Hogwarts AU

Hogwarts AU is a popular AU (Alternate Universe) within the Rise of the Brave Tangled Dragons fandom. In the AU, Rapunzel, Merida, Hiccup and Jack Frost are all students at Hogwarts School of Witchcraft and Wizardry. Because it is not canon, ideas for this AU are shown through fanfiction, fanart, and other fan-made works. Hogwarts AU is considered to be the most popular scenario in the RotBTD fandom today.

About the AU
The world of Harry Potter has been a popular universe for all fans to use for crossovers, and this is especially the case in the RotBTD fandom. Hogwarts School of Witchcraft and Wizardry is the perfect location for the Big Four to interact because of a number of reasons; it is an educational institute that gives an excuse for the four to be in the same area, it allows for the use of magic and the idea of dragons, and it adds elements of competition and rivalry between the Big Four and their friendship.

In most cases, being being sorted into separate Houses along with other characters from their respective movies allows for relationship development in unique and creative ways. However, there are few authors that do sort them all into one House to set the rationality of their closeness as friends. Because of how Hogwarts separates their Houses, there is a sense of rivalry between them, and its students rarely get to meet up at the same time outside of double classes.

The Big Four
While most often sorted into Gryffindor for their heroics, the Big Four are often seen sorted in separate Houses as a means to create a sense of camaraderie, "Breakfast Club" style. Some House choices are universally accepted, whereas others are more debatable.

Hiccup Horrendous Haddock III
Hiccup is a hard character to sort from the group and often debated among authors for where he truly belongs. He possesses the hardworking and loyal nature of a Hufflepuff, but also contains the thirst for knowledge and quick wit that is admired and portrayed by many Ravenclaw students. In his feature film, How to Train Your Dragon, he is shown to be intelligent, observant, and clever, as well as being able to use his friends and their dragons' weaknesses and strengths to defeat the Red Death. In rare cases Hiccup may be placed into Slytherin should his fellow vikings also be involved, due to their relationship with dragons (commonly seen as reptilian) and Hiccup's obvious awkwardness from his fellow viking classmates. This puts good perspective on the different sides of the often stereotyped Slytherin student.

Often in this universe, he is known to still have Toothless as a pet dragon, going through the same befriending and training as his film, but within the Forbidden Forest.

Jack Frost
Jack is commonly sorted into Slytherin for his mischievous and sometimes destructive nature which is seen more towards the start of his feature film, Rise of the Guardians. As a result, many stories feature him as a darker, more angst-ridden character compared to the other members of the Big Four, using his Sorting as a point of tension and plot drive. He is usually given a spot on the Slytherin Quidditch team as a Chaser or Seeker, creating a competitive spirit between him and Merida.

Other stories and artists have portrayed him as a Gryffindor, showing him more as a fun-loving trickster to replace the Weasley Twins or the Mauraders. This takes into account his traits of being brave and daring, his more heroic traits he developed near the end of his film.

Rarely Jack has been placed into Ravenclaw, due to the color scheme match and his tendency for witty banter. He is quick on the uptake and years of vagabond lifestyle permits him street-smarts, leading to assume creativity and originality, traits of the house. As the only one amongst the four to maintain a variety of magical powers he can be seen as naturally talented, suggesting an affinity for magic, a common trait of Ravenclaw. Jack is very competitive, a strong tie to the house, and also embodies other ideals of the house such as individuality and acceptance of others.

Depending on the fanfiction, Jack is sometimes returned to his regular mortal state as Jackson Overland in order for people to see him and for him to attend school. On the other hand, regular magic-users might not have a problem believing in and seeing a spirit like Jack, and therefore some writers leave him as the white-haired Jack Frost, even having him fall into the lake beside Hogwarts to receive immortality. His staff is also sometimes converted into a wand to fit within Harry Potter canon, although this is not always the case.

Merida DunBroch
Merida is almost always sorted into Gryffindor, due to her bravery and sometimes foolhardy courage. Gryffindors are seen as strong-willed and sometimes do not think all of their choices through. This often is justified by the character traits she takes on near the end of her feature film, Brave. Alternatively, some people have sorted her into Slytherin because of her ambition, resourcefulness, and self-centered desires, though it is not the primary choice.

Quite often in the fandom, Merida is shown to be on the Gryffindor Quidditch team, usually against Jack as a Beater or Chaser. She also is shown as not being the most astute student, often forgoing homework and studying for more exciting activities. Occasionally, she even takes up archery outside of the classroom.

Rapunzel Corona
It is widely disputed on whether Rapunzel should be in Ravenclaw or Hufflepuff, as she possesses qualities indicative of both. As shown in her film Tangled, her creativity, thirst for knowledge, and her drive to know more about the world outside her tower could sort her to Ravenclaw. However, she also has the traits that could place her in Hufflepuff, such as loyalty, honesty, and patience. Additionally, she is often portrayed with her long blonde hair, however there are some artists that include her with her pixie cut. It is up to fanfiction writers whether her hair is as long or as magical as it is in the movie. Fans have even used her tiara as Ravenclaw's Diadem.

Astrid Hofferson
Astrid is typically placed in either Slytherin or Gryffindor. The fandom seems to be divded in the aspect that she shows many trait for each house. She would be placed in Syltherin for her cunning aspects and he sly nature, but Gryffindor for her brave and run-head-on-into-situations personality. Alternatively, she, along with all of the other children from the village (par Hiccup) attend Durmstrang Institute of Magic.

Flynn Rider
Flynn is also usually placed in Slytherin or Gryffindor. More often than not, he is placed into Gryffindor for his reckless behavior and daring attitude. However, he is sometimes placed in Slytherin for his cunning personality and sly nature, especially at the beginning of Tangled.

The Guardians
Occasionally, the Guardians attend school, but are more commonly seen as teachers rather than students. They are typically portrayed as human. The houses they are placed in are very mixed across the fandom community.

Queen Elsa of Arendelle
While some fans have debated on what houses Elsa is in, the most common house she is in is Slytherin for her introverted personality and her many resemblances to Jack. In other cases, Elsa is portrayed as Rowena Ravenclaw, founder of the House of Ravenclaw. Because she was raised at birth in a refined and wealthy household (the royal family in the original film) Elsa and her sister would also be students of Beauxbatons Academy of Magic, unlike Merida (who's kingdom is young and not as well-refined in comparison) and Rapunzel (who was born to a prosperous kingdom but was not raised in it).

Princess Anna of Arendelle
Due to her courage and initiative (not to mention her borderline recklessness), Anna is often seen as a Gryffindor. This usually puts her a little at odds with her sister, who is commonly made a member of her House's rival Slytherin. In other cases, Anna is portrayed as Helga Hufflepuff, founder of the House of Hufflepuff. Because she was raised at birth in a refined and wealthy household (the royal family in the original film) Anna and her sister would also be students of Beauxbatons Academy of Magic.

Kristoff Bjorgman
For his more passive and neutral personality, Kristoff is placed in the House of Hufflepuff. In other cases, Kristoff is portrayed as Godric Gryffindor, founder of the House of Gryffindor.

Toothless

Toothless is usually shown as being a dragon rather than a human in this AU, since it's a fantasy universe, and therefore, dragons exist. Hiccup will often get him in his time at Hogwarts, but the way he gets him is different from fanfiction to fanfiction. In most cases, it's the same way as shown in How To Train Your Dragon, where the forest in Berk is replaced with the Forbidden Forest. In rare cases, he'll get him from an egg, replacing Hagrid.

It's up to the fanfiction author if the other members of the Big Four would support Hiccup in his beliefs about dragons or react like the rest of Berk - not believe him.

Prince Hans of the Southern Isles
Because of his ambitious initiative and underhanded means to accomplish it, Hans is always placed in Slytherin House. In other cases, Hans is portrayed as Salazar Slytherin, founder of the House of Slytherin. In rarer cases, Hans would also be a member of Beauxbatons Academy of Magic for his refined background, and while the films portray Beauxbatons as an all-girl school, the books claim that the Academy also possess male students.

Mother Gothel
Usually protrayed as Rapunzel's "Mother" like in Tangled she is both devious and cunning as in the movie. Sometimes she is hidden as a staff member in Hogwarts (usually in the contact of Pitch Black) and sometimes she stays in the Tower. However she is always reluctant to let Rapunzel go to school as she fears somebody will discover the power of the flower. Gothel uses her powers of deceit and malnepulation to make the four either start to distrust in themselves and Rapunzel's power. She also hoards the power of the flower to herself.

Pitch Black

Pitch is often a part of this AU, but the way he's portrayed is different.

Sometimes he's a teacher at Hogwarts. He'll be a rather cruel teacher, like Snape, Umbridge or the Carrows. However, many authors find him too evil to be a teacher and instead make him a famous, dark wizard, replacing Voldemort.

In the fanfictions where he's a dark wizard, there will often be duels between him and some of the "good" wizards. In most cases Jack, but sometimes the other guardians or the whole Big Four will fight him.
