He-Man's faithful pet/sidekick, Battlecat, has his origin story told in this season 2 episode from October 1984. One of the hooks is that this was written by the husband & wife team of Richard & Dorothy (D. C.) Fontana. Ignore the 1985 copyrights in the closing credits.
Dorothy Fontana is better known for her writing on Star Trek, both the 1966-9 live action series, and the 1973-5 Filmation-Paramount animated version. He-Man's staff of writers also included a couple of future fan favorites in J. Michael Straczynski and Paul Dini.
