Trivia

 * Considerably, Unown is the most highly prized possession in the game making it a huge stepping stone for players. It is because Unown often spawns in inaccessible areas, making it very hard to find. Only the most dedicated players would find this Pokémon.
 * Exclamation and question mark Unown forms are counted in unique Unown caught in medals, making it possible to obtain the gold medal without completing the alphabet.
 * Sprite of Unown N was updated on August, 2019, possibly making it less confusing with Unown Z.
