Extremely rare in our world, this sphere thing hails from his own dimension, he thrives exponentially. If Unown moves to Sphereworld, he tends to meet the others and becomes a new color of the spheres. Otherwise, the species tend to orbit around each other. Unown species come in many different shapes. The shape the one the other spheres know and love prefers the most is the letter X. He is Color #30||”|

Unown is a Poke-protagonist of Luxor. Like his friends, he's a member of the Sphere Club. While he is not known to evolve into or from any other Pokémon from his own franchise, as of Generation III, Unown has 28 derivative shapes, chronicled in the Unown Mode in Generation II and the Unown Report in HeartGold and SoulSilver. There are 26 Latin alphabet characters, plus ? (question mark) and ! (exclamation mark) introduced in Generation III. In Generation II, his shape is determined by his individual values; in Generation III, he is determined by his personality value; from Generation IV onward, he is determined by a separate form identifier.
