Obviously, Harry Potter himself would be a main character. Elrond, who is raising Harry, would also be a central figure. There might also be other elves like Arwen, Elrond's daughter, who could play important roles. Maybe some of Harry's friends from Hogwarts could make appearances in the story, even if it's just in his memories.
The main characters would surely include Harry and Elrond. Harry, as the one being raised in this new environment, and Elrond as his guardian. Additionally, Legolas could be a character in the fanfic. He might befriend Harry or teach him some elven skills. And we can't forget Gandalf. Even though he is a wizard from Middle - earth, his connection to both the wizarding world and Middle - earth could bring him into the story to guide Harry in some way.
Obviously, Harry Potter himself would be a main character. Then, there would probably be some important goblin characters who raise him. For example, a wise old goblin who acts as his mentor, teaching him everything from magic to the ways of the goblin society.
Voldemort would remain a major character. Harry's new abilities and perspective from being raised by Death would make their conflict even more complex. Harry might approach the fight against Voldemort with a different strategy, one that is influenced by the teachings of Death.
Harry for sure. Then there could be his samurai mentors. Maybe there would also be some characters from the original Harry Potter world who interact with him in this new samurai - influenced life. For example, Hermione might visit him in the samurai village and be amazed at the new skills he has learned.
Well, Harry is the central figure in this fanfiction idea. Since he is being raised by Hidan, Hidan becomes a crucial character too. Then, there could be characters like Hermione. She might be either very intrigued or very concerned about Harry's new upbringing. And of course, there could be antagonists from both universes. In the Harry Potter world, Voldemort or his followers could still be a threat, and in Hidan's world, there might be some enemies that could cross over into Harry's life in this fanfiction.
Well, Harry Potter is the central figure, but the Weasley siblings are key too. Fred and George could be like his fun - loving older brothers, teaching him all kinds of mischievous spells and pranks. Ginny would be like a sister, and their relationship could develop in a really interesting way. And Percy, despite his differences from the rest of the family, would also be an important character as Harry would be part of the family dynamic that Percy is also a part of.
Harry, of course, is central. Sirius is likely to be like a father figure to him. Bellatrix Lestrange could be an interesting character in this scenario. Although she's a bit of a dark character, her presence in the Black family and her strong beliefs could create a lot of drama and conflict. Also, Kreacher, the house - elf of the Black family, would be around Harry a lot, and their relationship could develop in unique ways compared to the original story.
Obviously, Severus Snape and baby Harry Potter are the main characters. Severus would be in the role of the caregiver, which is a huge departure from his usual role in the original series.
One interesting plotline could be Harry learning elven magic. Since Elrond is an elf, he would have different knowledge of magic compared to what Harry is used to in the wizarding world. Another could be Harry's interactions with other elven characters. He might form unique friendships or rivalries. Also, his growth in a completely different cultural setting than Hogwarts would be fascinating.
Obviously, Naruto and Erza would be the main characters. Naruto is the young ninja with a lot of potential and a big heart. Erza is the strong and capable character who takes on the role of raising Naruto. There might also be other characters from Naruto's world or Erza's world that make appearances, like Naruto's friends from Konoha in cameo roles, or Erza's guildmates who interact with Naruto as he grows up.
Well, depending on what 'rq' stands for, it could be a group of original characters created for the fanfiction. Maybe there's a wise old wizard who takes Harry under his wing as part of this 'rq' upbringing.
