Cinderella Circumstances: She is a daughter of a rich gentry woman and a clergyman. However, her parents died. Her mother's brother kindly took her as his won daughter, but unfortunately he died as well. His wife treats her as the worst wicked stepmother there ever was.
Deadpan Snarker: "I had green eyes, reader, but for him they were newly dyed I suppose."
Did You Think I Can't Feel?: Twice: Once when she calls the old aunt out, and asks Mrs Reed if she thinks she could live without any kindness or sympathy. The other time is when she gets provoked by Mr Rochester into the "our spirits are equal, yadda yadda" speech.
I Just Want to Have Friends: As a child. She even tells Helen that she'd willingly get kicked by a horse if it would make Helen love her.
Mama Bear: Towards Adèle. She doesn't take it well when people mistreat her, but as a governess, she often cannot do a lot.
Orphan's Ordeal: Both her parents died when she was very little, practically a baby. Her uncle Reed loved his sister and took her as his own, but he died soon too, and her aunt hated her like plague. Her relatives from her father's side exist, but they come in the picture much later in the story. Part of it was Mrs Reed's doing.
Plain Jane: Arguably the Trope Namer, although it's hinted that she's more attractive than she gives herself credit for.
Unexpected Inheritance: She ends up inheriting a large fortune from her paternal uncle, whom she never met in person.
The Unfavorite: Her aunt absolutely despised her. The reason was that Jane was a favourite of her late husband who seemed to prefer little Jane over his own children. She also didn't approve of Jane's character who was not a traditionally cute child.
Byronic Hero: He's dark and troubled, snarky, cynical and attractive despite his lack of good looks. Society frowns upon his loner's ways, but deep down he's a good person who suffered horribly; though admittedly, some of it was at least partly his doing and his fault.
Deadpan Snarker: He snarks a lot at practically everybody. He's so deadpan that he manages to play a role of a gypsy woman, telling fortune to several female characters. Only one of them figures it out.
Gold Digger: Married Bertha for her money, and also for her renowned beauty. However, it was mostly due to his family's meddling. His father and his elder brother wanted him to be wealthy and genteel. Little did they know what they had got him into.
Looking for Love in All the Wrong Places: Céline is simply the only mistress Rochester names. He tells Jane there have been other women, but none of them were what he wanted in a long-tern relationship.
Manipulative Bastard: He plays many strange tricks on Jane to make her jealous and to keep her from finding out about Bertha.
Tall, Dark and Snarky: He's described as very dark and nearly black. He compares himself to Hephaistos, a Greek god of fire and black-smithery. Jane agrees. He appears intimidating to nearly everybody. It's partly his defence mechanism because he suffered a lot, but it's easy to imagine him as a snarker even in his young age with his family.
Break the Haughty: She a very proud and haughty rich woman at the beginning of the novel. Her son failed her, however, ruining their family. She's also very uncomfortable being humbled by Jane.
Doting Parent: To her own children. They do not thank her for it. Especially John.
Jerkass: She's mean and nasty to Jane, never showing her a shade of affection, yet believes herself to be her nice benefactress, worthy of praise and admiration. What an effing bitch!
Karmic Death: She never did anything to redeem herself and never regretted the way she treated her poor orphaned niece. She died when her son was dead, her family in debts and her daughters barely caring for her. Sad fate, but she fully deserved it. And it was good riddance.
Kick the Dog: Concealing Jane's existence from her existing relatives.
Jerk with a Heart of Jerk: He takes after his mother in this regard. He seems to enjoy torturing young Jane. When he becomes an adult, he acts like a jerk to his mother as well, constantly asking her for money and never showing her love or respect.
Holier Than Thou: Shown especially in the scene when he forces a girl to cut her naturally curly hair when his own wife and daughters wear fake curls.
Hypocrite: In how he provides for his family, as opposed to how he provides for the girls at Lowood. Bites him in the ass badly later.
Jerkass: He's a mean one. He treats the orphaned girls and their teachers like they're worthless. He's evil and stupid, and he doesn't even know it.
Sinister Minister: As a clergyman of rich, honourable and influential family, he has quite a strong position, but he has a sick, twisted mind. For instance, he scares Jane with his idea of hell and horrible religious teachings.
Cool Big Sis: She becomes one to Jane when Jane grows up and becomes a teacher at Lowood.
Cool Teacher: She's very intelligent and treats her girls wonderfully.
Nice Girl: She's wonderful to Jane and Helen, treating them like her equals (an adult woman to little girls in Regency England, no less) or like an affectionate friend.
Reasonable Authority Figure: The headmistress of a practically Spartan school, Miss Temple is nevertheless kind to the girls and insists that they be given decent food, and enough food at that, despite Mr. Brocklehurst's idea of an adequate budget.
Died in Your Arms Tonight: Jane climbs to her bed and they fall asleep together. Helen never wakes up. Jane only remember that somebody lifted her up and took away.
Ill Girl: She suffers from consumption, poor lamb. It's portrayed quite realistically.
Too Good for This Sinful Earth: She was the sweetest, cutest girl imaginable and her spirit was noble and dignified (almost scary for a child). Such girls are not made for this evil world. She would suffer too much.
Mrs. Alice Fairfax
Apron Matron: She's a housekeeper at Thornfield and she has mother-like vibes about most most characters. She might not be the most perceptive or the brightest woman on Earth, but she is kind and caring.
Cool Old Lady: She's all right. She has some kind of motherly affection for Jane and Adele. Other servants at Thornfield seem a fairly happy lot, so it's clear she treats them fine.
Stepford Smiler: Mrs. Fairfax is always pleasant, despite the implications that she knows, and disapproves, of her master's behavior. Even when she talks to Jane about the marriage proposal, it is in the spirit of a friendly warning and nothing more, despite her alarm.
Missing Mom: Her mother abandoned her and never cared for her after that.
Morality Pet: To Rochester. The man has serious issues, but his treatment of Adele shows him in his best life. He gave her a good home even though she's most likely not his biological daughter. He's sometimes a little mean to her, but he's never abusive. All in all, what Rochester does for the little girl is admirable.
Parental Abandonment: She believes her mother has died, but Rochester seems to imply that her mother just dumped her and ran off.
Spoiled Sweet: She's a spoilt child which is a thing Jane doesn't like, but she's not beyond the point of possible improvement.
Child Hater: She has no patience for Adèle and is making plans to pack her off to boarding school almost immediately after setting foot in Rochester's home.
Jerkass: She's quite cruel to people, especially to Jane and little Adele. She also stealthily insulted one sweet lady of her social standing, abusing her slightly superior knowledge.
Rich Bitch: She's a beautiful woman from a rich family background, even though she specifically has no money of her own. And boy, is she a bitch! She gleefully spoke about how horrible all governesses are, perfectly aware of the fact that Jane is in the room and can hear it as well.
Big Brother Instinct: Saves his sister's honour by stopping the wedding of Rochester to Jane, which would have been illegal as Bertha is still alive.
Chick Magnet: Rochester's female guests take quite a shine to him.
Extreme Doormat: He behaves very submissively to Mr Rochester. Said gentleman doesn't take it too well, but at least he appreciates that he's capable of feeling.
Minor Injury Overreaction: To be fair, it was probably quite a painful wound, but he was ready to give up and die after Bertha attacks him.
Uncanny Valley: In-Universe, Jane describes him as being right out of it:
"...I like his physiognomy even less than before: it struck me as being, at the same time, unsettled and inanimate. His eye wandered, and had no meaning in its wandering: this gave him an odd look, such as I never remembered to have seen. For a handsome and not unamiable-looking man, he repelled me exceedingly..."
The Fundamentalist: St. John is just as hardcore religious as Brocklehurst, only he is entirely sincere about it. He believes he must be a missionary and that to do less is to ignore God's plans for him. He goes so far as to accuse Jane of refusing God by refusing to marry him.
The Missionary: His ultimate career choice. He sees it as his noble calling.
Pretty Boy: Jane describes him very handsome. He's compared to a God from classical mythology.
Spoiled Sweet: She's a spoilt girl who knew nothing but indulgence, but she's never jerkish or proud.
Mr. John Eyre
Bus Crash: Jane, as well as the readers, never get to meet him. He dies and leaves his fortune to Jane.
The Ghost: He's spoken of quite a lot, but he never appears himself.
Long Lost Relative: He's Jane's paternal uncle. He wanted to take care of Jane at one point, but Mrs Reed lied to him that Jane had died. He only finds out otherwise when Jane writes him about her impending marriage.
Self-Made Man: He's a businessman who represented a wine-selling company. He has made quite a fortune.
