Obviously, the Shadow Triad themselves are the main characters. They are a group of mysterious and powerful figures in the Pokemon world. Depending on the plot, other characters like the main Pokemon trainer from the games or anime could also be important. Maybe a Gym Leader who gets involved with the Shadow Triad's activities.
The main characters in a pokemon shadow triad fanfic would be the members of the Shadow Triad. Each of them has their own unique personality and abilities. But you could also introduce new characters that are related to their past. For example, a former trainer who knew them before they became part of the Shadow Triad. Additionally, Pokemon that are associated with the Shadow Triad, like their signature Pokemon, can also be considered as important characters in the fanfic.
One idea could be exploring the backstories of the Shadow Triad members. Maybe they were once ordinary trainers who were forced into their current role. Another idea is to have them encounter a powerful, new Pokemon that challenges their loyalty to their master. Or perhaps a fanfic where they have to team up with the main Pokemon protagonist to face a common enemy.
One great Pokemon Shadow Triad fanfiction is 'The Shadow's Purpose'. It delves deep into the backstories of the Shadow Triad members. The story is well - written, with a good balance of action and character development.
The mystery surrounding the Shadow Triad. In fanfiction, authors can explore their motives and personalities which are not fully explored in the original games. For example, they might be working for an evil master, but there could be more to their story.
Sirius Black is an excellent choice. His rebellious nature and his connection to Harry can bring in some interesting storylines. He could be like a mentor to the triad, especially when it comes to dealing with the darker aspects of the wizarding world. Neville Longbottom can also be included. He has his own growth arc in the original series, and in a triad fanfiction, he could be a source of support and strength, especially when they are all facing challenges in Hogwarts.
The main characters are Hermione, and the Weasley twins, Fred and George. Hermione is known for her intelligence and academic prowess. She is often the voice of reason among the group.
Well, Naruto himself is likely to be one of the main characters. Since it's about his shadow, he would be central to the story.
If it's a crossover, there could be main characters from both the 'The Shadow' world and the other world it crosses over with. For example, if it crosses over with a detective story, there might be a famous detective from that story as a main character along with 'The Shadow'. They could have a conflict or work together depending on the plot.
Since we don't know the exact details of 'the gathering pokemon fanfic', the main characters could be a group of young and enthusiastic Pokémon trainers. They might be on a journey to become the best and this gathering could be a crucial part of their adventure. It could also feature some Pokémon with special personalities as sort of secondary main characters, like a Pikachu that has a unique ability compared to others. Another possibility is that there are some wise old Pokémon trainers who are the main characters, guiding the younger ones during the gathering.
It could be the challenger themselves. They are usually the central focus, with their own personality, goals and dreams. Maybe they have a rival who is also a main character, constantly competing with them.
The Akatsuki members are the main characters. They bring their own unique abilities and goals. For example, Hidan's immortality could play an interesting role in the Pokemon world. He might be more reckless in battles because he knows he can't die easily. Kisame, with his shark - like appearance, could have an affinity for Water - type Pokemon and be really strong in underwater Pokemon battles. These characters' interactions with the Pokemon and each other are what drive the story in an Akatsuki Pokemon Fanfic.
