>>6835802Problem of getting permission aside, Spawn has some recognition in Japan but not enough for current Kaiyodo to risk it, Not at the price range it'll be at.The most adventurous AY has been so far was Spider-Gwen, maybe Carnage too. That should tell you the line AY will not likely cross for popularity level of their character selection. AY is made for Japan with Western markets in mind, but it's not tailored to please the Western one, only a sale boost to keep afloat.
If you want to talk about non-Marvel & DC properties, well-known everywhere, could use Yamaguchi articulation, and as a bonus done by Kaiyodo before so easier access, I'm going for TMNT. IDW version? I'm not familiar with it, not sure if you can cut cost with shared sculpt. The recent cartoon version was probably successful enough, got that rerelease after all. There's that dilemma of it's cheaper just to rerelease again than to make new ones, but the more realistic musculature look of AY versions plus the incredible posing ability would make it worth the cost. They'll make Shredder then because AY makes villains, and that'll be a huge victory for Revoltechs.
