Well, he might become more cunning and calculating. Maybe he starts to use more devious means to achieve his goals, like Scar from 'The Lion King' who was always plotting. He could also become more self - centered and less concerned about the well - being of others around him.
In a fanfic, the lightning scar could be a portal. Harry discovers that when he concentrates hard enough and uses a special incantation, he can use the scar to travel to different times in the wizarding history related to Voldemort. He uses this ability to learn more about his enemy, but also risks changing the past and the future of the wizarding world.
In some fanfictions, Harry's scar might hurt because of dark magic remnants. Maybe there are leftover spells from Voldemort that still linger and cause pain. It could also be a sign of a new threat emerging, like a hidden follower of Voldemort trying to use dark magic in a new way that affects Harry through his scar.
Well, it might lead to Harry having to isolate himself. If the pain is severe and constant, he may not be able to function normally in his daily life at Hogwarts or in the wizarding world. He could also become a target for those who want to use his pain for their own gain. For example, someone might try to blackmail him or use his vulnerability to get access to secrets he knows. And if the scar hurting is a sign of a new threat, it could put all his friends and the entire wizarding world in danger again.
Yes, there are some hidden sides to the Harry Potter real story. For example, there are a lot of references to real - world mythology and folklore that are not always obvious at first glance. Also, the backstories of some of the minor characters are not fully explored in the main books but can be found in other materials like Pottermore. And the political structure of the wizarding world has its own secrets and power plays that are not always on the surface.
Another plotline might be that the lightning scar becomes a target for a powerful dark wizard who wants to steal its power. This wizard believes that the scar holds the essence of Voldemort's power and if he can extract it, he can become the most powerful wizard. Harry has to protect his scar while also trying to find a way to permanently remove the threat of this power - hungry wizard. He might seek the help of old and new allies, and along the way, discover new things about his own connection to the scar and the magic within it.
Perhaps Harry would try to take over Hogwarts in a more forceful and underhanded way. He might try to oust Dumbledore or other authority figures, using his new - found 'Scar - like' traits. He could also form an unlikely alliance with some of the dark wizards or creatures, thinking that they can help him achieve his power - hungry goals. For example, he might team up with some of the Death Eaters who are still lurking around, which would be a huge shock to the wizarding world.
Well, an effect in Harry Potter fanfiction is that it gives fans a chance to continue the story in their own way. They can imagine what happens after the events of the books. A side effect is that sometimes the magic system in fanfictions can be misused or over - exaggerated. Some fanfictions also have the effect of making characters more complex. For instance, they might give Draco Malfoy more redeeming qualities. But a side effect could be that in trying to be different, some fanfictions lose the essence of what made the original Harry Potter series so great, like the sense of wonder and discovery.
One great fanfiction that explores the dark side in the Harry Potter universe is 'The Darkening of Hogwarts'. It delves into what would happen if dark magic seeped deeper into the school. The characters are faced with moral dilemmas and the story shows how the allure of the dark side can be both tempting and terrifying.
Well, it could be that the dark side has certain powers or artifacts that end up being the key to saving Harry in fanfiction. Maybe a dark wizard has a magical object that, when used in the right way, can reverse a curse on Harry or help him defeat Voldemort. The dark side's resources, which are often feared and shunned in the normal Harry Potter lore, can be turned into something positive for Harry's salvation in fan - made stories.
