Harry Potter and the Ice Princess by gadman85
is a crossover series between Harry Potter and Frozen, relocating the events of Frozen to a time period where Elsa is basically Harry’s contemporary and her abilities are an extension of a more conventional magical ability. After the accident where she wounds Anna, Elsa learns more about her family’s true history of magic and begins to receive instruction from a tutor before she takes up her family’s traditional role of attending school at Hogwarts… at the same time as the Boy-Who-Lived starts at the school.
As of October 2020, this series consists of three stories; “Book 1” (an alternate take on Harry Potter and the Philosopher's Stone), “Book 2” (an alternate take on Harry Potter and the Chamber of Secrets) and “Book 3” (an alternate take on Harry Potter and the Prisoner of Azkaban, currently still in progress)
Harry Potter and the Ice Princess contains examples of:
- Adaptational Villainy: Aragog, bizarrely enough. In canon, no matter how callously he treated Harry and Ron, his affection and loyalty to Hagrid himself were genuine and after his death it became apparent just how much he was doing to keep his less reasonable children from running berserk in the Forest. Here, he's revealed to have been using Hagrid all along because the Forest was such an easy life for him and his family with no real predators and lots of readily available food. Moreover, he was planning on invading the castle with his children and eat everyone.
- Ascended Extra:
Word of God confirms that all of Elsa's year-mates are canon characters from the series, who just never got much in the way of character development in the original novels (By contrast, Anna's roommates are all original characters, such as Hannah Abbott's little sister).
- Bait-and-Switch: The goblins do this for the accounts test; a negative result produces smoke while a positive result doesn’t give any signs, allowing the goblins a chance to taunt customers who failed the test and were rude, while breaking the news gently to nicer customers.
- Beware the Nice Ones: Elsa is kind to everyone from house-elves to the eccentric Luna, but single-handedly destroys Aragog and his family to stop them being a threat in future, and the only reason she didn't kill Tom Riddle in the Chamber of Secrets was because he didn't have a body.
- Birds of a Feather: A more literal example than most; when Elsa meets Harry, she notes that Hedwig is particularly intelligent by owl standards, comparing Hedwig to her and Anna's owls.
- Broken Bird: Downplayed for Elsa, as she has better training of her magic rather than just trying to repress everything, even if she still had some trouble accepting the scale of her ice abilities at first.
- Canon Welding: Elsa’s magic is a trait that occasionally shows up in the royal family, with her control of ice an extension of her more conventional magical potential.
- Continuity Cameo: Olaf appears very briefly in Book 2, when Elsa demonstrates her ice powers for Nicolas and Penerelle Flamel. She makes him appear to say his trademark catchphrase, "I'm Olaf and I like warm hugs," but when she makes him disappear again he looks disappointed and says "Awww… Looks like I have to get going for now. I hope to see you again!", which surprises her because she hadn't intended to make him say that.
- Distracted by the Sexy: In as much as one thirteen-year-old can think of another as 'sexy', Harry tries to avoid this happening to him by trying not to pay too much attention to the sight of Elsa in a two-piece swimsuit, and is later briefly distracted at the image of Elsa dancing naked in a blizzard.
- Everyone Has Standards: When Peeves witnesses a possessed Ginny attempting to open the Chamber, "Riddle" has to wipe Peeves' memory of the encounter before he reports it, as Peeves is only interested in mischief but would never do anything that would outright endanger any of the students or staff.
- Exact Words: Elsa often chooses to talk about her family history with her friends while just avoiding anything that identifies her as royalty.
- Good Is Not Nice: In Book 2, Elsa kills Aragog's entire Acromantula colony to stop them being a future threat.
- Good Parents: The king and queen show better understanding of Elsa’s powers, albeit aided by the tradition of magic in the royal family giving them a superior precedent to follow.
- Green-Eyed Monster: As third year begins in particular, Harry struggles with his own jealousy about Elsa spending time with Malfoy despite the fact that he knows Elsa is aware of Malfoy's ulterior motives for spending time with her and is just doing it to make sure he doesn't do anything stupid.
- Happily Adopted: Not in the sense of becoming their actual child, but Elsa's parents propose an option where Harry becomes a ward of Arendelle rather than having to return to the Dursleys, granting him similar protection so long as the trolls perform appropriate rituals.
- Handicapped Badass: Talking with Ron and her dorm-mates about how he uses an old wand, Elsa observes that Ron must be more powerful than he knows if he’s able to get the results he gets in class while using a wand that didn’t choose him.
- I Just Want to Be Normal: May be the best description of why Harry and Elsa get along from their first meeting on the train, as Elsa’s the first person Harry’s met in the wizarding world who doesn’t know about his ‘celebrity status’ and still chooses to spend time with him.
- An Ice Person: Downplayed; Elsa still has her ice powers, but she’s focusing on training herself in her other magical abilities at Hogwarts while keeping her powers discreet.
- In Spite of a Nail:
- Despite Harry, Ron and Hermione having a closer friendship with Neville and Elsa’s presence in Hogwarts, their first couple of years at Hogwarts unfold basically the same as they did in canon.
- Although Elsa is able to prevent Malfoy being attacked by Buckbeak by keeping an eye on him during the lesson, another Slytherin still provokes the Hippogriff.
- Internal Reveal: Elsa only reveals her royal lineage to any of her friends when fighting Riddle alongside Harry in the Chamber of Secrets, and even then she only tells Harry.
- King Incognito: Elsa’s status as a princess is not known to the general population of Hogwarts; only Dumbledore, McGonagall and Flitwick are shown to be aware of it (and Flitwick is only told because he’s Elsa’s Head of House), while Harry learns the truth after the confrontation with Riddle in the Chamber of Secrets.
- Living Emotional Crutch: Elsa greatly depends on the support of those who know about her powers, such as Harry and Anna as of Book 3, to be assured that she won't let them make her a bad person.
- Mythology Gag: While playing together as children before Elsa starts at Hogwarts, Elsa and Anna dress up as the ‘Duke of Weselton’ and ‘Princess Hansetta’, based on historical figures rather than living people. Later Elsa’s parents reflect that it’s too bad there’s a ski resort on a nearby mountain, as a couple of centuries ago Elsa could have built an ice palace there without fear of being discovered.
- Nice to the Waiter: It is frequently noted that Elsa has been taught that being a kind ruler is better than ruling through fear, as fear only lasts until someone stronger comes along where kindness can inspire greater loyalty.
- Nothing Is Scarier: When discussing Harry's fears of the Dementors, Elsa observes that the relative vagueness of the memory they inspire makes the experience worse for him.
- Paper-Thin Disguise: Discussed when Harry asks Elsa how she can get away with travelling under her real name, as Elsa observes that few people actually know the names of the royal families of even their own countries and so most of the time she can pass her sharing the name of the royal family off as just a coincidence, particularly since she hasn’t been ‘officially’ introduced to her kingdom yet.
- Place of Power: Played with regarding Arendelle; there is so much natural magic there that relatively few witches and wizards manifest as their natural powers are ‘lost’ in the general background magic of the country, although Lucius Malfoy notes that those witches and wizards who manifest in Arendelle are shown to be exceptionally powerful elsewhere.
- Pragmatic Villainy: It is observed that the Malfoys have a relatively good working relationship with the royal family of Arendelle even though the family are ‘officially’ muggles, as Lucius Malfoy recognises that he benefits from the current arrangement and the royal family could easily find someone else if he ever disagreed with their terms.
- Rags to Riches: Harry is known to be rich in canon even if he doesn't exploit his status, but he has more opportunities to use his wealth after he becomes a ward of the King and Queen of Arendelle.
- Really Royalty Reveal: Elsa tells Harry that she’s the Crown Princess of Arendelle after the battle in the Chamber of Secrets.
- Reasonable Authority Figure: Despite his own plans for Harry, once Dumbledore is informed that Harry has become a ward of Arendelle, he accepts this decision and even accepts the Hogsmeade form signed by the King and Queen for Harry (after confirming it was only signed after they became his guardians).
- Right for the Wrong Reasons: Various students refer to Elsa as the 'Ravenclaw Princess' just because of her manner, with very few aware that she actually is a princess by birth.
- Royals Who Actually Do Something: Elsa may be a princess, but she’s willing to help out Harry and the others.
- Running Gag: Students all avoid telling new students what is actually involved in the Sorting ceremony, with fake claims including that they have to wrestle a troll in their underwear.
- Selective Obliviousness: Albeit induced by the Diary, but Ginny is so focused on talking with Tom about her time at school that she doesn't realise her dorm-mates are having the same kind of conversation as she is.
- Serious Business: Subverted in terms of the characters’ opinions on Quidditch, as Ron is the only true ‘fanatic’ for the sport, with Harry enjoying the game without being obsessive and Hermione, Neville and Elsa just going along to show support for their friend, Elsa abstaining from showing support to either side in the Gryffindor/Ravenclaw matches. While Oliver Wood is still keen on the game, he is ‘rational’ enough to accept Harry’s assurances that letting Elsa watch them practice isn’t a risk as she doesn’t play the game herself and Harry trusts her not to give the Ravenclaw team any ‘tips’.
- Setting Update: Frozen and relevant events are relocated to approximately the present day so that eleven-year-old Elsa is attending Hogwarts at the same time as Harry Potter and his friends start their first year.
- Ship Tease: Although they are barely teenagers yet, Harry and Elsa have been very strongly hinted to have more-than-friendly feelings for each other.
- Shipping Torpedo: Elsa only ever saw Malfoy as a friend at best, but when Harry and Ron infiltrate Slytherin under polyjuice, they confirm that Draco is judging his potential relationship with Elsa based on how it would benefit him socially rather than showing any appreciation for her as a person, affirming to Elsa that she will never date Malfoy.
- Shut Up, Hannibal!: A relatively minor example, but when a prospective Slytherin first-year starts trying to taunt Anna and her new friends during the boat-ride to Hogwarts, Anna shuts the girl up by observing that Slytherins are just as predictable as they claim Gryffindors are.
- Social Climber: Lucius Malfoy is shown contemplating making arrangements for Draco to become involved with one of Arendelle’s princesses to boost his own family’s social status.
- Took a Level in Badass:
- Elsa develops her skills as a witch throughout the story.
- In a subtle manner, Neville gains greater self-confidence with Elsa giving him some tutoring in potions; by the time he confronts a boggart in the third-year Defence class, he no longer fears Snape specifically, but has a more 'generic' fear of escaped Death Eaters.
- Wham Episode: Chapter 29 of Book Two reveals that Anna has regained her memories of Elsa’s magic and also has magic herself, with the result that she will attend Hogwarts next year.
- What Measure Is a Non-Human?: It is revealed that (as confirmed by Word of God) Elsa can see Thestrals after killing the Acromantulas, as the Acromantulas are close enough to humans in terms of their ability to speak that it counts as Elsa seeing someone die.
