Eevee

Eevee (Japanese: イーブイ Iibui) is a -type Pokémon introduced in Generation I. It's well-known for being the Pokémon with the highest number of evolution possibilities (8), due to its unstable genetic makeup.

Physiology
Eevee is a small, fennec fox-like creature with bushy, brown fur. Its muzzle is very cat-like, with a small, black, triangular nose. It has a fluffy cream-colored ruff around its neck and a short, bushy, fox-like tail with a creamy tip. Eevee has round, deep-brown eyes, long rabbit-like ears, and pink paw pads on its little feet. Its paws are small with three toes and no visible claws.

Eevee, as well as its evolutions, possesses traits from different animals. Eevee shares most traits with the fennec fox. However, it's also based on dogs, cats and rabbits. Eevee is said to have an irregularly-shaped genetic structure, enabling it to evolve into multiple Pokémon.

Gender Differences
Male Eevee have a zigzag pattern at the end of their tail. Female Eevee have a heart-shaped pattern at the end of their tail.

Habitat
Eevee is a Pokémon found mainly in cities. But it is possible that they live anywhere because they evolve to suit their surroundings. Eevee can mostly be found in Kanto but is also found in Johto, Sinnoh, Unova, Central Kalos and Alola.

Natural abilities
Eevee can have either the ability Run Away or Adaptability. Run Away is an ability that will allow the user to run from any wild Pokémon battle, negating the effects of moves that prevent running away like Mean Look and Block. Adaptability increases the users STAB from x1.5 to x2.0. Eevee's Hidden Ability is Anticipation, which lets Eevee sense an opponent's dangerous moves.

Eevee are Pokémon with unstable genetic codes. This gives them the ability to evolve into eight different evolutions triggered by the environment, time of day, friendship levels, or the usage of the evolutionary stones Water Stone, Thunderstone, and Fire Stone.

Evolution
Eevee can evolve into one of eight different forms with different types. These forms include:
 * Jolteon by use of a Thunderstone;
 * Flareon by use of a Fire Stone;
 * Vaporeon by use of a Water Stone;
 * Espeon when leveled up with high friendship during the day;
 * Umbreon when leveled up with high friendship during the night;
 * Leafeon when leveled up in Eterna Forest, Pinwheel Forest, Route 20 in Kalos, Petalburg Woods, Lush Jungle or wherever there is a Mossy Rock;
 * Glaceon when leveled up on Route 217, Twist Mountain, Frost Cavern, Shoal Cave, Mount Lanakila or wherever there is a Icy Rock;
 * Sylveon by knowing a -type move, while leveling up and playing with Eevee through Pokémon-Amie (Gen VI) or Pokémon Refresh (Gen VII) and earning at least two affection hearts.

Anime
Eevee first appeared in The Battling Eevee Brothers. A little boy named Mikey was hiding the Evolution Pokémon from his three older brothers because they wanted him to evolve it. However, when Mikey's Eevee single-handedly defeated Team Rocket, they were able to accept the fact that Mikey wanted to keep his Eevee just the way it is. Ash's longtime rival Gary Oak uses an Eevee of great quality that eventually evolves into Umbreon. May has an Eevee that hatched from an egg, which she used in Pokémon Contests all across the Kanto and Johto region. When May traveled to Sinnoh, she took it to Route 217 to evolve it into a Glaceon. The Kimono Girls who first appeared in the Pokémon Gold and Silver games, also make an appearance with their Pokémon (all of which are evolutions of Eevee) in Trouble's Brewing. The youngest of the Kimono girls had an unevolved Eevee (the only of the sisters to have one), though it evolved into an Espeon later on in the episode Espeon, Not Included. Virgil has an Eevee who acts as a helper to Team Eevee. Serena also owns an Eevee who has a passion and talent for dancing, which later evolved into a Sylveon.

Games

 * Pokémon Yellow: Is the rival's starting Pokémon.
 * Pokémon Conquest: As the starter of the player character's Pokémon.
 * Pokémon Mystery Dungeon: Red/Blue Rescue Team: Must be naive nature and female gender to become this Pokémon as the player character.
 * Pokémon Mystery Dungeon: Explorers of Time/Darkness/Sky: Must be jolly nature and female gender to become this Pokémon as the player character.

Pokémon Adventures
In Pokémon Adventures, Red is in possession of an Eevee which had been experimented on by Team Rocket. As a result, it could transform back and forth from the three evolutions Vaporeon, Jolteon, and Flareon along with its base form, allowing it greater tactical ability in fighting other Pokémon. Eventually, it evolved into an Espeon, losing its special ability to interchange abilities.

Electric Tale of Pikachu
In The Electric Tale of Pikachu manga, the character Mikey (who appeared in the anime episode: "The Battling Eevee Brothers") makes an appearance with his own Eevee and within the chapter that he appears in, Mikey attempts to prove to his brothers that he doesn't need to evolve his Eevee to win battles.

Origin
Eevee has many mammalian traits, mostly traits of the fennec fox, citing their brush tail and lithe body structure. Eevee resembles a domestic puppy, while possessing some rabbit-like traits; namely its long ears and mane. It also shares traits with felines as well, as it has a short muzzle, possessed by all evolutions of Eevee.

Etymology
Eevee's name likely comes from the letters E-V, an abbreviation for the word "evolution". It's Japanese name, Iibui, literally means "evolve". Eevee's original name, Eon, is simply the word eon (a long period of time).
