A possible plot for 'Harry Potter mob boss fanfiction' could be that a former Death Eater who survived the war decides to create his own criminal empire. He recruits other disgruntled wizards and witches who feel they were wronged after the war. Harry, now an Auror, has to go undercover to gather evidence against this new mob boss.

One idea could be that Bella is a journalist trying to expose Edward's mob activities, but she ends up falling for him instead. Another could be Edward protecting Bella from rival mobsters when she gets caught in the crossfire of his underworld business. A third plot could be that Bella is a singer in a club owned by Edward's mob and they develop a relationship through her performances at his establishment.
One plot idea could be that the mafia boss is secretly protecting Hogwarts from a new dark threat. He uses his underworld connections to gather information that the Ministry of Magic can't access. For example, he might discover a group planning to steal powerful magical artifacts from the school. Another idea is that the mafia boss is actually a wizard who was exiled from the wizarding world long ago and has built his own criminal empire in the Muggle world. But when he hears about Voldemort's return, he decides to use his resources to help Harry Potter, in his own unorthodox way. A third idea could be that the mafia boss has a vendetta against a Death Eater who once wronged him in the past, and he teams up with Harry and his friends to take the Death Eater down.
Well, the character dynamics in such a 'harry potter mob boss fanfic' can be really engaging. Imagine a character like Draco Malfoy as a mob boss. His family's influence and his own Slytherin cunning could be played up to create a complex power - hungry character in this new setting. Also, the relationships between different houses might change. Instead of just school rivalries, they could turn into territorial or power struggles within the mob world.
One possible plotline could be Harry taking over the wizarding underworld after defeating Voldemort. He might use his fame and the loyalty of his friends to start building his own 'empire'. He could control the trade of magical items and potions, similar to how a mob boss controls illegal trades. Another plotline could be Harry being born into a mob - like wizarding family instead of the Dursleys, and growing up learning the ways of the wizarding underworld from a young age.
One plot idea could be that Harry, as the mafia boss, is trying to keep his identity a secret from the wizarding world while Daphne accidentally discovers it. She then has to decide whether to expose him or join his cause. Another could be that they team up to take down a common enemy in the criminal underworld of the wizarding community. Maybe there's a dark wizard who is threatening both Harry's mafia operations and Daphne's family business, so they form an alliance and in the process, develop romantic feelings for each other.
In this fanfiction, the plot might revolve around Harry's transformation into a mob boss during time travel. He could discover that the wizarding world has a seedy underbelly that was hidden from him before. Harry may start to use his magic in new and unethical ways to gain power. He might face challenges from other powerful wizards who don't want a new player in the mob scene. His friends, like Hermione and Ron, could be conflicted about whether to support him or try to stop his descent into the dark side of the wizarding world.
Voldemort could be a very likely mob boss character. He already has an army of Death Eaters and is used to ruling with an iron fist. His thirst for power and lack of regard for the rules of the wizarding world would make him a very menacing mob boss in this type of fanfic.
A crossover with Jujutsu Kaisen would also be cool. Mob and Yuji could team up against curses. Since Mob has such strong psychic powers and Yuji has his physical strength and Sukuna's power, they could combine their abilities in unique ways. For example, Mob could use his psychic powers to hold a curse in place while Yuji delivers a powerful physical blow.
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 interesting plot idea could be exploring what would happen if Harry had a different upbringing, like being raised by the Malfoys. It would completely change his view of the wizarding world and his relationships. Another idea might be a time - travel fanfic where Harry goes back to the Marauders' era and interacts with his parents and their friends. This could lead to him preventing certain tragedies or changing the future in unexpected ways. And then there's the concept of a fanfic where the roles are reversed, and Voldemort is the one trying to protect the wizarding world from a greater evil, with Harry being the main antagonist.
