Some authors write 'Harry Turns Dark' fanfics because it allows for a different exploration of the character. Harry is usually seen as the hero, so turning him dark is a fresh take. It can also show how circumstances can change a person. For example, if he was constantly mistreated by the wizarding world.
One popular 'Harry Turns Dark' fanfic could be 'The Darkened Heir'. In this type of fanfic, often the author explores how Harry's experiences could have pushed him towards the dark side. Maybe the betrayal he faced from some in the wizarding world made him bitter. Another could be 'Dark Harry's Ascent' where the story might show how Harry uses dark magic to get revenge on his enemies. And there's also 'Harry: The Dark Lord Reborn' which could play with the idea of Harry taking on a more sinister role similar to Voldemort but with his own motives.
Authors might write 'Harry turns into a girl' fanfictions for a variety of reasons. One reason could be to subvert the traditional gender roles in the Harry Potter story. Harry is a well - known male character, and by turning him into a girl, they can break the norms and create new storylines. Another reason could be to explore how the relationships in the story, such as with Ron, Hermione, and other characters, would be different if Harry was female. It gives a fresh perspective on the familiar relationships. Additionally, it can be a way to attract a wider audience, especially those interested in gender - bending or alternate universe stories.

Authors write 'Harry Potter Silent Treatment' fanfics to explore different relationship dynamics. For example, when a character gives another the silent treatment, it can show underlying tensions or unspoken feelings. It's a way to add drama and depth to the relationships we already know from the books.

There could be a fanfic where Harry is tricked into believing that Voldemort is the only one who can save the wizarding world from a greater threat. For example, a new, more powerful dark force emerges and Voldemort convinces Harry that they need to join forces. In this type of fanfic, Harry would gradually turn towards Voldemort's side as he is deceived by false promises.
Obviously, Harry himself is the central character. Hermione and Ron are also often present. In some stories, they try to save Harry from the darkness, while in others, they become his enemies as he turns dark. Dumbledore may also play a significant role, either trying to guide Harry back to the light or being unable to stop his descent into darkness.

One way it could be plausible is through the use of dark magic manipulation. Voldemort is a master of dark magic. He could perhaps use some form of mind - altering spell on Harry. If he managed to get Harry in a vulnerable state, like when he was feeling isolated or betrayed, the dark magic could seep in and start to change his nature. For example, if Voldemort made Harry believe that his friends at Hogwarts had turned against him, Harry's sense of justice and goodness might be warped, leading him to the dark side.
