What are some interesting plotlines in 'Harry Potter travels to alternate universe fanfic'?

One interesting plotline could be Naruto arriving in an alternate universe where the Akatsuki are the heroes. He has to figure out how to navigate this new world where his former enemies are now revered.

One interesting concept could be a world where Voldemort won the war. In this alternate universe, Hogwarts might be a very different place, with dark magic being taught openly. Another concept could be a universe where the houses are not divided as they are in the original. Maybe students are grouped based on different criteria like magical talents other than just bravery, intelligence, etc. For example, there could be a group for those who are good at magical creatures handling.

Well, Hermione is often depicted in different ways in these fanfics. In some alternate universes, she could be a powerful dark witch instead of the studious and good - hearted character we know. Ron might be a super - confident and arrogant character rather than the sometimes insecure boy in the original story. Also, Snape could be a completely different person. He could be a jolly and friendly teacher rather than the brooding and complex one we are used to.

One interesting plotline could be Naruko having unique ninja abilities that are different from Naruto in the original series. For example, she might have a special water - based jutsu that no one else has. Another could be her relationship with different characters. Maybe she has a closer bond with Sakura and they form a powerful all - female ninja team.

One idea could be that in this alternate universe, Hufflepuff is the dominant house in Hogwarts. They have a secret society within the house that holds the key to an ancient magic that can save the wizarding world from a new, unknown threat. And the main character, a Hufflepuff student, discovers this by accident and has to take on the responsibility to gather the members of the society.

Perhaps he meets a version of his parents who are still alive. This would be an incredibly emotional encounter for Harry. He would get to know them, and they could teach him things about magic and life that he never had the chance to learn before.

He might meet different versions of his friends. For example, a Hermione who is a powerful sorceress ruling a magical kingdom. It would be exciting as he could learn new magic from her and be part of her adventures in this alternate reality.

One interesting AU could be a world where the Triwizard Tournament is open to all years. This would change the dynamic completely as younger students might participate, bringing in different skills and strategies. Another could be an AU where Voldemort never came back in the fourth year, and instead, a new dark wizard rises to power in Hogwarts, creating a different kind of threat for Harry and his friends. A third concept could be an AU where the Hogwarts houses are mixed up for the fourth - year students, forcing them to work with those they usually wouldn't and leading to unexpected friendships and rivalries.

In this type of fanfiction, the concept of character evolution is fascinating. In an alternate universe, the characters may face different challenges that accelerate or change their growth. For instance, Yang might have to overcome a different kind of personal trauma. Also, the concept of the alternate universe's history and how it affects the RWBY characters is interesting. Maybe there was a different Great War in one universe, and that has shaped the current state of the world and the characters' place in it.

One interesting plotline could be that in the alternate universe (au), Harry Potter discovers a world where magic is used in completely different ways. For example, instead of using wands, they use amulets. Another could be that he finds himself in a world where Voldemort won the war in his own universe, and he has to figure out how to change things in this au. Or perhaps he travels to an au where Hogwarts is a school for all magical creatures, not just witches and wizards.
