It evolves from Eevee when leveled up with high friendship during the night.
Umbreon evolved from exposure to the moon's energy pulses. It lurks in darkness and waits for its foes to move. The rings on its body glow when it leaps to attack.
Umbreon has a sleek black body with four slender legs and crimson eyes. There are two pairs of pointed teeth visible when its mouth is open, one in the upper jaw and one in the lower. It has long pointed ears and a bushy tail, each with a yellow band around them. Its forehead and legs have yellow rings on them.
Its yellow markings glow at night and strike fear into anyone nearby. It hides in the darkness while waiting for its opponents, and its yellow rings glow when it leaps to attack. It is also capable of spraying a poisonous sweat whenever it gets agitated.
Behavior and Habitat
This Pokémon is rare in the wild, and is more often found in urban areas under the care of people.
Umbreon shares characteristics with foxes (especially the fennec fox), cats, and dogs — in particular, it may be based off a black cat or black fox. It may also reference the moon rabbit from East Asian mythology. The rings on its body likely represent a solar eclipse.
Umbreon comes from umbra (Latin for shadow or ghost — also the term for the dark portion of an eclipse) and eon (an immeasurably long period of time, presumably in reference to the concept of evolution). Eon is also a suffix shared by all Eeveelutions and was Eevee's prototype English name.
