Isabella Swan is the main character of Twilight. After her mother gets remarried, she moves from Arizona to Forks to live with her father. Having gone in only expecting another ordinary stay at the town, she's confronted with a heavenly surprise when she spots an impossibly gorgeous group of newcomers known as the the Cullens at her local highschool. And, among them, her subsequent soulmate, Edward Cullen. It's only through a sequence of contrived events, she discovers that these God-like beauties are actually a clan of fabled creatures known as vampires. But, rather than being shocked by this discovery, instead she decides she's in love with Edward leading them to hook up and venture into a forbidden love. She describes herself as being klutzy, easily bruised and of weak constitution. She also claims to be quite plain in appearance, but takes pride in being very well read, and even moreso in being able to function by herself and having the wisdom of a woman twice her age.
Afraid of Blood: It causes her to faint in the first book, though there is nothing delicate about it and her description of the incident.
She's pretty delicate: she nearly fainted just from smelling a few drops of blood from part-way across the room.
All Girls Want Bad Boys: She still wants to date Edward, even though he is "dangerous." She also starts to gain interest in Jacob only after he becomes a werewolf.
However, she doesn't seem to use the stereotypical justifications ("I can change you", "He was just having a bad day"), and was originally creeped out by Edward's hostile behavior towards her (though she was, amusingly, always Distracted by the Sexy). Her reaction to Jacob's change of personality is extremely nuanced, basically: "How dare you abandoning me after making me emotionally dependent! Also, I think you joined a cult. Also, that's hot."
Weirdly she was put off by Edward when he first acted gruff with her, but is never deterred by him stalking or manhandling her, nor by the knowledge that he had killed hundreds of people.
Also when Bella finds out Edward has broken into her house, more than once, even before they were dating, to sit in her bedroom and watch her sleep, Bella is more concerned that he heard her talking in her sleep.
Upon discovering that Edward is a vampire and can read minds, she freaks out... because he says he can't read hers, which makes her think that she's the freakish one. This is Lampshaded.
Audience Surrogate: Pretty much her entire purpose in the series is being the reader's stand-in so that Edward is speaking to them
It fits better with this after Bella and Edward are actually in a relationship, and she allows him to snuggle with her every night and watch her sleep.
Berserk Button: DO NOT hurt Edward, her family, or anyone that she holds dear. She will go from mild-mannered to fiery and violent.
Turns out that Jacob calling Bella's daughter "Nessie" was a HUGE berserk button for her, considering that Nessie is also the name of the lochness monster.
Better as Friends: With Jacob. Knowing that Jacob has feelings for her and knowing that he's going to go into battle and get himself killed, Bella kisses Jacob. When Edward asks Bella if she loves Jacob, she tells him that she loves him (Edward) more. Later, Jacob is accepted as part of the family despite the romance between Bella and Jacob.
Betty and Veronica: The Archie for Jacob's Betty and Edward's Veronica. She chooses Edward.
Birthday Hater: She hates the attention and how it reminds her that she still ages while Edward doesn't. She gets somewhat better in Breaking Dawn, though. She freaks out a bit when Alice wishes her a happy nineteenth birthday, but calms down since she doesn't grow anymore. Furthermore, she gets her own dream cottage as a birthday present, and loves it.
Bitch in Sheep's Clothing: Almost certainly unintentional, but she often comes off as this due to her poor treatment of others and rather uncharitable thoughts about others appearances.
Cool Car: Drives a 1963 Chevy stepside pickup. In BD, her pickup crashes, and first gets a Mercedes Guardian and then a Ferrari.
Cool Loser: Bella is an inversion. She's socially awkward, clumsy and generally uncool, but everyone warms up to her the minute she gets to town and soon enough she has her own little circle of friends.
Deadpan Snarker: Her snark can easily go over the line, though. In the books, Bella tells a number of dry jokes with such a straight face that the others can't tell if she's trying to be funny
Description in the Mirror: This is Bella's occasion for describing her own appearance. She considers her appearance unremarkable, but the description she gives suggests good looks, similar to those of the author.
Dude Magnet: And she seems pretty oblivious to it, too. When she does notice (like with Tyler in Twilight), she seems annoyed.
Dull Surprise: Bella in the movie never has a discernible reaction to anything much, from death threats to getting married. The only time she reacts to anything is when she breaks her hand by hitting someone.
Extreme Doormat: She might as well have the word Welcome tatooed on her forehead since she's more than willing to let Edward dictate her every decision and actions...regardless of her actual thoughts on the matter.
Fainting: Bella has an extremely weak constitution, and faints at the smell of blood as well as when feeling overpowered. This isn't fake fainting to look delicate, nor a deliberate ploy from the author to meke her look this elegant. She mentions without much restraint that she came that close from throwing up in one occasion. This is just Stephennie Meyer's way to remind us that Bella is very fragile and helpless.
And when Edward breathes on her, don't forget that!
Interestingly, the subject itself is never treated as a moral dilemma. Bella loves her baby, so she keeps it. But then, the message was perhaps Good Girls Want Children, which would be all the more shocking.
Growing Up Sucks: Bella thinks that she should not be any older than Edward physically when she becomes a Meyerpire despite the fact that being slightly older than Edward would not cause too many negative effects for her as a Meyerpire.
She more or less drops this opinion in Breaking Dawn, after figuring out how great sex is as a human. She's turned into a vampire not long after and still thinks it's fantastic.
Idiot Hero: She mistook a VHS recording of her mother's voice projected through a phone for her actual mother, took ages to figure out that it was Victoria organizing the Seattle Army despite rather obvious evidence, is incredibly dense towards the feelings of others, tends to forget information when it's already been stated right in front of her, among many, many other instances.
Informed Ability: She is supposedly wide-read, but never references more than a small handful of books, and they're only the kinds any high schooler had to read in English 101.
Subverted in Midnight Sun, when she is seen reading Sense And Sensibility for fun.
In the first book she mentions, several times, that she thinks of her mother, Renee, as her best friend. However she barely thinks about her mom after moving to Forks and neglects to e-mail her when she arrives, acting exasperated that hey, after two or three days Renee is getting kind of worried.
Informed Flaw: Bella spends so much time talking about how "plain" she is. However, boys are still all over her.
The writer's not so subtle way to try and make us believe that Bella is modest.
In-Series Nickname: Bella is her preferred name in the series as opposed to her full name Isabella. Some of Bella's other nicknames in the series include Bells and Bell (both used by Charlie Swan and Jacob Black), Arizona (used by Mike Newton), Spider Monkey (used by Edward Cullen), Vampire Girl (used by Emily Young and Embry Call), Leech Lover (used by Leah Clearwater and Paul Lahote), and Swan Girl (used by Emmett Cullen).
Instant Expert: Sure as a human Bella is a hopeless klutz. But, once she's a vampire she's free of any of the consequences faced by most most newborns.
Inter-Class Romance: With Edward. While Bella is from a working class status, Edward comes from a wealthy background.
Interspecies Romance: With Edward before she was turned into a vampire by Edward in Breaking Dawn: Part 2.
The Load: She doesn't do anything remotely useful until Breaking Dawn and it's because of her bloodthirsty monsters keep showing up and attacking people in the surrounding areas. In the first book, James is attracted to her scent. In the second, so is Laurent. In the third, Victoria wants revenge for James. In the fourth, it's her daughter that causes the Volturi to come. Every major monster clash in all the books is a result of Bella.
Love Makes You Crazy: Particularly lampshaded in the parts of the story (New Moon) where Bella is involuntarily separated from Edward for a prolonged period. She starts seeing visions of him, hearing voices, and even intentionally putting herself in harm's way to evoke these reactions.
Love Makes You Dumb: Fits the bill whenever her emotions get out of control, if not the pesky consequences. The first book hits the nail on the head when she can't tell the difference between a recording of her mother's voice in a home video playing on a VCR in the background and her mother's actual voice calling for help, though this is probably justified because of her anxiety, and everything that just happened in the first book, at this point.
Love Martyr: She is even explicitly compared to a legendary Love Martyr from a true story. She exploits this because things worked out for the Love Martyr's love ones because of her attitude.
Manipulative Bitch: Sometimes she uses and toys with people and the feelings of those around her (epecially Jacob) to get her way.
Mama Bear: In Breaking Dawn, she flies off the handle when she learns that Jacob imprinted on Renesmee.
Martyr Without a Cause: Bella is a variant. It's not that she wants to be a hero, it's that, as other characters sometimes lampshade, she blames herself for anything and everything that goes wrong. This leads to the same type of self-hatred (if not the same quantity) as The Atoner, and while she doesn't often have the opportunity to risk her life, she clearly considers herself more expendable than those around her, particularly Edward, but also her mother, father, unborn baby... (this also seems to be responsible for a good deal of reader hatred, particularly from those who think she's merely Too Dumb to Live, but that's neither here nor there).
Probably unintentional, but it is still interesting to note that Bella's last name, Swan, has a meaning in the real-life vampire subculture. Swan is used to refer to people involved in the vampire community, but who are not vampires themselves.
Also probably unintentional, but given the conflicts she ends up causing, one considers the Latin translation of "bella": wars.
Must Not Die a Virgin: Bella wants to experience sex with Edward while she is still human, before she gets changed into a vampire. Doubles as a case of Too Dumb to Live, since Edward explicitly warns her that because of his super-strength, the experience will quite likely be extremely traumatic or even fatal.
Neutral Female: Really, whenever she's confronted with Edward, Jacob, or one of the Cullens outright forcing her into something she doesn't want, at most, she'll just pout while submitting to their will with no complaints. No speaking up for herself. No opinions or trying to reason with them; basically being reduced to a human traveling-bag.
Narrating the Obvious: She is quite an unobservant narrator of her own story, so half the time she doesn't notice what should be completely obvious to the other characters and/or all the readers.
Nice Shoes: When going to the prom, much to her own frustration.
Bella: I'll probably break my other leg. Look at this shoe! It's a death trap!
No Periods, Period: Played straight with Bella, who, despite having yummy blood, does not trigger a vampire feeding frenzy once a month. Handwaved by saying that menstrual blood is 'dead blood'. An Anatomy Fail on Meyer's part when you realize that menstrual blood has been proven to be cleaner/newer/FRESHER/more alive than normal blood.
Raven Hair, Ivory Skin: Bella is described as having a very pale complexion with long, straight, dark brown hair. Even before she became a vampire and inherited god-like beauty, Bella was rather pretty, as she unintentionally attracted the attention of several boys in school, not just Edward.
Satellite Love Interest: Our romantic heroine and POV character herself. We never learn much about her life in Phoenix, and although she easily makes friends in the beginning of the first novel, she immediately dumps them to be with Edward. Her whole life revolves around Edward, to the point where she actually goes catatonic when he leaves her, and in the last book she turns into a vampire, and completely leaves her human life behind her for a life with her Edward. She also has no character development at all throughout the books. At one point her mother literally compares her to a satellite around Edward—always orientating herself to always be near him—and she agrees with her mother with no second thoughts.
Shrinking Violet: Played with. Bella describes herself as such but she comes off as antisocial rather than shy most of the time.
Tomboy and Girly Girl: Bella would rather read books or fix cars than shop or mess with her appearance. Alice and Rosalie love shopping, makeovers, and are overall very feminine.
Took a Level in Jerkass: She was rather edgy as a human, but once she becomes a vampire, she becomes much more vicious.
Took a Level in Kindness: While rather edgy and manipulative in the films, she's this compared to the book version where we see her thoughts, which consist mainly of her insulting and belittling her father, her "friends", and pretty much everything that isn't a Cullen.
Unwanted Harem: A female example of this with a total of five guys in love with her, two of them supernatural. And she didn't have any boyfriends before moving to Forks.
What Measure Is a Human?: Bella doesn't seem to care about fact that Edward and some other Cullens killed some humans in their past. She finds it "only natural" for Edward to go through this phase. She also doesn't care as long as her guests in Breaking Dawn go out of town to find and kill their food.
Wise Beyond Their Years: Having learned to take care of her mother over the years and being naturally responsible, Bella had developed into a very mature person, especially for her age. She even starts out Twilight by telling us that she's prepared to die in the place of someone she loves. Once she's fallen in love with Edward and her leaves her in New Moon this is subverted as Bella turns out to be immature, whiny and lacking in self-control as first seen when she throws tantrums at her parents for trying to get her to move back with her mother.
A 108 year old vampire gifted with the ability to read minds. Having first encountered Bella in biology class, he's quick to discover that her floral scented blood evokes a intense, lethal craving. But rather than giving in, he settles for sneaking into her room at night, intrigued by the fact that he can't read her mind. Though he resists the urge to eat her, he'll stop at nothing to claim he's a soulless monster unworthy of redemption. And despite his claims of being a threat to her life, he (a century old vampire) decides it's fine to pursue a relationship with a 17 year old girl anyway. He was turned when he was 17 and dying of Spanish flu.
The Ace: How Bella sees him, but apparently all the vampires qualify compared to the humans.
Deliberate Values Dissonance: Edward is from the early 1900s. Some of what he does was perfectly acceptable in his native time. Other parts of his behavior, like sneaking into a girl's room every night to "protect" her, would have gotten Victorian/Edwardian fathers to take out the shotgun (or send the footman with a club).
Heroic BSOD: Edward also has one when Bella tells him she is pregnant.
Heroic Willpower: Edward's resistance of Bella's blood makes him poster boy for this trope. Of course, both Edward and Bella have to resist their regular sexual lust too, for reasons of safety and morality.
Horror Hunger: For Bella's blood. The scent of Bella's blood drives him crazy.
The Hunter: Edward preying on criminals during his "rebellious years".
Immortality: Edward is incapable of physically aging. He also has the ability to live forever without getting sick or dying.
Edward is a Type V and Type X.
I Am a Monster: Struggles with this, especially since he's murdered people in his past. However, they were all criminals, and, as Bella points out, he probably saved more lives than he took.
Invisible to Normals: Edward's stopping of the van about to crush Bella with his bare hands with no one but Bella realizing could fall under this, and it is even mocked in Mark Reads Twilight, where he says this is part of an overused idea he calls "The 'I Am Going To Do Something Spectacular And Clearly Attention-Grabbing In Front Of Plenty Of People, Yet No One Is Going To Notice Except (Conveniently) The Main Character' Phenomenon."
Edward Cullen: I'm from a different era, things were a lot less complicated. And if I'd were met you back then I would have courted you, would've taken chaperoned strolls, iced tea on the porch and...I may have stolen a kiss or two but only after asking your father's permission. I would have got down on one knee and I would have presented you with a ring. [he puts a small ring box in her hand and kneels in front of her]
Rescue Romance: Edward and Bella were already secretly interested in each other, but it was Edward saving Bella from Tyler's out of control van that laid the groundwork for their relationship.
Serial-Killer Killer: When Edward was younger, he rebelled against Carlisle's animal blood philosophy, so he used his mind reading powers to only feed on rapists and murderers. But even that proved to be too much for his conscience.
Sickeningly Sweethearts: With Bella. Edward is fascinated by even the most mundane things about Bella and she gushes about how gorgeous he is every time he enters her field of vision and once even swoons over how good his breath smells.
Wife Basher Murderer: After "rebelling" against Carlisle to try out a more "traditional" vampire lifestyle, his first act was to track down, torture and murder Esme's abusive ex-husband before escalating to judge, jury and executioner of anyone he deemed "evil".
You Need to Get Laid: Edward's broodiness and fatalism has been linked to the fact that he has never had sex in almost a century. Once he gets married and does the deed he certainly becomes less stressed.
Jacob first knew Bella when they were just children, and they lost contact for years while she was away. He tried to push for a more romantic relationship, but by the time he made his intentions clear, she only had eyes for Edward. He became a werewolf in New Moon.
Cleaning Up Romantic Loose Ends: Jacob in the third book suffers from derailment: he goes from a friendly, devoted guy to a possessive jerk to better enable the canon couple. Then, in the last book, he imprints on Bella's newborn baby and conveniently is no longer at all attracted to Bella. In fact, with the notable exception of Leah, basically every major character is wonderfully paired off by the end of the series.
Cock Fight: With Edward over the affections of Bella.
Derailing Love Interests: Turns from his nice, friendly, easy-going Twilight self into a possessive jerk in the last pages of New Moon and coming to a peak in Eclipse. According to some, this is to make way for the Official Couple.
Although in many ways, his derailment actually makes him act more like Edward, leading to an alternate interpretation that this was supposed to make him more appealing. (Or that Meyer just can't write her characters very distinctively.)
Distress Ball: Jacob ends up grabbing this when he shoves Leah out of the way just to be crushed by a Newborn Vampire. The book attempts to make it out that Leah was the one in distress because she was fighting the vampire alone to begin with, but... both her and her little brother have defeated newborns in single combat before, and nothing about this fight really necessitated Jacob shoving her out of the way. Of course, all the blame for this goes to Leah. Not to mention the entire reason Jacob gets hurt is that he was too slow for the vampire making this an What an Idiot moment on an even higher level - Leah is the fastest werewolf.
Forgot I Could Change the Rules: Jacob has to submit to the will of Sam, the Alpha Wolf. When Sam orders him to help destroy the Cullens (and Bella), he remembers that he was born to be the Alpha but he had voluntarily given up the birthright. Choosing to become the Alpha frees Jacob from obeying Sam's orders.
Hot-Blooded: Literally. His body temperature is about 108.1 at rest. The reasons behind it verge into Artistic License territory, but they're not unreasonable.
In-Series Nickname: Other than Jake, which is what Bella and everyone else often calls him, some of Jacob's other nicknames in the series include Chief Jacob (used by Bella Swan), Uncle Jay (used by Claire Young) and Jacob Wolfe (used by Bella Swan).
Intimate Healing: Jacob has a higher body temperature than normal, so he's the obvious choice to help Bella avoid hypothermia.
Ungrateful Bastard: His response to Leah telling off Bella for the way she (Bella) has been treating him? He immediately jumps to Bella's defense when she starts crying, and gets mad at Leah for upsetting her, even though she stood up for him.
Wife Husbandry: As of Breaking Dawn, one way to interpret the Jacob-Renesmee relationship. Or any other form of imprinting.
Charlie Swan (portrayed by Billy Burke)
Charlie is Bella's father and the police chief of Forks. He is quiet and a bit of a loner, who enjoys watching sports and drinking beer. He mostly leaves Bella up to her own devices. He will occasionally try to interact with Bella, but she usually is too busy protecting him from the horrors he is not aware of to actually spend time with him as well.
Adults Are Useless: Bella's going through all of this, and Charlie barely steps in. When she becomes a vampire, he ends up keeping his knowledge of what has happened on a need-to-know basis. It has to be said, though, that this is only partly due to his discomfort with the strange goings-on; Bella and the Cullens know that if the Volturi find out he knows about vampires, they will either kill him or force the Cullens to turn him.
Badass Mustache: Billy Burke's impressive 'stache in the films has made him quite popular, even among the Hatedom.
First Name Basis: Bella almost always calls him "Charlie" instead of "Dad". She only uses "Dad" when she's particularly emotional or upset.
Locked Out of the Loop: Until Breaking Dawn when he begins to learn a bit of the world around him. He invokes this trope by asking Jacob and Bella not to tell him any more than the basic essentials.
Papa Wolf: The fact that Bella's moving to Forks was presumably the first time he'd seen her in several years did nothing to stop him from looking out for her. An example: When meeting Edward for the first time in the film, he's carrying a shotgun with him. Granted, it would have done nothing to Edward, but you've gotta give the guy points for trying.
Pair the Spares: By the end of Breaking Dawn, Charlie has begun dating Sue Clearwater.
Police Are Useless: Justified. There really isn't a practical way for the police to respond to vampire activity. He probably does okay against the everyday, run-of-the-mill crime, it just isn't shown because it isn't part of the story.
Covert Pervert: Mike, in Midinight Sun. Listening to his thoughts is Edward's equivalent of a Mind Rape, so he tries to concentrate on Angela's.
Disproportionate Retribution: Wordof God says Lauren fell prey to a modeling scam that cost her over a thousand dollars and a good chunk of her hair. What made her deserving of this? She made one relatively minor sarcastic comment about Bella.
Excplited in Midinight Sun. She keeps thinking that Bella isn't that interesting and decides to befriend Bella to create an interesting Girl Posse to bring attention to her. However, Breaking Dawn heavily implies that though self-centered and oblivious to Bella's feelings, she has come to genuinuely like her.
The patriarch of the Cullen clan, Carlisle's been around for centuries. The son of an Anglican pastor in the 1600s, Carlisle was turned after a fateful encounter while hunting vampires. Initially horrified, he tries many times to kill himself before succumbing to his thirst by drinking animal's blood. After being revived, he goes on to live out his immortal lifespan as a doctor and helper and eventually decides to create a companion for his growing loneliness. The rest is history.
Action Dad: Carlisle always knows what's going on and gets quite involved. Even if he hates violence and fighting.
The matriarch of the Cullen clan and Carlisle's wife, Esme's beauty is matched only by her gentle nature and great capacity for love. After meeting Carlisle as a young girl, she later married another man who turned out to be an abusive jerk. She managed to escape, while pregnant, but her child died shortly afterwards, robbing her of the will to live. After a near successful suicide attempt, Carlisle, who recognized her, transformed her. She fell in love all over again, and has since found solace in her big family of immortal adopted kids.
One of Edward's many adopted siblings, Alice used to be in a mental institution because she claimed to see the future. After being transformed into a vampire to save her from a sadistic hunter, she's managed to find Jasper and the Cullens and has lived with them since. She is funny, happy in nature and well adapted to living as a vampire and aside from Emmett is Edward's closest relative and ally. She adores Bella even before she meets her, just because she knew she will love her.
Badass: She isn't necessarily the greatest fighter, but it's hard to hit someone when they can see the future.
Beware the Nice Ones: She has been known to display a temper every so often. Such as when Emmett and Jasper are restraining James and she leaps onto his shoulders and tears his head off.
In the movie, Jane kills Jasper. Alice's response is to grab Jane and drag her to Wolf!Sam's waiting jaws. All Just a Dream, lucky for Jane.
Blood Knight: Shows shades of this in "Eclipse" when she finds out that Edward will be sitting out of the fight with the newborn army at Bella's request. Stating that he is going to be missing all of the fun.
The Fashionista: Loves dressing people up and throwing parties, especially if Bella's involved. She not only organized Bella's wedding, but packed her honeymoon suitcase, dressed her up in a cocktail dress and stilettos for her first post-vamp hunt, and filled up her closet at home with more clothes than Bella felt she could wear for a while.
In-Series Nickname: Some of Alice's nicknames in the series include Shortie (used by Jacob Black), Little Freak (used by Edward Cullen), Frightening Little Monster (used by Jasper Hale), and Psychic (used by Jacob Black).
Immortality: Alice has the ability to live forever without physically aging.
Magic A Is Magic A: How Alice's precognition worked seemed to vary each time it figured into the plot. Sometimes her visions are infallible, other times unreliable, and sometimes people can avoid showing up on her radar if they know the right tricks. Sometimes she can get visions of things she specifically wants to see, other times what she sees and when she sees it are totally random. Generally the only thing consistent is her power goes dark if the future involves a species she's never been, like a werewolf or half-vampire.
Adopted into the Cullen family after Rosalie, Emmett is a fairly jolly guy. Found by Rosalie after getting mauled by a bear, he was transformed and has been inseparable from her and the Cullens since then.
Brilliant, but Lazy: Has repeatedly (and, on Meyer's part, probably unintentionally) proven himself to be actually pretty smart or at least very sensible, as he's pointed out multiple ways to avoid conflict all throughout the series (see also The Strategist below). That being said, he appears to have zero interest in his education, and has never finished any particular degree simply because it bored him.
Determinator: Gives off this vibe, especially when Meyer described his constant need for rematches.
Double Entendre: Constantly makes jokes about Edward and Bella's sex life, around Charlie no less!
Sore Loser: A mild version, Emmett's reaction to losing is to keep asking for rematches until he wins.
The Strategist: Downplayed because it's only there for a single chapter, but the fourth book, he is the one to come up with a plan to defeat the Volturi, or at least keep them from killing the Cullens. And, at the end, it actually works.
The second kid to be adopted into the family. Rosalie is stunningly beautiful, even for a vampire, but she's really had a hard life. She grew up during the Great Depression, but managed well, and was even poised to marry a man who still had his money in those tough times, even though she didn't love him. She was then beaten and gang-raped by her fiancé and his friends while they were drunk off their rockers, and was left for dead in an alley. Taking pity on her, Carlisle transformed her and being with Emmett gave her a reason to keep going on. She's not really nice to Bella in the beginning, but grew to accept her later.
Blood-Splattered Wedding Dress: Noticeably averted: After becoming a vampire, she took revenge by killing her rapists including ex-fiancé while wearing a wedding dress (not hers, but one she had stolen for the occasion; she said she was quite melodramatic back then). However, she was very careful not to spill any blood, because she knew she wouldn't be able to resist it, and she didn't want any of them to be a part of her.
The Determinator: Usually around blood. While she momentarily loses focus when helping perform Bella's c-section, she's rather proud of the fact that she's never once tasted human blood.(As noted above, she didn't feed off her rapists/murderers, and she didn't attempt to change Emmett because she didn't trust herself to be able to stop).
I Just Want to Be Normal: She wants nothing more than to be able to have children and grow old with Emmett and would give up her beauty and immortality just for that chance. As such, she isn't thrilled with Bella's seemingly off-hand dismissal of potential motherhood.
In-Series Nickname: Rosalie's nicknames include Rose (used by the Cullen family), Kitty (used by Carlisle Cullen), Babe (used by Emmett Cullen), Blondie (used by Jacob Black), Ice Cold Barbie (used by Jacob Black), and Angel (used by Emmett Cullen).
Born in the Deep South, Jasper participated in the Civil War before being transformed. He lived out his early days training an army of vampires, but after the stress proved too much for him, he left, and later met the love of his existence, Alice, and has lived a peaceful existence with the Cullens since then.
Aloof Big Brother: To Edward, Emmett and Rosalie. He is the eldest of the Cullens children.
The Atoner: Jasper used to be a troubled vampire who endlessly killed others for sport. He has learned the error of his ways thanks to Alice and his love for her.
This is subverted in "Midnight Sun,” "Eclipse,” and the "Short Second Life of Bree Tanner."
Such as in "Midnight Sun", he had no issue with murdering Bella, an innocent girl in cold blood to "protect" Alice and the family's secret from what he deemed to be "a slight danger."
Then in "Eclipse," he had no issue with suggesting (and if Carlisle had not been against it) that the entire Cullen Clan eats innocent people to be stronger for their battle with the newborn army.
In "The Short Second Life of Bree Tanner," he is shows that he had no issue with abusing his power to entice Bree into attacking him so he could have an excuse to kill her after Carlisle offered her asylum.
Badass: One of the most badass characters in the series, as we learn from his past history, if not the biggest one, although we never get to directly see his sheer badass in the book. The movies made sure to remedy this, especially the 3rd one.
In the final battle we see all the Cullens and the Werewolves brutally fighting against the Newborns, giving it their all. Jasper's first move of the fight, however, is to literally punch a newborn's head clean off his body, and he spends the rest of the battle tossing them aside and ripping them to shreds like wet paper, with not one of the Newborns capable of stopping him.
It's a shame that the 4th book was what it was, as everyone would have loved to see Jasper in action and being the badass we know he has to be.
Getting Smilies Painted on Your Soul: Jasper can control the emotions of those around him, and according to Bella, it's impossible to feel anything but what he wants you to feel. It's also not a matter of discussion or consent.
Love Redeems: In regards to his relationship with Alice. Alice changed Jasper as a person.
Ooh, Me Accent's Slipping: Jasper has little to say throughout the movies until the Training Montage in Eclipse. Up until then, he has a rather generic American accent, but in Eclipse he remembers he was a Civil War veteran from Texas replete with a... jarring southern accent.
In-Series Nickname: Jacob Black gives her the nickname "Nessie" because he thinks her full name, Renesmee Carlie Cullen, is a "mouthful". At first, Bella refuses to use this nickname because of the obvious allusion to the Loch-Ness Monster, but by the end of the series she eventually warms to it. Before long everyone thinks of her as Nessie.
Other nicknames include Ness (used by Charlie Swan and Jacob Black), Vanessa Wolfe (by Bella Swan), E.J. (meaning Edward Jacob; used by Bella Swan), Bebe Linda (used by Carmen) and Little Nudger (used by Bella Swan).
Wise Beyond Their Years: After she was born, Renesmee learns the vampire laws and limitations very quickly and understands their consequences. She can memorize perfectly anything she sees or experiences, and understands people without much problem. Bella comments that she is already more intelligent than most adults, and has better control over her thirst than any of them.
An ancient coven of vampires living in Volterra, Italy. They consider themselves the rulemakers of the vampire world and purveyors of the arts. They are a large group, headed by the Big Three: Aro, Caius and Marcus, and have many scouts and guards. They are considered the antithesis of the Cullens.
Humans Are Special: Although they tend to see humans only as food, and don't care much about their human servants, they do appreciate art, literature, and music. They also acknowledge that taking over the planet is impossible.
Large Ham: Aro in the movies. Michael Sheen clearly had too much fun playing him!
The first adversary encountered in the first book. They first started out as a small group of hunters and nomads who just lived to drink good blood. Things went from bad to worse when Bella and her rich blood came into the picture. James was offed in Twilight, followed by Laurent in New Moon, and then Victoria and her giant army of newborns in Eclipse.
Adaptational Attractiveness: James is described as being very unremarkable in appearance, but in the movie, he's played by this guy. It is worth mentioning here that Bella is the one doing the describing and next to her oh-so-gorgeous vampire boyfriend, everyone probably seems unremarkable in appearance.
Werewolves Wolf-like changelings of the series. They are members of the Quileute tribe and are trained to protect humans from vampires. Members include Sam Uley (alpha), Paul Lahote, Jared Cameron, Embry Call, Quil Ateara V, Seth and Leah Clearwater, and Jacob.
Blessed with Suck: Unfortunately, it can sometimes cause their injuries to heal too fast, which is why Jacob needs his bones to be re-broken over and over to prevent them from knitting in the wrong shape.
Hot-Blooded: Paul, though he settles down in Breaking Dawn after imprinting on Jacob's sister offscreen.
Important Haircut: If they have long hair, they chop it off after they start phasing because it means shorter fur as a wolf.
Nice Guy / Keet: Seth. Edward even mentions that his mind is one of the purest and kindest he's ever read.
Becomes less nice in Breaking Dawn for a little while, due to jumping on the Double Standard bandwagon against his sister, but thankfully, he (unlike most other characters) gets over it fairly quickly.
Theme Naming: Most of them have Old Testament names (Jacob, Seth, Leah, Sam, Paul, Rachel and Rebecca). 4 of them (Jacob, Seth, Emily and Paul) are named after Meyer's siblings.
Wife Husbandry: A bad side effect of imprinting, as Quil and Jacob learn. Jacob is initially slighty Squicked to think about this as it relates to Quil and Claire, but after he imprints on Renesmee, the process is detailed more; his primary concern is for her to be "safe and happy", and if they eventually hook up, well, that's just a bonus.
Defrosting Ice Queen: Thanks to having some time apart from Sam in the last book, Leah warms up to Jacob and becomes much happier and calmer than she used to be.
Double Standard: Leah is a bitch who is ruining the lives of everyone because she can't get over being dumped by her fiance for a girl he'd literally just met, and having to mentally listen to him hate her, with no way to escape. When Jacob is the same because Bella married her boyfriend instead of him, Sam (the fiance who dumped Leah) tells Leah to be nice to Jacob, because he's had a much rougher time than she has. And the girl Sam left Leah for was her own cousin, Emily, whom Leah was very close to, and when Emily told Sam to go back to Leah he snapped and mauled her face so badly that she bears horrific scars that everyone can see.
Stupid Sexy Flanders: In the epilogue for "New Moon", Leah complains that Jacob's feelings for Bella are making her dream about kissing Bella through their Psychic Link. Of course, some fans don't buy that explanation.
