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.
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.
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.
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.
In some fanfictions, the Black Shuck could be a guardian of a hidden magical artifact. It's a fearsome beast that wards off those unworthy of approaching the powerful item. Maybe it has a connection to an ancient wizarding family, and only a descendant of that family can communicate with it or pass by it without being attacked.
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 possible storyline could be a female Harry Potter having to work with Lucius Malfoy in a situation where they have to put aside their differences. For example, in a magical crisis that threatens the entire wizarding world. Maybe they start off distrusting each other but gradually come to respect one another as they realize they both have unique skills and knowledge that can help solve the problem.
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.
One idea could be to have the characters from Harry Potter end up in the Pitch Black universe. Maybe Harry and his friends could be stranded on a planet like in Pitch Black and have to deal with the dangerous creatures there while also using their magic in unique ways. For example, using Lumos to fend off the Pitch Black creatures in the dark.
In this type of fanfiction, the idea of magic itself evolving in the pitch - black setting is fascinating. Maybe the magic that is related to light, like Lumos, has been corrupted or weakened. So, wizards and witches have to rely on other types of magic, like magic that senses the environment or magic that can create a form of sonar - like effect. This would force the characters to re - evaluate their understanding of magic and adapt to this new, darker magical reality.
Well, there could be a story where Hermione discovers a hidden diary of Lily Potter. As she reads it, she starts to adopt some of Lily's characteristics and wisdom. This could lead to her becoming a more empathetic and powerful witch, and also might help her in her relationships with Ron and Harry. In a different plot, Hermione could be magically transformed to look like Lily for a special mission, and during that time, she experiences the world from Lily's perspective, which changes her in many ways.
