Umbreon, The Eevee Elite Wiki

Umbreon is Eevee's fifth evolution, and the one most capable of doing damage to enemies. Luckily, it has plenty of ways to support the other Eeveelutions by scouting or using status condition-causing support moves, and its Dark-type powers add a level of protection to allies by preventing opposing Psychics from having their way on the battlefield. Umbreon has traditionally had the most difficult time evolving of all the evolutions- requireing a very happy Eevee at night in an area without clouds
