Well, You probably already know this but the cartoon series had four teenagers. Fred, Daphne, Velma and Norville, also known as Shaggy. Scoob Doo was actully the talking Great Dane
Probably Shaggy, but I like Velma and Scooby too.
I love Scooby Doo and the gang!  They crack me up! Yeah, did you know that this animated cartoon began being produced in 1969 and is still produced to this day? I didn't know it was that old. What else can you tell me?
This Saturday-morning cartoon series featured four teenagers—Fred Jones, Daphne Blake, Velma Dinkley, and Norville ''Shaggy'' Rogers—and their talking brown Great Dane named Scooby-Doo, who solve mysteries involving supposedly supernatural creatures through a series of antics and missteps.
