When I was a kid, there was Voltron.
My brother and I loved it, but we loved the toys more. Like this one:
That guy actually came apart and the lions were their own separate creatures (yes, I remember that from the cartoon itself). Incidentally, I don't remember much more about the show itself. Blasphemous, no?! But I do know we watched the show religiously, and had the toys.
Of course, I wound up using the lions in other games, namely as Barbie's "pets".
I hear it's being made into a movie!? I don't even know if it has happened yet. That's how "up" I am on my childhood favourites and their current status in society. Of course, if there was a Jem and the Holograms movie rumour, I'd be scouring the internet for more information!
