Articuno is a large avian Pokémon with predominantly sky blue plumage and wings said to be made of ice. On its forehead is a crest that consists of three, darker blue rhombus-shaped feathers. It has circular red eyes, a short gray beak, and long, thin gray legs. Each foot has three forward-facing digits and one facing backward. On its chest is a mass of white, downy feathers. Its long, streamer-like tail is longer than its body and the same shade of blue as its crest.
