Well, perhaps the most interesting plot point would be Harry's journey to become a pirate lord. Maybe he starts off as a stowaway on a pirate ship, discovers his latent magical abilities can give him an edge in the pirate world, and gradually rises through the ranks. Also, his encounters with magical artifacts hidden in the pirate coves and how he uses them to his advantage would be really cool. There could also be a plot point where he has to face off against dark wizards who have also infiltrated the pirate world.
In this fanfiction, perhaps a major plot point is Harry using his new position to reform Azkaban. He could introduce new ways of dealing with prisoners that are more humane. Also, his power might attract the attention of dark forces who want to either use him or destroy him, which would add a lot of action and suspense to the story.
One idea could be a pirate crew made up of Hogwarts students who go on a quest to find a magical treasure hidden by an ancient wizard - pirate. They'd use their magic in unique ways on the high seas. Another could be a story where Harry discovers a long - lost relative who was a pirate and inherits a magical pirate ship. The ship has its own secrets and powers.
One interesting plot point could be Harry helping the goblins in a rebellion against the wizarding world's unfair treatment of them. Another could be him learning goblin - made magic that is different from what he learned at Hogwarts. Maybe he discovers a hidden goblin treasure that has a powerful magical item and has to protect it from dark wizards.
A great plot point might be Arwen's perspective on the concept of magic in the Harry Potter universe compared to that in Middle - earth. Since she has a different understanding of magic, her reactions and interactions with the wizards could be really fascinating. For instance, she might be surprised by some of the more 'brute - force' spells used in the wizarding world, while the wizards might be in awe of her more subtle and nature - based elven magic. Another interesting aspect could be if Arwen gets involved in the fight against Voldemort. Her elven wisdom and powers could potentially change the course of the battle in unexpected ways.
Often, a key plot point is Fem Harry's self - discovery. She realizes she can be more than just a Potter. For example, she might find new magical abilities that the Potters were not known for. Another plot point could be her making new relationships. Since she's not bound by the Potter name, she can form friendships with people who would have otherwise been off - limits due to family feuds or alliances related to the Potters. Also, her forging a new identity in the wizarding world is a big plot point. She might choose a new name or a new area of study that has nothing to do with the Potter family traditions.
A common interesting plot point is the clash of cultures. Shego comes from a different fictional universe with different values and abilities. When she enters the Harry Potter world, her reactions to things like magic spells, magical creatures, and the strict hierarchy of the wizarding world can create really engaging storylines. For example, she might be completely unimpressed by the concept of house - elves, which could lead to some funny or thought - provoking situations.
In some 'Harry Potter air elemental fanfiction', a plot point might be that the air elementals are actually the descendants of an ancient wizarding group. Their powers are slowly awakening in the modern wizarding world, and Harry and his friends have to figure out how to deal with this new element in their world. This could involve learning about new types of magic related to the air element and facing enemies who want to use the air elementals for their own evil purposes.
Character relationships are key too. Imagine the friendship or rivalry between Harry Potter and Batman. Harry, who has grown up in a world of magic, and Batman, who has seen the worst of the human world. Their different outlooks on life and how they might influence each other can be really engaging. Also, the reactions of other characters like Hermione and Robin to this unlikely pairing are often explored in these fanfictions in very interesting ways.
Well, there are several. The idea of Dexter being exposed to magic for the first time can be really fascinating. How would he react to spells and potions? Another plot point could be the wizarding world's reaction to Dexter's methods of dealing with 'bad guys'. They might see it as a form of dark magic in their own right. And then there's the potential for Dexter to discover some hidden secrets in the wizarding world that are related to his own past or his 'dark passenger' that could change everything he thought he knew.
There could be a really interesting plot where the werebear nature of Harry Potter in the fanfiction is a closely guarded secret. He has to struggle with hiding this new aspect of himself while also dealing with his regular Hogwarts life. He might face challenges like accidental transformations during full moons and having to cover it up from his friends. And maybe the werebear side of him has a connection to an ancient prophecy in the wizarding world that only he can fulfill.
