Fandom
Giovanni serves as the Head of Team Rocket in the anime, never really shown taking action in field work, but rather sends the grunts and other members for that. Jessie, James, Meowth, Butch and Cassidy along with other members, are constantly striving to please him in their actions, usually without his compliance.
