It's beautiful how there are people in this forum that say to others not to flame a theory right from the start, and yet it happens so easily anyway no matter how much they try to persuade the flamers to forget their ways. LOL. But anyway, it is a somewhat ridiculous theory, but technically you have as little proof to say Sora isn't a prince as he does to say Sora is one. And then there are all the coincidences, such as Sora wearing the crown(but then again for some reason we don't see him wear it in the flashbacks,meaning he gained it after that...). But then it could mean he is Mickey's servant/apprentice. It could be a few things. But all you can do is speculate, so that doesn't help.
