While it is not known to evolve into or from any other Pokémon, Kyogre can undergo Primal Reversion and become Primal Kyogre if it holds the Blue Orb.
Kyogre possesses the ability to expand the oceans. In ancient times, it came into conflict with Groudon, a Pokémon with the ability to expand continents. In Pokémon Sapphire, Emerald, and Alpha Sapphire, Kyogre is sought after by Team Aqua as part of their plot to create more habitats for aquatic Pokémon by raising the sea level.
Kyogre is the game mascot of Pokémon Sapphire and its remake, Pokémon Alpha Sapphire, with Kyogre appearing on the box art of Sapphire and Primal Kyogre appearing on the box art of Alpha Sapphire.
Kyogre is a massive, whale-like Pokémon with two big pectoral fins, each with four white square-shaped nails. It has a deep blue body and a white chin area with two small spikes protruding under it. Above each eye are two white, oval-shaped spots. Kyogre has red stripes around its chin, eyes, dorsal fins, and torso. These stripes glow when Kyogre is brimming with power. The tail is tattered with four trailing parts, with the inner ones being smaller than the outer. Its eyes are small, yellow, and shadowed with black.
Primal Kyogre retains its general body structure but grows to more than double the size of its base form. Its main skin color becomes a darker shade of blue, the red markings along its body become light blue, and its eyes glow yellow with orange irises and orange-red pupils. The markings on its pectoral fins slightly change to form α symbols, which connect to its outer nails with red markings connecting the inner nails. Every part of its skin that was white in its base form becomes clear and translucent, with the large ovals on its head now connected to clear markings stretching from its tail to its forehead, where another α symbol is formed. The trailing parts of its tail grow longer and gain translucent webbing, and the areas between its pectoral fin markings also become clear. The translucent parts of its body reveal organ-like structures that glow with a mysterious light; it has a large "organ" at the center of its body, two smaller ones aligned with the large oval markings, and two more located in its pectoral fins. In the anime, Primal Kyogre is said to have widened the seas by a large margin simply by taking a swim.
Kyogre is said to be a powerful Pokémon, having control over the element of water and rain. It is said to have expanded the seas and is hailed as a savior for quenching areas of the world plagued with drought. Kyogre is normally calm and peaceful, but if it meets its rival, Groudon, Kyogre will engage in a cataclysmic battle against it. In the Mystery Dungeon series and core series, Kyogre is able to fly. Kyogre generally lives deep in the ocean and is said to rest in a deep trench. Kyogre is the only known Pokémon capable of learning the move Origin Pulse.
In The One That Didn't Get Away!, a Kyogre had been poisoned and was being pursued by a Pokémon Hunter and his underlings. However, Lana was able to feed it some Antidote, restoring its health and allowing it to defeat the hunter. However, Kyogre was still enraged because of the hunters' action, forcing Lana to reel it in with her fishing rod and have her Primarina sing to it in order to calm it down. After Lana calmed Kyogre down, it thanked her for restoring its health and calming it down before leaving peacefully.
Kyogre debuted in the opening sequence of Jirachi: Wish Maker, where it was seen swimming across the ocean near the seabed.
In The Cavern, a wild Kyogre was awoken by Archie inside the Seafloor Cavern, who used the Blue Orb to turn it into its Primal form. It escaped the Cavern and swam through its surrounding waters and surfaced above the ocean before creating a massive storm, threatening to destroy Hoenn. It was last seen attacking Archie and other members of Team Aqua when he tried to calm it down.
A Kyogre briefly appeared as a silhouette in GOTCHA!.
After being released from a Poké Ball, Kyogre opens its mouth and squirts out a stream of water. The water is non-damaging but causes characters to be knocked back with extreme force. Touching Kyogre's body will do damage. Kyogre also appears as a trophy.
"A Sea Basin Pokémon. It brought down heavy rains, which formed seas and relieved droughts. It is usually found slumbering at the bottom of an ocean trench. Its attack Sheer Cold is a technique so powerful, it causes any opponent it strikes to faint instantly. In battle, it causes clouds to form and drenches the area in rain. It once had a fierce battle with Groudon."
Kyogre returns as a Poké Ball summon with faster movement as well as a longer time and more KO ability. In these games, it can also appear from a Master Ball.
Kyogre trophy in Super Smash Bros. for 3DS
Kyogre also appears as a trophy in both versions of the game.
NA: This Water-type Pokémon roughly resembles an orca whale, though its large fins also look a bit like hands. Be wary of its Hydro Pump attack, which is capable of sending you flying off the stage. Even worse, it will chase after you, making it even harder to recover from the attack.
PAL: This orca-like Water-type Pokémon is known for the distinctive shape of its fins and the red markings along its body. It will use Hydro Pump to send fighters flying off the stage, and then proceed to chase after them to make recovering from the attack a nightmare.
Kyogre returns as a Poké Ball summon, retaining its behavior from past games. It, along with Primal Kyogre, also appear as Spirits.
Pokémon Pinball: Ruby & Sapphire: Kyogre is the focus of the second Bonus Field on the Sapphire Field. Kyogre will first use Sheer Cold to freeze the ball in place. It will then create whirlpools to trap the ball further. Finally, it will dive into the water to evade being hit completely. However, air bubbles will appear where it is about to rise out of the water. Kyogre must be hit 15 times in three minutes to win. After beating the round twice, Kyogre will be captured.
Kyogre and Groudon are the only Pokémon that are game mascots to appear on the original pair and remade pair's boxart in their base forms and their alternate forms, respectively.
Kyogre may be modeled after the Earth's oceans and may also be a personification of the ocean. Its conflict with Groudon is similar to that of Leviathan and Behemoth, who would start a battle that would kill them both at the end of time. Like Kyogre, Leviathan is associated with the sea, and the Hebrew word for Leviathan is now used for whales in Modern Hebrew, which may be why Kyogre's appearance also draws inspiration from cetaceans, especially the orca. However, Leviathan does not resemble Kyogre in traditional depictions.
Kyogre may be a combination of 海 kai (ocean) and orca (a species described as a whale, but is more closely related to dolphins). Notably, it may also involve 海王 kaiō (king of the sea), which are the first two characters in 海王星 Kaiōsei (Neptune).
