One example could be in a fanfic where Harry Potter is forced to use a dark spell to save his friends from an immediate and deadly threat. For instance, using the Imperius Curse on a Death Eater who is about to kill Hermione, but he struggles with the moral implications afterward.
In some fanfiction, Harry Potter might use dark arts when he's in a situation where the regular magic isn't sufficient. Say, when he has to enter a magically protected place that is warded against all forms of light magic. He may use a dark charm to temporarily bypass the wards. However, this often leads to him being shunned by some in the wizarding community in the story.
He could lose the trust of his friends. In the original series, his friends rely on him to be a force for good. If he starts using the Dark Arts, they would be horrified and might distance themselves from him. Also, he could be in danger of being corrupted by the dark power, which could change his personality and make him more like the villains he once fought against.
One example could be Harry using a magical version of a smartphone to communicate with his friends secretly within Hogwarts. The enchanted device might have spells instead of apps.
One example could be a fanfiction where the Ministry of Magic is corrupt and uses dark magic to maintain control. Another might involve political power struggles within Hogwarts that have dark undertones, like a group trying to impose strict and unfair rules on students. And there could be fanfics where the wizarding world is divided into factions with different political ideologies, leading to a lot of conflict and dark events.
One example could be a fanfic where Harry Potter uses martial magic in a duel against a powerful dark wizard. He combines his martial arts skills with magic spells to create a unique fighting style.
One interesting Harry Potter Dark Arts fanfiction is 'The Dark Ascent'. It delves into the idea of a darker path for Harry, where he is tempted by the power of the Dark Arts. Another is 'Shadow over Hogwarts' which shows how the Dark Arts could seep into the school's everyday life in a more insidious way. There's also 'Dark Alliances' which creates new and complex relationships between characters and the Dark Arts.
One example could be a dark familiar in the form of a shadowy wolf that follows Harry Potter. It might have powers related to stealth and be able to sense danger in the wizarding world. Another could be a raven with a mysterious aura, perhaps having the ability to communicate telepathically with Harry.
Some popular 'Dark Mage Harry Potter' fanfictions include 'Dark Harry's Ascent'. In this story, Harry is pushed to the edge after a series of betrayals in the wizarding world and decides to explore the dark arts. He becomes a powerful dark mage, using his skills to get revenge and also to reshape the power dynamics in the wizarding world. Another great one is 'Harry Potter and the Dark Magic Rebirth'. Here, Harry finds a way to combine the dark magic with the light magic in a unique way, creating a new form of magic that no one has ever seen before. It makes him a very different kind of hero, or perhaps anti - hero, in the wizarding world.
One good example could be 'The Unseen Path' where the Self - Insert (SI) character has to navigate the dark underbelly of the wizarding world. The SI in this fic might have to deal with dark magic in ways that the original characters didn't, adding a new layer of intrigue.
One popular example could be those where Harry has enhanced magical abilities far beyond what is seen in the original series. For instance, he might be able to control all elements with ease. Another could be fanfictions where he has a 'dark' side that gives him a more menacing and powerful aura, yet still uses his powers for what he believes is right in his own way. There are also ones where he is godlike in the sense that he can manipulate time and space, like being able to travel through different dimensions to gain knowledge or power.
It's a complex issue. While the use of the Dark Arts by Harry Potter in fanfiction might seem unethical at first glance, it could be used to develop a more in - depth character study. For example, if a writer wants to explore how Harry could be corrupted or what would happen if he were pushed to the brink. But still, in the context of the original series, the Dark Arts are bad, and Harry using them would be a departure from his character's essence. So, in general, it's not really ethical.
