Aromatisse evolves from Spritzee when traded while holding a Sachet. It can emit a range of scents, from a pleasant fragrance that bolsters allies to a repugnant odor that saps an opponent's will to fight.
Aromatisse physically debuted in Battling with Elegance and a Big Smile! under the ownership of reigning Kalos Queen Aria, appearing throughout Pokémon the Series: XY, and another Aromatisse appeared in Pikachu and the Pokémon Music Squad, noticing a fight over a Pecha Berry. It was designed by Saya Tsuruta and can be seen as a parallel to Slurpuff, both Generation VI Fairy types that evolve from trading with a held item.
Aromatisse debuted as a Rare in the XY base set from 5ban Graphics, followed by a BREAKthrough Rare, a BREAKpoint Uncommon, and an Unbroken Bonds Rare. Prismatic Evolutions added a Common, and the Mega Evolution era's Perfect Order an Uncommon.
