The Unown Dex is a Pokédex upgrade present in Generation II. It is designed to display all 26 different types of Unown and the word that is associated with each form. The Unown Dex does not list the Unown in any specific order; rather, it lists them in the order in which the playercaptures them. After catching all 26 types, however, the forms will be reorganized alphabetically. Upon the player's capture of at least three different Unown and exiting the Ruins of Alph, a scientist will upgrade the player's Pokédex to support this mode. Ultimately, completing the Unown Dex also allows a player with a Game Boy Printer to print out the Unown sprites and text.
