Making a placeholder thread as I'm waiting for this supplement set to come out. It adds some extra parts to be closer to the look of the original toy instead of the leaner IDW redesign, and an extra head with a different face.
Short version is that it's a beast of its own, not just a Devastator toy. Between the anticipation for such a thing (make a combiner, but BIG!), a third party company getting around to it before Has/Tak, the price tag, the QC problems and the included fixes, it's something of... a milestone for transforming toy collectibles, if there is such a thing.
