Azelf (Japanese: アグノム Agnome) is a Psychic-type legendary Pokémon. It is not known to evolve into or from any other Pokémon.
Along with Uxie and Mesprit, Azelf is a member of the lake guardians, the Sinnoh region's Psychic-type legendary Pokémon trio.
Azelf is a small, grayish blue, fairy-like Pokémon. It has two tails that each have a red jewel on them. These are, presumably, two of the jewels which complement the Red Chain. Azelf has a partially cyan face with another red gem encrusted into its forehead. Azelf has a cone-shaped head with elf ear-like protrusions on each side.
Azelf is said to have hatched from the same egg as Mesprit and Uxie.
