Sinistea is a Pokémon said to be created when a lonely spirit possesses a cold, leftover cup of tea. It is one of the shortest Pokémon in existence. The teacup that Sinistea lives in is a famous piece of antique tableware; seafoam green in color with gold rims and a lacy pattern that resembles a face (and functioning as one, being able to change to express emotions). However, there are many forgeries in circulation.
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. The Antique Form of Sinistea is highly sought after by certain enthusiasts. These collectors dedicate considerable time and effort to prepare the perfect tea and teacup, hoping that a Sinistea will come and possess their selections. Poltchageist bears a resemblance to Sinistea, although the two species are biologically unrelated.
Forms
Sinistea has two separate forms: Phony Form and Antique Form. Telling either of these forms apart requires careful inspection; Antique Form Sinistea has a stamp of authenticity on the bottom of its cup, whereas Phony Form Sinistea lacks it. This stamp appears as a teal-colored emblem on the bottom inside rim of the cup.
It absorbs the life-force of those who drink it. It waits patiently, but opportunities are fleeting—it tastes so bad that it gets spat out immediately.
Sinistea has two separate forms: Phony Form and Antique Form. Its form is maintained through Evolution into Polteageist and cannot be changed.
The Antique Form is rarer and has a stamp of authenticity hidden on the underside of its base. The only functional difference between the two forms is the Evolution item used by Sinistea to evolve into Polteageist: Phony Form Sinistea requires a Cracked Pot, while Antique Form Sinistea requires a Chipped Pot.
Antique Form Sinistea does not obey typical form inheritance rules when breeding, and therefore cannot produce Eggs that contain Antique Form Sinistea. All Sinistea that hatch from Eggs will always be Phony Form, regardless of the parent's form.
In Japanese, the names of Sinistea's forms use 「フォルム」 form, the term otherwise primarily used in the names of forms localized as Forme in English.
In the mobile version of Pokémon HOME, Sinistea is one of few Pokémon that can be "rotated" when viewed in the Pokédex, which replaces its render with a version viewed from behind so that its form difference can be seen.
The Sinistea and Poltchageist lines are the only convergent pairing that share a type and Egg Groups with each other, as well as the only ones with multiple forms.
Origin
Sinistea is based on a ghost (possibly a poltergeist, a mischievous ghost that possesses objects) possessing a cup of tea,[2] which has historical and cultural significance in the United Kingdom, the country Galar is based on. The way Sinistea holds its own cup references a way of holding a teacup with one's pinky finger sticking out,[3] which is commonly and erroneously believed to be part of tea drinking etiquette. Additionally, the bit of tea hanging from Sinistea's rim resembles both a tongue and a tea bag tag.
Sinistea's forms may be based on porcelain forgeries. One way porcelain makers historically combatted forgeries was to create a stamp of authenticity on their products, hence the stamp under Antique Form Sinistea.
Name origin
Sinistea may be a combination of sinister and tea.
Yabacha may be a combination of やばい yabai (dangerous; terrible) and 茶 cha (tea).
