Roidmude 027 is a Spider-Type Roidmude who attempted to sell counterfeiter Televi-Kun issues before he is found by Shinnosuke and Kiriko. During the fight, Roidmude 027 gathers enough data on Shinnosuke to become a counterfeit version of Kamen Rider Drive as his replication of Drive's arsenal gradually improves. However, Roidmude 027 is forced back to his original form and destroyed by Drive in his High Speed form.
Eisuke Tomari is Shinnosuke's father who was a cop in the Metropolitan Police's First Investigation Division. He discovered Makage's identity as Freeze 12 years earlier and confronted him to find out the truth, being immune to Roidmude 001's memory altering abilities. Eisuke ends up being killed by Nira while the two attempted to arrest a bank robber whom Nira framed for Eisuke's murder.
