Character: Unknown

Unown is a hieroglyph-like symbol with 28 different forms, based on the letters of the Latin alphabet, a question mark, and an exclamation point. They always have the similarities of a flat body with black color and one medium-size eye. They always reside in mysterious chambers, only with other Unown, always stuck on walls.

Unown is featured in Spell of the Unown as the main antagonists. The Unown create an Entei to befriend a young girl and grant all of the girl's wishes: in the girl's case, turning the town she lives in into crystal. Ash and friends convince the girl that Entei is not her true father, since her father was lost on an archeological dig in an Unown temple. The Unown, overpowered by the girl's current thoughts, became unable to control their powers and larger areas were turning into crystal. Entei saves them all by attacking the Unown, sending them all back to their dimension. It has also been revealed that Dialga and Palkia live in the same dimension as the Unown.
