In a flashback in Team Eevee and the Pokémon Rescue Squad!
Virgil's Umbreon is one of Virgil's Pokémon and part of collection of the Eeveelutions.
Umbreon is Virgil's very first Pokémon that he trained from an Eevee. He was in his possession before evolving when Virgil was younger during the time they were lost in a dark forest. All hope was lost until he evolved into an Umbreon. Using his ability to glow in the dark, Umbreon helped Virgil navigate through the forest by using his glowing rings. During the present-day, Umbreon used Psychic to help create a key to unlock a locked door. Umbreon has also been continued to be relied on for lighting up dark places. In Lost at the League!, Umbreon helped Virgil to calm down a wild Garbodor and a group of Trubbish. In Strong Strategy Steals the Show!, Umbreon defeated Flora's Gothitelle in the fourth round of the Vertress Conference allowing Virgil to progress to the Top 8. He was also used off-screen in Virgil's Vertress Conference battles against Cameron and Dino in A Unova League Evolution!
