Jeff Schemerman

He is the leader of the First Division of the police. He likes to bully his workers, however he never gets away with it most of the time. He first appeared in Episode 25 of Masked Driver, thought to be an anti-hero. He was working with 2 Cardroids, Cardroid 001, who was disguised as an official named C. Krett. The other one he was working with was Toxinax, who was disguised as a profiler named Dr. Brian. Later he joined the Special Police Division to take down Cardroid 001 when he evolved into Frostbiter, but was revealed to have killed Joe Johnson's father, John Johnson.

Then he used a Fusion Bat Core with Cardroid 106 to become Masked Fusion Thief. Masked Fusion Thief stole the only piece of evidence they had against him and framed Joe Johnson in Episode 35. Later, he fused with Toxinax, so Toxinax could reach Ultimate Power. However, he was arrested in the end.
