Scooby Doo: Creep Combat

Scooby Doo: Creep Combat is a fighting game that uses the Scooby Doo license, released in 2002 for the PlayStation 2 and GameCube. It's set around the antagonists of the Scooby Doo universe who fight to see who's the dominant monster.

It was made as a holdover title, as Cor-Son were still working on a different Scooby Doo game Scooby Doo: The First Mystery, and was outsourced to different developers (Cor-Son did have some involvement in the character design and writing though)
