.
Under orders from Otoya, Kazuyoshi/Dark Kabuto and his partners tricked Natsumi to meet her Nega world counterpart and lead them to his treasure the K-Touch. He dies battling Decade in his Complete Form, using the power of Kabuto Hyper Form's Hyper Kick to clash against Aoyagi's own.

This alternate version of Dark Kabuto has only one form, which is the sleeker and more offensive-based Rider Form (ライダーフォーム Raidā Fōmu) which closely resembles the Japanese rhinoceros beetle on which Dark Kabuto is named after and themed. It is in this form that Dark Kabuto has access to the Clock Up (クロックアップ Kurokku Appu) command which allows Dark Kabuto to travel at near-light speeds to match the speeds of the Worms. By pressing three buttons on the belt in succession, Dark Kabuto can perform his tachyon-powered Rider Kick called the Dark Rider Kick (ダークライダーキック Dāku Raidā Kikku), a roundhouse kick from a standing position.

- 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.
