On what TV network did Scooby-Doo first air?
Scooby-Doo
The role of each character was strongly defined in the series: Fred is the leader and the determined detective, Velma is the intelligent analyst, Daphne is danger-prone, Shaggy is a coward more motivated by hunger than any desire to solve mysteries, and Scooby is similar to Shaggy, save for a Bob Hope-inspired tendency towards temporary bravery.[9] Later versions of the show would make slight changes to the characters' established roles, most notably in the character of Daphne, shown in 1990s and 2000s Scooby-Doo productions as knowing many forms of karate and having the ability to defend herself, and less of a tendency towards getting kidnapped.
