Gallade was a Pokémon Zoey got as a Kirlia. Kirlia was used in battle with Dawn, when she attempted to learn a new combo move. Though Dawn lost, she had a good idea of how to perform it.
Later, Zoey's Kirlia evolved to a Gallade prior to the final stage of the Grand Festival. Using Gallade and Glameow, Zoey fought against Dawn's Togekiss and Piplup. Though their strategies were very well planned, Zoey's Gallade powered up Glameow, which caused Zoey to win the Festival.
