A cool plot could be that the God of Lightning's power is tied to a prophecy in the wizarding world. Harry is the chosen one not just to defeat Voldemort, but also to inherit and master the power of the God of Lightning. As he tries to understand and control this new power, he has to go on a journey to different magical realms. Along the way, he meets other powerful beings who either help or hinder him. His friends from Hogwarts, Hermione and Ron, accompany him and they all learn new spells and magic related to the God of Lightning's power.
One possible interesting plot could be that Harry discovers he has the power of the God of Lightning within him. He might start to show new abilities like shooting bolts of lightning from his wand or his hands. This new power could attract the attention of both his friends and enemies. His friends would be amazed and a bit worried, while his enemies, like Voldemort, would see him as an even greater threat and plot more deviously against him.
One possible interesting plot could be a crossover where the characters from Harry Potter world encounter the Lightning Devil Slayer. Maybe the Devil Slayer's powers are mistaken for dark magic in the wizarding world at first. Then, they realize that they can work together to fight a common enemy, like a new dark force that combines the elements of the dark arts and the devils the slayer usually faces.
Another possibility is a dark wizard who has been secretly studying the power of the God of Lightning for years. This wizard wants the power all for himself and sees Harry as an obstacle. He could be a former Death Eater who has broken away from Voldemort's group to pursue this power on his own. He would use his knowledge of dark magic and his own minions to try and take the power from Harry.
Well, it could be about Naruto discovering a new power related to lightning and becoming the so - called 'god of lightning'. Maybe he has to face a powerful enemy that can only be defeated with this newfound power.
A possible plot could be that the God of Destruction arrives in the Harry Potter world as a result of a powerful, ancient magic spell gone wrong. This being has no understanding of the concepts of good and evil in the wizarding world. Harry, with his unique ability to see the good in people (and now beings), tries to communicate with the God of Destruction. Meanwhile, Voldemort sees this as an opportunity to either destroy the God of Destruction and gain its power or use it to destroy Harry. Harry has to use his wits, the knowledge he has gained from Hogwarts, and the loyalty of his friends to stop Voldemort and deal with the God of Destruction.
One possible plot could be that Harry discovers his true parentage as the son of a god later in his Hogwarts years. This new knowledge could give him enhanced powers that he has to learn to control. He might also face new enemies who are threatened by his new - found status.
Well, perhaps in this fanfiction, Harry Potter discovers he has some sort of divine connection to the dragon god. Maybe he gains the ability to communicate with dragons and uses their powers to fight against Voldemort. He could also be on a quest to understand the nature of this newfound connection and how it relates to the wizarding world.
Well, the plot could start with Harry having strange dreams about being a God of Destruction. As he delves deeper into this mystery, he realizes that there is a hidden part of the wizarding world that is connected to these divine powers. He then has to navigate through political intrigue in the wizarding world as some want to use his power for their own gain, while others want to destroy him. Along the way, he meets new allies and enemies, and has to make difficult choices about how to use his newfound and extremely powerful abilities.
One possible plot could be that Harry, in a moment of extreme despair during his fight against Voldemort, turns to praying to God for strength and guidance. Maybe he has lost all hope in magic for a while and looks for a different kind of power. This newfound spiritual connection might give him an inner peace that helps him face his challenges more bravely.
One possible plot could be that a new dark force emerges in the wizarding world, and it's a being known as the God of Pain. This entity starts to afflict wizards and witches with unbearable pain, and Harry and his friends have to find a way to stop it. Maybe it's related to some ancient magic that was long forgotten.
One plot idea could be that Harry discovers his new 'God of Mischief' status and uses it to outwit Voldemort in unexpected ways. For example, he could create illusions that drive Voldemort's followers crazy or play tricks on Death Eaters during battles.
