is the evolved form of Gladion's Eevee
. It seems to stay outside of its Poké Ball a lot and walks beside Gladion
on their travels.
When Rocket Gang stole Gladion's Lycanroc (Midnight Form)
, it managed to burst it's tire with its Dark Pulse to stop them from getting away.
The eighth match of the Top 16 round of the Alola League featured Gladion's Umbreon
verses Lillie's Vulpix (Snowy)
. The match started with Vulpix using Hail but Gladion wanted to attack quickly so that Vuplix couldn't strengthen its defense. Lillie
figured that the only one possible way they were going to win the match is by using a Z-Move and they directly hit Umbreon Subzero Slammer but it withstood the attack and fought back with an Iron Tail and knocked out Lillie's Vulpix (Snowy)
