In certain Pokemon Petrel fanfictions, Pokemon themselves can be main characters. A Pokemon that Petrel has a special bond with, perhaps a Murkrow that he raised from an egg. The story could follow the adventures of Petrel and his Murkrow, showing how they rely on each other in different situations, whether it's in a Team Rocket mission or when they find themselves in a dangerous, uncharted area.
In some fanfictions, Petrel could be the main character in an alternate universe. Instead of being a villain, he could be a Pokemon trainer in a world where there is no Team Rocket. He travels around the region, competing in Pokemon battles and making friends with other trainers. His unique style of training, which was originally developed for more devious purposes in the main storyline, could now be used for positive and sportsmanlike competition.
Obviously, Ash is one of the main characters. Since it's about him being a legendary Pokemon in this fanfiction, he's central to the story.
Obviously, Nyssa is a main character. She is likely to be the central focus of the story, driving the plot forward with her actions and decisions. Another main character could be her first Pokemon, which she has a special bond with. This Pokemon might be her constant companion throughout her adventures.
There might be other trainers in the fanfiction. They could be friends or rivals to Elaine. A rival trainer could constantly challenge Elaine to battles, pushing her to improve. And her friends could join her on adventures and offer support when she faces difficulties.
Obviously, Sawyer is a main character. But there could also be his Pokemon as important characters. Depending on the story, other trainers he meets during his journey might also be main characters. For example, if it's a story about a big tournament, the opponents he faces could be main characters too.
Obviously, Nate is a main character. His Pokemon are also important characters in the fanfiction. Depending on the story, there might be other trainers that Nate meets during his journey, like a rival trainer who constantly challenges him.
Well, obviously Fennel is one of the main characters. She is often the center of the story due to her role as a researcher. Sometimes, the main character from the Pokemon games might also be a main character in the fanfiction, interacting with Fennel and helping her with her research or getting help from her in their own Pokemon journey.
I'm not sure specifically as it depends on the particular fanfiction. It could be a young trainer with a special dragon - type Pokemon like a Charizard or Dragonite.
Another possible main character in the fanfiction could be a Pokemon that has a special connection with Conway. Let's say it's a Pikachu that has some unique abilities. This Pikachu might have been abandoned by its previous trainer and Conway takes it in. Their relationship then becomes a central part of the story, with the Pikachu helping Conway in battles and Conway protecting the Pikachu from danger.
Obviously, Yancy is a main character. She is usually the central focus of the story. Her Pokemon are also important characters. For example, if she has a Pikachu, that Pikachu would play a role in battles and in her emotional journey. Sometimes, there might be a rival trainer who challenges Yancy and becomes a significant character in the fanfiction.
