You can start by emphasizing its gentle nature. For example, show how it's always the first to comfort other Pokémon when they're scared. Also, highlight its loyalty to Ash. Maybe it refuses to leave Ash's side even in the face of great danger.
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 idea of an unlikely friendship. Percy, being from his own world, and Bulbasaur from the Pokémon world, would make for an interesting friendship dynamic. Another theme might be adventure, as they could go on quests together in different settings.
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.
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.
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.
Since I don't have access to the 'god of the woods novel', I can only make general assumptions. In such a novel, the god of the woods could be an ancient and mysterious figure. Maybe it's a character that has been there since the beginning of the forest's existence. It could have a connection to the spiritual essence of the woods, and perhaps its powers are tied to the natural cycles of the forest, like the changing of the seasons. The god of the woods might also play a role in the lives of the people or creatures living near or within the forest, either as a benevolent protector or a fearsome force to be reckoned with.
