It could be the same Voldemort as in the original series. But his approach to Harry might be different. Since Harry is being raised by Raven, he might be more difficult to target as he has different knowledge and skills. So Voldemort might have to come up with new and more devious plans to get to Harry.
One interesting plot could be that Harry, being raised by Raven, might have a different understanding of magic from the start. He could be exposed to more esoteric and ancient forms of magic that Raven might know. This would give him an edge in his Hogwarts years.
In fanfiction, Raven could be an interesting addition to the Harry Potter and Avengers universes. Maybe she has some sort of magic ability that links her to the wizarding world of Harry Potter and at the same time, she might possess powers that could make her fit into the Avengers' world. For example, she could be a powerful witch who also has enhanced physical abilities like the superheroes in the Avengers. She might interact with Harry Potter characters by using her unique powers to solve some magical problems at Hogwarts. And in the Avengers' side, she could be a new recruit with her own set of skills and backstory.
Yes, there are likely many fanfictions out there that explore such a scenario. Fanfiction writers often come up with unique pairings and storylines. They might create a whole new world where Harry and Raven end up together, with their own set of adventures and challenges in the wizarding world.
Raven could be an ancient and powerful witch who has been living in seclusion for centuries. She might have noticed Harry's special aura or his connection to powerful magic and decided to adopt him to pass on her knowledge.
Raven Roth may also be a character who has a mysterious past related to the dark arts. Maybe she was once involved with a group or a situation that had ties to Voldemort, but she has now turned against the dark side. Her knowledge of the dark arts, though dangerous, could be used to help Harry Potter understand his enemies better and find ways to defeat them. This complex backstory would make her a very interesting character in the fanfiction.
In Harry Potter fanfiction, a raven as a familiar can bring a lot of interesting elements. It might be a symbol of mystery and intelligence, much like how owls are used in the original series for communication. Some fanfictions might give the raven special abilities, like being able to sense dark magic or having a telepathic connection with its wizard owner.
In many Harry Potter fanfictions, the concept of being 'raised by darkness' can take various forms. It might involve a character being brought up in an environment influenced by dark magic or dark wizards. For example, a character could be raised in a family that secretly practices the Dark Arts. This could lead to the character having a different moral compass compared to those raised in the light. They may struggle with the line between right and wrong, as their upbringing has exposed them to unethical magical practices.
Since it's a fanfiction, the possibilities are endless. The 'claw of the raven' could be a symbol or an actual magical object with great power. Harry might be led to the claw by a series of mysterious events. He could meet other magical creatures along the way that either help or hinder him. There could be a prophecy related to the claw that Harry has to fulfill. And the story could also explore the relationships between Harry and his friends in this new adventure, like how Hermione might research about the claw's origin and Ron could be by Harry's side in the physical challenges they face while dealing with the mystery of the raven's claw.
