Which 1998 direct-to-video film featured real zombies for the first time?

The 1998 direct-to-video film that featured real zombies for the first time was *Scooby-Doo on Zombie Island*.

Released on September 22, 1998, the film reunited Fred, Daphne, Velma, Shaggy, and Scooby after a year-long break from solving mysteries. They travel to Moonscar Island, a Louisiana bayou location haunted by the ghost of the pirate Morgan Moonscar.

The movie deliberately overturned the classic Scooby-Doo formula. Instead of revealing every monster as a criminal in a costume, it presented genuine zombies and supernatural werecats. The zombies are former victims of the werecats’ curse, while the werecats use the island’s legends to lure new victims.

A common mix-up is saying the film was the first Scooby-Doo story ever to include anything supernatural. Earlier productions, including *The 13 Ghosts of Scooby-Doo*, had real supernatural beings. *Zombie Island* is chiefly remembered as the first major feature to make real monsters central to its story, and its darker tone helped launch the popular direct-to-video film series.
