>>5307693Ainz would be difficult. But I could honestly settle for him if he just had some basic torso movement, arm articulation, and a neck joint.
I actually think Papi would be the most difficult simply because she would need swappable wings. Revo has already done fine segmented long bodies with their dragon thing. Rachnee wouldn't be too difficult either and figma has already done a mermaid and a horse. Suu's only difficulty would be whether or not to make her semi-transparent. They'd be expensive, but with things like the figma horse and tank it's not that out there.
