Perhaps in the story, the succubus has its own motives for allowing Harry to bind it. It could be seeking protection from some other more powerful entity. So the relationship between Harry and the succubus familiar is not just one - sided binding but a complex web of mutual needs and goals. Harry then has to navigate this relationship while also dealing with the reactions of his friends and the wizarding community who may be skeptical or even fearful of his new familiar.
The plot might involve Harry having to learn about the nature of succubi first. Since they are often associated with temptation and seduction in mythology. He has to overcome these aspects to truly bind the succubus as a familiar. This could lead to a series of internal struggles for Harry as he tries to maintain his moral compass while using the succubus's powers.
Well, it could be that Harry, in this fanfic, discovers a way to bind the succubus familiar through some ancient magic he stumbles upon. Maybe he needs its powers for a particular task, like fighting a new dark force in the wizarding world.
Maybe there's a demon lord who has some sort of claim over the succubus. This demon lord sees Harry's binding of the succubus as an insult and a threat, and thus becomes the main antagonist. He would then send his minions or use dark magic to try and break the bond between Harry and the succubus.
One possible plot could be that Harry, perhaps in a search for power or knowledge, binds the succubus. But then he has to constantly battle her wiles and temptations as she tries to break free. He might use magic he's learned at Hogwarts to keep her in check.
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.
Harry's character could become more cautious. Dealing with a succubus would make him realize that there are many dangerous and unpredictable forces in the magical world. He might also become more secretive as he doesn't want others to know about the succubus he has bound.
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.
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.
In such a fanfiction, it could be a very strange and unique scenario. Harry might face a lot of internal conflict. Loving a succubus, which is often associated with dark and alluring yet dangerous entities in mythology, would put him at odds with his normal values. He might struggle to reconcile his feelings for this otherworldly familiar while also trying to maintain his place in the wizarding world.
One possible plot could be that Harry, turned into a succubus, has to deal with new magical abilities and instincts. He might struggle to control his new form's allure and the power it gives him over others. For example, he could find that his presence now affects the emotions and actions of those around him in ways he didn't anticipate. This could lead to a whole new set of adventures as he tries to understand and master this transformation while still dealing with the threats in the wizarding world.
Well, it could be really interesting. A succubus is often depicted as a seductive and otherworldly being. In this fanfiction, perhaps the succubus familiar would help Harry in ways that are different from his normal magical friends. It might use its unique powers to assist him in battles, like confusing the enemies with its charm. Or it could also bring some chaos to Hogwarts as its nature might not always align with the school's rules.
Well, perhaps Harry discovers a magical creature in the Forbidden Forest that becomes his familiar. It could be a small dragon-like creature that only he can communicate with, and it helps him find hidden secrets in Hogwarts.
