The Mascot Menace was the disguise of Dean Richard, the administrator of an unnamed university.

Physical appearance

It looked like a purple stingray with set of sharp, yellow teeth. It had vertical cat-like eyes and green sclera.


It treated Scooby-Doo and Shaggy Rogers like prey, while making dolphin-like sounds.

Powers and abilities

  • Flight: It could soar in the air by using its fins as wings, but how Dean Richard actually achieved that is unknown.

The university had a track meet for candidates in the World Invitational Games, which Shaggy Rogers and Scooby-Doo ran past as they were being chased by the Mascot Menace. Fred Jones was able to catch it with a net gun, allowing the police to hold him still and Velma Dinkley to unmask him. His intentions were left unrevealed, mostly because the attention was still on Shaggy and Scooby still running.
