Keldeo is pony-like, with a large, feathery red mane, long, dark blue, ridged eyebrow-like features, and a single cream-colored horn that is slightly curved. The back of its head, as well as its neck, has light blue-and-white-spotted coloration with spiky edges at the lower portion. Its body is cream-colored, with blue hooves. Its blue-and-white-spotted, lifted and feathery tail is comparable to an elaborate feather in a cap.
