In the original series, Harry and Hermione are generally good - hearted characters. In 'evil Harry and Hermione fanfiction', they go against their normal moral compasses. For example, in the original, they would never use dark magic without good reason, but in these fictions, they might embrace it freely.
The worldviews in the original and in the 'evil Harry and Hermione fanfiction' are very different. In the original, Hogwarts is a place of learning and good. In the fanfiction, Harry and Hermione may see Hogwarts as a place to be subverted, to spread their new, often dark ideas. They may not respect the rules and traditions that are so important in the original series, and instead try to break them to impose their own vision of magic and society.
The original Harry Potter series is centered around themes of love, friendship, and the fight against evil. In 'dark evil Harry Potter fanfiction', these themes are often reversed. Harry might be the one causing harm instead of fighting it.
Fanfiction often explores different perspectives. In the original 'Harry Potter' series, we mainly follow Harry's point of view. But in 'Harry Potter and the Fanfiction', we can get inside the heads of other characters like Draco Malfoy or Severus Snape. Also, fanfiction can change the plot. For example, some fanfictions might have Voldemort winning in the end. Another difference is that fanfiction can explore relationships in more depth, such as Hermione and Ron's relationship from a different angle.
The most obvious difference is Harry's identity. In the original, he is a Potter, which shapes his story in many ways. In this fanfiction, not being a Potter means different relationships and a different standing in the wizarding world.
In the official Potter stories, Harry's actions are mostly guided by love and loyalty. But in 'Cold Hearted Harry Potter Fanfiction', his actions are likely to be driven by a sense of cold logic or self - interest. He may not be as quick to jump to the defense of others or the wizarding world as a whole. Instead, he might be more concerned with his own survival and advancement in a world that he sees as hostile. This creates a very different atmosphere and character arc compared to the original series.
The 'lust potion' in fanfiction often delves into more adult or mature themes compared to the original series which is mainly aimed at a younger audience. Fanfiction writers may use it to explore the more complex aspects of human relationships and emotions that were not explored in the original books. It can also be used to create more edgy and unique storylines that deviate from the more family - friendly nature of the official series.
The 'Beautiful World' might have a more utopian feel compared to the original series. In the original, there are many dark elements like Voldemort and his Death Eaters. But in the fanfiction's 'Beautiful World', there could be less of such threats, focusing more on the positive aspects of magic and the wizarding community.
In the original series, Harry is raised in the Muggle world with some sense of normalcy and kindness from his aunt and uncle (despite their flaws). But in this fanfiction concept, he's under the devil's influence, so he'd lack that basic kindness and normal upbringing. He'd be more inclined towards darkness.
The alternatecodex fanfiction often changes the plot. For example, characters might have different fates. In the original, some characters die, but in the fanfiction, they could survive. Also, relationships can be different. It may show characters who were enemies in the original becoming friends or allies.
In the original 'Harry Potter' series, the focus is on the battle between good and evil in the wizarding world. However, in the 'Harry Potter is of royalty fanfiction', there is an added layer of court intrigue. Harry would be part of a royal family, which means there would be political machinations, power struggles within the family, and diplomatic relations with other magical kingdoms. Also, the settings might be more opulent, like royal palaces instead of just Hogwarts castle.
The main difference is the addition of gods. The original series focuses mainly on the wizarding world, its politics, and Harry's fight against Voldemort. In the fanfiction, there are gods involved which can completely change the power dynamics and storylines.
