Mr. O'Greazy is a fast-food restaurant developer.

Physical appearance

Mr. O'Greazy is an obese, middle-aged Caucasian male, who has lost the hair off the top of his head, while the rest of it is brown. He has flies swarming around his head.


He takes his business involving fast food very seriously. He's not concerned with flies buzzing around him for obvious reasons. He's also shown to be very adamant about how he gets business taken care of, whether it makes him a suspect, or not.


A Pup Named Scooby-Doo

Season one

He wanted to buy the home of the Johnsons and use the land for another O'Greazy fast-food restaurant in Coolsville — one that would perhaps be easier for people to get to in the city. Because of this, he was a possible suspect to be behind the BooBeard haunting, but was found innocent when BooBeard was unmasked as Jack. It was also noted, according to Velma, that BooBeard put O'Greazy's buckets at the scene they were found for O'Greazy to be framed.[1]

He hired Grady Laurence to perform in his new Bucket O' Nachos commercial but later fired him due to secretly wanting a better actor. He later rehired him to star in a new commercial; this time, it was a new Bucket O' Scooby Snax commercial.[2]

Season two

He was haunted by the Burger Monster. He hired the gang to find the one responsible for trying to put him out of business. He then thanked the gang for a job well-done.[3]
