Well, perhaps in this fanfiction, the devil gene is awakened when Harry is exposed to a powerful and cursed object. As the gene awakens, he starts to have strange visions and an uncontrollable urge for power. His Hogwarts experience completely changes as he has to deal with this new aspect of himself. He may also attract the attention of dark forces that want to use his newfound power for their own evil purposes.
It could be Voldemort still. Since Harry has awakened the devil gene, Voldemort might see this as an opportunity to either corrupt Harry further or use his new power for his own dark purposes. So he would be the main force against Harry.
The Devil Gene could be integrated as a new form of magic that has been hidden for centuries. A character might discover it accidentally and start to explore its powers, which could lead to new adventures and challenges.
Another concept could be a conflict between those with the Devil Gene and the traditional wizarding society. The Devil Gene might be seen as something dark and dangerous, so there could be a lot of prejudice and attempts to control or eliminate those who possess it. This could create a really tense and interesting story dynamic.
Well, perhaps Harry Potter discovers some ancient magic related to the Jagan in this fanfiction. Maybe he has to face new and powerful enemies as a result of awakening it.
In this fanfiction, it could be that the appearance of the keyblade is a sign of a greater prophecy. Harry, being the chosen one in his own world, is now also the one to awaken the keyblade. He has to face challenges like learning new combat styles, understanding the keyblade's magic which is different from his usual spells. And along the way, he might make new friends or enemies related to the keyblade's origin and purpose.
Well, he could start by trying to find a way back to his own world. But in the process, he gets involved in the affairs of Spira. He might meet some characters who are similar to his friends at Hogwarts. They could form a group and together they explore the mysteries of Spira. Harry could also share his knowledge of magic with the local wizards (if there are any), and in return, learn about the unique magic system of Spira.
No. Harry Potter is its own unique and original wizarding world story created by J.K. Rowling. It has its own distinct plot, characters, and magical system that are completely different from a Devil Slayer fanfiction. The Harry Potter series is centered around the boy wizard Harry's fight against Voldemort in the wizarding world of Hogwarts and beyond, with its own lore and mythology.
Enhanced gene spliced Harry Potter fanfiction often has very creative concepts. The gene splicing can result in characters having unexpected appearances. For example, a character could have scales like a dragon but still be a humanoid wizard. This can make for very interesting visual descriptions in the fanfiction. There may also be new forms of magic that are related to the spliced genes. If a character has genes spliced from a powerful magical plant, they might be able to use plant - based magic in a more powerful and unique way. It can also explore themes of identity. A character with spliced genes might struggle with who they are, whether they belong to the wizarding world or are some new kind of being.
One concept could be splicing the genes of Harry Potter with a magical creature like a phoenix. This might result in him having the ability to self - regenerate like a phoenix. Another could be splicing his genes with a centaur, giving him enhanced speed and archery skills. And perhaps splicing with a mermaid gene, which could allow him to breathe underwater and communicate with sea creatures.
