Articuno is a large avian Pokémon with predominantly blue plumage and large wings said to be made of ice. It has a head crest that consists of three, darker blue rhombus-shaped feathers on its forehead and circular red eyes. Its beak is short and gray, and its long, thin legs are the same color. It has a long, streamer-like tail that is longer than its body and the same shade of blue as its crest. Articuno lives in cold, isolated locations, such as mountain peaks.
