Bellatrix Lestrange is also really interesting. Her extreme loyalty to Voldemort and her wild, unpredictable nature can add a lot of drama to a fanfiction. You could explore her relationship with her family, especially her sister Narcissa, and how that influenced her actions. Another interesting villain is Draco Malfoy. While he's not a full - blown villain in the end, his struggle between following his family's dark legacy and doing the right thing can be a great focus for a fanfiction.
I think Fenrir Greyback is quite an interesting villain for a fanfiction. He's a werewolf and his brutal nature and lack of remorse make him a terrifying character. You could write about his attacks on humans and wizards alike, and how the wizarding community tries to deal with him. Also, the idea of him having some sort of alliance with Voldemort and the Death Eaters, and what that means for the safety of the wizarding world, could be really exciting to explore.
Well, you could write a fanfiction where the villains from different eras of the Harry Potter world team up. For example, Grindelwald and Voldemort joining forces in an alternate timeline. It would be really interesting to see how their different styles of dark magic would combine and how the heroes would deal with it. You could also focus on a single minor villain like Pius Thicknesse and expand on his character, perhaps giving him a more complex motivation for joining the Death Eaters than what was shown in the books.
Definitely Snape. His complex character with his love for Lily and his role as a double agent has so much potential for exploration through memories. Harry himself is also interesting as his memories can uncover more about his family and his own growth. And Dumbledore, his past is full of mystery and his memories could reveal many secrets about his actions and motives.
Sure. Fanfiction writers often explore unique concepts, and a ring - focused Harry Potter fanfiction could be quite interesting. For example, the ring could be related to one of the Hogwarts houses, perhaps having been created by a founder. It might hold the key to an ancient mystery within the castle walls. Writers could also tie it to the Forbidden Forest, where the ring has some sort of connection to the magical creatures there.
Definitely Ginny Weasley. She has her own growth story, and in fanfiction, it can be elaborated. She goes from being Harry's love interest to a strong, independent witch. Seamus Finnigan could also be a focus. He has a bit of a fiery personality, and fanfiction can show how he matures. And Fred and George Weasley. Their pranks and how they grow into more responsible but still fun - loving wizards can be great to write about.
Kira from The Dark Crystal could also be an interesting focus. If she were in the Harry Potter universe, her natural connection to nature and her strong will could make her a formidable ally. She could teach the Hogwarts students about the importance of nature in magic, which is something that is often overlooked in the wizarding world. Her skills with animals could also come in handy, like when dealing with magical creatures at Hogwarts.
Doctor Strange would be an interesting character to focus on in a Harry Potter MCU fanfiction. He already has knowledge of magic in the MCU, but it's a different kind of magic compared to that in Harry Potter. He could compare and contrast the two magics, and perhaps even learn new spells from the Harry Potter universe. His presence could also bridge the gap between the two universes in terms of magic.
Luna Lovegood is an interesting choice. She has such a unique perspective on the world, and in the post - war era, she could be involved in exploring the more hidden and strange aspects of the wizarding world that were overlooked during the war. Maybe she discovers new magical creatures or lost spells.
Leonidas from '300' would be a great character to focus on. Imagine his reaction to the magic of the Harry Potter world. He's a fearless leader, and seeing him interact with wizards and magical creatures would be fascinating. He might see the magic as a new weapon or a strange form of sorcery that he has to either embrace or fight against.
Neville Longbottom could be really interesting. He's usually so shy and awkward, but at the Yule Ball, he could have a moment of confidence. Maybe he asks a girl who no one expected him to ask, or he could show off some hidden dancing skills. Another option is Luna Lovegood. She might wear a really unique and eccentric dress to the ball, and her strange but endearing personality could make for some great interactions during the event.
I think it would be really interesting to focus on Hermione. She's so intelligent and curious. In Middle - earth, she could study the different magic and lore there. She might be the one to figure out how to combine the magic of the two worlds. For example, she could try to find a way to use the magic of Middle - earth to defeat Voldemort or help the Fellowship in a different way.
