Kyogre

Kyogre (カイオーガ, Kaiōga) is a fictional creature in the Pokémon media franchise.

Creature description
Kyogre is a legendary Pokémon that made its debut in the 3rd Generation games Pokémon Ruby & Sapphire for the Game Boy Advance. Kyogre, a winged whale, is the "cover mascot" of the Sapphire Version and the opposing counterpart to the Ruby Version's cover mascot Groudon. Kyogre embodies all the oceans of the world just as Groudon embodies the land and dryness. Since it fought Groudon a long time ago, it has been sleeping in a deep trench. Team Aqua, a rival of Team Magma, have a desire to capture Kyogre and use it's power to make Hoenn have more seas than land, while Team Magma does the opposite, but with Groudon.

As a Poké Ball Pokémon
Super Smash Bros. Brawl is the first Super Smash Bros. game to include Kyogre, as Kyogre didn't exist when the first two games were made. When summoned from a Poké Ball, Kyogre appears to fly around using Hydro Pump, where it shoots water out of its mouth. While Kyogre does damage when it is touched, but it's attack does no damage and is like Mario's F.L.U.D.D and Squirtle's Water Gun and is useful for stopping recoveries. It tends to target one character until he disappears, making it a godsend on small crowded maps. Kyogre is a rare Poké Ball, as are other legendaries.
