Physiology

Eevee is a small quadruped mammalian fennec fox-like creature with bushy brown fur. Its muzzle is blunt and cat-like, with a small black triangular nose. It has a fluffy cream-colored mane around its neck, and a short bushy fox-like tail with a cream-colored tip. Eevee has round deep brown eyes, long rabbit-like ears, and pink paw pads on its feet. Its paws are small with three toes and no visible claws. In its shiny form, Eevee has white fur instead of brown. Eevee, as well as its evolutions, possesses mammalian traits from different types of animals. Eevee shares traits with most notably the fennec fox. However, it s also based on dogs, cats, and rabbits as well. Eevee is said to have an irregularly shaped genetic structure, enabling it to evolve into multiple Pokémon. Its possible moves are: Tackle, Tail Whip, Helping Hand, Sand Attack, Growl, Quick Attack, Bite, Baton Pass, Take Down, Last Resort, and Trump Card.

Habitat 

Eevee is an urban Pokémon and is found mainly near or even in cities. But it is possible that they live anywhere because they evolve to suit their surroundings. Eevee can be found in Kanto but is also found in Johto, Sinnoh and Unova.

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, or the usage of the evolutionary stones Water Stone, Thunderstone, and Fire Stone.
