Professor Moliarty is a recurring villain from Darkwing Duck. He is a mole who, along with the others of his kind, lives beneath the surface, because the sun is very harsh with their eyes and skin. He is bent on conquering the surface world, making it a good place for the moles to live, which involves blocking the sun and wiping out all the inhabitants of the surface.

Moliarty is very arrogant and coward, manipulating others to further his goals and endangering them to take himself away from danger, even his fellow moles. His name is a obvious reference to Professor Moriarty from Sherlock Holmes.
