This alternate version of Dark Kabuto has only one form, which is the sleeker and more offensive-based Rider Form 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 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, a roundhouse kick from a standing position.
