Romaji: Yabacha) is a species of Pokémon in the series of the same name. It is a Ghost Pokémon introduced in the eighth generation games, Pokémon Sword and Shield. It evolves into Polteageist when it is exposed to a Cracked Pot or Chipped Pot. The Cracked Pot will cause it to evolve the Phony Form, while the Chipped Pot will cause it to evolve the Antique Form.
Sinistea is a Pokémon said to be created when a lonely spirit possesses a cold, leftover cup of tea. The teacup that Sinistea lives in is a famous piece of antique tableware; seafoam green in color with a lacy pattern that resembles a face and gold rims. However, there are many forgeries in circulation. Antique Form Sinistea has a mark of authenticity on the bottom of the cup, whereas Phony Form Sinistea lacks it. This mark appears as a light grey emblem on the bottom inside rim of the cup.
The swirl pattern on Sinistea's purple body serves as a weakness. Should a Sinistea get stirred, the swirl will disappear and cause it to get dizzy. Sinistea can absorb the life-force of anyone who drinks it. While it can wait patiently, most of Sinistea's opportunities end up being short, as it tastes so bad that it is spat out immediately. Sinistea inhabits hotels and homes. Poltchageist bears a resemblance to Sinistea, although the two species are biologically unrelated.
