In this fanfic, the plot could center around Harry's identity crisis. He's adopted by wolves, so he has this wild, untamed side, but he also has his wizarding roots. He might struggle to fit in when he finally enters the wizarding world. The wolves could have taught him a different moral code, and he has to reconcile that with the rules and values of Hogwarts. This internal conflict could drive the story forward, with him making new friends who either accept or reject his wolf - like qualities.
Well, perhaps in the fanfic, Voldemort has somehow found a way to cross over into Kim's world too. Harry, now adopted by Kim, has to protect both his new family and this new world. Kim and her friends are initially skeptical about Harry's magic but soon realize how useful it can be. They start training together, with Kim teaching Harry some of her combat moves and Harry showing her the basics of magic. This way, they combine their skills to face the threat of Voldemort and his new minions in this strange new world.
One possible plot could be that Marge, despite her initial rough exterior, discovers a soft spot for Harry. She might start to teach him some of her own values, which could be a mix of traditional and rather strict ones. Harry would have to adjust to living in a new environment with Marge's dogs and her no - nonsense attitude.
It could be that the wolves are actually magical wolves with special powers. They sense Harry's unique magic and choose to protect him from the threats he faces in the wizarding world. Harry, while being adopted by them, might discover new forms of magic that are related to nature and the wild, which are different from what he learns at Hogwarts.
One possibility is that Umbridge, despite her cruel nature, sees some potential in Harry for her own gain. Maybe she tries to mold him into a perfect little wizard according to her strict and often wrong ideas. She could isolate Harry from his friends and force him to follow her rules blindly, which would create a lot of internal conflict for Harry as he tries to resist her brainwashing while living under her roof.
In a 'Harry Potter adopted by Newt' fanfic, perhaps Newt gets a mysterious message about a powerful but troubled young wizard. When he finds Harry, he realizes that the boy has a connection to the magical creatures world that he doesn't yet understand. Newt takes Harry under his wing. Harry gets to live in Newt's home, which is filled with all sorts of amazing and dangerous creatures. He learns about their habitats, behaviors, and how to communicate with some of them. This knowledge and his bond with Newt could change the way he approaches challenges at Hogwarts and in the wizarding world as a whole.
One possible plot could be that Gibbs helps Harry uncover some secrets about his parents that even the wizarding world doesn't know. Since Gibbs is a master at investigating, he could use his skills to dig into the past. Maybe there are some hidden connections between Harry's family and some muggle affairs. Harry, under Gibbs' guidance, could start to see the wizarding world from a different perspective, combining the practical thinking of Gibbs with his own magical abilities.
In this fanfiction, it could be that the king is from an ancient line of wizards that have long been in hiding. When he adopts Harry, he reveals to Harry the true history of magic, which has been distorted over time. Harry then uses this knowledge to find new and powerful magical artifacts that help him defeat Voldemort once and for all. The king also provides Harry with a new family and a sense of belonging that he never really had at the Dursleys'.
The plot could involve Rebbekah protecting Harry from the threats in the wizarding world. Since she has her own set of powers and a rather fierce nature, she'd be a great guardian. Harry, on the other hand, might struggle with adapting to her family's way of life. There could be conflicts within the Meakelson family about Harry's presence too. Some might see him as an outsider, while others might see potential in him, which would create a lot of interesting drama and storylines.
Perhaps he's adopted by a family of house - elves. They teach him their unique brand of magic that is more about domestic and hidden spells. Harry would then have a different perspective on the wizarding world, seeing it from the eyes of those who serve. He could also use this knowledge to help other house - elves gain more rights later on.
The plot might start with Harry being in a vulnerable situation and the Cullens taking him in. They'd have to figure out how to raise a wizard in their vampire household. Harry could start to show his magical abilities which might be both a wonder and a bit of a problem for the Cullens. He could also make new friends in the vampire community, and together they could face some common enemies.
