One possible main character could be a spy who has infiltrated an evil team. They are constantly texting their handlers outside the team to pass on information about the evil team's plans. And of course, there could be the top enforcer of an evil team, who is texting threats to those who oppose the team's goals, like trainers who protect certain Pokemon habitats. Their texts could be full of intimidation and show the power they hold within the team.
One interesting plot could be that the evil teams are texting about a secret plan to steal a rare and powerful Pokemon. They might be discussing how to infiltrate a heavily guarded location where the Pokemon is held, like a special research facility. They could be trading information about security measures and the best time to strike.
Ash and his friends would be obvious choices. Ash has a lot of experience in dealing with different Pokemon and has faced evil teams before. His Pikachu could be a key factor in battling against the combined forces. Also, other strong trainers like Misty and Brock could join in, each bringing their own skills and Pokemon to the fight.
Well, chaos would likely ensue. The combined power of the evil teams could mean more powerful Pokemon being used for bad deeds. They might target major cities in the Pokemon world, like Saffron City, causing destruction and panic among the citizens. Trainers would have to band together to fight this new, stronger threat.
Obviously, Evil Pikachu is a main character. There might also be trainers who are trying to either stop it or control it. Maybe some other Pokémon that are allied with or against the Evil Pikachu could also be considered main characters.
Maybe an older priest who has a long - time companion Pokemon, like a Growlithe. He uses his experience with both the church and Pokemon to guide the younger members of the congregation, especially those who are also trainers. He helps them see how their Pokemon can be a part of their faith and not just for battling or collecting.
The main character could be a young trainer named Ash. He's always eager to learn more about Pokemon and is very friendly. Another character could be Misty, a girl who is really good with water - type Pokemon and is a bit of a tomboy. There could also be Brock, who is knowledgeable about Pokemon care and often gives advice to other students.
A young trainer from an underdog region who rises to be a leader in the war effort. He or she could have a unique bond with a Pokemon that gives them an edge in battles.
Another possibility for main characters could be Rainbow Dash from MLP and Blastoise from Pokemon. Rainbow Dash is brave and loves adventures, which would be perfect for exploring the new Pokemon world. Blastoise is strong and reliable. They could form a great team, with Rainbow Dash using her speed to scout ahead and Blastoise using its water attacks to protect them from danger.
It could be an experienced trainer who has a team of fully - evolved Pokemon. This trainer might be taking a break from their usual battles and just wants to relax at the beach with their Pokemon pals. Maybe they have a Charizard that enjoys sunbathing on the warm sand.
The main character could be a young trainer who just transferred to the Pokemon high school. He or she might be shy at first but has a really strong bond with their starter Pokemon, like a Pikachu. This character would grow throughout the story, making new friends and facing various challenges related to Pokemon training and school life.
