Mr. Clopper disguised himself as the Cockroach Monster to increase his exterminator business.

Physical appearance[]

Mr. Clopper is an adult man with balding, dark brown hair and a large handlebar mustache. He is only seen with his head protruding from the Cockroach Monster costume after he’s unmasked.

Personality[]

He seemed pretty ashamed after getting caught, but it was shown he was eager to get more business if he pretended a sewer underneath a factory was being terrorized by a giant cockroach creature.

The costume seemed to give the man a sense of confidence since he acted much more aggressive and hostile as the monster compared to his more timid demeanor after his mask was off. He was also implied to be a relatively competent actor as he was able to convincingly portray the monster’s screeches and facial expressions from beneath the mask as well as emulate the precise movements of an actual cockroach.

History[]

Scooby-Doo! Music of the Vampire[]

After Velma Dinkley defeated the Cockroach Monster, she swiped off the mask revealing Mr. Clopper, then explained his plan.
