Hot Pie. He's just a simple baker boy, but he could have an interesting story. Maybe he uses his baking skills to gain influence in a small town. He could create special pastries for lords and ladies, and in the process, get involved in local politics or even some minor intrigues.
Hot Pie is a character that could be really interesting. He's just a simple baker's boy, but he has his own dreams and fears. You could write about his adventures after leaving Arya, how he tries to make a name for himself with his baking skills in different parts of Westeros. Another one is Podrick Payne. He has shown loyalty and courage, and a fanfic could explore his growth from a young squire to a more confident knight - like figure.
Winky the house - elf. She has a lot of potential. In a fanfic, we could explore her life after being freed from the Crouch family. Maybe she has some unique knowledge about the Dark Arts or the Triwizard Tournament that she's been hiding. Her loyalty and her struggle with her new - found freedom could be really interesting to write about.
Coco Adel could be a really interesting character to focus on in a RWBY Parallel Universe fanfic. Imagine if her love for fashion was not just a hobby but a crucial part of her combat strategy. In the parallel universe, she could design battle outfits that have special abilities. Also, Yatsuhashi Daichi could have a more prominent role. His semblance could be more refined, allowing him to create much larger and more complex barriers that play a vital role in protecting a new, important location in the parallel RWBY world.
Hot Pie is an underrated character. He could be the focus as he travels across Westeros after leaving the Night's Watch. Maybe he discovers a new recipe that has magical properties. Another one is Podrick Payne. He has so much potential. A fanfiction could explore his growth into a great knight, perhaps with some unexpected twists in his training.
I think Neville Longbottom is a bit underrated in this book. A fanfic could focus on his growth during this time. He could have some secret knowledge about the plants in the Hogwarts grounds that helped in some way during the events. Also, Seamus Finnigan could be interesting. What if he had some family connection to the events in the Prisoner of Azkaban? Maybe his family knew something about Sirius Black or the Dementors. And Crookshanks is another character. A fanfic could be about his adventures around Hogwarts, and how he was actually more intelligent than people thought and was trying to solve the mystery of Sirius Black himself.
The Dormouse could be a great character to focus on. In the original stories, it's often overlooked but it could have a much more complex backstory. Maybe it has secret knowledge about the looking - glass world that it's been too sleepy to share. Another is the Tweedle brothers. They could be explored in more depth, perhaps they have a hidden agenda that's not immediately obvious in the main story.
Well, there could be the dragon lords. One might be a powerful fire dragon lord who is fierce and protective of his kind. And on the ice side, a wise ice dragon lord who is known for her strategic thinking.
Rock Lee is often overlooked compared to the main characters. A fanfiction could focus on his journey to become an even greater ninja without relying on ninjutsu. Another underrated character is Shino Aburame. His unique bug - related abilities could be explored more deeply in a fanfiction, like how he might use them in different and unexpected ways.
The neighbor who was briefly shown in the movie could be an interesting character to focus on. We didn't really get to know much about him, but fanfiction could explore his story, like how he managed to survive on his own for so long. Maybe he had some unique skills or knowledge that helped him. Another could be the old man who we saw at the beginning. What was his life like before the invasion? Fanfiction could give him a more detailed backstory.
The old hermit character. He was only in a few scenes but seemed to know a lot. Fanfiction could explore his past and how he came to have his knowledge. There's also the young apprentice who was often overlooked. He might have some hidden powers or a special connection to the treasures that could be delved into.
