While Tinker Bell has appeared in other Disney films, she's never been the central character in a theatrical release. She has had cameos in films like:
* Peter Pan (1953): This is where she originated and is probably her most well-known appearance.
* Return to Neverland (2002): A more recent film that takes a different approach to the Peter Pan story.
* The Pirate Fairy (2014): A Disney Fairies film that features a younger Tinker Bell and focuses on her origin story.
It's possible that Tinker Bell might someday appear in a theatrical Disney animated feature, but for now, her main focus is the "Disney Fairies" franchise.
