Umbreon's first appearance was as an Eevee in the episode 'The Rivalry Revival', where it was easily able to defeat Ash's Pikachu in a battle. However, it was first shown as an Umbreon in the episode 'Power Play', meaning that it must have evolved at some point in the night time before that episode, as it was shown to be an extremely capable and strong battler. Throughout it's life as an Umbreon, it has been one of Gary's most used and prized pokemon, going with him pretty much everywhere along with his Blastoise and Elevtivire.
