Neither are definitive answers, though. Whoever has the deepest pockets will continue to fight if they think it's worthwhile, particularly if they believe their products and trademarks are being brought into disrepute.

The BBC, while being relatively free and easy with fan art, take a very strong dislike to anyone using their stuff for political, satirical and commercial purposes. They had several ads, tv shows and various other things pulled which featured Daleks, when they were used without permission. You probably already know that Disney are notorious when it comes to protecting their intellectual property, whether used for commercial gain, fan art or just for fun.

Disney would lose in court if it's a parody or satirical work in the US and they know this. So they usually just try to intimidate people with long drawn out court processes that they know most people can't afford. So Disney gets their way.
