Unown

Unown appeared in 1999 video game called Pokémon Gold & Silver. Unown is a Symbol Pokémon. Unown can be found in many different shapes that resemble ancient writing. It's not known which came first.

Unown is a flat, thin Pokémon shaped like an eye with appendages that make it resemble a letter or a punctuation mark. It is entirely black, except for its white sclera. All 26 alphabetic forms of Unown have fully open eyes while all the four punctuation forms have half-closed eyes. Though each of its forms has a counterpart in the Latin alphabet, Unown is said to resemble ancient writing and hieroglyphs. It is a mystery whether Unown predates or postdates written language, and therefore which one is based on the other.
