Unown is a Psychic type Pokemon introduced in Generation II. While it is not known to evolve into or from any other Pokemon, as of Generation III, Unown has 28 derivative shapes, chronicles in the Unown Mode in Generation II and the Unown Report in HeartGold and SoulSilver. There are 26 Latin alphabet characters, plus question and exclamation marks introduced in Generation III. In Generation II, its shape is determined by its individual values; in Generation III, it is determined by its personality value; from Generation IV onward, it is determined by a separate form identifier.
