Jazwares, the guys who have made quite a few Sonic action figures as of late such as the Werehog and pose-able figures, are later this year (apparently September, but you never know with these things) releasing this rather ace looking pose-able Metal Sonic.
It's the old Sonic CD Metal Sonic too, not that rubbish thing in Sonic Heroes they called Metal Sonic. The guy seems to be making quite the come back as of late, also showing up in the new Mario & Sonic Olympics games, and of course there was that smaller mighty mugg style figure of him from Comic Con too not long ago.
