What is the title of the first episode of 'Scooby-Doo, Where Are You!'?

The first episode of “Scooby-Doo, Where Are You!” is titled “What a Night for a Knight.”

The episode premiered on CBS on September 13, 1969, introducing the core Mystery Inc. team: Scooby-Doo, Shaggy Rogers, Fred Jones, Daphne Blake, and Velma Dinkley. Its story begins when Scooby and Shaggy discover a suit of armor in an abandoned vehicle and help deliver it to a museum.

The apparent villain is the Black Knight, whose armor seems to come alive under the light of a full moon. As in many early Scooby-Doo mysteries, the supernatural explanation is eventually replaced by an ordinary criminal plot. The episode establishes the series’ enduring formula of eerie settings, comic fear, clue gathering, and an unmasking.

A common mix-up is confusing the episode title with the Black Knight character or with another first-season title such as “A Clue for Scooby-Doo.” “The Ghost of the Black Knight” and “Mystery of the Black Knight” describe the premise but are not the canonical title. The series produced 17 episodes in its first season and 41 across its original run.
