It's my understanding that a lot of branded material(like "sonic the hedgehog") was filtered out of training data so that the copyright challenges were limited to small holders that can't fight back instead of large holders like Sega and Disney. So any prompts expecting copyright characters is going to end up wierd because of lack of training data.
