Quoted by Bulbapedia
Team Rocket (Japanese: ロケット団 Rocket Group) is a highly organized criminal syndicate "in pursuit of evil" headed by Giovanni (called "The Boss" by his underlings) and based in Kanto. Its main focus is in stealing or capturing, then selling, rare and/or strong Pokémon, but it also conducts cruel experimental research on Pokémon. Its final goal is to take over the world using Pokémon.
