Maybe in the fanfic, the Deathly Hallows have a different origin or power than in the original books. Instead of just being powerful magical objects, they could be linked to an ancient curse that affects the wizarding world in unexpected ways, like causing random spells to backfire when in the presence of one of the Hallows.
One interesting plot twist could be that a minor character from the original series turns out to be a key player in the fanfic. For example, a Hogwarts student who was barely noticed before might be revealed as a Death Eater spy all along, adding a whole new layer of mystery and danger to the story.
A great plot twist could be that Voldemort has a secret heir in the fanfic. This heir could be hidden among the students at Hogwarts, pretending to be a normal wizard but secretly plotting to continue Voldemort's work. It would create a whole new conflict for Harry and his friends to deal with, as they thought they had defeated Voldemort once and for all.
A really cool plot twist in some fanfictions is that Harry actually has a long - lost sister. This sister could be hidden away by some powerful magic for her protection. Her appearance in the Deathly Hallows time frame would throw everything into chaos as she might have her own ideas about how to deal with Voldemort and the Deathly Hallows.
A really out - there plot twist in fanfiction could be that the Deathly Hallows themselves have a different origin or purpose than what was originally thought. For example, the Elder Wand might be a key to a whole new realm of magic that Voldemort was unaware of, and Harry uses this knowledge to his advantage in the battle against the Dark Lord.
Some fanfictions have a plot twist where the Deathly Hallows are actually a test set by the original founders of Hogwarts. Harry finds out that the real purpose of the Hallows was not just to defeat Voldemort but to bring about a new era of magic in the wizarding world. Another plot twist could be that Snape was not actually killed by Nagini but was in a magically induced coma and wakes up at a crucial moment to help Harry. Additionally, a fanfiction might have a twist where the Horcruxes have a connection to the Deathly Hallows, and by destroying the Horcruxes in a certain order, Harry gains new powers related to the Hallows.
One idea could be exploring what would happen if Neville found the Deathly Hallows instead of Harry. He has shown great courage throughout the series and it would be fascinating to see how he would handle that power.
One interesting plot twist could be Hermione discovering a hidden power within herself related to the Deathly Hallows. Maybe she finds out that she has a special connection to the Elder Wand that no one suspected before.
One idea could be exploring how the wizarding world rebuilds after the war. Harry, Ron, and Hermione could take on leadership roles in different aspects, like Harry in Auror training reform, Ron in Weasley's Wizard Wheezes expansion to help heal through humor, and Hermione in magical education reform to include more about Muggle - born history. Another could be a story about the next generation at Hogwarts, with Harry's kids and their friends facing new, non - Voldemort - related challenges but still learning from the past.
Well, in 'Harry Potter and the Deathly Hallows' fanfic, a great aspect is the expansion of the magical world. Writers can create new spells or magical creatures that fit within the Potterverse. They can also delve deeper into the politics of the wizarding world. How different wizarding families interact and their influence on the events of the story. Some fanfics might even change the outcome of certain battles, providing a fresh perspective on the whole story.
One interesting plotline could be exploring the untold stories of minor characters during the events of 'Harry Potter and the Deathly Hallows'. For example, how the students who stayed at Hogwarts coped with the final battle approaching. Another could be a different take on the search for the Horcruxes, perhaps with a new group of characters assisting Harry in unexpected ways.
One idea could be exploring what would happen if Neville Longbottom was the one who had to face Voldemort in the final battle instead of Harry. Another could be a fanfiction where the Deathly Hallows were discovered in a different order and how that changes the course of the story. Or perhaps a story about the Marauders' era characters influencing the events of the Deathly Hallows from the afterlife.
