In a fanfiction, the relationship might develop in an unexpected way. Harry Potter, who is used to the more 'normal' magical creatures, meets the succubus familiar. At first, he might be repelled by her nature, but gradually he discovers that there is more to her. They could bond over shared experiences in the magical world, like facing a common enemy. However, the relationship would always be on shaky ground due to the succubus's reputation and her own powers that could be both a help and a hindrance.
The development of their relationship would be a complex journey. Harry Potter is a character with strong moral values. Loving a succubus familiar would test those values. Initially, it could be a physical attraction that draws him to her. But as he gets to know her better, he realizes she has a soul and emotions too. They might have to overcome many obstacles, such as the wizarding society's view of such relationships, and the succubus's own in - built tendencies that could potentially harm Harry or those around him. It would be a relationship full of passion, conflict, and self - discovery for both Harry and the succubus.
In some fanfictions, their relationship might start with Harry being initially afraid or cautious of Hermione's new succubus form. But as he gets to know that she is still the same Hermione deep down, they start to build trust and their friendship evolves into something more, like a romantic relationship.
Well, perhaps the succubus could initially be a mystery to Harry. She might seem like an ordinary creature at first, but then he discovers her true nature. Maybe she helps him in some unexpected ways in his battles against Voldemort, like using her unique powers to distract the Death Eaters.
The relationship could start with Harry noticing fem Fawkes' unique beauty and grace. Since Fawkes has always been associated with Dumbledore, Harry could be initially curious about this female version. As they interact more, they could develop a mutual respect for each other's magical powers.
Maybe Fenrir saves Harry from a werewolf attack one night. Harry, being the empathetic person he is, doesn't immediately condemn Fenrir for his past actions. This small act of kindness from Fenrir plants the seed of a different relationship. They could start to exchange knowledge about magic and the dark forces in the wizarding world. As they get to know each other better, their relationship could evolve from a simple acquaintance to a friendship of sorts, with each learning from the other's experiences.
A succubus familiar can be incorporated by first establishing its magical nature. For example, it could have powers related to charm and allure, which are common traits of succubi. In a fanfiction, it might be a familiar that a dark wizard or an outcast wizard has. The succubus familiar could use its charm to help its master in various ways, like getting information from other characters or sneaking into restricted areas.
The main antagonist could be the Ministry of Magic if they view the succubus as a dangerous and uncontrollable creature. They might try to separate Harry from his familiar, and in the process, become the main force that Harry has to oppose.
At first, it might be a bit tentative. Harry has to earn Buckbeak's trust, just like in the original story. But as time goes on, they start to understand each other better. Buckbeak realizes Harry is different from other humans who might harm him, and Harry sees Buckbeak as more than just a magical creature.
At first, it might start with curiosity. Harry is used to his wizarding world, and the Muggle is something new. They might meet by chance, like in a park or a coffee shop. Then, as they get to know each other, they start sharing their different worlds. Harry might show the Muggle some simple magic tricks, and the Muggle might introduce Harry to Muggle hobbies.
At first, they might be cautious of each other. Aragorn, coming from a world of swords and battles, might not fully trust magic. Harry, on the other hand, might be wary of Aragorn's warrior - like nature. But as they face challenges together, they would start to respect each other. They could learn from one another's strengths, like Aragorn teaching Harry about physical endurance and Harry showing Aragorn the power of friendship and magic in a different light.
At first, their relationship would be full of mistrust. Harry is used to a world where people are generally more straightforward (compared to the backstabbing in Westeros), and Cersei would be skeptical of Harry's 'strange' magic. However, as they face challenges together, like threats from other kingdoms or magical creatures, they could start to rely on each other. Harry could teach Cersei about the value of friendship, and Cersei could show Harry how to navigate the complex political landscape of Westeros. Their relationship could gradually transform from a forced marriage to a more loving and understanding partnership.
