Wendy is an adventurous 12-year-old girl, who loves to dream and tell stories to her younger siblings. Though her imagination is vivid and praised by her brothers Michael and John, Wendy's storytelling was initially looked down upon by her father, George, who found Wendy's stories and childlike nature to be immature and ridiculous, and voiced his desire to have her abandon her childhood as soon as possible to prepare herself for eventual adulthood. Because of this, Wendy grew a fear of growing up, and found comfort in the stories of Peter Pan and Never Land.
Nevertheless, upon visiting Never Land for the first time, Wendy found her maturity growing and becoming a more prominent part of her character as the overly adventurous and somewhat eccentric events on the fantasy island took place. This led her to finally accepting the fact that she will inevitably become an adult, one day. Even so, the young girl didn't allow this revelation to destroy her wondrous imagination.
As an adult (seen in Return to Never Land) Wendy hasn't lost her belief in Peter Pan, and tells stories about him to her two children, Jane and Danny. She has grown into a caring, smart, kind, and beautiful woman.
