From Bulbapedia, the community-driven Pokémon encyclopedia.
The lake trio is a term used to describe the legendary trio residing in the three lakes of Sinnoh: Uxie, Mesprit, and Azelf. They are meant to represent knowledge, emotion, and willpower, respectively. They are based off of the Imperial Regalia of Japan: the Yata no Kagami (wisdom), Yasakani no Magatama (benevolence), Kusanagi (valor).
Unlike previous trios, all three of the lake trio are of a single type, the Template:Type2, though like the others, they share an ability: Levitate. According to legend, when Arceus created the universe it created Uxie, Mesprit, and Azelf, and therefore is believed to be their master. According to one of Azelf's Pokédex entries, all three of them were born from the same egg.
It is interesting to note that each of the members of the lake trio has one of the qualities of the Abrahamic God: Uxie is omniscient, Mesprit is omnipresent, and Azelf is omnipotent. They could also be equated to, respectively, the Greek/Roman deities of Athena/Minerva, Poseidon/Neptune, and Zeus/Jupiter. It should also be noted that parts of their name come from fantasy creatures, pixies, sprites and elves, respectively. The other parts of their names come from pronouns: you (Uxie), me (Mesprit), and us (Azelf).
The members of the lake trio are tied for the lightest legendary Pokémon, and are second for the lightest of all Pokémon (after Gastly and Haunter).
- As seen in the pictures below, the two circles in each of the Pokémon's caves are the relative positions of the other two, although the meaning of the shapes of the puddles is unknown.

- The lake trio is the only trio whose members are all Template:Type2, and the same type for that matter. However the legendary birds and the dragon trio share their secondary types.
- The lake trio are the first set of legendary Pokémon since the legendary birds to have their names changed for the English language versions of the game - from Yuxie, Emrit, and Agnome to Uxie, Mesprit, and Azelf.
- The lake trio also helps the player through the Distortion World.
- The lake trio contains the three subtractive colors of yellow (Uxie), magenta (Mesprit) and cyan (Azelf).
- The lake trio also resemble Sonic, Tails, and Knuckles from the Sonic the Hedgehog games.
