Eevees

Eevee is a Normal-type Pokémon introduced in the original games. It is a small, quadrupedal mammal with brown fur, a fluffy tail with a darker tip, large ears with dark inner coloring, and a cream-colored muzzle and chest. Eevee is notable for its unstable genetic structure, which enables it to evolve into several distinct forms.

Eevee's evolutions, known as Eeveelutions, comprise eight forms with unique typings: Vaporeon (Water); Jolteon (Electric); Flareon (Fire); Espeon (Psychic); Umbreon (Dark); Leafeon (Grass); Glaceon (Ice); Sylveon (Fairy). In most games, Vaporeon, Jolteon, and Flareon evolve via Water Stone, Thunder Stone, and Fire Stone, respectively. Espeon and Umbreon evolve from Eevee through high friendship, during daytime and nighttime respectively. Leafeon and Glaceon were introduced in Generation IV and originally evolved near Moss Rock and Ice Rock, with later titles offering alternative methods. Sylveon evolves when Eevee knows a Fairy-type move and has a high level of affection when leveling up.

Use in games and media: Eevee's versatility makes it a popular choice for trainers seeking type coverage. It appears in many main-series titles, spin-off games, the anime, and the trading card game, often depicted as a friendly, adaptable companion with a strong bond to its trainer.

Taxonomy and statistics: Eevee is categorized as the Evolution Pokémon. It stands about 0.3 meters tall (1 foot) and weighs about 6.5 kilograms (14.3 pounds). Its National Pokédex number is 133.
