In a fanfiction where Harry Potter meets King Arthur, there could be a magical exchange of spells and swordsmanship. Harry might show King Arthur some of the modern magic from his world, like the Patronus charm. Arthur, in turn, could teach Harry about the code of chivalry and the art of sword fighting. Maybe they would team up to fight a common enemy, using a combination of magic and medieval combat skills.
The magic of apparition and disapparition could be a huge addition. Although it might be a bit difficult to master in a new magical environment, if Harry could use it, it would change the way battles are fought or how people travel in King Arthur's world. It could be used for surprise attacks or quick escapes. Also, the magic of the Marauder's Map could be very useful for keeping track of people within Camelot, whether it's to find a lost knight or to keep an eye on potential traitors.
One possible plot could be that Harry Potter is somehow transported to the time of King Arthur through a magical mishap. Maybe he has to use his wizarding skills to help King Arthur in a battle against dark magic that is threatening Camelot. His spells and knowledge of magic could be a great asset.
Yes, in some fanfictions, Harry Potter is made out to be a descendant of King Arthur. Writers often create this connection to bring in elements of Arthurian legend into the Harry Potter universe, like the idea of a special destiny or the inheritance of certain magical powers or items related to Arthur.

Yes, in some fanfictions, Harry Potter is made the heir of King Arthur. Writers often create this connection for the sake of a unique and exciting plot.

One way could be through a prophecy. Similar to how there are prophecies in the Harry Potter series, there could be an ancient prophecy that ties Harry Potter to King Arthur. It could be that Harry has a role to play in restoring some of the lost magic or values of King Arthur's time, like chivalry and honor within the wizarding world.
Maybe Prince Arthur is on a quest to find his true identity and he discovers that King Arthur is an important part of his past or future. They meet and King Arthur recognizes a great potential in Prince Arthur. He takes him under his wing and together they face a common enemy, like an evil sorcerer who is threatening Camelot. Along the way, Prince Arthur has to prove himself worthy to King Arthur and the knights of the Round Table.
One possible plot could be that Harry discovers his true heritage as King Arthur's son. This would likely throw the wizarding world into chaos as it challenges the existing ideas about his family. He might inherit some of Arthur's leadership and combat skills, which could be used to fight Voldemort in a new and unexpected way.
In such a crossover, perhaps Harry Potter could use his magic in Camelot. He might help King Arthur fight against dark magic threats that Camelot faces, like Morgana's sorcery. His spells could be a new weapon in Arthur's arsenal.
