The relationship between them in fanfiction also affects their portrayals. If the fanfiction focuses on a timeline where Dumbledore and Voldemort were once friends or colleagues, their characters will be different from a story where they were always bitter enemies. Dumbledore might show more regret or a sense of failure if he couldn't prevent Voldemort from turning evil in such a scenario, and Voldemort might have a different level of respect or hatred for Dumbledore depending on their past interactions.
In some fanfiction, inquistors are shown as more corrupt than in the original books. They might take bribes or abuse their power for personal gain. For instance, an inquistor could let a known dark wizard go free in exchange for a valuable magical artifact.
In fanfiction, Dumbledore could have set up a series of trials or quests for Harry before the final battle. These experiences make Harry stronger both magically and mentally. Dumbledore might also have a secret plan that he has been preparing for years. He could be using his own powerful magic in a covert way to weaken Voldemort over time, like gradually breaking down the protection spells around Voldemort's Horcruxes so that Harry can find and destroy them more easily.
She is often portrayed as a tragic figure. Writers usually emphasize her delicate state, both physically and mentally. Her magic is also a key aspect in many portrayals, with it being either a source of her pain or a hidden power waiting to be unleashed.
Often, Dumbledore as Death would be a very complex character. He may not be the straightforward evil or good. His role might be more about maintaining a balance in the wizarding world, which is similar to the concept of Death in some mythologies. He could be using his influence on the different characters in different ways. For instance, his relationship with Snape could be a part of his plan as Death. Snape's actions, which were so crucial in the original story, might be reimagined as being directly or indirectly guided by Dumbledore - as - Death. This could add a whole new layer of mystery and intrigue to the fanfiction.
In some fanfictions, Harry's newly - discovered metamorphmagus abilities are portrayed as more raw and uncontrolled compared to Tonks'. For example, in 'The Uncontrolled Shift', Harry has a hard time adjusting and often shifts involuntarily, while Tonks has had years to master hers.
In some fanfictions, Avada Kedavra is used as a way to explore the darker side of characters. For example, a character who was previously seen as good might be forced to use it in self - defense, which then causes them to struggle with guilt. It can also be used to create alternate universes where the spell has different effects or consequences.
They could be portrayed as having a bit of good in them. For example, they might be under some sort of dark spell that forces them to act as they do, and if that spell is broken, they could be more like guardians of the wizarding world in a different way.
In fanfiction, dark creatures can be more sympathetic. For instance, a vampire might be shown as a victim of his own condition rather than just a menacing figure. This gives readers a new perspective on these usually feared beings.
Some fanfictions might explore a more nuanced past relationship between them. Maybe they had interactions in their younger days that shaped their future enmity. Dumbledore, with his deep understanding of magic and people, could have recognized the darkness growing in Voldemort early on and tried to guide him away from it, but Voldemort's pride and thirst for power made him reject any such guidance.
The Death Eaters would also have different character development. They might initially be suspicious of Harry, but as he proves his loyalty to Voldemort, they could start to accept him. Some might even see him as a potential leader in the future. Harry's development might also include changes in his magical abilities. Since he's learning from Voldemort, he could gain new and dark forms of magic. This would change his perception of himself and how others see him. His appearance might even change, becoming more gaunt or having a darker aura, which is a physical manifestation of his internal change.
