Punky Brewster was an American sitcom about a girl being raised by her foster parent, Henry Warnimont, and enjoying plenty of adventures with her dog Brandon and best friends. The show ran on NBC from September 16, 1984 to September 7, 1986 and again in first-run syndication from October 30, 1987 to May 27, 1988 when Columbia Pictures Television purchased the rights to the show; a total of 88 episodes were broadcast.
Punky Brewster spawned an animated spin-off with the same-named title. The series featured the original cast voicing their respective characters and featured an exclusive critter character, Glomer. The cartoon was produced by Ruby-Spears Productions, and aired on NBC from September 14, 1985 to December 6, 1986 with 21 episodes having been made.
ThunderCats was an American animated series about a group of cat-like humanoid aliens who struggled against the forces of darkness and lived by a sacred code. The show was created by Tobin "Ted" Wolf, animated by Japanese animation studio Pacific Animation Corporation, and produced by Rankin/Bass Productions, running from 1985 to 1989 with a 130-episode total.
The series was originally distributed by Rankin/Bass' then-parent company, Telepictures Corproation, which would later merge with Lorimar Productions in 1986 to become Lorimar-Telepictures. In 1989, Lorimar was purchased by and folded into Warner Bros., which eventually assumed distribution of the show and has had the rights to it ever since.
I'm currently writing my crossover and will have it done once I've fleshed it all out.
