Pokemon Celebi Transformation Fanfiction: What are some interesting plot ideas?

One idea could be that Mew and Celebi team up to save a dying forest. Since Celebi has a strong connection to nature and Mew is a very powerful and curious Pokemon, they could use their unique abilities to heal the forest. Maybe there's a dark force polluting the forest, and they have to find the source and stop it.

When Celebi initiates the transformation, it's like a wave of emerald light washes over the target. First, there's a tingling sensation all over the body. Then, the physical features begin to shift. If it's a transformation into a flying - type Pokemon, the back might start to bulge as wings start to form, feathers sprouting out in a flurry. The face would change too, the nose becoming a beak perhaps, and the eyes taking on a different shape and color. Every detail of the transformation can be described in a very tactile way, making the reader feel as if they are witnessing it firsthand. You can also add in the sounds, like a soft whooshing as the transformation energy moves around.

One idea could be a young trainer discovers an ancient spellbook that has pokemon transformation spells. He accidentally casts one on himself and turns into a Pikachu. Then he has to figure out how to reverse the spell while experiencing the world from a pokemon's perspective.

One idea could be a Vulpix that gets transformed into a different type of Pokemon due to a magical artifact. It then has to learn to adapt to its new form and abilities while trying to find a way to change back. Another plot could involve a trainer who accidentally causes the transformation of their Vulpix and they go on a journey together to figure out how to reverse it.

In 'pokemon horror transformation fanfiction', the idea of a Pokemon's body mutating in grotesque ways can be really interesting. Maybe a Bulbasaur with its bulb growing out of control, sprouting thorny vines that seem to have a life of their own and lash out at anything nearby.

One idea could be a human accidentally getting bitten by a vampire during a full moon and slowly transforming while struggling to hide it from their family. Another could be a vampire choosing a human to transform as a way to save them from a terminal illness. And a third could be a group of humans being hunted by vampires and one of them getting turned and having to choose between their old life and their new vampire existence.

One popular idea is a trainer being transformed into a Pokémon. This often leads to interesting adventures as they have to adapt to their new form and abilities. For example, they might learn how to use moves like Pikachu's Thunderbolt from a completely different perspective.

One idea could be the main character being reborn as a Pikachu and having to navigate the world with its electric powers while making friends with other pokemon. Another could be being reborn as a Eevee and having the unique ability to evolve into any form at will, which causes both envy and admiration among other pokemon. Maybe the reborn pokemon has memories of being a human and uses that knowledge to outwit trainers and other threats.

Well, perhaps a plot where the character's transformation is tied to their emotions in a very unique way. So, when they're extremely angry, they transform into a powerful and somewhat uncontrollable form, but when they're calm and focused, it's a more refined and strategic transformation. And then there could be a quest in the fanfiction to fully master these different states of transformation.

Another plot could involve Spyro being cursed to transform into a tiny dragon, much smaller than his normal size. He then has to navigate the world in this new form, facing challenges like being hunted by small predators that were once no threat to him. It would be a story of adaptability and finding strength in a different form.
