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 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.
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.
The 'harry potter the other side of hell fanfiction' may center around the idea of redemption or damnation in the context of the Harry Potter world. It could show how certain characters, who might have been on the verge of turning to the dark side in the original story, are fully immersed in a hellish situation in this fanfiction. The story might also introduce a new set of rules for magic that are unique to this hell - like side of the Potterverse. There could be different factions among the characters, some trying to escape this hellish place, while others are trying to gain power within it.
Some fanfictions in the dark side of 'Harry Potter' might focus on the characters' inner demons. For example, a story about Harry being corrupted by the power of the Elder Wand. It could depict his gradual descent into a darker version of himself, struggling with the allure of power and how it changes his relationships with his friends.
I'm not sure specifically as there could be many different interpretations in a Harry Potter fanfic with such a title. It might be about a place that is on the 'right side of hell', perhaps a unique magical location in the Harry Potter universe that has some connection to the concept of hell, like a liminal space where good and evil forces interact in an unexpected way.
Well, in Harry Potter fanfiction, he could be in any kind of world. Maybe a world where wizards rule openly, or one where magic is fading away. It's really up to the creativity of the fanfic writer.
