One interesting plotline could be the Carrow twins trying to manipulate Harry into joining their dark deeds, but Harry resists and tries to turn them to the good side. Another could be Harry forming an unexpected friendship with one of the twins that causes a rift between the twins themselves.
In some 'harry and the carrow twins fanfiction', there might be a plot where the Carrow twins have a hidden past that is somehow related to Harry's own family history. As they interact, secrets start to unfold. Harry may discover that the twins are not as evil as they seem on the surface, and together they embark on a journey to uncover the truth about their intertwined pasts, which could involve magical artifacts or long - lost spells.
Well, perhaps there's a plotline where the Carrow twins are given the task to spy on Harry by Voldemort. But as they get to know Harry better, they start to question their loyalty to the Dark Lord. This internal struggle within the twins and their relationship with Harry can make for a very engaging story.
To develop the Carrow Twins, you could start by exploring their backstory. Maybe they had a difficult childhood that led them to follow Voldemort. For instance, if they grew up in a family that was always loyal to the Dark Lord, they might have been indoctrinated from a young age.
One idea could be that the Carrow twins have a change of heart. Maybe they start to see the wrong in Voldemort's ways after a series of events. For example, they witness an innocent being brutally punished by Death Eaters and it makes them question their loyalty.
One possible plot could be the Carrow twins causing trouble at Hogwarts while Harry Potter tries to stop them, and a lemon element could be added in the form of a magical potion that has a sour but also strangely alluring effect on the characters. Maybe it makes them act out of character in humorous ways.
The main characters are Harry, who is the central figure from the original series. The Carrow twins are also main characters. In the fanfiction, they might be portrayed in different ways. They could be cruel followers of the Dark Lord as in the original story, or they could be given more depth, like having their own personal goals and feelings that make them more than just one - dimensional villains in relation to Harry.
A prevalent theme is the idea of redemption. Some fanfictions explore if the Carrow Twins could ever turn away from the dark side. There's also the theme of fear, as they are often the source of fear for the Hogwarts students. They are used to show the oppressive regime during Voldemort's time. And of course, there's the theme of their relationship with each other, which can be complex and often drives the plot in many fanfictions.
In some fanfictions, their twin status might change the way the Sorting Hat sorts them. Instead of Harry going to Gryffindor, perhaps they both end up in Hufflepuff because of their shared values that are more in line with that house. This could lead to a completely different story arc where they are known for their loyalty and hard work rather than Harry's typical Gryffindor - like heroics. Also, their family relationships would be different. The Dursleys might have to deal with two magical children instead of one, which could change the way Harry (and Neville) grow up and view the Muggle world.
One interesting plotline could be that they discover their twin relationship early on and try to keep it a secret from everyone at Hogwarts. They might secretly help each other out in classes and with their rivalries against other houses.
A possible plotline is their different magical abilities. Percy might be really good at transfiguration and charms, while Harry has his natural talent for defense against the dark arts. They could compete in a friendly way, but also learn from each other. For instance, Percy could teach Harry some advanced transfiguration spells, and Harry could show Percy some new defense techniques he learned from his experiences.
Perhaps a plotline where they form a special bond while facing a common enemy. They might have to work together to outwit a dark wizard or a tricky magical creature. It could involve using their unique skills and teamwork to overcome challenges.
One interesting plotline could be the twins getting involved in a magical mystery that Harry also stumbles upon. Maybe they discover a hidden spell together and have to figure out how to use it properly.
