Matiére, operating under the aliases Emma and Essentia, features in the Kalos-region episodes of the animated series. She begins as secretary to Looker, an agent of the International Police. Abandoned as a child, Matière was raised by Mimi, the director of an orphanage sheltering other displaced children; this community formed her sole family. Team Flare's destruction of the orphanage deeply affected her, leading her to join Looker's investigations to oppose the group. Serving as Looker's assistant, Matière adopts the covert identity "Essentia" utilizing specialized Essentia Armor. This armor grants her the ability to directly command Pokémon, markedly boosting her operational effectiveness. Her Essentia persona serves both tactical objectives and personal motives stemming from the orphanage's loss, driving her confrontations with Team Flare and quest for retribution. Her development centers on reconciling her orphanage origins with her current role. The orphanage's destruction fuels her commitment to fighting Team Flare, while her alliance with Looker structures her investigative and combat duties. The Essentia Armor embodies this evolution, merging her past and present identities.
