The Boy Who Never Grew Up and titular character. Peter Pan is a mischievous, unaging boy who lives in Neverland and can fly thanks to a combo of fairy dust and happy thoughts. While often an egotistical, arrogant and childish person, Peter is very considerate and loyal to his friends.
Ambiguous Innocence: Peter is quite cruel for being a child, laughing as John and Michael Darling nearly fell to their deaths, told Wendy her mother abandoned her, and what he did to Captain Hook.
Growing Up Sucks: Peter vowed to never grow up when as a baby he overheard his parents planning his future despite only being just born, and fled to Kensington Garden where he met Tinker Bell, learned how to fly and went to Neverland.
He actually grows up in Hook and forgets his past life until later.
Fisher King: To Neverland. The island reflects his mood and sleeps when he does or when he leaves.
Hates Being Touched: In one revision of the play, and thus in some adaptations. (Barrie wrote this particular version for an actress whose interpretation of Peter heavily implied him to have been Dead All Along; the idea is that he instinctively avoids being touched to prevent everyone from finding out that he can't be touched.)
Honor Before Reason: Though he's almost completely lacking in empathy in some adaptions, he has always had a very strong sense of fairness and justice — so strong, in fact that he refuses to cheat or go back on his word on anything, even when keeping to these principles are a distinct hinder for him or might even directly lead to his death. What's more, he never really learns that other people do not have the same strict moral principles, because learning such things would be the same as maturing, which would be the same as growing up.
Living Shadow: Averted in the original novel and play, where Peter's detached shadow is never mentioned to be alive or moving on its own accord. Most of the visual adaptations, though, do portray Peter's shadow as alive and able to live separately from Peter — probably because this is much more visually exciting than a shadow that just hangs in someone's grip like a piece of laundry.
Wendy Moira Angela Darling becomes Peter's companion. An enthusiast on telling the stories of Peter Pan, Wendy idolises the flying boy and accompanies him to Neverland with her brothers but must learn she has to come of age sooner or later. She later grows up and has a daughter named Jane.
Action Girl: In the 2003 film, in which she wields a sword.
The Big Bad of the novel and all of its adaptations. One of the greatest pirates in history, Captain Hook's right hand (left hand in most of the adaptations) was chopped off by Peter and fed to a crocodile who now has a taste for Hook. He has a personal grudge to settle with Peter because of this.
Acting for Two: A common trait of Peter Pan is that actors play both Captain Hook and Mr. Darling in the same performance.
Impossibly Cool Clothes: Captain Hook is always dressed in his best clothes. Except for in Peter Pan in Scarlet, where his best clothes all got ravelled and half-dissolved along with Hook himself after the stay in the crocodile's stomach that turned him into Ravello the Ravelling Man — and so, when he returns to his old self at the end of the novel and is Hook again, he has to make due with what is repeatedly stated to be his second best clothes. It's still noted that they look good on him, though.
Noble Demon: The narrator stresses that he is "not entirely unheroic".
Not Quite Dead: In Peter Pan in Scarlet, it's revealed that Captain Hook survived being eaten by the crocodile and eventually managed to escape — but his stay in a crocodile's stomach had changed him beyond recognition, and he became Ravello the circus man.
Word of God says that "Hook was not his true name. To reveal who he really was would even at this date set the country in a blaze."
Additional details have Hook as having attended Eton College. Barrie gave a speech at the college in 1927 where he gave more of Hook's background: one story had it Hook once sat on a wall meant for the privilege of Eton graduates. When a guard confronted him about it, rather than admit he was a student - and shame the school in the process - Hook nobly hopped off to retain the school's honor.
We also know Hook once served as boatswain to Blackbeard, and was the only pirate that Long John Silver ever feared.
The novel Peter and the Starcatchers (currently being adapted to film by Disney) posits that Hook was originally known as Captain Black Stache, after his black mustache.
The Pirate Fairy presents him as a young cabin boy, and with his friendship with the fairy Zarina, presents him as a Shadow Archetype to Peter... at least until it's revealed that not only is he the true captain of the ship, he was only using Zarina for her pixie dust.
Wicked Cultured: An evil, bloodthirsty pirate he may be, but he's also a refined, well-schooled gentleman who places a huge value on "good form."
Minion with an F in Evil: While there's no doubt he could kill the Lost Boys if he wanted and slaps them around, none of them can actually take him seriously as a threat and find him lovable. Since Smee wants to be a real villain, Hook actually considers it "too cruel" to tell him what children really think of him.
Ooh, Me Accent's Slipping: In the original Disney movie, his voice actor Bill Thompson occasionally tries to pronounce the odd word with an Irish accent. It's not exactly convincing, so it's hardly surprising that Jeff Bennett, who voices Smee in modern Disney productions (including Return to Neverland), completely drops this and makes Smee an all-out American.
And in the Disney Animated version she gets terribly damaged trying to remove the exploding time bomb that was intended for Peter. Though his hideout is ruined by the explosion, both survive as he searches for the frail, weak Tinker Bell.
Killed Off for Real: Turns out she died sometime before Peter came to take Wendy back for "spring cleaning" a year after their first adventure, and Peter does not even remember her.
In Peter Pan in Scarlet, which takes place twenty years later, she is resurrected by the wish of the new fairy, Fireflyer, who's been told about her by Wendy and the Lost Boys. At the end of the novel, they're married, have set up a lucrative business selling dreams to pirates, and are so happy they're determined not to get killed for at least a hundred more years.
The Unintelligible: She speaks in a voice that to human ears sounds like tinkling bells. The audience generally does not understand her, but Peter does. In the book, the Lost Boys do as well, and towards the end, Wendy has at least learned enough of the language to recognize the insults Tink hurls at her.
How adaptations treat this varies a lot: Several adaptations, including the Disney movie, make Peter the only one who can understand her perfectly, and with everyone else she has to resort to miming to get her point across. In other adaptations, such as the World Masterpiece Theaterversion, Peter Pan & the Pirates, and Hook, she speaks normally.
Yandere: Sweet cute Tinker Bell... tries to have Wendy killed twice out of jealousy.
The Lost Boys
Peter's trusty gang; boys who were lost or abandoned by their parents and eventually ended up in Never Land. There are a lot of them over the years, and different adaptations and sequels have different Lost Boys — but the original, and most commonly-used ones, are Tootles, Slightly, Curly, Nibs and the Twins.
Band of Brothers: They bicker and fight a lot, but they're always there for each other. At least until Peter says something else.
Born Unlucky: Tootles. He misses out on more adventures than anyone else because they have a tendency to happen when he's just left the scene, and if something bad happens it generally happens to him.
Butt Monkey: Again, Tootles, though Slightly also has traces of this.
The Dividual: The Twins are the Twindividual variety; they don't even have individual namesnote excluding Peter Pan in Scarlet, where their names are eventually revealed to be Marmaduke and Binky and are never seen apart. Some adaptations has them as Single-Minded Twins.
To a lesser extent, the Lost Boys as a group can be said to have a Syndividual thing going on; they have their individual personalities, but it's as a group they're important, and most often they only appear as a group.
Interestingly, the "Single-Minded Twins" trope is subverted a few times in the play and the novel; "First Twin" is said to be prouder than his brother, "intellectually the superior of the two", and the best dancer of the group. The truth is that the twins intentionally act as much alike as possible because Peter, who doesn't have a realistic view of what twins are, thinks that they should.
Second Twin: Slightly, I dreamt last night that the prince found Cinderella.
First Twin: Twin, I think you ought not to have dreamt that, for I didn't, and Peter may say we oughtn't to dream differently, being twins, you know.
Gender Bender: Tootles in Peter Pan in Scarlet, as a part of the books recurring and exaggerated "clothes make the man" theme — when the now adult Lost Boys become children again by dressing in their children's clothes, Tootles (who only has daughters) is forced to dress as a girl, and so he physically becomes a girl, and starts acting like a wannabe Princess Classic — and like Wendy, Tinker Bell and Tiger Lily before him/her, develops a crush on Peter and begins displaying traces of Hopeless Suitor.
Growing Up Sucks: Unlike Peter, they do eventually grow up (if we exclude the Disney version), and quickly discover it's not as much fun as they'd thought. Not played completely straight, though, as several of them actually turn out to have rather nice (if less adventurous) lives as adults.
Hidden Depths: Tootles, not surprisingly. He even grows up to be a judge.
Age Lift: Most notably with Michael in the 2003 movie; in the book he's around three or four, but in the movie he's eight. John is eight in the book, ten in the musical and around eleven or twelve in the movie. Averted in the Disney movie, which has them roughly the same age as in the book.
Annoying Younger Sibling: Partially subverted, in that Wendy is the one who insists on bringing them along — though Peter blatantly doesn't care about them and can take or leave them.
Tagalong Kid: Both of them, to some extent, but Michael especially.
George and Mary Darling
The parents of Wendy, John and Michael. Mary is a loving, accepting and beautiful woman who nevertheless is a bit of a Control Freak, and George is a temperamental and overly-proud, but ultimately kind and generous man. They make the mistake of going to a party on the same night Peter Pan is hunting for his shadow, and in the novel they go for months without seeing their children, but in the Disney version the children return before the parents have returned home from the same party. Also in the Novel they end up adopting all the Lost Boys.
Break the Haughty: George Darling is proud, blustering and sometimes unthinkingly cruel, but when these traits are indirectly leads to his children vanishing he is heartbroken, and becomes both humbler and kinder as a result.
Cool and Unusual Punishment: In the novel, George inflicts one on himself after Peter has flown away with the children; blaming himself because he had banished Nana to the kennel so she couldn't protect them, he moves into the kennel himself and refuses to leave it until the children are back. He even arranges to have the kennel (with him inside) carried to and from his work every day so he can still work but keep up his self-inflicted punishment. He becomes rather famous around London as a charming eccentric as a result, causing Mary to wonder whether he really views it as a punishment anymore or whether he's started to enjoy it.
Jerk with a Heart of Gold: George can often come across as overly unsympathetic, almost antagonistic, thanks to his pride and temper, but he does have a heart, and he does love his children very much.
Red Oni, Blue Oni: Calm, mild-mannered and soft-spoken Mary is the Blue Oni to George's blustery, temperamental Red Oni.
Parents as People: Mostly noticeable with George, who is not a perfect father by any means, but does try.
The Darlings' substitute-for-a-nursemaid; a huge but loving Newfoundland dog. She was originally a stray who "belonged to no one in particular" before the Darlings took her in, and though she is subject to a bit of gossip, and George Darling occasionally suspects she thinks the children are her puppies, she is as good and attentive a nursemaid as any and much beloved by the family.
Generation Xerox: In Return to Neverland, she's replaced by her Suspiciously Similar Substitute Nana II, who looks and acts almost exactly like her — the main difference being that she wears a war helmet and backpack rather than the nurse's cap of the original Nana.
In Peter Pan in Scarlet we meet her great-great-great-grandpuppy, simply called "the puppy," who even as a small puppy looks enough like Nana that Peter think it is Nana and that she's shrunk in the wash. (Unlike Nana, though, the puppy is noted as being a very poor nursemaid; it happily licks the children goodnight and lets them use it as a pillow, but doesn't bother at all to make sure they brush their teeth.)
Nearly Normal Animal: She's smarter than the average dog, capable of doing almost all the things a human nursemaid would do.
Captain Hook's greatest nemesis, apart from Peter Pan. It was the crocodile who ate Hook's hand, and liked the taste so much that ever since it's been stalking Hook, hoping to eat the rest of him as well. It's easy to hear whenever it comes, though, because at one point it also ate a ticking clock — and the sound of this clock, still ticking in the crocodile stomach, warns Hook to its presence.
Jane is Wendy's daughter and shows up at the end of the original book/play and a few other adaptation, as a new girl to be Peter's "mother" in Neverland. When she grows up she has a daughter named Margaret, who takes on the same role. While Jane has a very small role in most versions of the story, she is the main character of Disney's Return to Neverland where she is kidnapped by Hook and his crew (under the mistaken impression that she's Wendy) and taken to Neverland to be used as bait to trap Peter. This incarnation of Jane is characterized as always trying to have a practical attitude towards life, much like her grandfather George.
Broken Bird: The song "I'll Try" from Return to Neverland explains her inner thoughts quite well.
Constantly Curious: Her main character trait in the original novel; she's described as having an almost permanent "odd inquiring look, as if from the moment she arrived on the mainland she wanted to ask questions."
The Cynic: Return to Neverland pretty much has her as Peter's antithesis: Where Peter doesn't want to grow up, Jane doesn't want to be a child. Hence, she has an extremely cynical and often humorless outlook on things.
