I finally realised what it is about him that seems off! Looking at the G1 and the grey on the body always seemed a more dark tan kind of colour, this is a full on slate grey. Of course the mouth not being yellow is a bug too but that was pretty obvious, and my FP Chromedome already has the wrong colours on his face so what's one more to the club? I might still get this guy, but I've other priorities for now.
