Rayquaza is a large, green, serpentine Pokémon that also looks like a missile. It has red-tipped, rudder-like wings on its shoulders and down its body, as well as similarly patterned fins at the tip of its tail. Yellow ring-like symbols run along Rayquaza's body, and it has an additional yellow ring on top of its head. This Pokémon has two limbs with three-clawed hands, and two long, flat, horn-like structures on its head, along with two shorter horns along its jawline. Its eyes are small and yellow with black pupils, it has prominent pink gums, and two noticeable fangs in its upper jaw.
Rayquaza can calm other super-ancient Pokémon, even in their Primal Forms. It is believed to have lived for hundreds of millions of years in the ozone layer, where it feeds on water and particles. Rarely seen by people, its appearance in flight can be mistaken for a meteor. Rayquaza can breathe in outer space. In the Alola region, it preys on Minior and consumes meteoroids, particularly Mega Stones. A Key Stone can summon Rayquaza, which boasts some of the strongest attack power among Pokémon, easily creating cyclones to overwhelm opponents. The Draconid people and those of Hoenn worshiped Rayquaza as the savior of the region, building the Sky Pillar in its honor. It is one of the longest-lived Pokémon species.
Forms
Rayquaza can Mega Evolve into Mega Rayquaza. As Mega Rayquaza, its body elongates and gains more features. Its head becomes longer with a Δ symbol appearing on its forehead. Its eyes now have yellow pupils and red irises, and black, shichishito-shaped markings trail behind them. Its red lips and teeth turn gold, and golden lines connect to those on its lower horns, which take on a broad, triangular shape. At the outer edges of its lower horns are long, golden, glowing tendrils ending in green, fin-like structures; these tendrils have ring patterns resembling the yellow markings on Rayquaza’s normal form. While flying, these tendrils give Mega Rayquaza a Δ-shaped profile. Its upper horns grow longer with a V-shaped gold line running over them, each having another glowing tendril ending in a circular shape with a spike. Along its body are golden, glowing orbs placed where its ring patterns used to be. Parts of its chin, neck, and serpentine body turn black. The fins along its body are marked with gold lines; the tail fins become entirely yellow and substantially longer. Particles stream from the long tendrils extending from its jutting jaw, controlling air density and humidity, allowing Mega Rayquaza to manipulate the weather. Its green hide sparkles with an emerald-like quality.
Mega Rayquaza was said to have been born from humanity’s wish for salvation, channeled through the Key Stone of a Draconid Lorekeeper. It was the first recorded Pokémon to achieve Mega Evolution. Inside Rayquaza’s body lies an organ containing the same power as a Mega Stone, named the mikado organ by a Devon Corporation scientist. By consuming meteoroids in the stratosphere, this organ accumulates enough energy for Rayquaza’s Mega Evolution. Mega Rayquaza can undo the Primal State of Groudon and Kyogre. As shown in the anime, Rayquaza can Mega Evolve without a Key Stone and is capable of destroying meteors larger than itself, such as the Grand Meteor Delta.
