>>7748441That's the point of his character though. not to mention being a parody of Anpanman in name and visuals, Simple designs are more fun to pose around and Saitama can be in so many different scenarios. Day to day life to fighting just about anything. I agree with other anon about your imagination. I think he'd be a good AY as long as they go easy on the cape (fewer pieces or switch between still and dynamic).
Also I'm curious why nobody made Anpanman action figures that's more than 5poa. Sure it's for kids but it existed long enough that older people could buy something more complex out of nostalgia.
