Shego is a villainess who operates as a criminal mercenary, working for Dr. Drakken as his chief enforcer and henchwoman. Since her main duty to Drakken entails stealing things on his request and protecting him from harm, she frequently engages Team Possible in battle, and although she is under contract with the scientist, Shego has occasionally worked with other villains as well, including Motor Ed and Señor Senior, Junior.
