Scrappy Doo was introduced in 1979 as Scooby Doo's nephew in the series Scooby Doo and Scrappy Doo, created to boost the show with a bold contrast to the cowardly Scooby and Shaggy. His catchphrases let me at em and puppy power summed up his habit of rushing villains twice his size. Decades later the line lives on in edits and soundboards, used whenever confidence wildly outweighs size or skill, keeping the character's scrappy energy alive beyond the original cartoon.
