What are some interesting plot ideas for 'Harry Potter and the Demons Child' fanfic?

One idea could be a story where a young wizard from the Harry Potter world accidentally travels to the Bleach universe. He could discover his newfound spiritual powers and try to find a way back home while getting involved in the battles against Hollows. Another plot could be a crossover where the Hogwarts houses are somehow related to the different Soul Reaper squads in Bleach. For example, Gryffindors could have an affinity with the more combat - oriented squads.

One idea could be that Harry discovers his connection to the demons due to an ancient family secret. Maybe his ancestors made a pact long ago. Another could be that he has to use his new 'King of Demons' powers to fight a dark wizard who is trying to control the demon realm for evil purposes. He could also face challenges within the wizarding world as they fear his newfound powers.

Hermione could be one. Given her open - mindedness and thirst for knowledge, she might be intrigued by the Demons Child and see its potential for good rather than just being scared of it.

One idea could be that Harry discovers he has a unique magical ability that even Dumbledore doesn't know about. This ability could be related to his connection with the very essence of magic. For example, he might be able to communicate with magical creatures in a way no one else can, which leads him to uncover secrets about Hogwarts' past.

One idea could be that the second child discovers a long - forgotten magic spell that has the power to reverse time briefly. This could lead to some interesting adventures where they try to correct past mistakes in the wizarding world. Another idea is that the second child has a special connection with magical creatures that no one else does, and they use this connection to solve a mystery involving a dangerous creature that is threatening Hogwarts.

One idea could be exploring the alternate timelines more deeply. For example, what if Voldemort had actually won in one of those timelines? How would the wizarding world look like? Another could be delving into the relationship between Albus and Scorpius in a more complex way, like their adventures outside of Hogwarts that test their friendship.

One idea could be that characters from Fma use their alchemical skills in the wizarding world of Harry Potter. For example, Edward could try to transmute a magical object using his knowledge of equivalent exchange. Another plot idea might be that the Philosophers Stone from Harry Potter has some connection to the alchemy in Fma, and characters from both universes have to work together to protect it from dark forces. Also, perhaps a character from Fma gets sorted into one of the Hogwarts houses and has to adapt to the magical school life while still having their own alchemical powers.

One idea could be that she has unique magical abilities due to her demon - raised upbringing. For example, she might be able to communicate with dark creatures in a way normal wizards can't. Another could be that she struggles with her identity, being part of the wizarding world but also having this demonic influence. She could also face a lot of prejudice from the wizarding community who fear her because of where she was raised.

One interesting plot idea could be exploring the alternate timelines more deeply. For example, what if the characters got stuck in a timeline where Voldemort had won? Another could be delving into the relationships between the next generation of characters in ways not fully explored in the original play. Maybe a story where Albus and Scorpius have to face a new dark wizard threat together, relying on their unique bond.

Well, in some fanfics, a plot twist might be that Voldemort has a secret heir who surfaces in the 'Cursed Child' era. This heir could initially seem like a villain but then has a change of heart due to interactions with the main characters. Also, there could be a twist where magic itself starts to malfunction in a way that no one expected, forcing the characters to find new ways to use their skills and knowledge. It could lead to some really creative solutions and alliances that were not possible before.
