Rayquaza is a large, green, flying serpentine-like creature with red-tipped, rudder-like wings on its shoulders and down its body, and similarly-patterned fins on the tip of its tail. Yellow rings run across the length of Rayquaza's body and it has an additional yellow ring on top of its head. Rayquaza has two limbs with three-clawed carpals, and two long, flat, horn-like structures on its head, with two smaller horns below them. Rayquaza appears to have a prominent gumline, with only two discernible fangs on the tip of its upper snout, the other protrusions in its mouth apparently from pointed gums. It has small, yellow eyes with black pupils. Its eyes and markings resemble those of both Kyogre and Groudon.
