Diaclone Machine Dragon, Dinobot killer

New here. I used to live in Japan. I bought this toy in 84 that I loved that seemed to advertise it as the enemy of the dinobots. It was this dragon that didn't really transform. It had magnetic ball socket limbs that could be interchanged with weapons, tank treads, and whatnot. Does anyone remember this toy, or know of any back-story behind it? I remember tons of other stuff that I don't really see around. I recall buying it with a Swoop that had different colors- think it was red instead of blue, and they came with the pilots with magnetic feet.
I just googled it, damn. Wish I still had all the pieces.
Think random pieces of him would be worth anything?
