One idea could be a reader who suddenly finds themselves in the Pokemon world during a big Pokemon tournament. They have to quickly learn about the different Pokemon types and battle strategies to compete. Another plot could involve the reader being a Pokemon trainer from a different dimension where Pokemon have unique abilities not seen in the normal Pokemon world. They then have to adapt and use these new abilities to their advantage while making friends and facing rivals.
A great plot might be that the reader is inserted into the Pokemon world as a Pokemon themselves. They have to figure out how to communicate with other Pokemon and humans while trying to find a way to turn back into a human. Or perhaps the reader is a scientist in the Pokemon world who discovers a new type of Pokemon evolution that could change the whole balance of power in battles. This would lead to many adventures as they try to protect their discovery from those who might misuse it.
One idea could be the reader being a new student at the DWMA. They could struggle to find their weapon partner at first, but then end up with an unexpected and powerful weapon. Another plot could involve the reader having a special ability that draws the attention of the Kishin's minions, leading to various battles and the need for protection from the main Soul Eater characters.
Your self - inserted character could start off as a very weak Pokemon or a non - Pokemon entity. But through hard work, making friends, and exploring the Mystery Dungeons, they gradually grow in strength and wisdom. They could form a special bond with a particular Pokemon team and together they face off against powerful foes and solve the mysteries of the dungeons. Along the way, they learn about the values of friendship, courage, and determination which are important in the Pokemon Mystery Dungeon universe.
One popular plot idea is becoming a Pokemon trainer in the world of Pokemon and having unique adventures. For example, starting with a rare or unusual starter Pokemon. Another is being a part of a special Pokemon research project that uncovers secrets about certain Pokemon species. And sometimes, it's about having a special ability to communicate with Pokemon in a way others can't.
Another plot could be that the human has a special ability that allows them to enter the dreams of pokemon. In these dreams, they learn about the pokemon's past, their hopes, and fears. This knowledge helps the human to better understand pokemon in general and they use this understanding to improve the relationship between humans and pokemon in their world. Maybe they even discover a conspiracy that is affecting the pokemon in their sleep, and they have to stop it.
Well, you could make your self - insert into a Pokemon anime fanfiction as a Pokemon ranger. You'd be tasked with protecting the wild Pokemon and their habitats. Maybe you have a special bond with a Legendary Pokemon that only you can communicate with. Or you could be a coordinator in Pokemon contests, using your unique style to win competitions. It would be fun to describe your journey through the contests, the Pokemon you use, and the rivals you face.
Here are some plot ideas. Your self - inserted self could be a Pokémon trainer who is cursed to have Pokémon attracted to them in an unusual way, forming a harem. They must find a way to break the curse while still maintaining their relationships with the Pokémon. Another idea is that the character is a time - traveler who goes back to the early days of the Pokémon world. There, they meet Pokémon that are not yet fully understood and form a harem. The story could be about how they change the future of the Pokémon world through their relationships with these Pokémon. Also, your character could be a Pokémon whisperer who can communicate with Pokémon on a deeper level. This attracts a harem of Pokémon with special needs or powers, and they work together to help other Pokémon in the world.
A third idea is that the reader is a Pokemon trainer who has lost their memory. They wake up in a Pokemon center with no recollection of who they are or what their Pokemon are. With the help of the Pokemon center nurse and their own Pokemon, like a Pidgey, they start to piece together their past. As they travel around to different places looking for clues, they encounter various challenges and make new friends, both human and Pokemon.
You could insert yourself as a human knight. Picture this: you are part of the Stormwind army, and you get involved in the fight against the orcs. During a battle, you find a mysterious artifact that gives you special abilities. This leads you on a quest to find out more about the artifact's origin and how it can be used to save humanity from various threats like the Scourge or the demons.
Your self - insert could be a transfer student from another kingdom with a completely different fighting style. This would lead to interesting interactions with the main characters as they learn from each other. They might introduce new weapons or combat techniques that the others haven't seen before.
A possible plot is that the self - inserted character has to deal with the Omnitrix malfunctioning. This could lead to unexpected and sometimes comical transformations. They might transform into a really weak alien in the middle of a battle or into an alien that is completely inappropriate for the situation, like a tiny alien when they need to be strong. As they try to fix the Omnitrix, they learn more about its inner workings.
