Is any of the scoobydoo characters dead?

In the official Scooby-Doo franchise, none of the main characters, including Scooby-Doo, Shaggy, Fred, Daphne, and Velma, are depicted as dead. The series is primarily a lighthearted mystery-comedy aimed at children and family audiences, focusing on solving mysteries rather than dealing with themes of death. However, in various fan theories or unofficial adaptations, characters' fates may be explored differently, but these are not part of the canon.
