Perhaps the main character is a Pokemon researcher. This person is dedicated to understanding the nature of Pokemon and stumbles upon the concept of the 'flame of life'. They then embark on a journey to study it more closely, meeting various Pokemon and trainers along the way. The researcher's Pokemon partners would play important roles in helping them in their quest to unlock the mysteries of the 'flame of life'.
I'm not sure specifically as it's a fanfic. But it could be a young and determined trainer who is on a journey to discover the secrets of the 'flame of life'. Maybe they have a special Pokemon by their side, like a Pikachu with some unique abilities related to the 'flame of life'.
As I haven't had the chance to read 'chasing the flame fanfic', I can't accurately name the main characters. But typically in a fanfic with a title like this, there could be a character who is the driving force behind the 'chasing' action. It could be a young, curious individual with a strong will, or perhaps an older, wiser character who has a special reason for chasing the flame. There might also be supporting characters who either help or hinder the main character's pursuit.
The 'flame of life' in a Pokemon fanfic could refer to a special power or essence. It might be something like a unique type of energy that Pokemon possess, perhaps related to their life force. For example, it could be a power that only a certain legendary Pokemon has, and the fanfic could revolve around a trainer's quest to find or understand this 'flame of life' power.
Since it's a Naruto fanfic, it's possible that Naruto Uzumaki is one of the main characters. He might be the one who first discovers the frozen flame or is drawn into the mystery surrounding it. Other likely candidates could be Kakashi, who could be guiding the younger characters in understanding this new and dangerous element. And perhaps there are some original characters created specifically for this fanfic that also play major roles.
In these fanfics, the main characters can vary widely. One type is the Pokemon trainer - turned - real - life - hero. They are usually kids or teens who already have some knowledge of Pokemon from games or shows and are quick to adapt. They might be joined by their friends or family members. Also, there could be characters who are initially skeptical about Pokemon in real life but then become believers and important parts of the story. For example, a journalist who at first thinks it's all a hoax but then discovers the truth and helps spread the word about Pokemon in the real world.
Typically, the main characters would be the pokemon themselves. For example, the starter pokemon like Bulbasaur, Charmander, and Squirtle are often central to the story as they are the first pokemon that trainers usually get. And of course, Pikachu is a very well - known main character in many pokemon stories.
Obviously, Ash would be one of the main characters. His Pikachu would also play an important role as his trusty sidekick. And then, there could be various legendary Pokemon like Celebi, who might befriend Ash and guide him through different adventures in the Pokemon world.
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.
It could be Pikachu as a main character. Since Pikachu is one of the most popular Pokémon, it would be likely to be involved in the story, perhaps bouncing on the trampoline and having a great time.
Obviously, Cheryl is one of the main characters. She's the center of the fanfic's story. Depending on the plot, her Pokemon would also be important characters. For example, if she has a Pikachu, that Pikachu would play a role in her adventures.
