Eevee made its contest debut in a match against Brock and his Marshtomp in What I Did for Love, where it won.
In A Full Course Tag Battle!, May revealed that her Eevee had evolved into a Glaceon by coming into contact with the Ice Rock near Snowpoint City.
In Strategy With a Smile!, May used Glaceon in the finals of the Wallace Cup where it was up against Dawn's Piplup. Glaceon lost the match by only a few points.
