Sue Sylvester (Jane Lynch) is the cheerleading coach to the Cheerios and the nemesis of Will Schuester (Matthew Morrison) and the glee club New Directions on "Glee." Tall, blond and invariably clad in an Adidas tracksuit, Sue is incredibly sarcastic, funny and never misses an opportunity to make a remark about Will's hair. She takes delight in foiling his plans and trying her best to disrupt his life. She firmly believes that any monies given to New Directions should rightfully belong to the Cheerios and goes so far as to place Santana Lopez (Naya Rivera), Brittany Pierce (Heather Morris) and Quinn Fabray (Dianna Agron) in the group in order to spy for her so she can better plot Will's downfall. Later, she gives New Directions' set list for Sectionals to rival Glee Club directors Grace Hitchens (Eve) and Dalton Rumba (Michael Hitchcock) hoping to ruin their chances of winning.
Sue's views are often forthright and controversial. She openly chastises and berates students whom she feels don't fit in, often pushing students out of her way when in a rage. Her views are expressed most obviously in her news segment on TV - "Sue's Corner."
She does have a soft heart underneath her harsh exterior. In the first season it is learned that she has a sister, Jean (Robin Trocki) with Downs Sydrome whom she regularly visits and has looked after from a young age. This close relationship leads her to allow another girl with Downs Syndrome, Becky Jackson (Lauren Potter) in to the Cheerios, later on giving her a role as her assistant. She detests those who view people with disabilities as abnormal and refers to disabled people as "handi-capable". Because of this, Sue is seen as more than just a one dimensional character who has no redeeming qualities.
Sue's finest hour comes when New Directions post online an embarrassing video of her performing Olivia Newton John's "Physical." Sue believes everyone is laughing at her and refuses to leave her house, only to have Olivia Newton John herself ask her to perform a new version of "Physical" as a duet. A delighted Sue accepts and wastes no time in rubbing it in the faces of her critics.
Throughout the series, Sue becomes a more and more likeable and at times, a sympathetic character. She even votes for New Directions at Regionals, defending them against the other judges' condemnations.
"I spent large segments of each day picturing you choking on food, and I recently contacted an exotic animal dealer because I had a very satisfying dream that I once shoved your face into one of those pink-inflamed monkey butts."
"I empower my Cheerios to live in fear by creating an environment of irrational, random terror."
"Ah, a chink in the armor, huh? I am going to create an environment that it so toxic, no one will want to be a part of that club. Like the time I sold my house to a nice young couple, and I salted the earth in the backyard so that nothing living could grow there for a hundred years. You know why I did that? Because they tried to get me to pay their closing costs."
