Roidmude 066 is a Low Class Bat-Type Roidmude and a minor antagonist in Kamen Rider Drive, appearing only at the start of episode 43.
During the Global Freeze, Roidmude 066 marched with his fellow Roidmudes in their revolt against humankind. He was destroyed by Kamen Rider Protodrive, but his core survived and was later restored to a body.
In the year and a half following the Global Freeze, after Gold Drive took over the Roidmudes, 066 was sent by him to find an ideal location for them to begin a second "true" Global Freeze. However, 066 was found and pursued by some Special Forces soldiers. As he was fleeing 066 attempted to stop them by trapping them in a Heavy Acceleration but a single soldier fires an anti-Roidmude bullet at him and kills him.
