The story could start with her discovery of her true parentage. Maybe she's raised in the wizarding world as a normal witch, but then something happens that reveals she's Ganondorf's daughter. This could lead to her being ostracized or feared by some in the wizarding community. Meanwhile, she has to figure out how to control the dark powers that start to surface within her, all while trying to fit in at Hogwarts and deal with Voldemort's threat as well.
It could also be that Ganondorf has some grand plan for his daughter in the wizarding world. He might be using her to gain access to the powerful magic there or to cause chaos. Fem Harry would then be caught in the middle, not fully understanding her father's motives but feeling some sort of loyalty or connection to him. She would have to make choices about which side she's on, and how she can use her unique abilities to either save or destroy the wizarding world.
Well, another option could be to check out some Harry Potter and Legend of Zelda fan communities. These communities often have members who share or recommend interesting fanfictions. Maybe post a request in those groups asking if anyone has come across such a story.
One possible plot could be that she discovers her divine heritage while at Hogwarts. Maybe she starts to show powers that are a mix of wizardry and godly abilities, like being able to control the weather during a Quidditch match. This would cause a stir among the students and teachers alike.
The plot might involve her struggling with her identity. On one hand, she's a part of the wizarding world like Harry was, but on the other, she has this dark and powerful heritage from Thanatos. She could be shunned by some in the wizarding community because of her connection to death. As she grows up, she discovers secrets about her father's realm and how it relates to the dark magic that Voldemort was seeking. This could lead to her being both a target and a potential savior in the fight against evil. And throughout the story, she has to learn to balance her two sides, the magical side from her mother (presumably Lily) and the death - related powers from her father.
Well, it could involve Harry having special powers inherited from Celestia. Maybe she can control celestial elements like stars and moons. Her relationship with other characters would also change. For example, Dumbledore might treat her differently knowing her divine origin. And she could face new enemies who are after her because of her connection to Celestia.
Perhaps the main plot could be about her search for a sense of identity. She doesn't fully belong in either the world of the Norse gods or the Harry Potter wizarding world. She has to navigate through different cultures, magic systems, and social norms. Along the way, she meets various characters who help or hinder her in this quest for self - discovery.
One plot idea could be that as the daughter of Ares, she has an inborn combat prowess. She could use her skills from the wizarding world, like magic, combined with her Ares - given strength and aggression in duels at Hogwarts. Maybe she gets into conflicts with the traditional pure - blood families who look down on her 'un - wizard - like' aggressive fighting style.
Maybe Ganondorf adopts Fem Link in an attempt to break the cycle of their eternal struggle. He hopes to raise her to be different from the typical hero. As Fem Link grows, she discovers her true identity and has to grapple with her loyalty to Ganondorf, who has been like a father to her, and her destiny as the hero. Along the way, she might meet other characters from the Zelda universe who try to sway her in different directions.
Well, perhaps it could start with Harry, now a female, being magically transported to the Black Butler universe. Ciel discovers her and realizes she has some strange powers similar to those in his world. As his daughter, she might be involved in solving the mysteries and dealing with the dark forces in Ciel's world while also trying to figure out how she got there.
One possible plot could be that Fem Harry Potter discovers her true parentage as she grows up in the wizarding world. This revelation could cause chaos as she tries to understand her place between the two very different worlds. She might have to learn about her Norse powers in addition to her magic, and face challenges from both sides.
Well, perhaps the female Harry Potter uses her magic skills in the world of being a hitman. She could be using spells to outwit her targets or to make her escapes. Maybe she has a special wand that she uses as a weapon in a more non - traditional hitman way.
