I disagree, scooby and shaggy are the main characters, it's a mainly comedy show. Fred and Daphne are basically there as filler although they have some funny quirks (eg fred's plans that never work). This includes how Daphne always gets kidnapped. This is comedic. Velma is there so that the mystery actually ends up getting solved. Velma should not be with shaggy. This and the series where he becomes rich is totally loving non-canon.
