Rayquaza is the Sky High Pokemon, it is not known to evolve from or into any other pokémon. Rayquaza is the version mascot of Pokémon Emerald, appearing on the box art of the game. It serves to end the conflict between Kyogre and Groudon when Team Magma's leader Maxie and Team Aqua's leader Archie awakened them. Along with Kyogre and Groudon, Rayquaza is a part of the Weather trio, serving as its Trio master.
Rayquaza is a large, mostly green, serpent-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 ring-like symbols 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 has a prominent gumline, with only two discernible fangs on the tip of its upper snout; the other teeth seem to be covered completely by gum tissue. It has small, yellow eyes with black pupils, which resemble those of both Kyogre and Groudon.
