Obviously, the female version of Harry Potter and Merida would be the main characters. They would be at the center of the story, driving the plot forward with their actions and decisions.
In a 'fem Harry Potter x Brave crossover fanfiction', the two main characters would be fem Harry Potter and Merida. But it could also include some supporting characters from both universes. For example, from the Harry Potter side, Hermione (in a female - only version of the story) could be a source of additional magical knowledge and support for fem Harry Potter. From the Brave side, Merida's mother or brothers could play roles in the story. However, the focus would remain on fem Harry Potter and Merida as they bridge the gap between two very different worlds, with their own personalities, skills, and goals shaping the overall narrative.
It could be about a female version of Harry Potter ending up in the world of Brave. Maybe she teams up with Merida to fight some dark magic that has seeped into both their worlds. They could use their combined magical skills and Merida's archery to take on the threat.
Obviously, Harry Potter and Merida would be the main characters. Harry with his knowledge of the wizarding world and his courage, and Merida with her strong - willed and adventurous spirit. They could team up to face challenges that require both magical and non - magical skills.
In addition to the Hogwarts characters, some of the well - known Pokemon characters could make an appearance. For example, Ash could visit the wizarding world and team up with the fem Harry Potter. He could teach her some of his unique Pokemon training techniques, and they could combine their skills to face challenges. Team Rocket could also be there, causing trouble in the wizarding world and trying to steal powerful Pokemon or magical items.
Obviously, the fem Harry Potter would be one of the main characters. And perhaps she could meet Naruto in an anime world. Naruto's determination and her own magic skills would make them a great duo to face challenges together.
Often, Harry Potter is one of the main characters as it's a crossover. The fem serpent character is also a main character. She could be a new student at Hogwarts who is part - serpent, or she could be a mysterious figure from outside the school who enters Harry's world.
In addition to the main trio from Harry Potter, Dumbledore could also be a major character. His wisdom and powerful magic could be crucial in dealing with Godzilla. He might be the one to come up with a plan to either communicate with Godzilla or find a way to send it back to its own world. On Godzilla's side, there could be some sort of a magical connection or entity that is controlling it or has a link to it, and that could also be considered a main character in the fanfiction.
When the fem Harry Potter encounters Hercules, it would be an interesting meeting. Hercules, being a hero, would respect the fem Harry Potter's own heroic deeds in the wizarding world. They could have a friendly competition of strength and magic. The fem Harry Potter could show Hercules some of her magical combat skills, and Hercules could teach her some physical combat moves. This interaction could lead to a greater understanding between the two different fictional universes.
The female Harry Potter would likely be more independent compared to some of the Twilight characters. She's used to relying on her own magic and wits. The Cullens, who are used to their own vampire hierarchy, might find her disregard for some of their rules refreshing. Jacob could see her as a new kind of ally, someone who has powers beyond what he's used to. Her presence could also make the Twilight characters more aware of the wider world outside of their vampire - werewolf feud.
Definitely Harry Potter himself. He's the hero in the Harry Potter series, so he would be a central figure in the crossover. He could use his skills and courage to lead the way in the new, combined world. Ron and Hermione would also be important, as they are Harry's closest friends and would support him throughout the adventure.
Harry Potter and Simba would likely be main characters. Harry with his magic skills and Simba with his leadership in the Pride Lands could team up for some great adventures.
