Here's a short list of mine:
Transformers (pre-movie)
GI Joe (pre-movie)
Thundercats (pre-other cats' arrival)
Silverhawks
He-Man (pre-She-Ra)
Smurfs (pre-Johan/Peewit)
Voltron
Inspector Gadget (had to be in the mood for that one)
SuperFriends (really 1970's, but it was still around in some form)
Gilligan's Planet (d'oh!)
