Heather Chandler, portrayed by the late Kim Walker, is the first female antagonist of the cult classic film Heathers. She is the deceased leader of the most popular and powerful clique at Westerburg High known as The Heathers. Heather's color is red, symbolizing her power over, not only the Heathers, but the entire Westerburg High student body.
Heather was the leader of the Heathers clique and ruled Westerburg High with an iron fist. She claimed that being the leader of the Heathers is what she would have wanted if she wasn't already the leader. She claimed to be worshipped at Westerburg High despite seemingly being a year younger than most of the other popular students. with the entire student body wanting her for either a “friend or a fuck.”
Little is known of Heather's early life. It is only known that she was the founder and lead member of The Heathers.
Heather is an attractive girl with shoulder-length, curly, strawberry blonde hair, fair skin, and pale green eyes. Standing at around 5'4", she's taller than Veronica and Heather Duke, but shorter than Heather McNamara. She's always seen wearing her signature color red in some fashion.
Heather chandler is very aware of how people view her and has accepted that. She’s very demanding, self-aware, cold-hearted and knows what she has to do to stay the so-called “queen bee”. Heather is not a nice person, in Veronica’s own words she’s a “mythic bitch” and she seems to own it. She’s associated with the colour red, symbolizing that she rules the Heathers and Westerburg High, as red associates with power. The only time we see Heather show any weakness is after she's coerced into performing sexual acts on a Frat boy at college party, when she rinses her mouth in the bathroom, and spits at her reflection in the mirror. She had some degree of shame or insecurity she only shows when she's alone.
Veronica greatly embarrasses Heather at the Remington University party by refusing sex from one of the guys hosting the party and eventually throwing up on their hallway carpet. Heather vows to destroy Veronica's reputation after this and tells Veronica that she either needs to switch schools or she's dead come Monday. Veronica and J.D. show up to Heather's house the following morning to offer her a "hangover cure." Veronica made a concoction of milk and orange juice that would make Heather puke her guts out, while J.D. made a more sinister concoction of liquid drain cleaner with the intention of making Heather extremely sick.
Veronica rejects J.D.'s idea but accidentally grabs his cup instead. J.D. notices this and says nothing other than to let him hold the cup. In Heather's room, the duo offers her the cup which she refuses. J.D. calls Heather a chicken which irritates her and she chugs the cup of drain cleaner. Heather starts choking, muttering the words, "Corn...nuts!" before falling into a glass coffee table, dead. Veronica and J.D. panic, covering up her death to make it appear as if she had committed suicide instead.
Heather Chandler's ghost haunts Veronica's dreams later on in the film, complaining about her "boring" afterlife in heaven
Of all the members of the Heathers, Veronica Sawyer appears to be Heather Chandler's favorite. She allowed Veronica into the group with the sole intention of using her skills to her advantage, which she does, but seems to enjoy Veronica's company as well. Heather insists that Veronica helps her with the lunchtime polls and even invites her to the Remington University party, excluding both Heather Duke and Heather McNamara. Veronica later plays a role in Heather Chandler's accidental murder.
Heather Chandler does not appear to like Heather Duke at all, constantly bullying her and talks down to her treating her like she's an idiot. She treats Heather Duke's bulimia like a joke and often hits Heather Duke’s ball out during croquet just to spite her. It is suggested that Chandler can see beyond the personality Duke shows at the start of the film, as later in the film Duke copies the ex-queen's personality. As a ghost/dream figure, Heather Chandler talks to Veronica about how she is better than Heather Duke.
Not much of a relationship is shown between Heather Chandler and Heather McNamara, though Heather Chandler seems to trust her enough to allow her into her clique and does not appear to bully her like she does to Heather Duke. Heather Chandler and Heather McNamara wouldn't be considered as close but they appear to have a stable relationship.
Heather Chandler and Peter Dawson briefly dated before the movie started. Peter tells the class during Heather's memorial that she broke up with him because he was too boring.
