>>11023385NTA, but 1/12 is really not different enough from 1/18 for what you get on average, especially from Hasbro. As reluctant as they are, you can get most of the same joints in there. This is from around 2007. Sculpt proportions are a bit scrawny, but you get even butterfly joints in this, hands are swappable so you can get ones with ulnar/radial wrists(for sword pointing). Only other possible upgrades here would be mid-calf swivels, better hip design, and toe-bend
Over the decade and a half since, face detail has made huge leaps and bounds for both 1/18 and 1/12, but they're still about the same level on average.
I would say that 1/12 has more opportunity if they do things like ab crunch/knee-to-chest movements or more expressive neck movements, but those types of figures aren't the norm
