What are some interesting concepts in 'everything changes' Harry Potter fanfiction?

One interesting concept could be the butterfly effect. When a character travels through time, even a small change can lead to huge differences in the future. For example, a simple decision like stopping someone from getting on a bus can change the course of many lives. Another concept is the alteration of relationships. Time travel might make characters meet in different circumstances, changing their entire dynamic. Maybe a friendship that was strong in the original timeline becomes a rivalry due to time - travel - induced changes.

In this fanfic, there could be a plot twist where the Hogwarts houses' traditional rivalries are turned on their heads. Instead of Gryffindor vs Slytherin, etc., a new threat makes them all have to work together in ways they never expected. The characters might have to overcome their long - held prejudices and form new relationships to face this common danger, which is a big change from the norm in the Harry Potter universe.

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 could introduce new original characters that are central to the story. Maybe a young witch or wizard from a foreign wizarding school who comes to Hogwarts and has a major impact on the events in the fanfic. This new character could bring different magical abilities and cultural elements from their own school into the Hogwarts environment, causing all kinds of changes.

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.
