The Trio

McGonagall: Why is it, when something happens, it is always you three?

Harry Potter, Ron Weasley, and Hermione Granger, the three main characters. They became friends in the first book and, over the course of the series, they have endured and suffered in seven years more than most people do in a lifetime, but they have only become closer over the years. They spend more time together than they do with anyone else, and whenever there is a problem, they always try to solve it together.


While Harry is nominally The Leader of the three person team, he, Ron, and Hermione often defer to each other. In the future, they become family in the legal sense, as Ron marries Hermione and Harry becomes Ron's brother-in-law through his marriage to Ginny, so Hermione is Harry's sister-in-law.

  • Author Avatar: Rowling has admitted that each of the three main characters are aspects of herself. Mostly Hermione though, who is, by J. K. Rowling's own admission, an exaggeration of herself when she was younger.
  • Badass Crew: Every book they take on things that would be considered challenging to experienced wizards, and survive all of them, starting with a troll in the first book, and ending with the Final Battle in the seventh. Harry is accomplished at Defence Against the Dark Arts, quick on the draw, and more than capable of holding his own against more experienced wizards, Ron is a Crouching Moron, Hidden Badass, and Hermione is a Badass Bookworm.

  • Beauty, Brains, and Brawn: Chick Magnet Harry, Insufferable Genius Hermione and Hot-Blooded Ron fit this trope.
  • Best Friends-in-Law: In the end, Ron marries Hermione and Harry marries Ginny (Ron's sister), making Ron and Hermione Harry's in-laws.
  • Blonde, Brunette, Redhead: After the fourth movie, where Emma's bushy brown hair got highlighted so much it became blonde (a movie role in a different film outside of the series may have helped). Ron is the redhead and Harry is the brunette.
  • Break the Cutie: Each of them have been through some heartbreaking moments in the series.
  • Character Development: The trio each mature, in their own way, by the end.
    • Harry goes from a naive, inexperienced young boy who had a "Black and White" concept regarding the houses of Hogwarts (e.g., Slytherin = bad, Gryffindor = good) to a hardened, battle-ready, powerful adult wizard who now sees the "Grays" in all of the Houses. In fact, he told his son, Albus, that it didn't matter to him (or Ginny) if he was chosen to be a Slytherin.
    • Ron as of Book 7. Being forced away from his usual comfort zone, facing his greatest fears in the form of one of Voldemort's horcruxes, and the war in general really made Ron a more mature and sensitive individual.
    • Hermione does undergo some subtle development. She starts off as a bossy, insecure, neurotic, rule-abiding little girl, best exemplified by equating being expelled from school with being killed. By the 5th book, she will now do as much rule breaking if it's to help her friends, family, and the wizarding world.
  • Chromatic Arrangement: In the movies the trio each have their own specific colours: Harry is blue, Ron is red, and Hermione is pink.
  • Colour-Coded Characters: Specifically in the films, each of them had their own scheme colour when not in their Hogwarts uniform: Harry (blue), Ron (orange), and Hermione (pink).
  • Cool Kid-and-Loser Friendship: Harry is famous at Hogwarts and qualifies as the Cool friend to Ron and Hermione who are not particularly popular on their own.
  • Despite the Plan: The usual sequence goes along the lines of "Hermione comes up with The Plan, the trio puts it into motion, things go horribly wrong and Harry steers things to at least partially successful completion, either by adapting successfully or just straight up improvising." Lampshaded in the last film: "Hermione, when have any of our plans actually worked? We plan, we get there, all hell breaks loose!"
  • Fire-Forged Friends: The troll incident is what forms their friendship; others solidify it.
  • Freudian Trio:
    • Hermione is firmly the superego. Intelligent, respectful to authority, has proper 'manners'. Her 'know it all' quality can get on the other characters nerves. Likes organization and neatness, the one who most often refuses to eat if something perceived as more important is at play, is almost always the first one to advocate sticking to the rules or the established way of doing things, has academic and theoretical knowledge of the magical world gained by education and research but is ignorant of a lot of magical social conventions (i.e. house-elves, "giants are really all that bad, it's just wizard propaganda", the tales of Beedle the Bard).
    • Harry is the id when the going gets rough. He has "a saving people thing" as Hermione says in Harry Potter and the Order of the Phoenix, and is the most prone to impulsive and irrational behavior when the shit hits the fan. In casual situations, he is the ego; he's not messy, not tidy, eats normally, breaks rules for a good cause but will usually play it safe, has neither intuitive nor academic knowledge and usually relies on the other two to explain things.
    • Ron is the ego when things get hairy. He acts as the 'middle' of the two when Harry wants to rush off to save somebody but Hermione wants them to take their time being as cautious as possible. In more laid-back scenarios, he's the id; he's generally messy, eats at every opportunity to do so, is almost always the first one to advocate breaking a rule, good cause or not, has intuitive and social knowledge of the magical world gained by being a native but isn't up-to-snuff on how magic works on a scientific level.
  • Good Parents: They all become this to their children in the epilogue. Ron and Hermione are doting and loving to their daughter (Rose) and son (Hugo). Harry with Ginny are supportive parents to their three children (James II, Albus, and Lily) and tell their middle child that they won't disown him or be disappointed if he gets sorted into Slytherin.
  • Interclass Friendship: Harry is implied to be somewhere between very and obscenely rich. Ron is a member of the poorest family depicted in the novels. The issues of class are played down in that Harry was raised by muggles and more or less a Spear Counterpart to Cinderella in that he lived as a poor servant to a rich step-family but then gets pushed forth into celebrity-superhero-dom. The class issues don't become part of their dynamic until Book 4, where Harry casually admits that he forgot about missing Leprechaun gold. Ron mutters that if he got a sum of that much gold he would certainly notice it missing.
  • Kid Hero: Until they become full grown adults in the seventh book. Deconstructed since they are forced to deal with things that greatly interfere with their social lives and suffer trauma aplenty, especially Harry.
  • Like Brother and Sister: Rowling confirmed around the time of the fourth book that Harry views Ron and Hermione as his adopted brother and sister, something Harry reiterates occasionally. It causes some tension with Ron due to his own romantic feelings in Hermione in Deathly Hallows until Harry and Ron have a very intense argument about it.
  • Nice Mean And In Between: Downplayed, as all three are kind and heroic individuals, but Harry, being a compassionate, warmhearted All-Loving Hero, is hands-down the nicest one of the group, though he is still able to stand up to meaner characters whenever he doesn't want to put up with their crap. Ron is prone to easily losing his temper and can get jealous, especially if anyone other than him does anything romantic with Hermione, though he does become more and more sensitive as the series goes on. Hermione, while having moments of being bossy and somewhat vain about how smart she is, is still a pretty level-headed and well-meaning person and does know when to be kind and who to be kind to if ever they need it.
  • Red Baron: All of them receive their own title by the end of the series:
    • Harry- "The Boy Who Lived"
    • Ron- "The King"
    • Hermione- "The Brightest Witch Of Her Age"
  • Red Is Heroic: In the films they wear red-and-gold ties as part of their school uniforms, as Gryffindors, and Harry wears a red sweater during the crux of Philosopher's Stone.
  • ¡Three Amigos!: They are a trio of friends and the stars of the franchise, and have been pals since they were 11.
  • Token Trio:
    • Harry is a half-blood, Ron is a pure-blood, and Hermione is a Muggle-born.
    • Also, pre-Deathly Hallows, the three had, according to Rowling, the three different wand cores offered at Ollivanders: Harry has phoenix feather, Ron has a unicorn tail hair, and Hermione has a dragon heartstring.
    • Harry, Hermione, and Ron represent wealth, the middle class, and poverty, respectively.
    • Also with the three others Hogwarts houses except Gryffindor (as lampshaded for Harry and Hermione in the books at least): Harry is cunnning and has similarities with Voldemort and would have fit into Slytherin, Hermione is book-smart and as studious as a Ravenclaw and Ron is as loyal and light-hearted as a Hufflepuff.
    • In the books, when Harry Potter, Hermione Granger, and Ron Weasley discuss the Hallows at Xenophilius Lovegood's house, they each choose a different Hallow that they'd rather have: Harry chooses the Resurrection Stone, Hermione chooses the Cloak of Invisibility, and Ron chooses the Elder Wand. This matches with their respective personality. Hermione is wise and prudent, Harry is regretful and pained by deaths in his past, and Ron is ambitious and power-hungry.
  • Took a Level in Badass: All three of them become stronger in some way by the end.
    • According to JKR, Harry became the best duelist in his circle of friends during his Third Year. Probably graduated to "best student duelist in the school" a year later, as the Triwizard Tournament pushed him into successfully learning several combat spells far beyond his expected level. All in all, Harry goes from bullied and timid kid to a pretty reasonable all-round badass by book 4 at the latest. You could argue he takes a further one of these in the final book, going to his death calmly, then just as calmly offering the man who killed his parents and a lot of his friends a chance at redemption, admittedly almost certain that he wouldn't take it.
    • Ron is a more emotional/mental variety. In the first book, he went from not even calling Voldemort by his full name to insulting the man himself in the finale.
    • Hermione started off as a girl who would never dreamed of breaking the rules. Come Book 7, she will use any illegal skill to insure success for her and her loved ones. A more standard example of the trope in the fact that she becomes a very good fighter only in the later books.
  • Tragic Dropout: All three are forced to leave Hogwarts in what would have been their seventh year in order to hunt down the horcruxes and avoid getting killed by the new Death Eater regime. That said, Harry and Ron downplay this since weren't the best students to begin with and their lives turn out okay in the end (they both become Aurors). Hermione is an outright subversion since she does return to Hogwarts and graduates offscreen after Voldemort's defeat.
  • Tragic Keepsake: Each of them received a memento from Dumbledore in Book 7, which happened recently after his death. See their character sections for specifics.
  • True Companions: They are closer than siblings, and even closer than lovers. Their loyalty to each other is absolute.
  • Two Guys and a Girl: Harry and Ron are both boys while Hermione is a girl.
  • Vitriolic Best Buds: All of them fight, but Ron and Hermione bicker the most.
  • Walking the Earth: To find the horcruxes.
  • Weirdness Magnet: Lampshaded more than once; why does everything interesting or dangerous happen to them?
    • From the Half-Blood Prince film.
      McGonagall: Why is it, when something happens, it is always you three?
      Ron: Believe me, professor, I've been asking myself the same question for six years.
    • Lampshaded by Ron as early as book one, when he sarcastically asks what it would be like to have a peaceful life.
    • Also lampshaded by Harry when Hermione tells him that Malfoy could use his prefect privileges to make Harry's life difficult. Harry sarcastically wonders what it would be like to have a difficult life.
  • With Friends Like These...:
    • Both Harry and Ron row with Hermione, Ron more often than Harry. Harry and Ron row only twice, for a month in book four and when Ron leaves for a month in DH. Which, given that the heroes are between 11 and 18 years old during the course of the series, is not exactly unbelievable.
    • Harry is usually the peacemaker. Hermione plays peacemaker once and can't stand it, and Ron never has to because mostly when Harry fights with Hermione to the point of not speaking with her for longer than a few hours, it's because he sides with Ron. The most memorable exception to this was when Hermione turned in the broom that Sirius sent Harry. That time, Ron sided with Harry.
