One interesting plotline could be the exploration of how different wizarding families deal with the war. For example, some might be forced to choose sides while others try to stay neutral. Another could be the discovery of new spells and magic specifically created for the war effort. And there might be stories about how Hogwarts students form secret resistance groups within the school.
A great plotline could be the idea of a prophecy that was hidden until the war. It could be about a powerful wizard or witch who has the ability to end the war, but no one knows who it is. This would create a race between the two sides to find this person first. Also, some fanfictions might look at how the Muggle world is affected by the wizarding war in ways they don't even realize, and how wizards try to keep it a secret from Muggles while fighting their own battles.
In some fanfictions, there could be a plotline where the Death Eaters have a new and more powerful weapon. This forces the Order of the Phoenix to come up with creative ways to counter it. There may also be a focus on the relationships between characters that are strained during the war, like Harry and Draco, and how they navigate their differences. Additionally, fanfictions might explore how the magical creatures side during the war.
In some 'Spoils of War' fanfictions, the spoils could be knowledge. Maybe a hidden library full of dark or ancient magic spells is found. This knowledge then becomes a source of conflict as different characters vie for control over it. Some might want to use it for good, while others for more sinister purposes.
One interesting plotline could be Harry having to face new and more powerful dark wizards that are emerging in the post - Voldemort era. He might have to use his skills in a different way. Another could be Harry exploring his family's history more deeply and finding secrets that change his perception of himself. Maybe he discovers some long - lost relatives who have their own magical abilities and stories.
In this type of fanfiction, a great plotline could be the exploration of the characters' post - war traumas through their relationships in the harem. Harry, for instance, might have nightmares about the war. His 'harem' of friends and potential love interests could be there to comfort him. Hermione could use her intelligence to help him analyze his feelings, Ginny could be the one to bring out his more carefree side, and other characters could contribute in their own ways. This way, the harem setting becomes a means of healing and growth for all the characters involved.
One interesting plotline could be about the rebuilding of Hogwarts. The war has left it in ruins, and the characters have to come together to restore it to its former glory. They might face challenges like finding the right magical materials and dealing with the memories of the battles that took place there.
One interesting plotline could be a muggle accidentally stumbling into the wizarding world and having to learn the ropes quickly. For example, they might find themselves in Diagon Alley and be completely bewildered by all the magical shops and strange creatures. Another could be a wizard falling in love with a muggle and trying to keep their magical identity a secret while still building a relationship. And a third could be muggles being recruited to help with a wizarding problem that only their unique muggle skills can solve.
One interesting crossover could be a magical school exchange. Wizards from the Harry Potter universe visit Waverly Place's wizard school and vice versa. They could compare and contrast their different magical systems, like how spells are cast or potions are made. It would be really cool to see Harry Potter characters interact with the Russo family and their friends.
In Harry Potter fanfic, many consider characters like a super - powered Harry Potter as one of the strongest. He might have enhanced magical abilities, like being able to perform extremely advanced spells without much effort. Another could be an AU (Alternate Universe) version of Dumbledore who has even deeper knowledge of ancient magics. Also, a fan - created dark wizard who has combined different dark arts to create a new and terrifying form of magic could be considered strong.
Well, some might involve magical creatures with furry characteristics in new adventures at Hogwarts. For example, a werewolf character could have a unique story arc that intersects with the main Harry Potter plot. Maybe they are trying to find a cure or dealing with the prejudice within the wizarding world in a different way than what's in the original books.
One possible plotline could be a comical take on baby Harry's magical mishaps. Maybe he accidentally makes his diapers levitate or turns his crib into a mini Hogwarts. Another could be about how the other characters like Hagrid or Dumbledore interact with baby Harry in this unique situation, perhaps trying to figure out how to handle his early magical outbursts while he's still in diapers.
Perhaps a plotline where the ogre has some sort of special power that the wizards in Harry Potter are interested in. This could lead to a whole series of events where they try to either control or cooperate with the ogre.
