#480, #481, and #482 in the National Pokédex, Uxie, Mesprit, & Azelf are the Knowledge, an Emotion, and the Willpower Pokémon, respectively. Created by Arceus at the beginning of all things to calm Dialga and Palkia, the trio are said to have taught humans of their respective emotions, with their connection to the mind making them Psychic-types. Now, they each inhabit a lake in the Sinnoh region, earning them the collective name of the Lake Guardians. You can spot them yourself on the Spear Pillar stage!
