Espeon has lilac fur, large ears with dark purple or blue ear insides and long tufts of fur below them, a red gem on its forehead and a pair of pupiless eyes with white irises and purple scleras. Espeon has four slim legs and tiny paws. Its slender tail, which is forked into two at the end, helps it to foresee possible futures. Its catlike appearance and sparkling red gem have caused some to mistake it for a relative of Persian. However, this gem merely augments its psychic powers.
Espeon has developed psychic powers due to a combination of great loyalty to its Trainer and sunlight, with several signature special abilities attributable to its fine, sensitive fur. This very fine fur, which has the look and feel of velvet, is so sensitive, that as air currents pass through it, Espeon is able to sense things such as minute shifts in the air, and predict changes in the weather or the opponent's next move. Like most fully evolved Pokémon, Espeon can learn Hyper Beam or Giga Impact. Connecting with its affinity to sunlight, it is able to learn the healing move Morning Sun.
Espeon are very loyal to their Trainers and will protect them from harm. They enjoy basking in full sunlight. The tip of its forked tail quivers when it is predicting its opponent's next move.
Espeon are usually found in areas that receive a lot of light, or, more commonly under the care of people.
