Uxie (㠦㠯㠷㠼 YukushÄ«?, Yuxie), known as the Knowledge Pokémon, has a round head and a yellow "helmet" on it with a red jewel embedded in its forehead, and in its Sugimori art it appears to be sleeping, or closing its eyes in deep thought. Uxie's name comes from the word pixie, a small mythical creature, and "you", U being short for it. The other members of the Psychic-type Lake Trio, Mesprit and Azelf, represent "me" and "us", respectively. It is also a possibility that these three Pokémon are inspired from a trio of Arabian goddesses, Al-Lat (Azelf), Manat (Mesprit), and Al-Uzza (Uxie). This is further supported by their moniker as Mirage Pokémon (as mirages are something associated with the Arabian desert), and that the three appear to be wearing jeweled turbans, which are associated with Arabic royalty. Uxie's eyelids are also yellow, although they are obviously not part of the top of the head where the other yellow is. Its "helmet" resembles ahuman brain, since it is the Knowledge Pokémon. Like Mesprit and Azelf, its partners in the legendary trio, it has two tails with jewels embedded in them, and the only major difference between them is their heads and their faces. Of its trio, its stats and moveset seem to be on the defensive side. It is also believed that the mystic trio was all hatched from the same egg.[63] Uxie is found in Lake Acuity. Uxie chose Brock and is connected with him, like what Mesprit did to Dawn and like what Azelf did to Ash.

Uxie is referred to as "The Being of Knowledge". It is said that its wisdom can help humans improve their lives. Similar to the legend of the basilisk where the basilisk could cause death by a single glance, Uxie can cause a complete loss of memory by a single glance of its open eyes; hence, its eyes are always closed, even when it is moving or in battle. It uses its telekinetic abilities to figure out what's going on instead. Uxie is also seen in Pokémon Mystery Dungeon: Explorers of Time/Darkness as a legendary Pokémon that protects the Time Gear at Fogbound Lake. Not to well but Meh, THIS IS FROM A WIKI, I DO NOT OWN IT LIKE THE OTHER POKEMON ONES.
