There's a fanfiction called 'Unlikely Allies'. It's about fem Harry who is on the run from some dark wizards and stumbles into the Inuyasha realm where she meets Sesshomaru. At first, they are at odds with each other but as the story progresses, they start to understand and respect one another. The story is full of adventure and the way the two characters from different universes interact is quite engaging.
If Sesshomaru were Fem Harry Potter's father, their relationship would diverge greatly from the norm. Sesshomaru is not used to the social norms of the wizarding world. He would likely raise Fem Harry Potter with a sense of pride and independence that is different from the Potter family. His knowledge of different types of magic, from his own world, could influence Fem Harry Potter's understanding of magic. Also, his cold exterior might hide a deep - seated protectiveness towards his daughter. This could lead to a relationship where Fem Harry Potter has to earn his respect, and in turn, he would bestow upon her great power and knowledge when she proves herself.
She might inherit enhanced physical abilities like superhuman strength, speed, and agility. Sesshomaru is a very powerful demon, so Fem Harry Potter could also have the ability to sense other magical beings from a distance. And perhaps she could inherit some of his demonic energy which could be used to enhance her spells or protect herself in a different way than normal wizarding magic.
Yes, there could be such fanfictions in the vast world of fan - created content. Writers often come up with creative crossovers and unique family relationships in fanfiction. However, I haven't specifically read one with this exact premise, but it's very likely to exist given the popularity of both the Harry Potter series and Loki as a character.
One possible plotline could be that the female Harry Potter, through some magical accident or spell, ends up in the world of Inuyasha where she meets Sesshomaru. Their initial interactions might be full of mistrust, but as they face common enemies or challenges, they start to develop feelings for each other.
The popularity of fem Harry and Sesshomaru fanfiction lies in the contrast between the two characters. Harry, with her magical abilities from the wizarding world, and Sesshomaru, a powerful demon from the Inuyasha universe, create a really interesting dynamic. Their different power sets and personalities make for a lot of exciting story possibilities. For example, how would Harry's spells work against the demons Sesshomaru knows? And how would Sesshomaru react to Harry's unique brand of magic? These questions draw readers in.
I'm sorry, I'm not aware of any specific 'fem Harry Potter mated to Sesshomaru' fanfics. You could try searching on popular fanfic websites like Archive of Our Own or FanFiction.net.
A third plotline could center around the challenges they face as a couple. There could be opposition from both their respective worlds. In Harry's world, the wizarding community might not understand her relationship with a non - human from another realm. In Sesshomaru's world, demons might have their own opinions about a human - like Harry being his mate. This could lead to many conflicts and a journey of them trying to be together despite all the odds.
One common theme is the clash of two different worlds. Harry Potter's magical world and Sesshomaru's demon - filled world often collide, leading to interesting power dynamics and cultural differences.
There are quite a few out there. Some might focus on a crossover where Sesshomaru somehow ends up in the Harry Potter world, perhaps with his demon powers causing all sorts of chaos or him teaming up with the Hogwarts students against a common enemy. You have to dig a bit through different platforms to find the really good ones.
