Dr. Roscoff is a retired chemist.
He is bald with gray hair on the sides, and he wears glasses.
He has a great deal of selfishness and cruelty to enslave the town as he did.
He realized he could operate the old gold mines near Oroville with slave labor, by drugging the water supply and using a hypnotic machine to draw people out at night to work the mines for him. He also painted his dog Fang with luminous paint to be the Phantom Wolf to keep interlopers away.
