Maybe the main characters are a group of female warriors. They have their own combat skills and after the battle, they use their skills not only to protect the emperor but also to train his remaining soldiers. They could be from a tribe that has a long - standing alliance with the emperor's kingdom.
The main characters could be a group of peasant girls. They might be kind - hearted and brave. Despite their low social status, they see the emperor in need and step forward to help.
In such a fanfiction, perhaps the girls could use their medical skills to tend to the emperor's wounds. They might bring him fresh water and food to help him regain his strength. Maybe they also use their knowledge of the local area to find a safe place for the emperor to rest and recover.
Obviously, Ash would be one of the main characters. His Pokémon are also likely to play important roles as they are an integral part of his journey. There could also be some new characters that he meets during the Battle Frontier, like trainers who have different training styles that inspire him to change and mature.
Obviously, Harry Potter himself. He would be a central figure as he was the key in the battle against Voldemort. His friends Ron and Hermione would also be important. They've been with him through thick and thin. Neville Longbottom would be another likely main character. His heroics in the final battle would give him a significant role in the post - battle world. Ginny Weasley too, as Harry's girlfriend and a brave witch in her own right.
Arya Stark could be a main character. She could use her skills as a Faceless Man to infiltrate the enemy's camp before a big battle and gather intelligence. Her ability to change her appearance would give her an edge in spying and sabotage operations during the battle.
Well, if it's a crossover with the Transformers universe, Optimus Prime could be a main character dealing with the battle droids. He could try to teach them about honor in combat, which is very different from their programmed aggression.
Obviously, Max and Caroline would be the main characters. They are the core of the '2 broke girls' story, so in any adoption - related fanfiction, they would be the ones taking on the role of adopters. Their personalities, with Max's tough exterior and Caroline's more optimistic and posh side, would create interesting dynamics when it comes to parenting an adopted child.
The main characters could be popular pokemon girls like Misty. Since she's feisty and determined, her being involved in a hypno - related story could be really interesting. Another could be Serena, as she's always evolving in her journey and a hypno situation could be a new twist for her character development.
I'm not sure specifically without reading the story, but it could be soldiers. Since it's about after a battle, soldiers are likely to be main characters as they are directly involved in the battle and would experience the after - effects.
I'm not sure specifically as it depends on the actual story. But it could be the same main characters from 'Girls x Battle 2' like the female warriors or leaders in that game world.
Obviously, Harry Potter himself would still be a central character. He would be dealing with the aftermath of the battle, like post - traumatic stress or trying to bring about positive changes in the wizarding world.
