An old and wise Pokemon professor could also be a main character. He might be the one who first discovers the existence of the worm - like Pokemon or the concept of the crossover. He then guides the young trainer in understanding and caring for this new type of Pokemon, using his vast knowledge of Pokemon biology and history.
A young and curious Pokemon trainer would be a great main character. This trainer could be someone who is always on the lookout for rare and unique Pokemon. When they encounter the worm - like Pokemon, they are immediately intrigued and decide to make it a part of their team.
The worm - like Pokemon itself could be a main character. It could have its own thoughts and feelings, and be on a journey to discover its place in the Pokemon world. Maybe it was born different from other Pokemon and has to face challenges because of its appearance and abilities.
Skitter from 'Worm' could be a main character. She has the ability to control bugs and her strategic mind would make her a force to be reckoned with in Westeros. Maybe she could start as a low - born character and rise through the ranks using her powers and wits, much like some of the more interesting characters in Game of Thrones.
In this crossover fanfiction, the main characters might include a mutated pathogen from 'Plague Inc' that has gained sentience and a worm - hero from the 'worm' world. The pathogen is intent on spreading chaos and destruction in both worlds, while the worm - hero is determined to stop it. Their battles and interactions would drive the story forward as they both use their unique abilities and characteristics to either achieve their goals or thwart the other.
One possible plot could be a trainer in the Pokemon world discovers a strange worm - like Pokemon that has abilities never seen before. This Pokemon could be a key to unlocking a hidden power within the region that an evil team is also after. The trainer has to protect the worm - like Pokemon and use its unique powers to defeat the bad guys.
Naruto is a must - have as the main character. For the Pokemon world, maybe Eevee could be a key character. As for the harem, there could be new female characters created specifically for this fanfiction. They could be a mix of half - Pokemon, half - human hybrids. Also, Hinata could be part of the harem. In the Pokemon world, her shy but strong - willed nature would be an interesting addition, and she would support Naruto in his adventures.
Kirito from Sword Art Online would be an obvious choice. His skills and experience in the virtual world would make him a key character in dealing with the challenges of the Pokemon world. And of course, Pikachu could be a main Pokemon character that teams up with Kirito. Pikachu's electric powers would be useful in battles against other Pokemon or threats in the SAO - like world.
Kirito from SAO could also be a main character in the crossover. He might discover a strange Pokemon in the SAO world and start to learn about its powers. He could then team up with other Pokemon trainers within the SAO world to fight against a new threat that combines the dangers of both worlds.
Maybe a biologist gone bad. He has been studying the worm and discovers that its cells can be used to create a powerful mutagen that can turn ordinary people into super - strong minions. He plans to create an army and take over the city. Spiderman has to stop him from using the worm in this way. And the worm, being an innocent creature, becomes a key piece in this battle between good and evil.
Obviously Percy would be one of the main characters. He could lead the way in exploring the crossover world. His Pokemon partner might be a strong and loyal one. Annabeth could also be a main character, using her intelligence to strategize in Pokemon battles. Grover might tag along, befriending some unique Pokemon. And maybe some of the Pokemon themselves could be considered main characters, like Pikachu if it made an appearance in this crossover world.
Obviously, the pokemon ranger themselves would be a central character. But also, characters like Ash from the main pokemon series could make an appearance. He's a well - known pokemon trainer and his skills and knowledge could complement the ranger's abilities. Another character could be Cynthia, a strong and intelligent pokemon trainer. Her expertise in pokemon could be useful in a crossover situation. And then there's Team Rocket, who could be the villains causing trouble for the ranger and the other characters.
Perhaps an organization made up of both Pokemon world villains and some of Danny's foes. They could be working together to create a portal that would merge the two worlds in a way that benefits them. They would be the main antagonists as they cause all kinds of chaos, stealing both Pokemon and technology from both worlds to achieve their goals.
