He is the pet and life long companion 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 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.
His current voice is Frank Welker (2002-present).
