The main plot could revolve around Fem Harry's unique bond with Teddy. Since she's raising him alone, she pours all her love and energy into him. Teddy might start to show signs of powerful magic early on, and Fem Harry has to figure out how to guide him. This could lead to adventures where they discover new spells or magical artifacts together.
One possible main plotline could be Fem Harry struggling to balance her own life and the responsibilities of raising Teddy. Maybe she has to deal with financial difficulties while also making sure Teddy gets a proper magical education. She might face judgment from the wizarding community for being a single mother figure at a young age.
She would probably start by teaching Teddy basic magic at home, like how to make a feather float or how to use a simple charm. Since she has her own experiences at Hogwarts, she'd know what's important for a young wizard to learn early on.
One possible plotline could be how Harry and Hermione adjust to their new roles as parents. They might face challenges like Teddy having magical outbursts due to his young and powerful magic. For example, Teddy could accidentally transform objects in the house when he gets excited or scared. Another aspect could be Teddy's education. Harry and Hermione would surely want to give him the best magical education, so they might start teaching him basic spells at a very young age. They could also introduce him to the wizarding world's history and culture, taking him to places like the Ministry of Magic to show him how things work.
Perhaps Walburga realizes that Harry is the key to changing the wizarding world for the better. She could start teaching him about the history of the Black family, both the good and the bad, and together they could work towards a more inclusive and less prejudiced wizarding society. This would be a major shift for her as she comes from a family with a lot of dark and prejudiced views.
One possible plotline could be that fem Harry is intrigued by Orochimaru's unorthodox and powerful jutsu. She might start to study his techniques secretly, seeing them as a way to gain power to protect herself in the dangerous wizarding world. This could lead to her getting into trouble as Orochimaru's methods are often considered dark and unethical in the context of the magical world.
One possible plotline could be Bellatrix trying to mold Harry into a dark wizard. She might use her knowledge of the Dark Arts to teach him, but Harry resists. Another could be that Bellatrix starts to have a change of heart while raising Harry and begins to question her loyalty to Voldemort. Maybe she sees something in Harry that reminds her of a better part of herself.
A possible plotline could involve Fem Ichigo being a huge Harry Potter fan in her world, and she writes fanfiction about it. But then, magically, the characters from her fanfiction come to life in her world. Harry and his friends are confused about this new world, and Fem Ichigo has to help them adjust while also trying to figure out how this happened. They might also encounter villains from both universes who team up, forcing them to work together to defeat the combined threat.
In a Naruto - raises - Gaara fanfiction, Naruto could help Gaara deal with his inner demon. Gaara has had a tough time controlling Shukaku, his tailed beast. Naruto, who has also had to deal with the power of the Nine - Tails, could offer advice and support. He might teach Gaara some of the meditation techniques he used to keep the Nine - Tails in check. This would lead to Gaara having better control over his powers and becoming a more stable and powerful shinobi. Also, Naruto could help Gaara improve his relationship with the people of Suna. Given Naruto's charm and ability to make friends, he could show Gaara how to win the trust and love of his own villagers.
One idea could be Teddy Lupin having trouble adjusting to Hogwarts due to his unique situation, and Harry helps him navigate the challenges. Harry could share his own experiences of feeling out of place as a young wizard. For example, Teddy might struggle with his Metamorphmagus abilities and Harry, having faced many odd situations himself, gives him advice on how to control it and not let it make him stand out too much in a negative way.
In this fanfiction, a plot could be Teddy getting into trouble with the Ministry of Magic for some accidental magic gone wrong. Harry has to use his influence and experience to get Teddy out of the situation. Along the way, they could bond over their shared experiences of being different in the wizarding world. Harry could also introduce Teddy to his friends from the old days, like Hermione and Ron, and Teddy could learn valuable life lessons from them. This would not only strengthen their relationship but also help Teddy grow as a person and a wizard.
In some fanfictions, there might be a plot where Teddy gets into trouble at Hogwarts. Harry, as a sort of mentor figure, steps in to help him out. This could lead to a strengthening of their bond as Harry defends Teddy and teaches him the right way to handle the situation. Maybe Teddy was wrongly accused of using dark magic, and Harry uses his experience to prove Teddy's innocence.
