This Glaceon is one of Virgil's seven evolved Eevee that is commonly shown with Virgil on his rescue mission and in the third round of the Pokémon League against Russet and his Reuniclus.
Glaceon made a brief appearance with the other members of Team Eevee. He used his icy abilities to create a key to unlock a locked door. Similar to the other Pokémon on the team, he was mentioned to have originated as an Eevee.
In Lost at the League!, Glaceon defeated a Reuniclus in the third round of the Vertress Conference, allowing Virgil to progress to the Top 16. He was also used off-screen in Virgil's quarter-finals battle against Russet in A Unova League Evolution!.
