7. Sue Sylvester - Glee
The school cheerleading coach of William McKinley High School is a TV bad guy with the silver tongue. Not only is she the protagonist of the show competing with the school choir for funding, but shes also very, very mean. Her one liners, quips and imaginative put downs to both pupils and faculty members are always callous, nasty and spiteful. She isnt interested in anything else except the success of her Cheerios and will do anything to win. Bribery, blackmail and back-handed dealings are the order of the day and Sue Sylvester is also very well rehearsed in sabotage and trickery. Bad to the bone and without many glimpses of morality in her personality she is as ruthless as they come.
