Peter is a magical, cocky boy who completely refuses to grow up and lives on the island of Neverland. He despises adults and the concept of motherhood, yet he routinely travels to the real world to listen to bedtime stories outside the Darling family's window. Though charming and eager for adventure, he is notably ignorant of basic reality and often exhibits a deep, careless cynicism.

Wendy is the eldest Darling child and a young girl with a strong sense of imagination mixed with domestic responsibility. She eagerly accepts Peter's invitation to Neverland, bringing her younger brothers along so she can act as a mother figure to the island's inhabitants. She is practical and nurturing, serving as a bridge between the fantasy of Neverland and the reality of growing up.

Captain Hook is the sinister but elegant leader of the pirates in Neverland. He maintains a strict obsession with good form and carries himself with an aristocratic, dark demeanor that separates him from his common crew. He harbors a venomous hatred for Peter Pan's cocky attitude and lives in perpetual fear of a specific crocodile that swallowed his arm.

Tinker Bell is a tiny fairy who accompanies Peter Pan on his adventures and speaks in a language that sounds like golden bells. Because of her extremely small size, she is only capable of holding one emotion at a time, making her incredibly volatile. She is fiercely possessive of Peter and exhibits extreme, dangerous jealousy toward Wendy.

The lost boys are a group of children who fell out of their perambulators as infants and were sent to Neverland when unclaimed by their parents. They live underground in hollowed-out trees and follow Peter Pan's orders. Unlike Peter, they eagerly desire the presence, rules, and affection of a mother.

Mrs. Darling is a deeply loving and attentive mother who carefully manages her household. She possesses a lingering connection to her own childhood imagination, remembering her early belief in Peter Pan and fairies. She is the first adult to discover evidence of Peter's visits when she successfully traps his shadow in the nursery window.

Mr. Darling is a practical, financially anxious man who cares for his family but frequently obsesses over maintaining strict order and balancing the budget. To save money, he employs a Newfoundland dog as a nurse rather than hiring a human. His strict adherence to rules leads him to tie the dog outside on the exact night his children fly away.

John is the middle child of the Darling family. He possesses his own unique version of Neverland in his imagination, which prominently features flamingos. He eagerly learns to fly and joins his sister on the grand adventure, bringing elements of his proper English upbringing into their fantasy games.

Michael is the youngest of the Darling children. Like his brother, he is quickly swept up in the excitement of Peter Pan's arrival and the prospect of traveling to a magical island. He relies heavily on Wendy's maternal instincts once they leave home.

Nana is a Newfoundland dog employed by the Darlings as a full-time nanny to save money. She is highly competent, watchful, and protective. She instantly recognizes the danger of Peter Pan's presence and successfully traps his shadow during his first visit, though her warnings are later ignored by Mr. Darling.

Smee is a surprisingly genial and polite member of the pirate crew. Despite his violent profession, he has a pleasant demeanor that makes him oddly well-liked by the children they capture, creating confusion for his strictly villainous captain.

Tiger Lily is the proud and brave daughter of the Indian chief in Neverland. She is an inhabitant of the island who frequently clashes with Captain Hook's pirates and maintains a distinct independence from the lost boys.

Tootles is a somewhat silly but incredibly sincere member of the lost boys. He is deeply desperate for a mother figure and is easily influenced by the chaotic environment of Neverland, leading him to make impulsive decisions based on Tinker Bell's trickery.
