At a recent Japanese convention called Superfestival, a toy of the Cloud Starscream (using the GEN Voyager Blitzwing/Doubledealer mould) was on display.
And the non-convertible items by Fewture and Unimetal were on display again as well.
The Blitzwing mould looks nice in Starscream colours, but does it "feel" like Starscream to you?
