Aromatisse is Aria's second Pokémon, it was used in battle against Serena's Fennekin and Pancham. Aromatisse blocked Fennekin's Scratch with Reflect, allowing Delphox to retaliate with Mystical Fire. Aromatisse also blocked Serena's Pancham's Stone Edge. Aromatisse attacked with Charge Beam, but Pancham protected Fennekin by countering the move with Dark Pulse. After Serena's Fennekin evolved into a Braixen, Aria, posing as Arianna, wanted to end the battle. However, she received a call and canceled the battle, calling Delphox and Aromatisse in their Poké Balls.
