Perhaps the characters' personalities or the overall tone of the story didn't mesh well with them being butterflies. Maybe the author wanted to keep things more grounded and realistic.
There's a fanfiction where Bill, Charlie and Percy are on a quest related to spiders. It shows how their different skills come into play. Bill's worldly knowledge, Charlie's connection with magical creatures, and Percy's strategic thinking all combine to make for an exciting adventure. They face all sorts of spider - related challenges that keep you on the edge of your seat.
Charlie is also great. His love for magical creatures makes for some really interesting plotlines. He could introduce a whole new world of creatures into the fanfiction that the others have to interact with.
The fact that these characters are from the wizarding world adds an extra layer of fascination to the spiders fanfiction. Spiders in the wizarding world can have all sorts of magical properties. So, seeing how Bill, Charlie and Percy navigate the world of spiders, whether it's dealing with a giant spider or using spider - related magic, is really exciting. It allows for a lot of creativity in the writing and makes the fanfiction stand out.
One interesting fanfiction could be about their adventures together in the Forbidden Forest. Maybe they discover a hidden magical creature that no one has ever seen before. They would have to use their combined skills and knowledge to figure out how to deal with it.
I'm not sure specifically as it depends on the content of the fanfiction. Maybe they find it exciting, or perhaps they have different opinions on it. For example, Bill might be more open - minded and enjoy the creative interpretations, while Charlie could be more critical about any inaccuracies regarding certain elements he's familiar with.
They could be like brothers. Harry has a strong connection with the Weasley family already, and with Bill and Charlie, it could be a natural extension of that. They might look out for each other and support one another in any difficult situation.
They could help Harry by teaching him new spells. Bill might teach him some advanced defensive spells he learned as a curse - breaker. Charlie could show Harry some unique ways to use magic around magical creatures. Hermione would of course be there to ensure Harry studies hard and understands the theory behind the spells.
In a fanfiction scenario, perhaps Hermione has a research project and enlists the help of Bill, Charlie, and Harry. Bill could offer insights from his travels, Charlie might contribute with his expertise on dragons as it relates to the research, and Harry would be there for moral support and to offer his unique perspective as the Boy Who Lived. It could be a story of friendship and cooperation in the magical community.
They could be amused. If the fanfiction has some humorous elements, it might make them laugh.
One great Hermione, Bill, Charlie, Fred, and George fanfiction could be a story where they all team up for a dangerous magical quest. Maybe they have to find a lost artifact that is crucial for the wizarding world. Hermione's intelligence would lead the way in researching about the artifact, while the Weasley brothers - Bill with his worldly experience, Charlie with his dragon knowledge, and Fred and George with their creativity and mischievousness - would contribute in different ways like handling the physical challenges along the way.
