Uxie

Uxie, known in Japanese as ユクシー (Yukushii), is a Psychic-type Legendary Pokémon introduced in Generation IV. It is part of the Lake Guardians, a trio that includes Mesprit and Azelf, found in the Sinnoh region. Uxie is a grayish-blue, fairy-like Pokémon with two long, leaf-like tails, each tipped with a red gem. It has a yellow face, and its eyes are always closed. Legend says that anyone who gazes into Uxie's eyes will have their memory erased. Uxie is known as the Being of Knowledge, and it is said that its emergence gave humans the intelligence to solve problems and improve their quality of life. In the Pokémon Mystery Dungeon series, Uxie is depicted as having the ability to create illusions and is credited with creating all knowledge in the Pokémon universe. It does not evolve and has appeared in multiple games, including Pokémon Platinum, Pokémon Black 2/White 2, and Pokémon GO. Uxie has also appeared in the anime, where it works alongside its fellow Lake Guardians to help the main characters.
