Sinistea is one of the shortest Pokémon. It lives in a seafoam-green antique teacup with gold rims and a lacy face that changes with its feelings.
A lonely spirit of forgotten cold tea lives in homes and hotels, then evolves into Polteageist. It drains drinkers' energy, but they spit it out, and stirring it makes it dizzy.
A phony Sinistea is born when a Polteageist pours its tea into Diana's cup, then travels with the Rising Volt Tacklers. Allister also has one pour tea into possessed Ash's mouth.
Sinistea may combine sinister and tea. James Turner designed it as a poltergeist possessing a teacup, echoing the British tea culture that Galar is based on.
