* Technically, yes. Disney owns the rights to the story of Peter Pan and has made several adaptations, including the classic 1953 animated film.
* But, no, it's not exclusively a Disney creation. The original story of Peter Pan was written by J.M. Barrie in 1904 and has been adapted many times by various companies and filmmakers.
So, while Disney has a very famous and popular version of Peter Pan, it's not the only one.
