About the other imitation AOU figures, I actually got obsessed about it last week and made some research. There are actually
1112 brands that made AOU figures! It's insane! I'm not gonna post the pictures, but I'll include the links. And basically, SY & Decool are the only sets that are good. The other 9 brands are not good even on pictures.
