| Flavor Text | 
|  | Sword | This Pokémon is said to have been born when a lonely spirit possessed a cold, leftover cup of tea. | 
Shield | The teacup in which this Pokémon makes its home is a famous piece of antique tableware. Many forgeries are in circulation. | |  | Sword | The swirl pattern in this Pokémon's body is its weakness. If it gets stirred, the swirl loses its shape, and Sinistea gets dizzy. | 
Shield | 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. |
