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, doing the same in Pokémon Emerald that Lugia does in The Power of One.

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.
