I'm not sure specifically which 'Harry Potter betrayed' slash fanfictions exist. But in general, a 'betrayed' theme might involve a character like Harry being betrayed by a close friend, perhaps Ron or Hermione in some dark, alternate storyline created by the fanfic writer. It could explore themes of broken trust and how Harry copes with such a betrayal.
There could be a 'Harry Potter betrayed' slash fanfiction where Harry discovers that Dumbledore has been using him all along for some greater, self - serving purpose. In this kind of fanfic, the writer might show Harry's journey from shock to anger and his attempts to break free from Dumbledore's control. However, it's important to note that most of these are just creative interpretations by fans and not part of the official canon.
Another instance could be Hermione betraying Harry in fanfiction. Suppose she falls in love with someone who is against Harry, like a pure - blood supremacist in a different version of the wizarding world. Her love for this person makes her go against Harry, which is a huge betrayal considering their close friendship in the original story.
I'm not sure of specific examples off the top of my head. But in general, in such fanfiction, it might involve Harry being betrayed by those in his so - called harem, perhaps by lies or broken trust. For instance, a character he trusted might turn out to be working for the dark side and use their relationship to get information on him.
One great example could be those that focus on the budding friendship between Harry and Ron in a really heart - warming way. They might show their adventures at Hogwarts with added cute moments, like sharing a secret joke during a boring Potions class.
One example could be 'The Broken Trust'. In this fanfiction, Fem Harry Potter discovers that her closest friends have been hiding secrets from her that make her feel betrayed. Another might be 'Shadows of Deception' where the magical world turns against her in a cruel way. And 'Forsaken by Allies' shows how Fem Harry is left alone after being betrayed by those she thought she could rely on.
In regular fanfiction, we might see stories that are more in line with the positive aspects of the 'Harry Potter' world, like new adventures at Hogwarts or additional spells and magic. But 'Harry Potter betrayed' slash fanfiction delves into the negative emotions associated with betrayal. It could involve characters acting out of character in order to create a scenario where Harry or other main characters are betrayed. This can be a very different experience for the reader compared to the more traditional fanfics.
One example could be a fanfiction where there are nested storylines about the relationship between Harry and Draco, but with a unique twist on their relationship that goes beyond friendship or rivalry (the slash aspect). Another might be a story that has a main plot about the Hogwarts students, but then within that, there are smaller sub - plots about different character pairings like Hermione and Luna (a slash pairing).
One example could be a story where Harry and Draco form an unlikely friendship that turns into a romantic relationship while also involving other characters like Hermione and Ron in sub - plots that help or hinder their relationship. Another might be a story with a multi - character focus where Sirius and Remus have a relationship and they all deal with the ongoing battle against Voldemort in new and different ways compared to the books.
There could be fanfiction that combines Harry's independent spirit with a slash relationship. He might go against the flow and choose a partner who is not the obvious choice. In these stories, his intelligence helps him see the value in an unconventional relationship. Like a story where Harry, with his sharp mind, realizes that a relationship with an outcast character in the wizarding world can be fulfilling and he uses his independence to pursue it.
One example could be 'The Mentor and the Student'. In this fanfiction, Snape focuses on mentoring Harry in potions without any inappropriate undertones. Another is 'A Different Bond' which explores their relationship in a strictly platonic way, centered around their mutual goal of defeating Voldemort. And 'The Unlikely Alliance' shows them working together for the good of Hogwarts, with no slash elements.
There could be a fanfic where Harry Potter himself is transported to the Star Wars universe and teams up with Luke Skywalker. They combine their skills, Harry with his magic and Luke with his lightsaber and Jedi powers, to defeat a common enemy. Also, a story where the Millennium Falcon crew visits Hogwarts could be an interesting example of this type of fanfiction.
