"Me? Books and cleverness! There are more important things. Friendship and bravery and—oh, Harry, be careful!"

The (other) Best Friend of Harry Potter.

The Brightest Witch Of Her Age.

The last third of the series' resident trio, who serves as the superego and always has a smart solution. Like Ron, Harry meets her on the Hogwarts express on the first day of school, though they don't become friends until an incident involving a troll at Halloween. Throughout the books, Hermione serves as The Professor, being practically married to the library.

Nineteen years later, she's married to Ron and has two children, Rose and Hugo.

    open/close all folders 

  • Academic Alpha Bitch: At first in Harry Potter and the Philosopher's Stone, and even after her Character Development, she remains something of a know-it-all for the entire series — something that's hinted in Philosopher's Stone to be covering up for a number of personal insecurities regarding social awkwardness.
    • She spends most of her first scenes bragging about all the spells she's read up on in advance, and showing off in class.
    • In Order of the Phoenix in particular, she gets pretty testy once it's time to prepare for and take the O.W.L.S. and arrogantly dismisses Fred and George's joke shop products as rubbish with no real use despite the fact, as Ron points out, they're raking in money from them, though she later admits that some of their stuff is really impressive.
    • In addition, in Half-Blood Prince, she grows angry and jealous of Harry, who is outshining her by following instructions provided by the eponymous Prince in his textbook. When a problem comes up that the Prince can't help Harry with, she is extremely smug that he's not going to beat her on this one — until he takes a shortcut and does.
  • The Ace: Zig-zagged. She is one of the most skilled witches in the saga, but lacks the raw power and almost instinctual grasp that Harry has of some spells that Hermione can't perform. She is not much of a duelist either and her skill on a broom is rather subpar. Hermione's skill comes from her extreme hard work ethic rather than the raw talent that people like Dumbledore, Voldemort or even Harry have.
  • Action Girl: Eventually grows into this over the books/the films, and is already a full-fledged one by the seventh and final book.
  • Adaptational Attractiveness: Hermione is described as rather plain, but isn't in the films. In the earlier books, she had large buck teeth until she had them magically shrunk in Goblet of Fire, contributing to her becoming attractive; the films skip entirely the large teeth detail.note 
    • Hermione's trademark bushy hair is also left out of the movies from Prisoner of Azkaban onwards, allowing Emma Watson to wear her hair in its more natural state, sleek with a few curls towards the ends.note 
  • Adaptational Badass: While Hermione is plenty brave in the books (though prone to crack under stress for a while), the movies portray her as more of an on-the-spot Action Girl.
    • The first and possibly biggest example of this crosses over with Ron's first Adaptational Wimp moment. Near the end of the first movie and book, Harry, Ron, and Hermione land on Devil's Snare, a plant that will slowly throttle them. In the movie, Ron starts panicking really fast and it is only due to Hermione's level head and knowledge that the three escape unthrottled. In the book however, Hermione was the one who fell to pieces. It was only with Ron getting her to calm down and focus that she realizes what they need to do to escape. Presumably this change was made due to the fact that they removed Hermione's moment of limelight in the book, a logic puzzle involving potions which probably wouldn't have played very well on screen. However, this switch in characterizations basically stuck for the rest of the series.
  • Adaptational Intelligence: Downplayed, as Hermione is already the smartest of the trio in the books, but many of Ron's more insightful moments from the books are given to her in the films, making him look dumber in comparison. These include:
    • The fact that hearing voices isn't a good sign (Chamber of Secrets).
    • Explaining the definition if the insulting term 'Mudblood' (Chamber of Secrets).
    • In the second film, she also uses Dumbledore’s wise line from the first book "Fear of a name only increases fear of the thing itself".
  • Adaptational Nice Girl: In the books, Hermione is a Jerk with a Heart of Gold — while she means well, she tends to be somewhat insensitive (for instance, her first reaction to learning that Lavender's pet rabbit had died was to try to use the event to assert that Trelawney was a fraud, and later calls Firenze a horse). She is also rather snippy when she gets annoyed (and she is decently easy to annoy, especially when it comes to Ron). In the films, many of these moments (including the examples listed) are removed, often with the side effect of making Ron look worse. This is notable in the scene where Trelawney is fired. In the books, Hermione flat out states she doesn't care if Trelawney gets fired. But in the films, she looks genuinely sympathetic towards her.
  • Agent Scully: At least, she's hesitant to believe things that are seen as superstitious or unlikely according to the laws of the magical world. There's a reason that Rowling described Luna as the "Anti-Hermione." It's a subversion of the way this trope usually plays out, though, in that Luna is usually the one who is wrong and who grows to be more sceptical.
    • Her being an Agent Scully even causes her to Rage Quit her Divination Class.
    • This is taken to something of an extreme in Deathly Hallows, where she bluntly refuses to believe in the Deathly Hallows, despite having confronted... well, let's see, a guy with an Omnicidal Maniac stuck to the back of his head, a rock that grants immortality, a cursed diary that can communicate with people, a giant snake that petrifies her, Dementors, etc.
      • That is mostly because she refuses to believe in anything that violates Magic A Is Magic A and the fact is she's able to believe in the cloak and with prodding would probably have believed the Elder Wand, it was the stone she was having trouble with and it was hinted that was due to being afraid of thinking about dead people.
  • Ambiguously Related: She might be related to or descended from Hector Dagworth-Granger, founder of the Most Extraordinary Society of Potioneers.
  • And I Must Scream: Was one of the victims who gets petrified by Tom Riddle's Basilisk.
  • Animal Motifs: Otter (her Patronus).
  • Arbitrary Scepticism: Despite living in a world of magic, she is critical of Divination and doesn't believe in the existence of the Grim, a large black dog said to be an omen of death.
  • Author Avatar: She is, by J. K. Rowling's own admission, an exaggeration of herself when she was younger. Rowling says she was a bit of an Insufferable Genius in her younger days but gradually mellowed out, much as Hermione does over the course of the series (this may be why, of all the young performers in the Potter movies, Rowling is closest to Emma Watson).
  • Aw, Look! They Really Do Love Each Other: With Ron. They constantly argued as children to hide their mutual attraction, but would come to one another's defence whenever the other was threatened and/or insulted.
  • Babies Ever After: Has two children (a daughter and a son) with Ron by their adulthood.
  • Badass Bookworm: Hermione is a notable example, being a know-it-all bookworm whose studies, combined with her significant innate talent grant her significant magical ability. She comes into her own in the last book, where nothing would have gotten done without her hyper-organization and constant vigilance. In the films, she even punches Malfoy in the face, though it's only a slap in the books.
  • Belligerent Sexual Tension: With Ron though it became noticeable starting in Book 4. The two argue and clash constantly due to their differing views and insecurities, but they very clearly care about one another and in fact, one of the motivating factors behind their aggression toward one another is jealousy.
  • Berserk Button: Hermione does not like being told that she's not good enough to excel at something, even if it's something she doesn't have an interest in. When Ron suggests that Professor Trelawney may be accurate in saying that Hermione lacks the "aura" for Divination she immediately ends the discussion and furiously storms off. This is a result of her insecurities and need to prove herself, likely due to her status as a Muggle-born.
  • Beware the Nice Ones: As Ron lampshades, Hermione can be rather "scary." While usually pleasant and law-abiding, if you cross her, she'll gladly use her vast knowledge of spells to demonstrate why crossing her is a bad idea.
    • When she found out that the Weasley Twins were giving their joke sweets to first years, she threatened them with writing to their mother. The twins immediately complied, an act which had never been seen before or since (though, granted, that had a lot to do with the nature of the threat).
    • Her humour can be quite cutting when she wants it to be.
    • She put a jinx on the Dumbledore's Army list to give anyone who ratted them out huge purple pimples on their face spelling out the word "sneak".
    • Weaponized birds.
    • She deliberately chose a date to the Christmas Party that would annoy Ron. And when Parvati commented that Hermione "liked her Quidditch players," Hermione corrected her, saying she only liked "really good Quidditch players", leaving Harry to ponder the depths girls would go to get revenge. For context, Ron was by this point the Gryffindor Keeper.
    • She set Snape's robes on fire when she was twelve. Granted, it was because she thought that he had jinxed Harry’s broom, and while trying to reach Snape, she accidentally knocked over the real culprit, Professor Quirrell.
    • She brewed an illegal potion in the bathroom, and came up with a plan that involved drugging Crabbe and Goyle and stuffing them in a closet so Harry and Ron could impersonate them to interrogate Malfoy.
    • She slapped Malfoy in the face in the third book (punched in the film). He definitely deserved it, but it's still pretty surprising given that Hermione usually just brushed off rude comments and encourages Ron and Harry to do the same.
    • She kept Rita Skeeter in beetle form in a jar for a year, then blackmailed her into telling Harry's story by threatening her with Azkaban if she didn't.
    • She led Umbridge in the Forbidden Forest hoping to get her in trouble with the Centaurs.
    • She modified her parents memories to make them forget that she existed.
  • Book Smart: Hermione is very knowledgeable due to reading a lot.
  • Brainy Brunette: Hermione is incredibly smart, being described as the brightest of her age, and is brunette in the books.
  • Broken Ace: Her sometimes abrasive attitude masked deep insecurities and fear of failure, as personified by her Boggart. Hermione feels the need to prove herself, perhaps partly because of how many people in wizarding society looked down on Muggle-borns.
  • Bully Turned Buddy: While not a 'bully', per-say, she does antagonize Ron and Harry a few times through being a stickler for the rules and an Insufferable Genius; she and Ron in particular are initially rather abrasive toward each other. But when a mountain troll puts Hermione in danger, Ron and Harry help her fight it off, marking the beginning of their friendship. Through the rest of the series Hermione is a member of the team, and ends up marrying Ron at series' end.
  • Can't Take Criticism: She tends to react very defensively when her ideas or plans are criticized. Any criticism towards S.P.E.W. is a particularly sore subject, and when Ron makes a fairly benign comment about the quality of her knitted hats looking like "woolly bladders" she doesn't speak to him for the rest of the day. It mellows out throughout the series but she still retains some of her Insufferable Genius tendencies.
  • Cassandra Truth: She's suspicious of the book Harry begins using in Potions during Half-Blood Prince and rightfully so. Unfortunately, a combination of her pride and disbelief at Harry being more competent than her in the class leads both Harry and Ron to assume she's just jealous that she's no longer the top student.
  • Cat Girl: Was turned into one when she accidentally put a cat hair in her polyjuice potion.
  • Childhood Friend Romance: With Ron — met in their pre-teen years, became High-School Sweethearts, and married afterwards.
  • Child Prodigy: A budding genius from her first year. At Hogwarts, Hermione was usually the first to master any spell, and was capable of using spells beyond her educational level. She eventually grew into a teen genius.
  • Class Representative: She was a prefect in books 5 and 6. She also ended up administrating Harry's D.A. class.
  • Clingy Jealous Girl: One of her similar aspects with Ron is just how venomous she can be with her jealousy/envy when it comes to Ron and romantic relations. While Ron's is a bit more obvious, looking back with the revelation they end up together makes some of these moments much more obvious. In Goblet of Fire, she's furious when Fleur thanks Ron for saving her sister Gabrielle by kissing him on the cheeks, and later on she scowls when Fleur smiles at Ron for complimenting her improved English. In Half-Blood Prince, when Ron starts dating Lavender, Hermione attacks him with a flock of birds, which leaves his hands and forearms bearing scratches and cuts for several weeks afterward.
  • The Cobbler's Children Have No Shoes: Isn't it ironic for the child of two dentists to have such a bad case of buck teeth at the age of eleven-going-on-twelve?note  Granted, she's said to have taken care of the problem herself by the Yule Ball, but still.
  • Condescending Compassion: Her treatment of House Elves is at least initially very much this, and presented as such. Upon learning about their place in the wizarding world, she immediately concludes they're brainwashed slaves and works to free them and grant them full human rights. This is probably not helped by the fact that the first House Elf she encounters, Dobby, doesn't conform to the rest of his species' Blue-and-Orange Morality makes them eager to serve humans, and they're offended by such notions as "freedom" and "payment", considering their hard work being appreciated a perfect reward. They like working for kind, understanding humans better than mistreatment, but they still (with only one exception that we see) prefer mistreatment to freedom, to the point where they literally consider it a Fate Worse than Death. Hermione, believing that she knows what's best for them and that they'll like freedom "once they've got a taste of it," attempts to trick them into freeing themselves. They do not take it well. Dumbledore, by contrast, treats them kindly and respectfully and gladly agrees to pay the one House Elf who asks for it (Dobby), but does not suggest freeing the majority who don't desire it.
    • Thankfully, though, she comes to understand elves a bit better, being the only person other than Dumbledore to have an accurate measure of Kreacher's character in Order of the Phoenix, and explains how the apparent inconsistencies in his thinking (being pro-Pureblood supremacy despite Voldemort's vile treatment of him and his beloved master Regulus turning against Voldemort) make sense from his perspective in Deathly Hallows.
  • Cool Big Sis:
    • Although they're in the same year, she seems to fulfil this role in regards to Neville, helping him when he falls behind in classes he's not good at. When Snape tries to make Neville test his improperly-prepared Shrinking Solution on his pet toad Trevor, it's Hermione who helps him fix it.
    • She fulfils this role towards Ginny as well, giving her advice on topics such as her feelings towards Harry.
  • Cowardly Lion: Downplayed example. Whenever situations go sideways, Hermione tends to be the first one to panic. It's one of her major character growths that in later books she is able to do quick thinking under pressure to get everyone out alive considering in the first book she had to be reminded by Ron that she could perform magic when they were trapped by the devil's snare.
  • Crazy-Prepared: Especially for the road trip in Book 7.
  • Curtains Match the Windows: Matching brown hair and eyes.
  • Dark Is Not Evil: Hermione was not known for her ability to cast Dark magic and the extent of her ability within this magical discipline is truly unknown (however, one would assume given her borderline genius status that she was no slouch). Still, she must have had some ability as she was able to come up with a very sophisticated jinx that would deform the face of anyone who betrayed the D.A.. She was also able to successfully cast a Stinging Hex at a moment's notice in her fourth year. She was also able to cast the Full-Body-Bind Curse in her first year and the Jelly-Legs Jinx in her sixth.
  • Deadpan Snarker: Not nearly as often as Harry, but she has her moments. She tends to do this when she gets angry or stressed.
    Hermione: Rack your brains, Ron, that should only take a couple of seconds!
  • Defrosting Ice Queen: In the first third or so of book one.
  • Disproportionate Retribution:
    • If you fuck with her in a dream, you'd better wake up and apologise. Just ask Marietta Edgecombe. To elaborate: Hermione had booby-trapped the Dumbledore's Army member list so anyone who betrayed them got 'Sneak' written across their face in acne. The Disproportionate bit comes in when the next book implies Marietta still has those pimples the next year and we're not told if Hermione ever lifts the jinx, which as Cho pointed out, she should have told everyone about from the start instead of essentially tricking her classmates into signing a contract without fully explaining the terms.
    • She cheerfully traps Rita Skeeter in a tiny, unbreakable jar and blackmails her into agreeing to never publish another story in book 4. Hermione lifts that sanction in book 5, but not before blackmailing Skeeter a second time. Sure, Skeeter was deeply unpleasant, and nearly destroyed Hagrid's life for the sake of a story, as well as making a fair mess of Hermione's own, but she's not someone to cross.
  • Dude Magnet: After having her formerly prominent front teeth shrunk after being hit by Malfoy's deflected curse, growing into her features a little, and becoming rather more confident, she becomes this. Namely, she became the "thing missed most" in the Triwizard Tournament for Quidditch superstar, Viktor Krum. Two years later, Hermione got the (unwelcome) attention of Cormac McLaggen. Then, there's Ron Weasley.
  • Fatal Flaw:
    • Pride. Hermione, due to her good marks and skill at casting, is extremely prideful. Everything has to be her way and no other. When every evidence pointed towards Croonkshanks killing Scabbers she went in full Never My Fault. Or when Harry found out the Half-Blood Prince's book contained better instructions to make the potions, she started to suspect there had to be something off about it, and practically gloated to Harry's face after the Sectumsempra incident that almost resulted in Draco being killed.
    • Lack of Empathy: VERY Downplayed, but Hermione at several points is quite insensitive. When a grieving Lavender is crying over the Death of her bunny, she is more interested in explaining to her why Divination is stupid. Also she is very bad at guessing people emotional state and creates problems with that. Plus she tends to project her insecurities into others and be unnecesarily harsh (Specially to Ron)
  • Fantastic Slurs: Is on the receiving end of this, as she is called a "Mudblood" by Malfoy or other pure blood-supremacists.
  • Fire-Forged Friends: Her time at Hogwarts would have turned out quite different if not for her troll adventure.
  • First Love: To Ron. Even though Lavender Brown was his first girlfriend, he has always carried a torch for Hermione.
  • Flat-Earth Atheist: Despite the fact that she lives in a world of magic, she still attempts to act as a rational sceptic; particularly in her derisive attitude toward divination or Luna Lovegood's cryptozoology.
  • For Great Justice: As Hermione gets older, she becomes an advocate for muggle-born wizards and elves. Though she means well, she’s sometimes misguided and is unintentionally rude to the creatures on whose behalf she’s speaking. In fact, the Hogwarts house elves end up refusing to clean Gryffindor Tower because Hermione would hide articles of clothing for them to find and were insulted that she was trying to trick them.
  • Four-Temperament Ensemble: Melancholic — honest, trustworthy, loyal, skeptical and perfectionist.
  • Future Badass: Is a wanted criminal leading The Resistance in an alternate timeline where Harry's dead and Voldemort won.

  • Genre Blindness: Of the three main characters, Hermione suffers the most from this, despite having read numerous books of magic. You would think by now she would realize that anything can and possibly will happen in the world she lives in. She is the most sceptical of the trio when it comes to the more mysterious aspects of the Wizarding World that are mostly unsubstantiated. And when they are, she'll point out why it still doesn't make sense. She dismissed the Deathly Hallows mostly because the way they found out about them was less than reliable AND the idea behind the Resurrection Stone doesn't make sense in a world where All Deaths Final. There's also her attempts with SPEW, where she believes she's a great revolutionary who will free all of the elves, despite them being offended by and rejecting her efforts. In fairness, the Resurrection Stone is a completely unique artifact which most witches and wizards were sceptical of, and she does eventually grow out of her Condescending Compassion towards elves, demonstrating she understands their Blue-and-Orange Morality fairly well in Deathly Hallows. Indeed, she maanges to help fix many of the problems of Wizard/Magical Creature relations, but only after she's grown out of her previous mindset.
  • Go-Getter Girl: Hermione always seeks to be tops in her classes and impress her teachers. And yet, she (mostly) stays well-grounded throughout it all.
  • Good Is Not Soft: She’s somewhat prone to insult humour.
  • Good with Numbers: Arithmancy was Hermione's favourite subject and, considering she was one of the few people to take this subject, she must have skill in this field, too. She earned an 'Outstanding' O.W.L and took the subject to N.E.W.T.-level.
  • Goofy Buckteeth: She has buckteeth in the books. While she's skilled at all sorts of magic and incredibly intelligent, she is often not taken seriously in her early years as she can be a know-it-all. Getting rid of her buckteeth midway through the series comes at around the same time she starts being taken more seriously as both a talented witch and a love interest.
  • Handwriting as Characterization: Hermione's handwriting is always neat, per her characterization as an overachieving perfectionist.
  • Happily Married: The Cursed Child shows that while she and Ron may still get into arguments, they have a gentle, loving marriage with Ron being the romantic of the two.
  • The Heart: Peacekeeper for the three.
  • Heroic Sacrifice: In The Cursed Child, in the Voldemort Victorious timeline, she and Ron delay some Dementors so Scorpius and Snape can escape.
  • Heterosexual Life-Partners: She forms close friendships, lasting in their adult years, with Ginny and Luna.
  • High School Sweet Hearts: With Ron, as they are married by the epilogue, though Rowling says their differing temperments would have necessitated marriage counselling at some point.
  • Hot Witch: In the movies (due to Emma Watson going from 'cute' to 'beautiful'), and in the latter half of the 7 books (from the Yule Ball in book 4 onwards). No adverse mention is ever really made of Hermione's looks in the films, while in the books, it comes across as her focusing on schoolwork and not bothering to spend time on needless beautification (although in book 4, she does have Madame Pomphrey shrink her front teeth so that she's no longer buck-toothed).
  • Inferiority Superiority Complex: In the first book, Hermione acts like a total know-it-all to mask her insecurity for being a fairly plain and socially awkward muggle-born. It decreases throughout the series as Hermione quickly gains confidence in herself and her abilities, though she does relapse back into it during the sixth year when Harry starts to surpass her in Potions thanks to the Prince's textbook.
  • Informed Ability: Hermione is considered the "brightest witch of her age," but compared to teen geniuses from other eras (the Marauders and Snape, Riddle, and Dumbledore), she fails to measure up. She never achieves feats of magic comparable to the the Marauder's Map and the animagi transformation, Snape's potions improvements and invented spells, or Riddle's horcruxes, and unlike Dumbledore, never publishes any papers or wins any academic awards. Percy and Barty Crouch Jr. both earn 12 OWLS to her 10, and Fred and George, who are repeatedly derided for their poor academic performance, invent products for their joke shop that require complex, never-before-seen magic that Hermione is surprised by. Hermione is obviously smart, but she's not a prodigy.
  • In-Series Nickname: Her unusual name attracts these from those unskilled with English, notably Viktor Krum and Grawp, and many non-UK readers who initially pronounced her name much like Krum did.
  • Insistent Terminology: She gets rather snippy when people refer to her "Society for the Promotion of Elvish Welfare" by its acronym. The name is even better in Dutch: "Stichting Huiself voor Inburgering en Tolerantie" (society house-elf for naturalizing and tolerance).
  • Insufferable Genius: Sometimes ends up as this, especially in Philosopher's Stone. Snape likes to criticize her for it. Most people, including Ron and Harry, tend to tolerate it.
    Severus Snape: Five more points from Gryffindor for being an insufferable know-it-all.
    It was a mark of how much the class loathed Snape that they were all glaring at him, because every one of them had called Hermione a know-it-all at least once, and Ron, who told Hermione she was a know-it-all at least twice a week, said loudly, "You asked us a question and she knows the answer! Why ask if you don't want to be told?"
  • Intelligence Equals Isolation: Played straight at the beginning of the first book, but subverted later, when it becomes clear that Hermione is not particularly shy.
  • Invisible Parents: In contrast to Ron and Harry, whose unusually large and (ahem) "unusually small" families are important plot points, Hermione's comparatively normal family is rarely mentioned and appear "in person" very rarely (in Book Three and Movies Two and Seven). For those who are wondering, they're Muggle dentists. How invisible are they? We have yet to be told their first names. Even nowadays they're still referred to as "Mr. and Mrs. Granger". The closest thing we get to names are "Wendell and Monica Wilkins," in the final book; their memory-modified pseudonyms. It is possible that Hermione gets her middle name "Jean" from Mrs. Granger's first name, like other HPverse characters, including Harry James Potter and Ginevra Molly Weasley.
  • Jack of All Stats: Being The Smart Girl of the Trio, Hermione is talented and knowledgeable in nearly all subjects, except Defence Against the Dark Arts, which Harry is best at. And even with Defence Against the Dark Arts, it's The B Grade (she gets an "Exceeds Expectations" instead of the "Outstanding" she got with everything else), not a major failing.
  • Jerkass Has a Point: Hermione may be an Insufferable Genius at times, but she makes a lot of mature points throughout the franchise.
    • During a class with Ron, she does show him the right way to pronounce and apply the levitation spell. Snobby as she may have been, she was right.
    • While reporting Harry's broom to be confiscated without first telling Harry may have been over-stepping her boundaries, her reasoning wasn't — stating the broom could've been hexed by Sirius Black, who they thought at the time to be dangerous. Hagrid even points this out during his calling out of both Harry and Ron for their treatment of her in Book 3.
    • During her and Ron's fight after the Yule Ball, the former makes it clear that the latter should've had the courage to ask her out before Viktor. And it's not untrue, as Ron spent the majority of the Ball seething in jealousy over Hermione being with Viktor, and his prior attempts to ask out Hermione was rude and insensitive.
    • In the final book, she gives Ron a well deserved shouting for first abandoning her and Harry during the Horcrux Hunt and then showing up again seemingly without a care in the world (as it turns out, he'd been trying to find them since the moment he'd left, after having a My God, What Have I Done? moment, but she had no reason to know that at the time).
  • Jerk with a Heart of Gold: While Hermione can come across as bossy and intellectually snobby, she usually means well and is compassionate towards those in need (such as Neville).
  • Junior Counterpart: She has been noted to be uncannily similar in personality and ability to Professor McGonagall, with both being intelligent, logical and book-smart. When Harry and Ron baulk at the idea of using Polyjuice Potion to impersonate Crabbe and Goyle in Chamber of Secrets, Hermione gets a "steely glint in her eye not unlike the one Professor McGonagall sometimes had."
  • Kindhearted Cat Lover: In Book 3, Hermione became the owner of Half-Kneazle/Half-Cat Crookshanks, who won Hermione's heart the first moment she saw him.
  • The Lancer: Takes this role in the films while it's Ron in the books. One such example of her taking greater inititative is when she comes up with the idea for escaping Gringotts bank on a dragon when it's Harry's idea in the books.
  • Letting Her Hair Down: An Inverted Trope, at the Yule Ball in book four. She uses Sleekeazy's Hair Potion to style her normally messy hair into an elegant bun.
  • Like Brother and Sister: How Harry sees her. Harry never demonstrates any romantic interest in Hermione, and vice versa.
  • Like Parent, Like Spouse: Her relationship with Ron is very similar to the relationship between Ron's parents. Lampshaded multiple times, when the narration — which is from Harry's perspective — describes Hermione as acting very much like Molly Weasley. In Order of the Phoenix, the narration even points out that Ron and Hermione's bickering is strongly reminiscent of Molly and Arthur's own bickering.
  • Little Miss Snarker: On occasion, especially when someone breaks the rules without reason.
  • Living Emotional Crutch: To Harry. Along with Ron, Harry leans on Hermione not only for dangerous adventures, but for emotional support. And without her (or Ron), Harry wouldn't have a will to live.
  • Love Makes You Dumb: Her Precocious Crush on Gilderoy Lockhart in the second book blinds her to the fact the man is clearly a fraud who is not as skilled with magic as he claims he is, something Harry and Ron caught onto after just one class with him.
  • Luke, I Might Be Your Father: Slughorn mentions a potioneer named Hector Dagworth-Granger and wonders if Hermione might be a distant relative of his.

  • Mage Born of Muggles: She's the most important muggle-born character in the series. She's subjected to a lot of Fantastic Racism, especially from Draco Malfoy, because of it.
  • The Maiden Name Debate: Hermione keeps her name after marriage, and notably their children have a hyphenated surname.
  • Messy Hair: She tells Harry that taming it is too much bother.
  • Mirror Character: Upon closer examination, she has a surprising amount in common with Ron, personality-wise.
    • Both of them are defined by their insecurity in relations to wanting to stand out to their peers (compared to Harry, whose insecurities is more on fitting in). This is especially the case when it comes to their mutual attraction (though with Ron, we know it is because he feels he's not good enough for her though we've yet to see Hermione's thoughts on her feelings with Ron.)
    • Furthermore, both of them are very much the jealous types and are not willing to admit to their emotions about it. Heck, they are both prone to being very petty about it (though given Too Clever by Half with Hermione, her instances could be considered worse than Ron's, whose bouts are by impulse, which Harry even lampshades in his thoughts.)
    • Fascinatingly, they are also both very empathetic yet also prone to being insensitive at the same time. While Hermione is the one who can better relate to people in emotions, Ron's the more emotive one who would get angry or happy alongside someone. At the same time, Ron is often chided for his insensitivity, sometimes by Hermione who does similar actions, but is not called on it. And often, said insensitivity cause problems with each other (Hermione gets angry at Ron's seeming insensitivity to her yet she often makes comments or does things that make Ron feel worse.) Furthermore, Hermione's insensitivity appears to also be connected to her Condescending Compassion.
  • Moe Couplet: Hermione is a magical genius, except when it comes to dealing with actual dark wizards, which is Harry's specialty his life being basically a long series of fighting dark wizards. Hermione, however overcomes this problem gradually, eventually becoming a damn good fighter towards the end of the series. When it comes to personality, Harry is selfless to an annoying degree even when personal friends are not involved, while Hermione focuses on immediate gain and loss to her close friends (especially when it comes to grades!). While these traits alone would get kind of annoying, together they play off each other quite well.
  • Motor Mouth: Mainly in the first books, Hermione tends to go on about herself and technical subjects while disregarding the interest of those around her. Her interactions with Ron and Harry help her outgrow this pretty quickly.
  • Ms. Exposition: Due to being such a brain, Hermione often figures out and explains crucial plot points to her Book Dumb friends. Lampshaded when Hermione asks Harry and Ron if they're ever going to read Hogwarts: A History — Ron replies, "Why should we when we've got you to explain it all?" Rowling has said in interviews that her default characters for exposition-giving are always Dumbledore and Hermione — Dumbledore because he's the wise old wizard, Hermione because any fact can be explained by her having found it in a book somewhere. Averted in Book 7 when it is Harry, not Hermione, who remembers the name of the author of A History of Magic, despite (or possibly because of) the fact that Harry never read it, yet was told repeatedly about it.note  This might say something about Hermione's retention of "important" information, such as the contents being more important to her than the author. Also subverted in book seven, when Ron knows more about the Deathly Hallows than Hermione. It's justified because they're a fairy tale he grew up with, as the only member of the Trio to be raised by wizards.
  • My Beloved Smother: Implied to become one. In the movie version, she frets over Rose having everything she needs.
  • Nerds Are Sexy: Grows into this trope in the later films and books.
  • Nerds Love Tough Schoolwork: Deconstructed in the third book, when she takes so many classes she ends up having to resort to time travel to get to them all. The sheer amount of homework from her combined classes proves to be too much even for her, causing her no end of stress. She switches back to a normal schedule by the next book.
    ...Even so, [Harry] wasn’t showing the strain nearly as much as Hermione, whose immense workload finally seemed to be getting to her. Every night, without fail, Hermione was to be seen in a corner of the common room, several tables spread with books, Arithmancy charts, rune dictionaries, diagrams of Muggles lifting heavy objects, and file upon file of extensive notes; she barely spoke to anybody and snapped when she was interrupted.
  • Nice Girl: Yes, she is flawed with her bossiness, but she is a kind, hard-working, loyal friend.
  • Not So Above It All:
    • Hermione had a crush on Gilderoy Lockhart and actually bought his publicity, despite Ron and Harry seeing him as an obvious fraud. Ron never misses a chance to remind Hermione about this.
    • Though she'll smile or laugh often, Hermione's usual response to most of Harry and Ron's more lowbrow jokes is mild disapprovement. In Goblet of Fire, however, The Trio hear an elderly wizard named Archie complain about possibly wearing pants, saying that he likes "a healthy breeze round my privates". This gives Hermione such a serious case of giggling that she has to leave the area temporarily.
    • Despite campaigning for the rights of oppressed groups like muggle-borns and house elves, she sometimes shows signs of Fantastic Racism herself, like when she derogatorily referred to Firenze as a horse after he became Hogwarts' new Divination teacher.
    • She's called Harry and Ron out for their impulsiveness since the first book, but her "S.P.E.W." campaign in Goblet of Fire demonstrates that she can also get ahead of herself and act without thinking things through.
    • She is rude to Luna Lovegood, mocking her beliefs and using the nickname that Luna's bullies devised for her ("Loony" Lovegood), even though Hermione was herself bullied before Harry and Ron befriended her and even afterwards.
    • She confunds Ron's main rival for keeper during the Quidditch try-outs, but is still outraged when she thinks Harry gave Ron some felix felicis before a match. She tries to justify her actions on the grounds a trial is not the same as an actual match with rules, but still.
    • In the finale of Book 7, despite claiming that of the Deathly Hallows, she would choose the Cloak of Invisibility, Harry notes that she, and Ron, both looked at the powerful Elder Wand covetously and with reverence.
  • One of the Boys: She spends more time hanging out with Harry and Ron than with, say, Parvati and Lavender.
  • One True Love: Played with. In Cursed Child it's revealed that she doesn't get married to Ron in two futures created by Scorpius and Albus' interference with time, in one case because of a small reason (the Yule Ball going differently), while, for example Harry and Ginny's relationship still happens (despite, logically, Harry's life should also look much different in details due to Ron and Hermione's different relationship). Still, in both of those futures their mutual attraction is revived at instant by Albus or Scorpius mentioning their marriage in the main timeline. And in one of those futures Ron is married to another woman. And no (shown) alternate timeline has her end up with Harry.
  • O.O.C. Is Serious Business:
    • When Hermione advocates breaking the rules, you know it's serious. Lampshaded in the Chamber of Secrets book.
      Ron: I never expected you to persuade us to break school rules!
    • Lampshaded in the Order of the Phoenix movie, too.
      Hermione: This is sort of exciting, isn't it? Breaking the rules!
      Ron: Who are you and what have you done with Hermione Granger?
    • Throughout the series, of the primary trio Hermione is generally shown to be the most levelheaded, pragmatic and in control, often reigning in the brash tendencies of Harry and Ron. In Deathly Hallows it's clear that Ron abandoning them affects Hermione deeply but when he returns she well and truly flips out. She physically attacks Ron to the extent that Harry has to use a Shield Charm to restrain her and is astonished, having never seen Hermione like this and describing her as looking "demented."
  • Open Mouth, Insert Foot: She’s an intelligent young lady, but has been shown to not think before she speaks. The best example of this is in Order of the Phoenix when Luna voices her support for Harry and Hermione somewhat condescendingly dismisses The Quibbler as a load of nonsense. Luna coldly says that her father’s the editor. Harry angrily tells Hermione to stop insulting everyone on his side.
  • Opposites Attract: The serious, go-getter witch fell in love with the funny, laid-back wizard (Ron). Though as noted above, they're not all that different...
  • Playing with Fire: In the first two books she conjures blue fires that can be carried around in jars on cold days, burn the Devil's Snare and boil the polyjuice potion in a toilet bowl.
  • Plucky Girl: A brave member of the Golden Trio and Magical Girl Warrior extraordinaire.
  • Precocious Crush: As a pre-teen, Hermione had a crush on Gilderoy Lockhart during Chamber of Secrets, to the point of outlining all his lessons on her schedule in little hearts and keeping a get-well card from him under her pillow.
  • Pride:
    • This is Hermione's Fatal Flaw in Prisoner of Azkaban. She signs up for every course believing she can do all the extracurriculars, and nearly goes insane from all the work she has to do. She dismisses Ron's worries about her cat going after Scabbers and only apologizes when Ron promises to help her with Buckbeak's case. Then she tells McGonagall about the Firebolt that Harry receives on Christmas without telling Harry about her worries first, which lead to Ron and Harry calling her out since Harry needs a new broom to play Quidditch and since he's Sirius Black's main target he ought to know if a nice present will try to kill him. By the end of the book Character Development sets in; she drops two of her classes to have a better schedule, admits she was wrong about the Firebolt when McGonagall can't find any jinxes on it, and tries to shoo Crookshanks away from Scabbers near the Whomping Willow.
    • It kicks back again in Half-Blood Prince. First, she's disappointed to see that she got an "Exceed Expectations" in Defence Against the Dark Arts, and later, when Harry starts outshinning her in Potions she feels threatened and is quick to call him out on his "cheating", and even when Harry offers to share the Prince's notes with her, she refuses to accept them.
  • Quirky Curls: Especially in the movies.
  • Race Lift: Has been played by black actresses in every run of Harry Potter and the Cursed Child. However, JKR has observed that Hermione's skin tone is never mentioned in the books (despite there being an instance of Hermione's "white face" being mentioned), so this only applies in comparison to the films and the cover illustrations.
  • Randomly Gifted: Hermione is a Muggle-born witch, meaning she was born to two non-magical parents. She is frequently held up by other characters as the prime example of blood purity not being the deciding factor in what makes a skilled witch or wizard.
  • Reasonable Authority Figure: As a prefect she adheres to rules and regulations, confiscating banned items and generally having a much better handle on prefect responsibilities than Ron. She even finds a way to temper Fred and George's antics once they cross a line by testing their products on first years by threatening to write to Mrs. Weasley.
  • Red Oni, Blue Oni: The level-headed and logical blue to Harry and Ron's red.
  • Relationship Upgrade: She and Ron become Fire-Forged Friends in the first book. By the time of the third book, the beginnings of their long and complicated Belligerent Sexual Tension is born. By the seventh book, they share an Big Damn Kiss that seals them as an Official Couple. And the epilogue shows them Happily Married with a daughter and son.
  • Reset-Button Suicide Mission: In The Cursed Child, the she and Ron from Voldemort's Bad Future sacrifice themselves to Dementors knowing that Scorpius will undo it.
  • Right for the Wrong Reasons:
    • When Harry anonymously receives a very expensive Firebolt as a Christmas gift in Prisoner of Azkaban Hermione is convinced that Sirius Black sent it to him and sabotaged it to kill him. Sirius did send it, but Sirius was Good All Along and genuinely intended it as a gift to his godson.
    • In Half-Blood Prince, she was convinced that there had to be something sinister about the Prince's book, mostly due to being jealous of Harry overshadowing her in Potions. Then the Sectumsempra incident happened.
  • Running Gag:
    • Hermione becoming exasperated with people for not having read Hogwarts: A History. Lampshaded by Ron, who says that they don't need to read it because she'll just tell them anyway.
    • Her advocacy of freedom for house-elves.
    • Whenever she gets an idea, she tends to run off to test her theory or put it into practice without explaining anything to Harry or Ron. Lampshaded by Ron in Order of the Phoenix.
      "I hate it when she does that. Would it kill her to tell us what she's up to for once? It'd take her about ten more seconds..."

  • Sadistic Teacher: In the alternate timeline in Harry Potter and the Cursed Child, where she and Ron never got together, she's Hogwarts' Defence Against The Dark Arts teacher and happily docks house points.
  • Sesquipedalian Loquaciousness: Almost always in the movies.
  • She Cleans Up Nicely: Bushy-haired, buck-toothed Hermione is usually too concerned with schoolwork to worry about her looks too much. But when she does have an occasion to dress up, she's a stunner.
    • In Harry Potter and the Goblet of Fire, Harry doesn't recognize her at the Yule Ball at first, noting blandly that Krum was accompanied by “a pretty girl in blue robes that Harry didn’t know.” The movie plays it straight (as nobody could fail to recognise Emma Watson) and Hermione descends the stairs while Harry and Ron look on agog.
    • Noted again at Bill and Fleur's wedding, where she's noted for being very beautiful, this time in floaty lilac dress robes.
  • She Is All Grown Up: The books imply that she's rather plain as a child, with bushy hair and buck teeth, but as she grows older and has her teeth fixed by magic, she becomes at least pretty attractive. Certainly, more and more boys seem to be interested in her…
  • She Is Not My Girlfriend: Harry says this about her. See also Like Brother and Sister, above.
  • Shipper on Deck: Towards Harry and Ginny.
  • Shorter Means Smarter: Hermione is the smartest of the trio and it's heavily implied that she remains the shortest of them, at least in the books, as Ron is notably tall for his age from the start, while Harry hits a growth spurt after Goblet of Fire.
  • Single Woman Seeks Good Man:
    • Hermione has a long-running Belligerent Sexual Tension-style attraction to fundamentally good guy Ron Weasley. The thing that finally pushes her to kiss him senseless? It's when Ron realizes in a panic that the House Elves are unprotected during the Battle of Hogwarts. The welfare of House Elves has long been a moral cause close to Hermione's heart, and one that had opened her up to general ridicule in previous books (especially from Ron). Although it's worth pointing out there's a difference between forcing unwanted freedom on them and trying to make sure they don't get killed.
    • Hermione's brief love interest Viktor Krum, although he's introduced as an intimidating world-class athlete from a rival school, turns out to be a pretty nice guy.
  • Sixth Ranger: Fills this role in the first book, since she joins Harry and Ron halfway. At first, her know-it-all behaviour put her at odds with Harry and Ron, but the battle with the mountain troll caused her to join Harry and Ron, finally forming the well known trio.
  • Skewed Priorities: Provides the page quote where apparently getting expelled is worse than getting killed. Pops up two years later when she is unable to face her Boggartnote  which is Professor McGonagall telling her she failed all her classes. The films really make this one of her defining traits. In the third film, when Harry illegally does magic outside school she says he was lucky not to be expelled — Harry replies he was lucky not to be arrested. And in the seventh, when they have just narrowly escaped the Death Eaters twice she laments that they didn't celebrate Harry's birthday.
  • Skilled, but Naive: In contrast to Harry, who was Taught by Experience, she has an encyclopaedic arsenal of magic but tends to perform awkwardly in fast-paced practical combat. However, she gradually grows out of this, becoming a very good fighter in the later books, in which she is able to defeat various dark wizards in combat.
  • Slap-Slap-Kiss: With Ron.
  • Slipknot Ponytail: Her hair, after the Yule Ball, is described as having come undone from its updo as she's arguing with Ron at the end of the night.
  • The Smart Girl: The cleverest witch in her year at Hogwarts, and quite possibly the cleverest witch, period. She displays magic in her fifth year that seventh-year students consider extremely advanced — and she learned it as an offhand "oh, I was just studying ahead" thing. We're never told just how she stacks up with the rest of the wizarding world, but she's probably right up there.
  • Smug Snake: When the Insufferable Genius aspect goes too far she can drift into this, especially in the first book.
  • Soapbox Sadie: On the subject of house elves, Hermione is very passionate and over-the-top in her campaign to get them fair wages and better treatment. Often despite the lack of support from the house elves themselves.
  • Speak Ill of the Dead: Towards Sirius to Harry — while it's not with any malice, and she's making a very important point, it understandably rankles. "Sirius was horrible to Kreacher... I've said all along that wizards would pay for how they treat house elves. Well, Voldemort did... and so did Sirius."
  • The Spock: The most logical and rational (mostly) of the trio.
  • Sudden Name Change: A meta example: Rowling's statements had long established that her middle name was "Jane," which the fifth book also established as Umbridge's middle name. The final book makes Hermione's middle name "Jean" instead. Rowling stated that she had changed her mind because she didn't want the heroine Hermione to share a middle name with the bad and sadistic Dolores Umbridge.
  • Sugar-and-Ice Personality: At least in book one, but becomes more Tsundere as the story goes on.
  • Surprise Slide Staircase: Uses the Glisseo spell to do this to avoid two Death Eaters during the Battle of Hogwarts.
  • Screw the Rules, I'm Doing What's Right!: Hermione will sometimes break the rules if she thinks the alternative would be more moral.
    • She lies to Mcgonagall to protect Harry and Ron after they save her from the troll.
    • She makes the polyjuice potion as she wants to prevent students from getting harmed.
    • She fully supports Dumbledore's army even though the Ministry would be firmly against it.
  • Team Mom: Sometimes tries to mother the boys, which is generally met with irritation from Harry and ambivalence from Ron, who is used to it. Indeed, Ron sometimes mothers her right back.
  • Tender Tears: As the token girl, she’s somewhat prone to crying.
  • Teen Genius: Harry even refers to her as "The brightest of our year." She gets 112% on an exam in her first year, and she even passes 3rd year Muggle Studies with 320%. Although, as Ron points out, she has a bit of a leg-up with that last one given her background.
  • Textile Work Is Feminine: As part of her crusade for house-elf rights, she knits elf-sized hats (albeit not very well, with Ron saying they look more like "woolly bladders") and leaves them around Gryffindor Tower in a bid to free the Hogwarts house-elves. She also makes a patchwork quilt as a Christmas gift for Kreacher.
  • To Be Lawful or Good: Hermione starts out as lawful (and consequently, friendless), but her adventures with Harry and Ron chip away at this. Her troll encounter pulls her sharply in the direction of good. This culminates with a tenure as head of magical law enforcement, likely so others don't have to choose.
  • Token Religious Teammate: It's subtly hinted that Hermione has some kind of spiritual and religious beliefs. For one thing she readily accepts and understands the concept of a soul that Ron and Harry have a little difficulty in understanding. Likewise, when she and Harry glimpse the grave of Harry's parents and find the "last thing is to be destroyed" phrase, she understands and explicates the meaning to Harry who literally didn't get it at all. As a Muggle-born, she may have grown up nominally (if not practicing) Christian or at least been familiar with its teachings, as opposed to her peers who grew up in the wizarding world, where religion does not seem to be important.
  • Took a Level in Badass: At least as far as her ability to stay calm under pressure goes. In Book 1, she was the first of the trio to crack under pressure and lose her mind to panic as seen with the Devil's Snare episode. By book 5, she's started being able to come up with plans under pressure, though they don't always go as planned such as her plan to deal with Umbrage when she had them hostage. She led Umbridge into the forbidden forest, but randomly taking a path nearly took them to Aragog's lair, and even though the centaurs she was trying to get the attention of did take care of Umbridge, they turned on Harry and Hermione moments later and nearly killed them. By book 7 however, she is able to do lots of quick thinking under pressure, and gets Harry and Ron out of multiple life or death situations.
  • Took a Level in Kindness:
    • In Philosopher's Stone, Hermione becomes friends with Harry and Ron after they save her from the troll.
    • In regards with Luna, Hermione eventually accepted their differences in magical creatures. The following year, they become the best of friends.
  • Town Girls: The Femme to Ginny's Butch and Luna's Neither.
  • Tragic Keepsake: Dumbledore bequeathed the original publication of The Tales of Beedle the Bard, written in runes, to Hermione. It contained a clue about the Deathly Hallows which led Hermione, Harry, and Ron to Xenophilius Lovegood, who told them about the legendary items. Later in life, Hermione translated the book into English and published her translation.
  • Tsundere: Played with and towards Ron. She's usually Sweet, but whenever Ron is... well, Ron, she will instantly go Harsh and snap at him out of worry for him. This becomes especially prevalent with each book/movie, to the point it's hard to tell whether she is Sweet or Harsh. This is lampshaded in Deathly Hallows Part One.
    Harry: You're not still mad at him (Ron), are you?
    Hermione: I'm always mad at him.
  • Unbuilt Trope: On account of her higher profile in the adaptations and reputation as a feminist icon by millennials it's often lost that the original Hermione is not quite as advantaged and perfect as later fans imagine her to be:
    • It's lost out that in Book 1, Hermione was rescued by Ron and Harry from the Troll while she was entirely caught off guard, and that in the finale, the Devil's Snare scene was changed significantly. In the books, it's Hermione who panics not knowing about how to solve the Devil's Snare, noting that there's no Wood to light a fire, while Ron yells out, "Are you a witch or not?". In Book 5, during the vast duel with the Death Eaters, she gets knocked out by Dolohov with a dangerous curse, and combat is her main weakness, while Harry and Ron constantly improve, she never becomes much of a duelist herself. Her main skills are organizing and logistics (as in the DA, and the camping equipment for the Horcrux trip).
    • Likewise, Hermione does not quite do as well in school (getting 10 OWLS when the usual mark of genius is 12, which was achieved by Barty Crouch Jr. and Percy). She has a Fatal Flaw of Arbitrary Scepticism—relying too much on book-learning, being sceptical about the Marauders being animagi when only seven legally registered animagus existed in the last century (Remus has to correct her that it was possible for people to become illegally unregistered animagi), writing off the Deathly Hallows as just a myth despite the evidence of the Cloak of Invisibility, which Ron is the first to point out (namely that the Potters' cloak had lasted as a heirloom generations when Invisibility Cloaks usually fade as time goes by). Harry privately agrees with Xeno Lovegood that she can be narrow-minded.
    • Hermione in the original books was also plain looking, having large teeth, and her appearance at the Yule Ball was surprising to everyone (albeit not Ron, who had a crush on her from before) for that drastic contrast (Harry himself noting in Book 4 that she was unrecognizable at first). In the film, this distinction is lost on account of Emma Watson's casting and the overall Adaptational Attractiveness of the cast. Likewise, Hermione's generally abrasive nature, even passive-aggressive bullying to Luna (who she calls "Loony"), and her well-intentioned but initially clumsy approach to House Elf activism, and also her ruthless edge (such as blackmailing Rita Skeeter and putting the Sneak Jinx) and other flaws gets glossed over, with the likeable, shrewd and vulnerable Rounded Character of the original books being Lost in Imitation in the rather more idealized adaptation.
    • Many fans have cited Hermione as a kind of activist on account of her proactive behaviour about SPEW in Book 4, the DA in Book 5, and her decision to jinx Marietta Edgecombe and erase her parents memories. In the books, her Character Development towards the wizarding world's Fantastic Caste System (at least to creatures) becomes more moderate and reformist by the end of the books. For instance, after coming to understand the Blue-and-Orange Morality of House Elves better, she goes from liberty-or-death about House-Elves to convincing Harry to be a kind master to Kreacher in Book 7.
  • Undying Loyalty: To Harry. Above everyone else in the series, it is Hermione and Ron who stand beside Harry at every twist and turn in his path to stop Voldemort.
  • The Unfair Sex: Averted in Book 6. After Ron found out that Hermione might have kissed a guy who asked her out two years prior while she was single AND getting told that his overbearing watchdog tendencies about his sister were due to his own inexperience with girls, he gets into an extremely shallow relationship with basically the first girl to give him the time of day, largely out of spite. He is portrayed as insensitive and, given how publicly he flaunts the relationship, pretty hypocritical, and quickly gets his own comeuppance by means of his “girlfriend” being utterly insufferable. Hermione attempts to retaliate by accepting to go out with the Jerk Jock… only for the plan to implode immediately, since she genuinely can't stand the guy. Harry, and by extension the narrator, are quick to point out that they're both idiots, though he's slightly more overtly critical of Hermione, possibly owing to the fact that Ron was being an impulsive idiot who didn't think things through, whereas Hermione was being consciously and deliberately petty.
    Narrator: "Harry was left to ponder in silence the depths to which girls would sink to get revenge."
  • Unperson: She wipes her parents' memories of her in Deathly Hallows to keep them safe (in the movie, even going so far as wipe herself from any pictures with her on them). Rowling stated that after the Trio's victory over Voldemort, she found her parents and restored their memories.
  • Unresolved Sexual Tension: With Ron.
  • Unusual Pop Culture Name: According to Rowling, Hermione Granger was named for the character from the the Shakespeare play The Winter's Tale in an effort by her parents to seem more sophisticated. At the time the name was fairly obscure.
  • Unwanted Assistance: In-Universe the house-elves think this of Hermione, as they are offended by her failure to understand that they find Happiness in Slavery and aren't unintelligent beings who need her help.
  • Uptight Loves Wild: The rule-abiding, perfectionist Hermione fell for the easy-going, rulebreaking Ron.
  • Uptown Girl: Zig-Zagged. Rowling says she's from a well-to-do Oxford family, and she winds up marrying Ron, whose family is infamous for their financial struggles. To the haughty Purebloods like the Malfoys, Blacks, and Yaxleys it would be the other way around. While Ron might be from a dirt poor and ridiculed family he is still a Pureblood from a very old family and Hermione is a Muggle-born, the lowest of the low to them, except for Muggles.
  • Victoria's Secret Compartment: Done twice. First when hiding her Time-Turner in Prisoner of Azkaban, and again in Deathly Hallows when she wears the locket Horcrux.
  • White Man's Burden: Briefly, during her house-elf liberation subplot in Goblet of Fire. Played with, as everyone at Hogwarts, even the narration, points out that while she does have a few good points about the treatment of house-elves, she's basically staging a one-woman campaign for house-elf freedom without so much as consulting the subjects she's trying to free, and having only met two house-elves in her life: Dobby, who is a total weirdo by House Elf standards, and Winky, who was in considerable stress at the time.
  • Wise Beyond Her Years: Averted. She may speak a lot about people's feelings, but more often than not she is wrong, or whatever advise she may offer comes late. Case in point, she was convinced that Tonks was sad about Sirius death, but Ron pointed out that they barely knew each other. And he was right, she was sad because Remus rejected her. Also she refuses to believe that the Deathly Hallows are real. Despite having participated in the Chamber of Secrets Mystery, been hunting Horcruxes, being friends with the only person that has survived the Killing Curse and other things. She is also terrible at handling her relationship with Ron, specially in Book 6. All in all she may do well in school work, but she is not very wise or emotionally inteligent.
  • Woman Scorned: She weaponized birds after Ron kissed Lavender. She also chose a date specifically on the basis on "who would annoy Ron most," and went out of her way to hint that she had chosen him because McLaggen was superior to Ron as Quidditch player.
  • Women Are Wiser: Hermione, the only female member of the Trio, is the smartest and doubles as The Spock.
  • Zombie Advocate: Hermione becomes a "House-Elf Advocate" during her fourth year and onward. She even forms an organization called, "Society for the Promotion of Elfish Welfare" or S.P.E.W. for short. Apart from her, no one takes it very seriously.

"I'm hoping to do some good in the world!"
