Umbreon (Japanese: ブラッキー Blacky) is a Dark-type Pokémon. It evolves from Eevee when leveled up with high friendship during the night or when around a Moon Shard. It is one of Eevee's final forms, the others being Vaporeon, Jolteon, Flareon, Espeon, Leafeon, and Glaceon.
It is the Starter Pokémon in Pokémon Colosseum alongside the other Generation II Eeveelution, Espeon.
Umbreon has a sleek black body with a pair of crimson cat or fox-like eyes and yellow bands on its long, pointed ears and bushy, foxlike tail. Umbreon's forehead and legs have yellow rings on them. Its rings are said to glow at night, striking fear into anyone nearby. In Pokémon Stadium 2, Pokémon Colosseum, Pokémon XD: Gale of Darkness, and Pokémon Battle Revolution, these rings glow and slowly pulsate.
