Scrappy-Doo is a fictional Great Dane puppy created by Hanna-Barbera Productions in 1979, with the catchphrases, “Scrappy Dappy Doo”, “Lemme at ’em!” and “Puppy Power!”. He is the nephew of Hanna-Barbera cartoon star Scooby-Doo. Scrappy has appeared in a number of the various incarnations of the Scooby-Doo cartoon series. Lennie Weinrib provided his voice for one season in 1979, and from 1980 on it was performed by Don Messick (who also voiced Scooby). In the first live-action theatrical film, video games, and commercials, he was voiced by Scott Innes. He was created to save the show’s ratings which by 1979 had begun to sink to the point of cancellation threats from ABC, who were considering choosing between Scooby-Doo and an unnamed pilot from Ruby-Spears Enterprises which Mark Evanier had also written. After the 2002 live action Scooby Doo ( where Scrappy was the villain) he was never mentioned again except for a split second in Scooby doo mystery incorporated.
