Team Rocket are an organized crime syndicate in pursuit of evil and exploitation of Pokémon based in the Kanto and Johto regions with a small outpost in the Sevii Islands.
While its main focus is stealing or capturing, then selling, rare and strong Pokémon, it also funds and conducts cruel experimental research on Pokémon. Their oath, as posted on the wall of one of their many bases, is "Steal Pokémon for profit. Exploit Pokémon for profit. All Pokémon exist for the glory of Team Rocket." Their ultimate goal is to take over the world using Pokémon.
