Scooby-Doo

Scooby-Doo is a long-running American media franchise that has existed since 1969, beginning with the Hanna-Barbera cartoon series Scooby-Doo, Where Are You!. The format, cast and artistic style of the franchise has been altered dramatically over the years; however most - if not all - of the shows contain the protagonist, a Great Dane named Scoobert "Scooby" Doo, and an array of human characters, prominently Scooby's best friend Norville "Shaggy" Rodgers. The show contains a number of anthropomorphic animals, primarily dogs.

Main characters

 * Scooby-Doo is a brown Great Dane with black spots and a large appetite, particularly for Scooby Snacks. He can talk, however can have difficulty speaking and usually begins words with an "R" sound. Scooby primarily walks on all-fours (a quadruped) however has shown the ability to walk upright with ease (a biped).
 * Scrappy-Doo, Scooby-Doo's younger nephew, is a headstrong puppy who regularly wants to engage the villains they encounter in a fight, only to be pulled away by his uncle and Shaggy. Unlike Scooby, Scrappy can talk without hindrance. Although initially popular, he has since become one of the most hated characters in any popular culture work; TV Tropes even named a trope after him, The Scrappy, due to the significant amount of hatred he received.
 * Scooby-Dum is a grey Great Dane and cousin to Scooby-Doo. He is dim-witted dog who longs to be a detective.
