The forgotten twin could be found to have a hidden prophecy related to them. Similar to Harry's prophecy, but with a different outcome or role to play. This could cause a stir in the wizarding world as everyone tries to figure out what the twin's true purpose is. It might also lead to a power struggle between different factions who want to either protect or use the twin for their own gains. The twin would then have to navigate through this complex web of politics and magic while also dealing with their new - found identity.
Perhaps the forgotten twin has a connection to Voldemort that Harry doesn't. Maybe they share some of Voldemort's memories or powers due to a strange magical accident during their birth. This would create a lot of internal conflict for the twin as they struggle with their identity. They might be feared by the other students at Hogwarts, thinking they could be a new threat. It could also lead to a situation where the twin has to prove their loyalty to Dumbledore and their friends, and in the process, discover new ways to use their unique connection to fight against Voldemort.
One interesting plot twist could be that the forgotten twin has a different magical ability than Harry. For example, while Harry is good at Defense Against the Dark Arts, the twin might be a natural at Potions or Charms. This could lead to a situation where the twin is initially seen as an outcast in Hogwarts because their skills don't match the typical Gryffindor traits. Another plot twist could be that the forgotten twin was actually hidden away by a powerful dark wizard who planned to use the twin's power for their own evil purposes. This would put the twin in a difficult position when they discover their true past and have to decide whether to side with the forces of good or be influenced by the dark wizard's plans.
Perhaps a plot twist where the dark magic that was thought to be vanquished resurfaces in a new form. The fanfic might explore how the wizarding world, still recovering from the war, has to deal with this new threat. It could be that old spells are combined in new and dangerous ways by a group of rogue wizards.
One interesting plot twist could be that the basilisk has an unexpected ally. Maybe a house - elf that has been secretly communicating with it for some reason. This would completely change the dynamic as it adds an element of mystery and betrayal within Hogwarts.
In some 'Harry Potter and the Dursleys' fanfics, there's a plot twist where the Dursleys are actually protecting Harry from a greater threat that the wizarding world doesn't even know about. They've been cruel to keep him close and safe. Also, there could be a twist where Vernon Dursley has a connection to the wizarding world through his family's past that he's been trying to hide all along, which changes how we view his hatred for magic.
Well, perhaps in the 'harry potter in the order fanfic', a major character's magical ability is suddenly revealed to be much different than what was originally thought. Like Hermione, who was always known for her book smarts, might have a hidden and extremely powerful combat - based magic that gets uncovered during a crucial battle. This would completely change the dynamics of how she is perceived within the Order and how she can contribute to their cause.
Well, perhaps the gamer is transported into the Harry Potter world at a crucial moment, like during the Battle of Hogwarts. But instead of just joining the fight as expected, they discover a hidden passage in the castle that leads to a powerful magical artifact that can turn the tide of the battle in a very unexpected way.
In the 'Harry Potter and the Twists of Fate Fanfic', a possible plot twist could be that the way magic works is suddenly changed. Maybe spells that were thought to be dark are actually the key to solving a great mystery. This would force the characters to re - evaluate their understanding of magic and their place in the wizarding world. It would also create new challenges and opportunities for the characters, leading to a whole new set of adventures and conflicts.
One possible plot twist could be that the twin brother has different magical abilities. For example, while Harry is known for his proficiency in Defense Against the Dark Arts, his twin could be a natural at Transfiguration. This would create an interesting dynamic as they could learn from each other in different ways. Another plot twist might be that the twin brother is initially hidden away for some mysterious reason, perhaps related to a prophecy that involves both of them. When he finally appears, it throws the wizarding world into chaos as everyone tries to figure out what his role is. And a third plot twist could be that the twin has a connection to Voldemort that Harry doesn't. Maybe he was unknowingly marked by Voldemort in a different way, leading to a race against time to figure out how to break that connection and save him.
One interesting plot line could be how the twin's presence affects Harry's relationships at Hogwarts. Maybe the twin has a different personality and befriends characters that Harry doesn't usually interact with much, like some of the Slytherins. This could lead to a whole new set of adventures and alliances within the school.
One interesting plotline could be the twin sister having hidden magical powers that are different from Harry's. For example, she might have an affinity for ancient spells that have been long forgotten in the wizarding world. Another could be that she was separated from Harry at birth due to a prophecy that the dark forces were after her specifically, and she grows up in a different magical community, unaware of her true identity until later in the story.
One idea could be a crossover where Harry Potter characters are transported to the Forgotten Realms. They could encounter different magical creatures there, like beholders or mind flayers. Harry might use his skills to deal with the new threats.
