Kirlia and Leafeon were used in battle with Dawn, when she attempted to learn a new combo move. Dawn's Cyndaquil stood in the middle of Mamoswine's Ice Shard, but the flames melted the ice away. Dawn attempted the combo a second time and succeeded, as Cyndaquil stood firmly in place. As Cyndaquil charged, Leafeon and Kirlia dodged, causing the combo to shatter into pieces of ice. Leafeon used Magical Leaf, along with Kirlia's Psychic, to strike Cyndaquil and Mamoswine, defeating them.[1]
During the semi-final round, Nando sent Kricketune and Lopunny to battle Zoey's Mismagius and Leafeon. Zoey's Leafeon started off with Energy Ball, with Mismagius using Thunder Wave. Lopunny deflected their attacks with Jump Kick, whereas Kricketune's Bug Buzz weakened Leafeon. Lopunny danced around, powered by the Bug Buzz, which deflected Zoey's Pokémon's attacks. Zoey had Mismagius and Leafeon use Double Team, surrounding Nando's Pokémon. While Lopunny's Blizzard banished their illusions, this move caused Zoey's Pokémon to be in the spotlight.
Kricketune used Sing, to which Mismagius' Lucky Chant negated its effects. Lopunny went to use Focus Blast, which was countered with Leafeon's Leaf Blade. Kricketune went to use X-Scissor, whereas Mismagius launched Psywave. Lopunny took Kricketune away to evade Psywave and launched it, only for Kricketune to collide with Leafeon's Leaf Blade. Next, Kricketune used Silver Wind, which combined with Lopunny's Blizzard, turning the combo attack into snowflakes. Leafeon used Aerial Ace, powered with Mismagius' Psywave, making Leafeon look as it had wings. Lopunny went to intercept Leafeon, but was struck by Mismagius' Thunder Wave. Kricketune used X-Scissor and collided with Leafeon. When time was up, Nando lost more points than Zoey did, and the latter won the round.[2]
