The energy that fills its body spills forth as seawater. Its body composition becomes nearly a match for seawater, and its blue skin glows like a sapphire. Its body is half-translucent, and a golden light glows from within it.

Primal Reversion is a transformation sequence similar to Mega Evolution that only Groudon and Kyogre are known to use at the moment. Kyogre regains its immense power and becomes Primal Kyogre. It gains the Primordial Sea ability, and gets its Attack Stat is improved significantly. Its Sp Atk and Sp Def stats are already high prior to transformation but both are raised considerably increased without lowering other stats. It's size almost doubles after transforming.

Primordial Sea is Kyogre's exclusive ability. This ability changes the weather condition to an oppressive heavy rain. It is not possible to change the weather condition during heavy rain (leaving aside the efforts of an exceedingly small number of Pokémon). It's effects are similar to Rain Dance with the additional effects below:

• The weather stays active as long as the ability-bearer remains in battle, but stops when the Pokémon is switched out.
• Fire type attacks "fizzle out" and have no effect.
• The heavy rain cannot be replaced by a regular weather condition - in other words the moves Hail, Rain Dance, Sunny Day, and Sandstorm, and the abilites Drizzle, Drought, Sand Stream, and Snow Warning will fail.
• The abilities Cloud Nine or Air Lock are still able to bypass the effects of Primordial Sea

Origin Pulse is Kyogre's exclusive move. This slams foes with water massed into ballistic orbs which can hit multiple opponents.
