Did you know, that back in the 80’s and early 90’s, all the animated shows produced to market Hasbro toys were part of an interconnected “Universe”; a single continuity? With most of the shows having been written by the same group of people (Marvel/Sunbow, for the most part), this shouldn’t come as much of a surprise.
Well, I have put-together a detailed list of every cross-over, reference, cameo and guest appearance made between Transformers, G.I. Joe, Inhumanoids, Jem & the Holograms, My Little Ponies, C.O.P.S. and the Battle Beasts.
Hopefully, you might find some of this info either informative or nostalgic, or maybe even both.
