A simple plot could be that Eevee and Vulpix are both competing for the attention of a young trainer. The trainer has only one Pokéball left and can't decide which one to catch. Eevee tries to show off its cute and cuddly side, while Vulpix uses its fiery charm. Eventually, the trainer decides to catch neither of them for now, but instead helps them both to grow stronger. Eevee and Vulpix then start to train together under the trainer's guidance, learning new moves and strategies. Along the way, they develop a strong bond and become like siblings in the Pokémon world.
Maybe in the fanfiction, Eevee and Vulpix are both lost in a mysterious forest. They start to look for a way out together. Along the way, they come across ancient Pokémon ruins. Inside the ruins, there are puzzles and traps. Eevee, being a very adaptable Pokémon, uses its different forms' abilities (even if it doesn't actually change forms yet in the story) to solve some of the puzzles. Vulpix uses its fire to light the way and keep away any dangerous Pokémon that might lurk in the dark corners of the ruins. As they progress, they become closer friends and finally find their way out of the forest.
One possible fanfiction could be about Eevee and Vulpix teaming up on an adventure. They might start in a forest where they encounter a group of Pidgey that are causing trouble for the other small Pokémon. Eevee, with its adaptable nature, could use different moves to try and scare the Pidgey away, while Vulpix uses its fire - based attacks to create a barrier. As they work together, they start to understand each other's strengths and weaknesses better, forging a strong friendship along the way.
One common theme is friendship. Since Vulpix and Eevee are both cute and popular Pokemon, many fanfictions focus on their bond. They often go on adventures together, relying on each other.
The plot might involve the male Eevee being a bit of a wanderer and the female Vulpix being a protector of her den. Eevee stumbles upon Vulpix's territory. At first, Vulpix is defensive, but Eevee's friendly nature wins her over. The kiss is a culmination of their growing feelings. After that, they might team up to find a special artifact in the forest that is said to bring great fortune, all while dealing with other Pokémon who are also after the artifact.
Friendship is a very common theme. Eevee and Vulpix are often depicted as having a strong bond, like in many fanfics where they support each other through difficult times. Another theme is adventure. They go on all sorts of quests together in different regions.
In this fanfiction, the plot could involve the Vulpix - the newly - turned - into - Vulpix person, that is - trying to join a group of Pokemon. They face challenges because they are not a typical Pokemon. They don't have the natural instincts at first. But as they go through various adventures, they gradually develop these instincts and become an important part of the Pokemon group. This could include things like helping to protect their territory from other aggressive Pokemon or finding food sources during tough times.
A really interesting fanfiction is the one where Vulpix and Eevee get lost in a strange part of the Pokemon world. They encounter new Pokemon species they've never seen before. As they try to find their way back home, they learn more about each other and their own capabilities. It's full of adventure and discovery.
Well, I've heard of a fanfic named 'Eevee's Encounter with Vulpix'. In this story, Eevee gets lost in a forest and is found by Vulpix. They then start an adventure to find Eevee's way back home. There's also a fanfic where they team up to help a group of baby pokemon that are in danger. It shows their courage and kindness.
One popular theme is the journey they go on together. Maybe they're on a quest to find a special place or item, and their love grows during the adventure.
If they could mate, we might expect a new Pokémon with a unique combination of traits. Maybe it would have Eevee's adaptable potential and Vulpix's fox - like features. However, this is all just speculation as it goes against the current Pokémon breeding rules.
One possible plot could be that Naruto discovers Vulpix lost in the woods near Konoha. He decides to take care of it and Vulpix becomes his loyal sidekick, using its fire - based attacks to help Naruto in battles.
