Isis
The Secrets of Isis is the syndicated title of a live action CBS television series produced by Filmation in the 1970s originally titled Isis that appeared during the Saturday morning cartoon lineup. The show was also aired in various countries around the world. As indicated on commentary in the 2007 DVD release of the series, and supported by examining broadcast premiere dates, The Secrets of Isis was the first weekly American live-action television series whose lead character was a female superhero, debuting September 6, 1975 and predating the weekly debuts of both The Bionic Woman and Wonder Woman.
Originally broadcast as Isis, this 1975 CBS Filmation live-action series comprises 22 episodes across two seasons. It shares crossover appearances with Shazam! (1974), while retaining separate episode coverage. John Davey appears as Captain Marvel, the character now known as Shazam. The complete-series DVD's Freedom Force episode The Plant Soldiers is separate animated bonus content. Andrea Thomas/Isis and supporting official DC profile matches, complete appearance coverage and exact episode durations remain unresolved.
