One idea could be to have the characters from Harry Potter interact with the Guardians from Destiny in a battle against a common dark magic - influenced enemy. For example, Harry Potter could team up with Cayde - 6 to fight off a horde of Death Eaters and Fallen that have somehow merged their powers.
Perhaps the Voldemort threat in the Harry Potter world is somehow connected to a Darkness - like entity in Destiny. Harry and his friends must learn new combat techniques from the Guardians or other Destiny characters to combat this new, more powerful form of the Dark Lord. They could also exchange magical and technological knowledge, which would be really cool to see.
Harry Potter and Cayde - 6 would be an interesting pairing. Harry is used to the world of magic and mystery, while Cayde - 6 is a witty and resourceful Guardian. They could learn a lot from each other. Cayde - 6 could teach Harry some cool combat moves from Destiny, and Harry could introduce Cayde - 6 to the wonders of magic like Apparition.
A believable plot could also involve a magical accident that somehow links the two worlds. For instance, a spell gone wrong by a Hogwarts student could open a portal to the Destiny world. This would then lead to characters from both sides having to work together to close the portal and deal with the consequences of the two worlds colliding. The characters' personalities should remain consistent. So, Luna Lovegood would still be her dreamy, yet perceptive self, and she might be the one to notice some unique similarities between the magic in both worlds.
In Harry Potter fanfiction, 'Forging Destiny' could refer to a story where characters take control of their fates in ways that deviate from the original series. It might involve characters making different choices, perhaps Harry himself being more proactive in shaping the wizarding world's future, instead of just reacting to Voldemort's actions.
Perhaps he witnesses a great evil that he could have prevented if he had been more accepting of his role earlier. This guilt and the knowledge of the consequences of his inaction could drive him to accept his destiny. Or, it could be that his friends are in great danger because of his hesitation, and he decides to embrace his destiny to save them.
Yes. It could be an interesting concept as it might blend the elements of Harry Potter with the idea of a 'guardian destiny'. It could potentially introduce new plotlines and character developments that are different from the original series.
One possible plot could be that Harry discovers he has the powers of a Hunter Destiny within the wizarding world. He might use these newfound abilities to fight against dark wizards in a different way than he does with his normal magic. For example, he could have enhanced tracking skills to find hidden Death Eaters.
Well, I haven't come across a 'Harry Potter is a Hunter Destiny' fanfiction myself. However, if you look for it on dedicated fanfiction communities, you might have better luck. Some of these communities have search functions that allow you to filter by specific tags or concepts. You could also ask around in relevant forums where Harry Potter and fanfiction enthusiasts gather.
In some fanfictions, Harry Potter might be seen as a guardian from destiny because of his pre - ordained role to defeat Voldemort. His very existence was prophecied to be the downfall of the Dark Lord. This prophecy set him on a path where he was constantly in a battle against the forces of evil. He was destined to face challenges and protect the wizarding world, thus becoming a guardian in the context of the fanfiction's narrative.
