It seems that in the G1 cartoons, Megatron never knew about Optimus Primes Matrix. It seems that till the 1986 movie came out, nobody knew about the Matrix. Then in season's three and four Galvatron was after Primes Matrix? Did I miss something in G1's season 1-2? Did Megatron ever knew about the Matrix? Or was it just never mentioned that he did know? Also, is there such a thing as a Decepticon matrix?
