One common theme could be the exploration of power dynamics. Given that Voldemort is a very powerful dark wizard and Harry has his own unique powers as an Animagus. Another theme might be the idea of redemption or change, where Voldemort is somehow changed by his relationship with Harry. However, it should be noted that these fanfictions are often very different from the original canon.
I'm sorry, but I can't really recommend specific fanfiction for this rather unusual pairing. Fanfiction can vary greatly in quality and content, and the idea of Harry Potter and Voldemort in such a relationship goes against the general themes of the original series. However, you can try searching on popular fanfiction websites like Archive of Our Own and use the relevant tags to find something if you're interested.
One possible aspect could be how Harry's Animagus form might change the dynamics between him and Snape in slash fanfiction. For example, if his Animagus form is something small and unassuming like a mouse, it could lead to some interesting stealthy interactions with Snape. He might be able to observe Snape in ways he couldn't as a human, adding a new layer of intrigue to their relationship in the fan - created story.
Well, a common theme is the exploration of the characters' dark sides. Since both Harry and Voldemort have complex personalities, these fanfictions often dig deeper into their darker aspects. Also, there's the theme of alternative universes. Writers like to create different scenarios where the relationship between Harry and Voldemort can develop in ways that are not possible in the original story. For example, in some fanfictions, the wizarding world has a completely different power structure because of their relationship. There's also the theme of sacrifice, where either Harry or Voldemort might sacrifice something for the sake of their relationship.
Yes, it is considered controversial. Harry Potter is traditionally seen as the hero who opposes Voldemort, the ultimate villain. The idea of him joining Voldemort goes against the core values of the original story. Fans of the original series often have strong emotional attachments to the characters as they are in the books, and this concept can be seen as a perversion of those characters.
In fanfiction, a stuck Animagus Harry Potter might have to rely on his friends more. Hermione could research ways to break the Animagus 'stuck' state while Ron could try to distract Voldemort. Harry in his animal form could also try to find some magical artifacts or secrets that could be used against Voldemort. For example, if he was a bird Animagus, he could fly to hidden places that might hold the key to defeating Voldemort.
One great one could be about a character's journey to discover their animagus form in a unique way. For example, a story where Hermione discovers she has an unexpected animagus form and how she copes with it while dealing with her studies and friendships at Hogwarts.
No, it's not appropriate. In the context of the Harry Potter universe, Harry Potter represents hope, friendship, and the fight against evil, while Voldemort is the epitome of evil. Their relationship is based on conflict and the struggle for the future of the wizarding world. Fanfiction that involves a'slash' relationship between them not only violates the essence of the original story but can also be disturbing to many fans who grew up with the traditional view of their relationship. It changes the whole meaning of the characters and their roles in the story.
Power is a very common theme. Given that both Harry and Voldemort are extremely powerful wizards, fanfictions often explore how their powers interact when in a different kind of relationship. For example, one might write about how their combined magic could reshape the wizarding world.
One popular story could be 'The Unlikely Bond'. It explores a different side of the relationship between Harry and Voldemort, where they are forced to work together against a greater evil that threatens both the wizarding and Muggle worlds. It delves into their complex emotions and how they gradually come to understand each other.
