The Secret Files of Teletraan II were a series of short (1–2 minute) profiles which aired in 1986, after select episodes of the third season of the original Sunbow cartoon series. They included recaps of past events, character and group profiles, and "where are they now" guides, helping to explain the 20-year time gap between seasons 2 and 3 to viewers who had not seen The Transformers: The Movie.
