The Team Aqua is one of the villainous groups from Pokémon Ruby/Sapphire/Emerald. Their goal is to awaken Kyogre, the legendary Ocean Pokémon, so they can use it's powers to expand the sea, as they believe this will benefit humans and Pokémon alike. They are bitter rivals with Team Magma, because they have opposite goals. The team is headed by Archie and his two immediate subordinates Matt and Shelly. All of their grunts dresses sailor uniforms, and they prefer to use poison/dark and water-type Pokémons, such as Zubat, Poochyena and Carvanha.
Differing greatly from other villainous groups in the series such as Team Rocket and Team Galactic, Team Aqua can be seen more as a group of fanatics than real criminals, as they have a seemingly more altruistic goal instead of working for their personal gain. They are also much more organized, since their grunts follow direct orders from their superiors instead of having their own agenda like Team Rocket.
