Perhaps a storyline where Fem Harry discovers a connection between the magic in the Harry Potter world and the arcane powers in Warhammer. She could then embark on a journey to understand this connection better, facing challenges along the way. She might meet characters from both universes who either help or hinder her in this quest, making for a very engaging fanfiction.
Well, in some fanfictions, Fem Harry might find herself in the middle of a conflict between different factions in the Warhammer universe. Her loyalty to her friends from the Harry Potter world could translate into forming alliances in Warhammer. Maybe she teams up with some of the more noble - hearted groups in Warhammer, using her quick thinking and magical abilities to help them in battles, much like she did against Voldemort and his Death Eaters in the original Harry Potter series.
One interesting storyline could be how Fem Harry Potter's magic interacts with Madara Uchiha's Sharingan abilities. Maybe her magic could enhance or disrupt the power of the Sharingan in unexpected ways. Another could be their cultural clashes, as Harry comes from the wizarding world and Madara from the ninja world. They might have different values and ways of doing things, which could lead to both conflict and growth as they learn from each other. Also, a possible plot could involve them teaming up against a common enemy that threatens both their worlds, like a powerful dark force that combines magic and ninja techniques.
One of the most interesting storylines could be a dragon handler who discovers a new breed of dragon in the Forbidden Forest. This could lead to a whole adventure of trying to keep it a secret from the Ministry of Magic while also learning about its unique abilities. Another could be a dragon handler who has to deal with a dragon that has been poisoned, and they have to find a cure using their knowledge of both magic and dragon physiology. Maybe a dragon handler who forms a special bond with a dragon and uses that bond to help in the war against Voldemort, like using the dragon to transport crucial supplies or even fight in battles.
In some pitch - black Harry Potter fanfictions, there might be a storyline where Voldemort actually had a valid reason for his actions, at least from a certain perspective. It could explore how the wizarding society's discrimination and power - hungry nature drove him to the dark side, and Harry has to grapple with this new understanding. Also, a story could involve Harry being corrupted by the power he holds, turning him into a much darker character than we know from the original books.
One interesting storyline could be how Harry Potter's experiences with death and his mastery of it influence Tsuna in a new magical world that combines the universes. Maybe Harry teaches Tsuna some of his unique magical skills related to death, like communicating with the dead, which could be used in Tsuna's battles against his own foes.
One interesting plot twist could be that Fem Harry Potter, with her magic skills, ends up changing the power dynamics in the Highschool DxD world. For example, she might introduce new spells that disrupt the existing balance of power among the various factions. Another could be that she has a hidden connection to one of the powerful characters in Highschool DxD, like a long - lost relative or something. This would lead to a whole new set of relationships and storylines. Also, perhaps her presence causes the different species in Highschool DxD to reevaluate their views on magic, as her magic might be different from what they are used to.
One interesting storyline could be a hybrid character struggling to find their place in the wizarding world. They might be shunned by both vampires and werewolves, yet possess unique powers that could be useful in the fight against dark magic. For example, their vampire side could give them enhanced speed and strength, while their werewolf side might offer a connection to nature that helps in certain spells or potions. Another could be a love triangle between a vampire - werewolf hybrid, a pure - blood wizard, and a Muggle - born witch, exploring themes of prejudice and acceptance in the magical community.
The contrast between their characters. Harry, even as a female, is a magical being full of wonder and potential, while Vernon is a very mundane and often narrow - minded Muggle. This creates a lot of interesting conflict and opportunities for unique storylines.
The plot where Murtagh teaches Harry some of his unique magic techniques is really cool. It shows how different magical systems can interact. For example, in a fanfic I read, Murtagh showed Harry how to use a spell that was common in his world but unheard of in Hogwarts.
In the fanfiction, Fem Harry may be more assertive compared to the original male Harry. In the Harry Potter world, she might break more gender - related norms. In Warhammer, this assertiveness could translate into her being a more fearless fighter or leader. For instance, she may not shy away from leading an army in Warhammer, while the original Harry was more focused on individual battles in Hogwarts.
