Hermione could be a potential rescuer. In a different timeline or scenario, she might stumble upon the abandoned Harry and use her intelligence and knowledge of magic to take care of him. Another could be Hagrid. He has a big heart and a love for all things magical. He might find Harry and take him under his wing, protecting him from any harm. And Sirius Black is also a possibility. Even if he was wrongly imprisoned, if he escaped earlier, he could be the one to rescue Harry and keep him away from the Dursleys.
Potential rescuers in such a fanfiction could include Luna Lovegood. She has a unique perspective on the world of magic. She might find Harry and introduce him to her own brand of magical thinking and lifestyle. Remus Lupin is also a good candidate. As a werewolf, he has known loneliness and could empathize with an abandoned Harry. He could take Harry under his protection and teach him about the darker sides of the wizarding world in a more understanding way. And what about Neville Longbottom? He could grow into a strong and confident wizard early on and be the one to rescue Harry, forming a powerful duo in the wizarding world.
Dumbledore could be a savior in this fanfiction. He has the power and the wisdom to step in and help Harry. He might have been waiting for the right moment to remove Harry from the Dursleys' influence. Also, there could be a new character, like an old and powerful wizard who has been in hiding but senses Harry's distress and comes to his aid. This wizard could have some unique magical abilities that can protect Harry and help him grow into a powerful wizard himself.
Some potential new allies could be the house - elves. They might see Harry's plight and decide to help him, using their unique magic and knowledge of Hogwarts' secrets. Another could be the centaurs in the Forbidden Forest. They are very wise and may take Harry under their wing.
Sokka might be a rescuer. He's Katara's brother and he would stop at nothing to save her. He could use his strategic mind and his trusty boomerang to take on the kidnappers. Another potential rescuer could be Zuko's uncle Iroh. He has great wisdom and his own firebending skills. He might be able to outwit the kidnappers and free Zuko and Katara. There's also the possibility of some unexpected characters from their past coming to their aid, like some of the Freedom Fighters they met earlier in their adventures.
The Blue - Eyes White Dragon could be an unexpected rescuer. In some fanfictions, the powerful card could come to life or have a spiritual connection to the Kaiba family. Also, an undercover detective who has been investigating the Kaiba family's enemies might be the one to rescue Mokuba. This detective could have been on the trail of the kidnappers for a while. And lastly, an old family friend or mentor of the Kaibas could emerge to save Mokuba. This person might have some special knowledge or skills that are crucial for the rescue operation.
There could be an American wizard who takes Harry under his wing, like a gruff but kind old wizard named Alistair. He could teach Harry about American magic in a no - nonsense way.
Hermione could be one. Given her open - mindedness and thirst for knowledge, she might be intrigued by the Demons Child and see its potential for good rather than just being scared of it.
Well, perhaps in this fanfiction, Harry is abandoned as a child and is then taken in by a dark wizard who has his own motives. Maybe the dark wizard wants to use Harry's fame to gain power in the wizarding world. Or it could be that Harry is abandoned and ends up in a parallel magical dimension where he has to find his way back to the normal wizarding world while learning new and strange magics. Another angle could be that he is abandoned and is found by a magical creature, like a centaur, who imparts wisdom and unique magical abilities to him.
Another possibility is that the heiress could be a new character entirely, created by the fanfiction author. She could be from a foreign wizarding family that has a claim to something in the British wizarding world. This new character could bring in different cultural elements of magic and challenge the traditional ways of the Hogwarts - centered wizarding society.
Well, Luna Lovegood could be a great ally for Harry. She has an open - minded and accepting nature. She might see something special in Harry even though he's been abandoned and would offer him her unique brand of friendship and support. Dumbledore, if he's still around in the fanfiction, would also be a key ally. He has a lot of knowledge and power and would likely take an interest in Harry's situation, guiding him and protecting him. And then there's the Weasley family. They are known for their warmth and kindness. Even if Harry is abandoned, they might take him in and be his family, with Ron being his closest friend among them.
Hermione Granger could also be a rescuer. She was always intelligent and resourceful. In a fanfiction, she might figure out that Harry was in danger at the Dursleys' through some research or a hunch. Then she could use her knowledge of magic to break into the Dursleys' house and get Harry out. She would be brave enough to take on such a task to save her friend.
