In harry potter multiversal fanfiction, a great concept is the existence of magical creatures that are different from the ones in the original series. Maybe in one universe, there are giant flying serpents that are used for transportation instead of broomsticks. Another interesting aspect is the different political systems in the wizarding world across universes. Some universes could have a more democratic system where all wizards have a say in the running of the magical government, while in others it could be a more autocratic rule. And then there's the idea of different prophecies in each universe, which would greatly affect the actions and destinies of the characters.
Well, in harry potter multiversal fanfiction, the idea of time - traveling in different universes is really cool. Imagine Harry going back in time in a parallel universe to change the outcome of the Battle of Hogwarts. Also, the concept of different forms of magic is fascinating. There could be a universe where magic is more elemental - based, with wizards being able to control fire, water, earth, and air more directly. And of course, the relationships between characters can be re - imagined. Hermione might end up with Draco in one universe, which would be a huge departure from the original story and would create a whole new set of storylines and character developments.
One interesting concept could be alternate versions of Hogwarts. For example, a Hogwarts where the houses have different characteristics or where the magic taught is more focused on a particular type of magic like dark magic being taught openly (in a more morally grey fanfic). Another concept might be different fates for the main characters. Harry could be a Slytherin instead of a Gryffindor, which would lead to a completely different story arc. There could also be crossovers with other fictional universes in the multiversal fanfiction, like Harry Potter characters interacting with characters from Lord of the Rings or Star Wars.
One interesting concept could be exploring more about the Marauders' time at Hogwarts. Fanfiction might expand on their adventures, like pranks they played that were never mentioned in the original book. Another could be different interpretations of Sirius Black's escape and his relationship with Harry during that time.
Some fanfictions in Harry Potter 2 might play with the idea of the basilisk having different powers or weaknesses. It could also explore the idea of a hidden connection between Ginny and the Chamber of Secrets that goes beyond what was in the original story. There might be fanfictions that change the role of certain characters, like making Neville a more central figure in solving the mystery of the Chamber.
It expands the story by introducing countless alternate realities. For instance, we might see a world where Voldemort won and how the remaining characters survive and resist under his rule. This creates a whole new set of storylines and character arcs. It also allows for the exploration of different character relationships. Characters who were enemies in the original might be friends in a multiversal fanfic, like Harry and Draco.
One interesting concept could be exploring new magical creatures in the Harry Potter kingdom. Maybe there are some hidden species that haven't been discovered in the original series. Another could be alternative forms of magic that are unique to the fanfiction's version of the kingdom. And also, new relationships between different houses or characters can be quite fascinating.
One interesting concept could be the use of magic in relation to physical laws. For example, how spells might interact with gravity. Maybe a levitation spell actually counteracts the force of gravity in a way that can be explained through some made - up 'physics' in the fanfiction.
Well, some fanfictions play with the idea of blood magic in relation to family bonds. They might show how the blood of one's ancestors can be a source of hidden power or knowledge. For instance, a character discovers that their long - lost relative had a special blood - related spell that can only be activated by someone with their exact bloodline. It adds an element of mystery and heritage to the story.
One interesting concept could be the merging of the magical world of Harry Potter with the demon - slaying elements of Sparda. For example, a character from the Harry Potter universe might gain the power of Sparda and use it to fight dark wizards in a new and unique way. It could also involve crossovers where characters from both worlds interact, leading to unexpected alliances and conflicts.
One interesting concept could be the way animism is incorporated into the magical creatures. For example, how they might have their own spirits or consciousness that is more in - depth than what's shown in the original series. Maybe the hippogriffs have a collective spirit that influences their behavior towards wizards.
Another concept could be the inflation of Hogwarts itself. The castle growing larger and larger, with new and strange rooms and corridors appearing. This could lead to new mysteries for the students to solve, like finding a hidden chamber in the newly - inflated part of the castle that holds a powerful magical artifact.
Another concept is the idea of prophecies being manipulated. In some fanfictions, dark wizards or witches try to change the outcome of the prophecy by interfering with the events or people involved. This can create a lot of tension and drama as the characters fight against this manipulation.
