In a Splatoon Pokemon fanfiction, you could have a plot where a legendary Pokemon has the power to merge the two worlds. This causes chaos at first as the rules of both worlds collide. But then, a group of trainers and Splatoon characters team up. They learn from each other's skills. For instance, the Splatoon characters teach the trainers about ink - based strategies, and the trainers show the Splatoon characters how to train and bond with Pokemon. As they work together, they try to find a way to separate the worlds again if needed or create a new harmonious combined world.
One idea could be a story where Pokemon are able to use the ink - based abilities from Splatoon. For example, Pikachu could shoot out electric - charged ink to battle opponents. Another idea is a crossover world where trainers have to compete in both Pokemon battles and Splatoon - like ink battles. Maybe a Pokemon like Squirtle could be really good at the ink battles because of its natural water - shooting abilities.
A cool fanfiction could involve a group of Pokemon being transported to the Splatoon universe. They would have to adapt to the new rules and the ink - based environment. Some Pokemon might find it easy, like Octillery which could blend in well with the ink - based world. And then there could be a big adventure where they try to find a way back to their own universe while also dealing with the local Splatoon characters and challenges.
A crossover with Pokémon could also work well. The inklings and octolings could enter the Pokémon world and start trading Pokémon while also using their ink skills in Pokémon battles. For example, they could use their ink to create obstacles or distractions during a Pokémon battle, adding a new and interesting dynamic to the battles.
One idea could be a human getting transported into the Splatoon world and having to learn the ways of inklings and octolings to survive. They could start by learning how to use the unique weapons in Splatoon and participate in turf wars.
One idea could be that Naruto characters are transported into the Splatoon world. They might initially be confused by the ink-based battles and the unique species. For example, Naruto could mistake an Inkling for a strange ninja from another land and challenge them to a friendly spar, only to find out about the ink shooting mechanism. Another plot could involve the Akatsuki from Naruto trying to steal the valuable ink resources in the Splatoon world for their own purposes. They would face off against the Splatoon heroes who are determined to protect their world's resources.
One idea could be that the Hypnoshades have a hidden power that only a select few inklings can unlock. And this discovery leads to a race among different teams to find out more about it.
There are fanfictions that focus on the backstories of the existing characters in Splatoon 2. For example, a story about how Agent 3 became such a skilled fighter. It could involve their early training days, the challenges they faced, and how they overcame them to become one of the top agents in the game.
One idea could be a hybrid of Pikachu and Eevee. This hybrid could have the cute appearance of both, with Pikachu's lightning - based powers combined with Eevee's ability to evolve into different forms. It could be a central character in a story where it's trying to find its place in the Pokemon world, being different from the normal Pokemon.
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.
One idea could be to create an OC that has a unique typing combination not commonly seen, like a Ghost/Grass type. This could lead to interesting storylines in the fanfiction, such as how they interact with other Pokemon and trainers. Another idea is to give the OC a special ability that sets them apart. For example, an ability that allows it to communicate with wild Pokemon more effectively, which could be useful in various fanfiction scenarios.
For a Pokemon x Pokemon hybrid fanfiction, you could consider a Bulbasaur and Vulpix hybrid. It would have the plant - based abilities of Bulbasaur like photosynthesis and the fire - based powers of Vulpix. It could use the fire to protect its plants or use the plants to create a unique defense against other fire - types. Also, a hybrid of Jigglypuff and Meowth could be really fun. It might have Jigglypuff's singing ability to put others to sleep and Meowth's thieving skills, which could lead to some really comical and interesting plotlines.
One idea could be a story where the inklings and octolings have to put aside their differences during a world war - like situation. They could form an alliance to fight against a common enemy that threatens both of their species. Maybe this enemy is a new type of sea creature that has been mutated by some sort of toxic waste and has a powerful army.
