Team Rocket is a major "crime syndicate" in the Pokémon franchise. Their basic plan is to exploit Pokémon for economic gain and political control. They primarily are hampered by their own bumbling and the intervention of young Pokémon trainers.
Team Rocket's original (and most infamous) leader is q.v. Giovanni. Several other named characters have appeared in the ranks of Team Rocket - thought the anime characters probably are better known than the (mostly different) video game characters. Meowth, Jesse, and James appear prominently in Pokémon Yellow.
Team Rocket's well known tag line upon failure, "Blasting Off", frequently is satirized.
