Well, it depends on the specific fanfiction. There are countless Supernatural fanfictions out there, and some authors might decide to incorporate Percy Jackson as a hunter. However, not all fanfictions will do this. Some might keep the two universes completely separate, while others might give Percy a different role altogether in the Supernatural - inspired story.
One popular Percy supernatural fanfiction might be those that involve Percy joining forces with the Winchester brothers in 'Supernatural'. For example, a story where Percy's powers blend with their hunting skills to take on a powerful supernatural entity. Another could be a story where Percy has to deal with Greek monsters in the 'Supernatural' universe, like a Minotaur showing up in a small town that Sam and Dean are investigating.
Archive of Our Own (AO3) is also a great place. It has a very user - friendly interface and a lot of well - tagged fanfictions. You can filter the results based on various criteria such as rating, word count, and completion status. Many talented writers choose to post their Percy Jackson Supernatural fanfictions there.
If Percy Jackson was a hunter in Supernatural fanfiction, it would likely be a very action - packed scenario. His demigod powers would make him a formidable hunter. For instance, his superhuman strength and speed could help him in chasing down and fighting creatures. And his ability to communicate with sea creatures could potentially be adapted to communicate with other supernatural entities in some unique way. He would also bring his own set of moral and ethical values from his original story, which could clash or blend with the values of the Supernatural universe.
One common theme is the idea of power and its control. In Percy Jackson, the demigods have their own powers, in Supernatural the angels and hunters have powers, and Archangels are extremely powerful. Fanfics often explore how these different power sources interact. Another theme is the fight between good and evil. All three have clear concepts of good and bad forces, and fanfictions might bring them together in new battles. For example, the demigods and the Winchesters might join forces against a powerful demon or an ancient evil from Greek mythology.
There are fanfictions where Percy and his friends get dragged into the world of Supernatural. Maybe they end up in a town being haunted by a vengeful spirit, and they have to use their demigod powers along with the knowledge of the Winchesters to figure out how to exorcise it. The contrast between Percy's Greek magic and the more Christian - based exorcisms in Supernatural can make for really interesting reading.
First, you need to know both universes well. Study the characters, settings, and rules of the Percy Jackson series and 'Supernatural'. Then, come up with an interesting concept. For example, you could have Percy and Dean Winchester swap places for a day. Next, create a plot. Maybe start with a problem, like a new type of monster that combines Greek and 'Supernatural' elements. Outline your story, including the beginning, middle, and end.
In a crossover fanfiction, the demon could be a result of some dark magic experiment gone wrong that combines the elements of both universes. For example, a sorcerer in the Percy Jackson world tries to use a spell from the Book of the Damned (from Supernatural) and accidentally creates a super - powerful demon. Percy and his friends, along with the Supernatural hunters, would then have to figure out how to stop it. This would involve the demigods using their unique powers like controlling water or flying, while the hunters use their knowledge of exorcisms and demon lore.
One great story could be 'Demonic Alliances'. It might involve Percy Jackson's world of demigods colliding with the Supernatural universe's hunters when a powerful demon targets both. The demigods' powers and the hunters' skills combine in unexpected ways to fight the demon threat.
One idea could be that the demigods from Percy Jackson's world get caught in a case that the Winchester brothers from Supernatural are investigating. Maybe it involves a monster that has both Greek mythology roots and the dark, supernatural elements from Supernatural. For example, a chimera that is being controlled by a demon to cause chaos in both the mortal and demigod worlds.
