J.M. Barrie's works containing Peter Pan are no longer under copyright protection. Works created and published before 1928 had a shorter copyright life than works created today.
Peter Pan works that have come from Disney are under copyright protection. To the extent that Disney contributions have modified elements of Peter Pan or the story, they own copyrights in those modifications. If you create a Peter Pan anything, you will garner the interest of Disney and I expect they will look to see what if any elements of their contributions have been taken by you, giving them grounds for an action.
I would also look into any trademarks Disney may own relating to Peter Pan and, particularly, video games.
