What really amazes me is that Stinger's so 'special' that he gets to be a store exclusive character yet he doesn't even get his own mold (or figure as far as we know) in the Generations line. And that's despite actually being named in the movie, which is rare for any character who's not an Autobot. Nope.
Of course it would've helped if any of those Silver Knight figures were actually remoulded to have the different chest design shown in the packaging art. But like most of the Stinger merchandise it all seems a bit half-arsed.
After going to a walmart and seeing both mass release and exclusive version, I saw that they were exactly the same color. This means that they may be a variant where later versions used the lighter color plastic.
Stinger was probably the figure I anticipate the most from this movie but again we never get what we want.
