Goodwin Willoughby

Goodwin Willoughby is an old friend of Summer and a founding member of Club Drop Out. His counterpart of Dark Rider World was killed by the Dark Riders and supplanted by Shadowborg.

History
Under orders from Bram, Goodwin/Shadowborg and his partners tricked Summer to meet her Dark Rider world counterpart and lead them to his treasure the K-Touch. He dies battling Chrono Warrior in his Complete Form, using the power of Beetleborg Hyper Form's Hyper Kick to clash against Willoughby's own.

Kamen Rider Shadowborg
Ability Perimeters Shadowborg's Rider Form is the sleeker & more offensive-based form which more resembles the Japanese rhinoceros beetle on which Shadowborg is named after & themed. It is in this form that Shadowborg has access to the Clock Up command which allows Shadowborg to travel at near-light speeds to match the speeds of the Worms. By pressing three buttons on the belt in succession, Shadowborg can perform his tachyon-powered Rider Kick called the Dark Rider Kick, a roundhouse kick from a standing position.
