Scoobert "Scooby" Doobert Doo also known as Scooby-Doo is the main protagonist of the popular Hanna-Barbera franchise of the same name. He is the pet of Shaggy Rogers and his three school friends Fred Jones, Daphne Blake, and Velma Dinkley in many iterations, including the original series, is regarded as a unique, strong, and very large Great Dane dog who is able to speak in broken English, unlike most other dogs in his reality, and usually puts the letter R in front of words spoken. Other incarnations, such as A Pup Named Scooby-Doo, present talking dogs like Scooby as quite common.
He is voiced by the late Don Messick (1969-1994), Scott Innes (1998-2020), and currently Frank Welker (2002–present).
