Umbreon made its first appearance alongside its trainer, Will and his Xatu when they attacked Green. Umbreon was affected by Bull's Scary Face but still manages to attack Bull with Faint Attack. Umbreon was then knocked out later by Bull when it used Charm and Take Down.
Umbreon was revealed to be an Eevee when Karen was one of the Masked Man's children. Green and Silver escaped from the base and Karen told Eevee to use Bite to prevent them from escaping but it failed.
