Glameow was originally found on the streets of Snowpoint City. Zoey treated it at school, along with Candice, though they were not supposed to bring her back to their houses.
After Zoey went on the Pokémon journey and entered the Contests, Glameow is usually the Pokémon she uses in her Contest battles. Her Shadow Claw can trick people, as Zoey can make a brilliant counter attack.
Glameow's most important battle was with Zoey's Gallade against Dawn's Piplup and Togekiss. Though Togekiss and Piplup worked almost as good as she and Gallade, Zoey managed to power Gallade via Glameow's Thunderbolt, as Gallade was using Psych Up. Time went out and while both sides were amazing, Zoey lost less points, earning Glameow, Gallade and her master a victory and a title of Top-Coordinator.
