One common theme is Rotom's exploration. Since Rotom can possess different appliances, many fanfics have it exploring new places or situations by taking over different objects. For example, it might take over a refrigerator in a Pokemon center and have an adventure from there.
No, it is completely inappropriate. Pokemon is a franchise aimed at a wide range of audiences including children. Creating such fanfiction goes against the family - friendly nature of the Pokemon brand and can be considered vulgar and unethical.
There's a fanfic called 'The Secret Life of Rotom'. In this story, Rotom discovers a hidden power within itself. It has a really engaging plot with some unexpected twists. The characters are well - developed, especially Rotom, which is portrayed as more than just a simple Pokemon.
A great way would be to explore Rotom's relationship with a trainer. It could be about how a new trainer is initially scared of Rotom because of its spooky appearance but then learns to appreciate its intelligence and loyalty. They could go on a journey together, facing challenges and growing their bond, which is a positive and family - friendly way to feature Rotom in fanfiction.
In some Pokemon novels, Blue is also considered a top - notch trainer. He is highly competitive and always striving to be the best. His strategic thinking and diverse Pokemon team make him a formidable opponent. He often challenges Red, which pushes both of them to improve and become better trainers.
They add more storylines. The Pokemon series has a lot of potential stories that the official series might not cover. Fanfictions about Ash and a Pokemon girl can explore different relationships, like friendship or romance, that can make the Pokemon world seem more diverse and alive.
Pikachu is a very likely candidate. It's Ash's most iconic Pokemon and has a deep bond with him. Whenever Ash is in trouble, Pikachu often steps up to protect him.
In a 'Pokemon Mastermind of Mirage Pokemon Fanfiction', the concept of mirage pokemon is key. These might be pokemon that are rare, elusive, or even have some sort of special power or quality that normal pokemon don't. The mastermind character would likely be on a journey to discover more about them. Maybe they are trying to protect the mirage pokemon from those who would use them for evil. Or they could be trying to figure out how to use the mirage pokemon's powers to their advantage in a world full of pokemon trainers.
