The 13 Ghosts of Scooby-Doo

The 13 Ghosts of Scooby-Doo is the seventh incarnation of the Hanna-Barbera Saturday morning cartoon Scooby-Doo, and the final first-run version of the original 1969–1985 broadcast run of the series. It premiered on September 7, 1985 and ran for one season on ABC as a half-hour program. Thirteen episodes of the show were made in 1985. It replaced Scary Scooby Funnies, a repackaging of earlier shows; another repackaged series, Scooby's Mystery Funhouse, followed. The series also aired in reruns on USA Network in the 1990s, on Cartoon Network, and from time to time on Cartoon Network's sister channel Boomerang until 2014. With 13 episodes, it is the shortest-running series in the Scooby-Doo franchise. A follow-up film, ''Scooby-Doo! and the Curse of the 13th Ghost'', released in 2019, featured the previously unseen 13th ghost. The entire series is also available on the Boomerang streaming service.
