Not So Above It All: Meg is the most responsible and level-headed sister but she can be vain and self-indulgent on occasion — if not borderline greedy. Also, after her marriage she makes some questionable decisions, as a wife and as a mother. Of course she learned her lesson at the end.
Fiery Redhead: Chestnut brown, which has red in it, depending on one's interpretation of chestnut). She is also, however, almost always a redhead in The Musical, as that is how she was initially played by Sutton Foster.
Hot-Blooded: The most impulsive, hot-tempered and passionate of the four girls.
Important Haircut: One of Jo's turning points in the first book was willingly cutting and selling her gorgeous Rapunzel Hair to help the family after Robert falls seriously ill and Marmee must go take care of him. Everyone reacts as if she was the victim of a Traumatic Haircut, but Jo is calm about it... until she's alone with Meg that night and confesses that it wasn't as easy as it seemed.
Kick the Dog: Ignores any attempts Amy makes at making up after their fight, then purposely neglects to tell her about the rotten ice when they go ice skating.
Lethal Chef: That time she invites Laurie for dinner and tries to cook, making a horrible mess.
Spirited Young Lady: Given her outspoken, tomboy nature and her intellectual gifts. Though she starts off as more of a Tomboy, she gradually conforms a bit more to society's standards as she ages: witness her very domestic mending of Professor Bhaer's clothes as an adult. Meg plays the Proper Lady in contrast.
Tomboy and Girly Girl: Tomboy to Amy's Girly Girl. Jo is a headstrong Spirited Young Lady with a fiery temper who rejects female values and convention and finds sentimentality utterly repellent. Amy is a vain, spoiled artistic beauty, obsessed with her appearance, who aspires to be the perfect Proper Lady (and she actually becomes one when she grows up).
Tomboyish Name: Jo is short for Josephine. She's also a tomboy herself.
Tomboyish Ponytail: In the 1987 anime, her hair is in a ponytail, which may or may not be historically inacurate
Tsundere: Type B. She is a nice girl, but sometimes can be brutally honest and has a bad temper.
Vitriolic Best Buds: With Laurie. This is exactly why she turns him down when he proposes to her.
Ill Girl: She had scarlet fever in the first book. It doesn't seem much now, but actually scarlet fever can have very serious side-effects in the heartthat were fatal and untreatable back then, and those are what killed poor Beth in the end.
Shrinking Violet: Her main flaw. She finds it very difficult, even painful, to talk to people outside her immediate family, and stops going to school out of shyness. She gets... a little better, but not too much.
Too Good for This Sinful Earth: Especially played up in the musical, where her death occurs offscreen but is preceded by a sweet duet about destiny between her and Jo, and about how Jo is meant for greater things than taking care of her ill sister.
Break the Haughty: Twice, in the first book. First, she's punished and humiliated at school when she attempts to be In with the In Crowd and breaks school rules to do so. Second, when she replaces Jo temporarily during Beth's illness... and has a HARD time pleasing Aunt March.
Everyone Loves Blondes: She always knew that she would marry a man with money. She can really do it because she is, as described by the author, a 'regular snow-maiden' with curly golden hair and blue eyes, 'pale and slender', and 'always carrying herself' like a very proper young lady.' She also has the culture of being interested in art, theater, and traveling.
Jerk with a Heart of Gold: She has a good heart behind her vain and self-centered behaviour. In fact, she breaks down crying in the first book when she writes her own testament while Beth is sick, and then the very possible prospect loss of Beth sinks in.
She's All Grown Up: She believed herself to be ugly as a child due to an accident involving her nose. Turns out she grew into quite the cutie.
Spoiled Brat: As a child she is prone to behave in a vain and self-centered way, especially if she doesn't get what she wants.
Tomboy and Girly Girl: Girly Girl to Jo's Tomboy. Jo is a headstrong Spirited Young Lady with a fiery temper who rejects convention and finds sentimentality repellent (except in books). Amy is a vain, petted artistic beauty, anxious over her appearance, who aspires to be the perfect Proper Lady.
Jerk with a Heart of Gold: If she does like you, she might help a little. She genuinely liked Amy despite giving her a hard time and worried over Beth's illness, and when she died, she left her Plumfield house to Jo.
She complains about and criticizes her nephew's family to the point where Marmee can barely stand her, but due to the family's poverty, she offered to adopt one of the girls, supplies the money for Marmee to visit Father, surreptitiously provides Meg with an enormously overstocked linen closet as a wedding present despite swearing not to, and Amy notices that, for all of her riches and treasures, the most precious to her is her wedding ring. Aunt March is a cross, sour old lady, but she definitely has the heart of gold down, too.
The Smart Guy: Jo and later her family come to respect his intellect and classical education.
Unfortunate Name: His last name, which is not "bear" or "beer." Often lampshaded in the book, particularly when Laurie refers to Plumfield as a "Bhaer-garten," punning off the German "Bier-garten."
John Laurence "Demi" Brooke
Big Brother Bully: He loves Daisy, but if he told her to jump off a bridge, she'd do it. And if he got into his head some sort of fanciful idea about jumping off bridges, he would probably ask.
Incorruptible Pure Pureness: He's very well respected and admired among his classmates for this reason, is above reproach in any serious trouble (though he's still a little naughty sometimes), and the other boys wouldn't even consider attempting to convince him to do anything really morally wrong.
Punny Name: He's named after his father, so the family would have been stuck calling him "Jack" to keep from having two Johns running around, but Laurie suggested naming him "Demijohn" ("Little John") and calling him "Demi" for short... which also happened to be alliterative with the nickname Aunt Amy gave to his twin sister.
