In the original story, Harry kills Voldemort when he is older. But in fanfiction, with young Harry doing it, it completely changes the character development. Young Harry may not have the same level of experience and wisdom as his older self. So, the way he approaches the battle and the decision - making process would be different. For example, he might be more impulsive in his actions.
The original story has a long - built - up sequence leading to Harry's final confrontation with Voldemort. In fanfiction where young Harry kills Voldemort, this build - up is often skipped or re - written. The power dynamics between Harry and Voldemort are also different. In the original, Voldemort is a very powerful and feared dark wizard. But in fanfiction, young Harry might have some new - found or unexpected power that enables him to defeat Voldemort more easily, which is a departure from the original's more complex power struggle.
Maybe Harry uses some powerful and unexpected spells. For example, he could combine the Patronus Charm with a blasting spell. The Patronus might distract Voldemort while the blasting spell hits him hard.
It's possible that there's a hidden stash of Muggle items in Hogwarts, and Harry stumbles upon it. He discovers the gun there, realizes it could be a powerful weapon against Voldemort, and decides to use it.
Well, in some fanfictions, Harry might use some hidden magic he discovers in Azkaban. Maybe he finds a way to turn the Dementors' power against Voldemort. Since Dementors can suck out a person's soul, Harry could somehow direct them towards Voldemort, weakening him enough to deliver the final blow.
Harry might use his wits and the environment around him while in captivity. For example, if he's held in a place with magical artifacts, he could use them to his advantage. He could break the chains that bind him with a spell - enhanced object and then make his way to Voldemort and defeat him.
The original Harry Potter series promotes forgiveness and the power of love. Harry is shown to be a kind - hearted character who believes in the good in people. But in the 'harry kills the dursleys fanfiction', it goes against this. It shows a more vengeful and darker side of Harry that is not in line with his character in the books. It also changes the family dynamic aspect which is an important part of the original story.
In the original 'Harry Potter' story, good ultimately triumphs over evil. But in evil fanfiction, the opposite might be the case. The values and moral lessons in the original are often twisted in evil fanfiction.
Well, in the original story, Harry is mostly a rule - follower, at least in the big things. But in delinquent fanfiction, he breaks rules left and right. He might not care about getting detention or losing house points like he does in the books.
Well, it's darker. The original series has its serious moments, but the fanfiction takes it to another level. It might have more graphic and intense scenes, whether it's battles or emotional breakdowns. The tone is more somber and gritty.
The main difference is the relationship structure. The original story mostly focuses on monogamous relationships, while the fanfiction explores polygamy. This changes the dynamics of how characters interact with each other on an emotional and social level.
The main difference is the concept borrowed from 'Star Wars' Order 66. In the original Harry Potter story, there is no such pre - planned mass betrayal within the good side like that. In 'Harry Potter Order 66 Fanfiction', it adds a new layer of intrigue and danger as it makes the Order of the Phoenix more vulnerable. Also, it can introduce new plotlines and character developments that are not in the original. For example, characters may have to question their loyalty in a more intense way.
