Vaporeon, Jolteon and Flameon

If Eevee is given a Fire Stone, it will evolve into Flareon, becoming a Fire Pokémon. It has orange fur, covered in a yellowish mane on its chest, as well as a tuft on its forehead and a padded tail of the same color.

This Pokémon can store heat energy throughout its body, keeping its temperature between 700 and 900 degrees Celsius. Inside its body, it has an organ that acts as a fire chamber, shaped like an inner bag that is over 1,700 degrees Celsius, where some of the air it inhales ends up. Because of this, when it exhales, it is usually around 3,000 degrees Celsius. The softness of its neck fur is used to release heat so it doesn't end up suffocating; by hollowing out its fur, it releases all that heat. It can release its heat even while asleep. Before eating, whether it's berries or some prey it has caught, it uses its flames until it is thoroughly cooked. A sign that it is about to attack is when it is seen taking a deep breath before releasing its fierce flames. Whenever its mood changes, the flames in its fire chamber flare up even more fiercely.

They are very curious Pokémon, and everything catches their attention, causing them to become excited and increase their body temperature. They are often seen near cities or in warm places like active volcanoes.

Like the other Eeveelutions, Jolteon is based on a canine. Its fur allows it to capture and store large amounts of static electricity from the environment, causing it to bristle and harden into spikes, which it can use to focus and direct its electric attacks at its opponent. Its cells generate a low level of electricity, which, amplified by the static electricity in its skin, allows it to fire lightning bolts. Its neck is white, the rest of its body is a bright yellow, its eyes are black, and it is the only Eevee Evolution that lacks a visible tail, which blends in with its fur.

This is a very sensitive Pokémon with a nervous nature, meaning it gets sad, scared, or angry very easily. These mood swings give it energy, which can make it difficult to get along with. It can accumulate negative ions from the atmosphere to launch lightning bolts of up to ten thousand volts in power. It can also use its spiky fur to turn into sharp spikes, which it can launch in bunches by shaking its body to pierce and shred its opponent. It has a special organ in its lungs that is capable of generating electricity; this can be verified by listening to it breathe, as an electric crackling can be heard. You have to be careful when its fur is bristling, as it is a sign that it is about to unleash a discharge, and lightning can also strike nearby. Its fur is so full of electricity that even those that fall to the ground take a while to fully discharge.

They live in cities and countryside. Some use them to herd groups of Magnemite because of the electricity they store and generate.

If Eevee is exposed to a Water Stone, it evolves into Vaporeon. Vaporeon's body is mostly blue. It has pointy yellow ears; when they start to vibrate, it indicates that it will start to rain in the next few hours. It has a fin on its head similar to that of a sailfish, and a similarly shaped membrane surrounds its neck. It has a row of membranous spikes on its spine that extend down the length of its back.

Its physical constitution is adapted to subsistence in water, mainly thanks to its tail, which is topped by a mermaid-like fin that helps it swim. Due to the shape of its tail, it is sometimes mistaken for one; others believe it is the origin of mermaid tales. It is not easy to see it when it is swimming, because the bluish hue of its furless skin makes it mistaken for the water. It also has the unique ability to become invisible underwater, due to its molecules being very similar to those of water, allowing it to blend in. Its power in this environment is such that it can control the water. Its hunting method is to blend in with the water, patiently waiting for a fish Pokémon to appear and get close enough to catch it. If it senses danger or an enemy, it will dive underwater to hide. Only when it is asleep on dry land can it be seen up close.

They always live near water, whether in rivers or oceans, as long as the water is clean, fresh, and crystal-clear. In the oceans, they can be seen on the beautiful coasts of these waters; these are their favorite places. They like to hide in holes in the water.
