One reason could be copyright issues. The Pokemon Company might be very strict about how their intellectual property is used in fan - made works. They want to control the narrative and the brand image, so they may ban fanfiction to avoid any unauthorized or unapproved use of their characters, settings, etc.
Pokemon banned fanfiction could be about various reasons for being banned. It might contain inappropriate content like excessive violence that goes against the family - friendly nature of Pokemon. Or it could have elements that violate copyright laws more severely, such as creating new and unlicensed storylines that completely distort the original Pokemon world in a way not allowed by the official creators.
In general, there are no widely - known official Pokemon that are completely banned from all fanfiction. But if we consider unofficial or self - regulated fanfiction communities, they might ban Pokemon that are too popular to the point of over - saturation in stories. This could be something like Pikachu. Since Pikachu is so well - known and used in so many official stories, some fanfiction writers or communities might want to limit its use to encourage more creativity and variety in the types of Pokemon used in their fan - created stories.
A Pokemon fanfiction might be banned if it contains inappropriate content such as excessive violence, sexual content, or offensive language. Since Pokemon is a family - friendly franchise, such content is not acceptable.
The existence of 'pokemon banned fanfiction' can also be due to the vastness of the fan community. With so many people creating their own Pokemon - related stories, there will inevitably be some who make mistakes or intentionally break the rules. Some may want to explore darker or more adult - themed ideas within the Pokemon universe, which is not acceptable given the target audience of Pokemon, mainly kids and young adults. So, these works end up being banned.
It could be due to copyright concerns. Fanfiction often uses the existing Pokemon universe, and if it starts to overstep boundaries in terms of using the brand in ways that the official creators don't approve of, it may get banned. Also, some fanfiction might promote unethical behavior or values that are not in line with what Pokemon as a franchise stands for.
For fans, it means they can't freely create and share their own stories based on Pokemon. It restricts their creative outlet within the Pokemon universe.
It might also be due to the content containing inappropriate or offensive elements. For example, if the fanfiction has elements that are against the family - friendly nature of the Pokemon series, like excessive violence or negative themes not in line with the brand's values, it could lead to a ban.
Some Pokemon might be banned from fanfiction because of their backstories. Take Giratina, for example. It has a rather dark and complex backstory related to another dimension. In some fanfiction communities that aim for a more light - hearted or family - friendly tone, such a Pokemon might not be welcome. Also, from a legal perspective, if a Pokemon has unique characteristics that are very closely tied to a specific part of the official franchise's marketing or storyline, it might be restricted to avoid copyright issues.
The phrase 'pokemon you are banned fanfiction' probably indicates a fan - made story about Pokemon that has been banned. It could be that the fanfiction was too dark or disturbing for the Pokemon universe. The Pokemon brand is generally associated with positive values like friendship, adventure, and teamwork. So, if a fanfiction goes against these values, for instance, by having a main character who is extremely cruel and anti - social, it might get banned. Also, if it spreads false information about the Pokemon lore or misrepresents the characters in a way that the official Pokemon company doesn't approve of, that could lead to a ban as well.
