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.
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 great example could be a story where Ash's journey begins with Bulbasaur in a unique way. Maybe in this fanfiction, Bulbasaur is the only starter available in the region, so Ash has no choice but to start with it. This could lead to a whole new set of adventures and challenges as Ash and Bulbasaur form a stronger bond earlier on compared to the original series.
Perhaps in this fanfiction, the female Ash has a Bulbasaur that she found in a lemon grove. The lemon grove could be a secret place full of magical energy. The Bulbasaur starts to show strange behaviors because of this place. Ash then has to figure out how to help her Bulbasaur while also dealing with other trainers who are curious about this special Pokémon and the lemon - associated mystery.
They could interact in a way where the female Ash uses lemons to train her Bulbasaur. For example, she could hide lemons around and make Bulbasaur use its sense of smell to find them, which would improve its tracking skills.
One idea could be that Ash's Bulbasaur gets separated from him in a strange, enchanted forest. As it tries to find its way back, it befriends some local Pokémon that are usually shy and elusive. Another plot could be that Bulbasaur discovers a hidden power within itself during a tough battle. Maybe it can suddenly control plants in a much more powerful way than before.
Finding specific 'ash bulbasaur lemon fanfiction' can be a bit tricky. First, you need to ensure that the platform you are using allows such content (not all do due to various rules). Then, look for Pokémon - themed fanfiction sections and search for 'ash bulbasaur' in combination with 'lemon' which might indicate a particular style or plot element, but be aware that the results may be limited.
In the original anime, Ash starts with Pikachu. But in a fanfiction where he starts with Bulbasaur, the initial dynamic with his first Pokémon is different. With Bulbasaur, Ash might have an easier time in grass - type areas as Bulbasaur can blend in and gather information more easily. Also, Bulbasaur's more calm and collected nature compared to Pikachu's stubbornness could lead to different training methods and story progressions.
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.
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.
