The titular protagonist of the Scooby-Doo franchise, Scoobert "Scooby"-Doo is a talking Great Dane that serves as Shaggy's pet and best friend, as well as the mascot of Mystery Inc.. He shares his owner's hunger and cowardice. He's also well-known for his iconic catch phrase, "Scooby-Dooby-Doo!", which he usually howls at the end of every mystery he and his gang solve.
As Scooby has only appeared in the MultiVersus x NHL Face-Off presentation so far, it's currently unclear what role, if any, he will play in the final release of the game.
