Super-ancient Pokémon

Groudon and Kyogre battle as Rayquaza arrives.

The weather trio is, for lack of a better defining characteristic of the three, the name of the legendary trio made up of Groudon, Kyogre, and Rayquaza. They are referred to in the games as the super-ancient Pokémon (Japanese: 超古代ポケモン super-ancient Pokémon), although the Japanese anime has applied this term to Fossil Pokémon as well.

Although several non-legendary Pokémon, notably Tyranitar and Abomasnow, have abilities that can alter the weather conditions, and the Golduck family is capable of having an ability that can stop them altogether, Groudon, Kyogre, and Rayquaza's abilities were the first sight of these weather-changing ones in the games. This makes them the only legendary trio to not share one universal ability.

Unlike Pokémon with moves like Sunny Day and Rain Dance, where the weather changes to another for only five turns, the abilities of the legendary trio cause their weather effect for the remainder of the battle, or until the weather is changed again in some way. Rayquaza's, however, only lasts as long as it remains active, and removes the battle effects of any weather on the field, leaving it to just be a pretty-looking environmental effect.

They do not appear to have a master, though Rayquaza seems to serve as the leader of the three internally. It was shown quelling a violent confrontation between the other two Pokémon during the events of Pokémon Emerald.

Strangely, this is the only legendary trio whose members do not all have the same base stat total; Groudon and Kyogre share a total of 670, while Rayquaza's is 680. This fits with its role as a mediator between Groudon and Kyogre.

Trivia

• The colors of the three members of weather trio are the primary colors of light, while colors of their Template:Shiny2 sprites (including the markings on Rayquaza) are the primary colors of ink.
• Kyogre, Groudon, and Rayquaza could be references to the Biblical Leviathan, a sea monster; Behemoth, a land beast; and Ziz, a giant bird respectively.
• The trio may also be a reference to the Japanese movie Godzilla, Mothra and King Ghidorah: Giant Monsters All-Out Attack.
• The trio may also reference Zeus, Greek God of the Sky (Rayquaza), Poseidon, Greek God of the Sea (Kyogre) and Hades, Greek God of the Underworld (Groudon). Incidentally, Zeus is the strongest of the three as well as the chief god, while Rayquaza acts as the trio's master internally.
