Azelf is a small, gray-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":http://bulbapedia.bulbagarden.net/wiki/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.
