>>8404536>I ended up buying the later ones too but the proportions arent as SDTurns out the later ones weren't even from the same line. They were actually repurposed from Digimon's version of Heroclix which is why they look so bland, and the SD figures were from a line that tied in with the release of the original V-Pets.
The American versions (left) are easier to find but unfortunately they're missing a lot of detailing, and almost look like bootlegs compared to the originals (right).
To add to the confusion, there's also actual bootleg versions floating around auction sites.
