I have no idea, but it looks really cool, and judging the packaging alone, it looks like a domestic release, but you'd think we would have heard about it by now... I really like it, and the packaging is really nice, hopefully someone can shed some more light on it. EDIT: Of course, it could be some kind of unofficial release, also. hmm...
These days, probably due to the popularity of TFs right now, there's been a lot of creative KO figures done. Even some that look like entirely new molds. This is just another one of those, and is most certainly not a Hasbro product.
Even if it's a KO, it's really COOL that the bootleggers made a new mold. I don't know about the materials used, but the complexity is at least on par with a Fast Action Battler.
It looks like the chest of a Voyager Prime/leader Prime with the rest being a FAB k.o. still cool none the less. And it's different enough to be a Motormaster repaint.
