->'''[=McGonagall=]''': "Why is it that whenever there's trouble, it's always you three?!?"

[[TheHero Harry Potter]], [[TheLancer Ron Weasley]], and [[TheSmartGuy Hermione Granger]], the three main characters. They became [[FireForgedFriends friends]] in the first book and, over the course of the series, they have endured and suffered more than most people do, 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 TheLeader of [[TheTeam 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 [[ActionGirl Ginny]], so Hermione is Harry's sister-in-law.
* {{Adorkable}}:
** Harry at eleven years old in the first film, with his small stature, glasses, baggy clothes and requisite British accent.
** Ron has red hair, is awkwardly tall and oblivious to love. He is Harry's loyal companion and sidekick.
** Hermione, a bushy-haired, [[{{Bookworm}} bookworm]], who in the first book stutters approximately a third of everything she says.
* AuthorAvatar: Rowling has admitted that each of the three main characters are aspects of herself. Mostly Hermione though, who is, by Creator/JKRowling's own admission, an exaggeration of herself when she was younger.
* BadassCrew: 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 FinalBattle in the seventh. Harry is accomplished at Defense Against the Dark Arts, quick on the draw, and more than capable of holding his own against more experienced wizards, Ron is a CrouchingMoronHiddenBadass, and Hermione is a BadassBookworm.
* BestFriendsInLaw: In the end, Ron marries Hermione and Harry marries Ginny (Ron's sister), making Ron and Hermione Harry's in-laws.
* BlondeBrunetteRedhead: After the fourth movie, where Emma's bushy brown hair got highlighted so much it became blonde. Ron is the redhead and Harry is the brunette.
* BreakTheCutie: Each of them have been through some heartbreaking moments in the series.
* CharacterDevelopment: 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, even with being a StaticCharacter, 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.
* ChromaticArrangement: In the movies the trio each have their own specific colors: Harry is blue, Ron is red, and Hermione is pink.
* ColorCodedCharacters: Specifically in the films, each of them had their own scheme color when not in their Hogwarts uniform: Harry (blue), Ron (orange), and Hermione (pink).
* CoolKidAndLoserFriendship: Harry is famous at Hogwarts and qualifies as the Cool friend to [[UnluckyEverydude Ron]] and [[InsufferableGenius Hermione]] who are not particularly popular on their own.
* DespiteThePlan: The usual sequence goes along the lines of "Hermione comes up with ThePlan, the trio puts it into motion, [[FinaglesLaw things go horribly wrong]] and Harry steers things to at least partially successful completion, either by [[XanatosSpeedChess adapting successfully]] or [[IndyPloy just straight up improvising.]]" {{Lampshade|Hanging}}d in the last film: "''Hermione, when have any of our plans actually worked? We plan, we get there, all hell breaks loose!''"
%%* EarnYourHappyEnding
* FireForgedFriends: The troll incident is what forms their friendship; others solidify it.
%%* FreudianTrio
* GoodParents: 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 Slyhterin.
* {{Kid Hero}}es: Until they become full grown adults in the seventh book. {{Deconstructed}} since they were forced to deal with things that greatly interfered with their social life and has been very traumatic events for them, especially Harry.
* ThePowerOfFriendship: A constant theme in the series.
* PowerTrio: Ron is the Id, Harry the Ego and Hermione the Superego.
* RedBaron: 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"
* RedIsHeroic: 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.''
* ThreeAmigos: They've been friends since they were 11.
* TokenTrio:
** Harry is a half-blood, Ron is a pure-blood, and Hermione is a Muggle-born.
** Also, pre-''[[Literature/HarryPotterAndTheDeathlyHallows Deathly Hallows]]'', the three had, according to WordOfGod, the three different wand cores offered at Ollivanders: Harry has phoenix feather, Ron has a unicorn tail hair, and Hermione has a dragon heartstring.
* TookALevelInBadass: All three of them become stronger in some way by the end.
** [[WordOfGod 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 [[DeadlyGame 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 [[LastSecondChance 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 [[spoiler: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.
* TragicKeepsake: Each of them received a memento from Dumbledore in Book 7, which happened recently after his death. See their character sections for specifics.
* TrueCompanions: They are closer than siblings, and even closer than lovers. Their loyalty to each other is absolute.
* TwoGuysAndAGirl: Harry and Ron are both boys while Hermione is a girl.
* VagabondBuddies: Become this in Book 7 when they search for the horcruxes.
* VitriolicBestBuds: All of them fight, but Ron and Hermione bicker the most.
* WalkingTheEarth: To find the horcruxes.
* WeirdnessMagnet: Lampshaded more than once; why ''does'' everything interesting or dangerous happen to them?
** From the ''Half-Blood Prince'' film.
-->'''[=McGonagall=]:''' "Why is it, whenever something happens, it's always you three?"
-->'''Ron Weasley:''' "Believe me, professor, I've been asking myself that 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.
* WithFriendsLikeThese:
** 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 [[TruthInTelevision 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.
