One possible plot could be that Bulbasaur discovers a lemon tree in a hidden part of the Pokemon world. The lemons have some special powers that affect the Pokemon's growth. Bulbasaur starts to experiment with the lemons, maybe using them to create new types of moves or to heal other Pokemon faster.
In the fanfiction, there could be a lemon grove that is in trouble. Some dark - type Pokemon are causing problems there. Bulbasaur, being a heroic Pokemon, decides to help. It uses its plant powers in combination with the lemons in the grove. For example, it might use the lemon juice to make a slippery surface to trip up the bad Pokemon or use the lemon peels to create a shield against their attacks.
In the magical world of Build - a - Bear, a new concept was born - a Bulbasaur bear. This bear was not like the others. It was made with a special kind of stuffing that made it bounce around in a really funny way. One day, it escaped from the Build - a - Bear store and ended up in a park. The kids there were amazed. It started doing little jumps and spins, just like how Bulbasaur might play in the grass. The kids chased it around, laughing all the time, and it became the star of a very funny adventure.
Well, one day a Build - a - Bear, which was a teddy bear with a big red bow, met a Bulbasaur in a forest. The Build - a - Bear was a bit scared at first. But the Bulbasaur just blinked its big eyes and made a cute little sound. Then the Build - a - Bear started to imitate Bulbasaur's movements. They both hopped around in circles, which was really funny to watch.
Definitely not. Fanfiction should stay within the bounds of what is acceptable for the general audience of the source material. Pokemon has a large following of young fans, and creating such inappropriate content can have a negative impact on the brand and the fan community. It also shows a lack of respect for the original concept of the Pokemon world which is centered around non - sexual elements like battling, collecting, and evolving.
One common theme could be the bond between Ash and Bulbasaur. Since in the Pokémon world, they have a trainer - Pokémon relationship, in fanfiction, it might be explored in more depth, especially with the 'lemon' aspect possibly adding a layer of emotional or even romantic undertones.
Well, it could be that the character discovers a hidden power or is exposed to a rare energy that triggers the transformation. Or perhaps it's a result of a curse or a wish gone wrong.
You could write about their adventures together. For example, how they team up to face a powerful wild Pokemon or how they help each other during a difficult journey through a new region. This focuses on the spirit of the Pokemon world which is about friendship and cooperation.
A great alternative would be to focus on the relationship between the female Bulbasaur and its trainer. Maybe they enter a Pokémon contest together and have to overcome various difficulties in the competition, showing their bond and teamwork.
