Scooby-Doo! Mystery Incorporated
Mystery Inc. went to Grady when they needed a new engine for the Mystery Machine's stolen one. He told them it would take the night to get a replacement delivered from Crystal Cove and they could apend teh night at his family's hotel.
Like the rest of his family, he took part in the creation of counterfeit alligator products, and dressed up as one of the Creeping Creatures to scare people away. When exposed by Mystery Inc., Grady alongside Greta and Gunther were arrested by Sheriff Bronson Stone and his men even though Crystal Cove's police force had no jurisdiction in Gatorsburg. (The Creeping Creatures)
Grady Gator later made a cameo in the local prison where he was seen in line at the cafeteria. When Grady asks Shaggy and Scooby-Doo what they are in prison for, Shaggy states that they are here for the food. (Wrath of the Krampus)
