Unown (Japanese: アンノーン Unknown) is a Psychic-type Pokémon. While it is not known to evolve into or from any other Pokémon, as of Generation III, Unown has 28 derivative shapes. There are 26 Latin alphabet characters, plus two punctuation marks: ? (question mark) and ! (exclamation mark). In Generation II, its shape is determined by its individual values, whereas in Generation III and beyond, it is determined by its personality value.
Unown are floating, flat, eye-shaped Pokémon with appendages that make them resemble letters. They are black all over. All alphabetic Unown have fully open eyes while the two punctuation Unown have half-closed eyes.
