NEW POKÉMON DISCOVERED IN THE LAND OF KITAKAMI, THE SETTING FOR THE HIDDEN TREASURE OF AREA ZERO FOR POKÉMON SCARLET OR POKÉMON VIOLET

​​​​​​​Although It Bears a Resemblance to Sinistea, Poltchageist Is an Entirely Different Species of Pokémon

Bellevue, WA—August 22, 2023—Today, The Pokémon Company International announced the discovery of a new Pokémon: Poltchageist! This Pokémon was discovered in the land of Kitakami, the setting for The Hidden Treasure of Area Zero Part 1: The Teal Mask DLC for the Pokémon Scarlet or Pokémon Violet video games that launches exclusively on the Nintendo Switch family of systems on September 13, 2023. Poltchageist was featured in a new cinematic trailer that can be viewed here.

Poltchageist has a swirl pattern not unlike Sinistea’s—but unlike Sinistea, its swirl is not a weakness. After a target is sprinkled with some of Poltchageist’s powdery body or eats food dusted with it, Poltchageist drains their life-force and absorbs it as energy.​
