Umbreon is a mammalian Pokémon which has a sleek, black body with four slender legs and crimson eyes. It has two pairs of pointed teeth (one pair in each jaw) which are visible when its mouth is open. 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. Umbreon's Evolution is the result of Eevee being exposed to the moonlight, which altered its genetic structure. Umbreon's yellow rings glow when it is excited, such as when it leaps to attack; or when exposed to the moon's aura, which fills it with a mysterious energy. Umbreon hunts at night and, as such, has well-developed eyes that can spot a prey even in darkness. Its black fur helps it blend into the night while waiting for the right moment to pounce. When it does, its rings emit a dim yet ominous glow, and it lunges for the prey's throat before eating it. Whenever angered or agitated, Umbreon sprays poisonous sweat secreted from its pores into the offender's eyes to protect itself. Umbreon primarily specializes in defensive prowess. As mentioned in Pokémon Sleep, Umbreon is known to be difficult to find while it sleeps during the night. The main reason is due to Umbreon being a nocturnal Pokémon. This Pokémon is rare in the wild, instead being more commonly found in urban areas, under the ownership of other Trainers. Evolution Umbreon evolves from . (Source: Bulbapedia)
