Well, perhaps in the fanfiction, Harry becoming a werewolf leads to a rift between him and some of his friends who are afraid of him now. But then he meets other werewolves who teach him how to control his transformation and he uses this newfound control to his advantage in the fight against the dark forces. He could also form an alliance with the werewolves in the wizarding world, which changes the power dynamics.
One idea could be a werewolf character finding their true mate among the Harry Potter characters. Maybe a werewolf who has always felt like an outcast in the wizarding world finally meets someone who accepts them completely. This could lead to a story of self - discovery and acceptance for both the werewolf and their mate.
In this fanfiction scenario, Harry becoming a werewolf could cause a rift in the wizarding community. Some might see him as a threat, while others, like the Weasley family, would stand by him. The story could focus on how he copes with this new identity. He could start to understand the werewolves' perspective more, and try to bridge the gap between the wizarding world and the werewolf community. He might also have to deal with the Ministry of Magic's attempts to control or eliminate him because of his new form.
One plot idea could be that Harry discovers his Slytherin side is linked to a long - lost ancestor who was a great Slytherin wizard. This makes him question his identity and loyalty. Another could be that in Slytherin, he has to deal with the prejudice from the rest of the Hogwarts houses at first, but gradually changes their minds through his unique charm and skills.
One idea could be that Harry has to hide his new werewolf form from his friends at Hogwarts. He might struggle with the stigma associated with werewolves in the wizarding world, even though his friends know him well. Another could be that he discovers new magical abilities related to his werewolf form that help him in his fight against Voldemort. For example, enhanced senses that allow him to detect dark magic more easily.
One idea could be exploring how Harry copes with his new werewolf form at Hogwarts. Maybe he has to hide it from his friends at first and deal with the fear of being discovered. Another could be his interactions with other magical creatures who are more accepting of his werewolf side.
One idea could be that Harry has to hide his new werewolf form from his friends at Hogwarts. He might struggle with the monthly transformations and the fear of hurting those he loves.

One idea could be a Pokemon trainer who gets bitten by a werewolf-like Pokemon and starts to take on werewolf - like traits. They then have to struggle with controlling their new powers while still trying to compete in Pokemon battles.
One idea could be that the werewolf girlfriend has to hide her true nature from the human world but slips up during a full moon. Another could be a love triangle where a human and another supernatural being both vie for the werewolf girlfriend's affections. Or perhaps she's on a mission to protect her human lover from a rival werewolf pack.
A great plot for a Potter Manor fanfiction could involve a mystery that surrounds the manor. For instance, strange noises at night lead Harry to uncover a long - forgotten chamber. It could also be about Harry restoring the manor to its former glory, perhaps with the help of Hermione's research on ancient magic used in the construction of such manors.
One idea could be a character in the 'becoming human' universe discovers a hidden power within themselves. Maybe they can communicate with machines in a way no one else can, which leads to all sorts of adventures and challenges as they try to keep this ability a secret while using it to help others.
