The Open Roidmude, originally designated as Roidmude 067, is a Fusion Advanced Roidmude and an antagonist in Kamen Rider Drive.
He was voiced by Yoshimasa Kawata.
With a Cobra Neo-Viral Core, Roidmude 067 synchronized himself with Itsuro Negishi, a criminal involved with a robbery in 2003, to become the Open Roidmude. The Open Roidmude was sent by the Brain Roidmude to kill anyone associated with the robbery. After killing three bank workers, Open attempted robbery at another bank in order to kill Tomoko Sannomaru. However, Kamen Rider Drive appeared to stop the robbery and forced Open to retreat. Itsuro later attempted to kill his former accomplice Maruya, but Kiriko, Drive and Chase stopped him.
The Open Roidmude's next move was to go after Yukari Karasawa, a young girl whom Eisuke Tomari had protected 12 years ago. Open headed towards hospital she was at, but Shinnosuke got there first to take her to a safe haven. As they exit the hospital, Open attempts to attack Yukari but Shinnosuke shields her, causing her to remember what happened 12 years ago. Kamen Rider Chaser soon appears to assist Drive and the two Riders perform their Full Throttle finishers which separate Itsuro from 067 and kills 067. Shinnosuke interrogates Negishi about the robbery incident, but discovers that he had his memory wiped by Freeze.
