Another way is to consider different backstories. Maybe a character was once a member of an evil team but had a change of heart. Or a trainer who grew up in a family that was against Pokemon training but decided to follow their own path.
Another way is to give them unique abilities related to their colors. A red - yellow character could have the ability to create heat or light, while a blue - green character could have powers related to water or plants. Their physical appearances could also be inspired by their colors, like having red hair for the red - side character or blue eyes for the blue - side character.
Ash Ketchum is also very popular. He is the main character in the Pokemon anime series that is based on the Red, Blue, Green and Yellow games. Fanfics often explore different versions of his journey, like what if he made different choices during his Pokemon battles or when choosing which Pokemon to catch. Also, Misty is quite popular. Her feisty personality and her love for water - type Pokemon make her a great character for fanfic writers to explore different storylines with, such as her own solo adventures or her relationships with other characters.
One idea could be a story where the main character is a Pokemon trainer who discovers a rare and powerful Pokemon that no one has ever seen before. They then have to protect it from evil organizations who want to use it for their own gain.
To create unique pokemon characters in pokemon breeder fanfiction, think about their backstories. A pokemon that was abandoned by its previous trainer might have trust issues and be more independent. Also, consider the environment they come from. A pokemon from a volcanic area might have adapted in ways that other pokemon of the same type haven't. You can also add new moves or abilities to them. If you have a normal - type pokemon, you could give it the ability to turn invisible for a short time. And don't forget about their relationships with other pokemon and humans in the story.
Look at the existing character traits in Blue Exorcist and mix them up. For example, if there are calm and collected characters, create a new character who is calm most of the time but has sudden outbursts of emotion. You can also base characters on different mythologies or cultures that haven't been explored much in the series. Maybe a character inspired by Scandinavian folklore who has unique powers related to ice and snow.
Some fanfics in the Pokemon Red, Blue, Green and Yellow universe might center around a time - travel concept. A trainer could accidentally travel back in time to the early days of Pokemon discovery in the Kanto region. There, they meet the very first Pokemon trainers and learn about the primitive ways of training and capturing Pokemon. This could involve trying to adapt their modern - day training knowledge to the more basic techniques of the past, while also dealing with the potential changes they might accidentally make to the timeline.
You can start by giving them distinct personalities. For example, a trainer who is obsessed with Zygrade's beauty but is also very clumsy in battles. Another way is to give them unique backstories. Maybe a character was once saved by a Zygrade as a child and has been looking for it ever since.
You can start by giving them unique goals. For example, a trainer who is not interested in winning battles but in collecting the rarest Pokemon accessories at the Battle Chateau. Also, consider their appearance. A trainer with bright pink hair and a punk - style outfit would stand out. Another way is to give them an unusual backstory. Maybe a trainer was once a chef and now uses cooking skills to train Pokemon. For example, they make special Pokeblocks that boost their Pokemon's abilities.
Think about the different cultures in Alola. You could create a character who is a descendant of an ancient Alola tribe and has special knowledge about Pokemon passed down through generations. This would make them unique and add an interesting element to the story.
Give them unique appearances. Maybe a trainer has a distinct style of clothing inspired by a certain type of Pokemon. This can also tie into their personality. For instance, a trainer who loves Electric - type Pokemon might have a bright, electrifying color scheme in their clothes. Also, consider their Pokemon teams. A character with a team full of Poison - type Pokemon might be seen as more mysterious or edgy compared to someone with a team of cute Normal - type Pokemon.
