In this fanfiction, perhaps Harry has some unique abilities that set him apart as a bounty hunter. He could have a special tracking sense or be an expert in hand - to - hand combat. His adventures might take him to different planets or hidden dimensions where he has to face all kinds of strange and menacing foes.
Another could involve a bounty hunter who has a personal vendetta against a group of Death Eaters. This hunter might team up with Harry Potter and his friends, bringing in their own set of skills and knowledge about the underworld of the wizarding world. They could be really good at disguises and infiltrating Death Eater hideouts. For example, they might use a special potion to change their appearance and blend in with the bad guys to gather information.
One idea could be a bounty hunter who is initially after a character from RWBY but then discovers they are on the wrong side. For example, hunting Ruby at first because she's thought to be a dangerous criminal, but as the story unfolds, realizes she's actually a hero. Another idea is a bounty hunter who has a special weapon or power unique to the RWBY universe, like a weapon that can transform into different types of dust - powered tools. A third idea could be a bounty hunter who teams up with the RWBY gang to take down a greater threat, like a powerful and elusive criminal organization.
One idea could be a bounty hunter who is tasked with tracking down a dark wizard who has escaped from Azkaban and is hiding in the Muggle world. The bounty hunter has to use both magic and knowledge of Muggle ways to find the wizard.
Well, think about a story where the Force in Star Wars is combined with magic from Harry Potter. A bounty hunter could be caught in the middle of this power struggle. Maybe a wizard - turned - bounty - hunter has to use both magic and his blaster to complete his missions. Or perhaps a story where the Death Eaters are somehow involved in the bounty hunting business in the Star Wars galaxy, bringing their dark magic to a new and unfamiliar place.
Well, perhaps Harry could be hunting down dark wizards who have escaped from Azkaban and are causing chaos in the wizarding world. He might use his skills from his battles against Voldemort, like his knowledge of spells and his ability to think on his feet.
One common theme is empowerment. Since Harry is female in these fanfics, it often shows her breaking gender norms in the bounty hunting world. Another theme is adventure, as she goes on various bounty hunting quests. And of course, there's often a theme of self - discovery as she learns more about herself through her experiences as a bounty hunter.
The fanfiction might also introduce some side characters that add flavor to the story. For instance, a bar owner in a seedy part of town where bounty hunters gather. This character could be a source of information for Harry, providing him with leads on his targets. Or it could be a mechanic who keeps Harry's transportation in working order, and they might have some interesting conversations during the repair sessions.
Another interesting plot point is the power struggle. In some fanfics, the bounty hunter might be very powerful in their own universe, but in the Harry Potter world, there are powerful wizards and dark forces. How they navigate this new power hierarchy, whether they try to dominate or find a place within it, makes for a great story. Also, the idea of a bounty hunter having to deal with the Ministry of Magic's laws and regulations which are very different from the lawless areas they might be used to in Star Wars is really engaging.
One interesting story might be about a bounty hunter's encounter with a powerful Sith Lord. The bounty hunter has to use all his skills to survive.
One famous bounty hunter story is about Boba Fett. He was hired to capture Han Solo. Boba Fett was known for his fearsome reputation and his Mandalorian armor. He managed to track Solo down and deliver him to Jabba the Hutt, which led to a whole series of events in the Star Wars saga.
