Mine was original G1 Scorponok. You could probably also throw in Metro and Fort Max but you can get them as Encores that only left Scorponok. I never though I would get him at a) a reasonable price ($200) and b) as complete as he was (only missing 1 repair arm and 1 of Fast Tracks guns). It was a great day when I snagged that one.
Ps. I ended up finding a sweet original Metro as well only missing Scamper for a cheap price too
