>>6600045Sorry for the improvised picture.
As anons have already pointed out, WoN doesn't really have an internal scale. But when it comes to Mario figures I think WoN and SHF line up really well. The WoN enemies tend to be a bit bigger on the whole as has been pointed out, but that works pretty well for me.
I don't actually own either Bowser so I can't show you the size comparison, but WoN Bowser is significantly larger (albeit less articulated).
