* Peter Pan: He's the classic example. He's explicitly stated to never grow up and remains a boy forever.
* The Little Mermaid: While not technically stated, Ariel remains a young mermaid despite her interactions with the human world, suggesting she doesn't age in the same way humans do.
* Tinkerbell: Another character from Peter Pan, she's often portrayed as perpetually young and whimsical.
* The Cheshire Cat: In Alice in Wonderland, the Cheshire Cat's age is never addressed, but its ability to vanish and reappear suggests a being that transcends time.
* Many mythical creatures: Fairies, elves, and other magical beings are often portrayed as ageless or with long lifespans beyond human comprehension.
Ultimately, the answer depends on how you define "never aged" and what story you're considering. Do you have a specific story in mind?
