Shaggy Rogers
Norville "Shaggy" Rogers is a member of Mystery Incorporated and the owner and best friend of their team's mascot: Scooby-Doo, a talking Great Dane and the main character and the protagonist of the Scooby-Doo franchise.
Shaggy Rogers first appeared in the Scooby-Doo, Where Are You! episode "What a Night for a Knight" in 1969, and 24 other episodes in the series. He has since gone onto to appear in countless spin-off TV series, specials, films, comics, and video games.
The voice was originated by Casey Kasem.
Throughout the years, Hanna-Barbera, Cartoon Network, and Warner Bros. Animation, as well as book and video game publishers, have conceived several incarnations, which don't always fit together because new writers have come on board and disregarded what has come before or there has been a complete reboot, but the general concept has been the same, perhaps except for DC Comics' radically altered Scooby Apocalypse.
