Cosgood Creeps is a middle-aged Caucasian male with gray hair. He wears a light green suit, with black shoes, a dark green tie, and a white undershirt.
Aside from his unnerving demeanor and menacing behavior, Creeps doesn't think twice about swindling his client and his client's heirs out of a fortune.
Scooby-Doo, Where Are You!
Cosgood Creeps, along with his partner Mr. Cuthbert Crawls, were the attorneys of the late Colonel Beauregard Sanders. When Sanders' heirs, comprised of several relatives and Scooby-Doo, arrived at his house for the reading of his will, Creeps greeted them and informed the group that his colleague Mr. Crawls was unable to attend. He then revealed that Sanders' will specified that they must spend the night in his haunted mansion in order to receive their inheritance; any heir that might leave during the middle of the night would be cut out of his fortune. Creeps then left the heirs to spend the night alone in the mansion.
After all the heirs except for Scooby went missing, apparent victims of the haunted mansion's green ghosts, the gang was able to trap the ghosts and reveal that they were really Sanders' attorneys, Creeps and Crawls, who conspired to scare all the heirs away from the mansion so that they could take control of the Sanders fortune.

Brothers Sam and Dean Winchester were sucked into A Night of Fright is No Delight by a real ghost where they witnessed the beginning of Cosgood's plot, where he delivered his speech to Colonel Sanders' heirs. Dean identified Cosgood as the villain to Sam, who commented "no kidding."
In this instance, Cosgood was killed by the real ghost who took on the form of one of the fake Green Ghosts. After being captured by the Winchesters with the help of the Scooby Gang, the ghost took on Cosgood's form and allowed himself to be "unmasked" to trick the Scooby Gang into restoring their wholesome mindset.
