Scrappy (Dappy) Doo is a fictional Great Dane puppy created by Hanna-Barbera Productions in 1979, with the famous catchphrases, "Let me 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 voiced Scooby). In the first live action theatrical movie, video games, and commercials, he was voiced by Scott Innes. Scrappy initially became a breakout character for the series, but later was credited for the show's decline.
