Scrappy-Doo is a Great Dane puppy and the nephew of Scooby-Doo. Scrappy is the most noteworthy of Scooby's relatives. He is noted for being quite headstrong and always wanting to face off in a fight against the various villains (unlike his uncle).
His ears are pointed and slightly bent at the tip. His coat is brown, and he has a black nose, black/brown eyes, and black spots on his back. He wears the traditional Doo family collar. In the Laff-A-Lympics he also wears an blue team shirt with a "S" on it.
Scrappy idolized his uncle Scooby and would often assist Scooby and his friends in solving mysteries. With a highly energetic and brave personality, despite his small size, Scrappy was the opposite of his uncle; Scrappy would usually insist on trying to directly fight the various monsters Scooby and his associates encountered.
