Martha Dunnstock

Martha Dunnstock, sometimes known as Martha Dumptruck by The Heathers, is a major character in the 1988 film, Heathers and is portrayed by Carrie Lynn. Martha is relentlessly teased throughout most of the film.

The first time Martha is shown, Heather Chandler forces Veronica Sawyer to forge a love note under Kurt Kelly's name. When Martha brings the note to Kurt, he laughs in her face and she storms out of the cafeteria. Veronica did not laugh, though and she went over to the stand looking fed up, probably realizing that The Heathers were just toxically influencing her. Heather Chandler grabs her and says “You wanted to be a member of the most powerful clique in school”.

Early Life
Not much is said about Martha's early life other than being shown that she was a childhood friend of Heather Duke.

Appearance
Martha is very overweight, has brown hair, cut short and dresses unfashionably. Living in a shallow society, the poor girl goes through a lot for not fitting the mold of thinness. The Heathers do not respect her for her overweight self and Veronica, becoming a Heather, also says Martha is fat. She could’ve been becoming a Heather because Heather Chandler And Veronica’s poses were exactly the same. After they keep bullying her she runs out, crying. Veronica keeps on telling Martha that she is sorry but Martha keeps crying saying that she’s “lying about being sorry”.

Personality
Quiet, afraid, shy and emotionally bruised. Martha is one of the most tragic characters, and definetely the one who has it worse. She is a sensitive girl who dreams of loving and being loved, but for being overweight she is shunned and mistreated by others and she’s too afraid to stand up for herself.

When she can't take it anymore, she attempts suicide, but luckily survives.

In the ending of the film when Veronica befriends her, we finally hear her voice and get a good glimpse of the sweet, sensible young woman who still keeps hoping for the best, despite everything she went through.

Attempted Suicide
Martha is seen sitting in the gym after the murders of Heather Chandler, Kurt Kelly and Ram Sweeney. At first, it appears she is attending a sporting event but she is really alone.

She spills a drink on herself and then the scene flashes to Martha walking into traffic with a suicide note pinned to the front of her shirt.

Luckily, she survives but is badly injured and ends up being wheelchair bound. Heather Duke continues to mock her for trying to "act popular" by committing suicide like Heather, Kurt and Ram did, for which Veronica slaps Heather Duke.

Heather Duke
Martha and Heather Duke were close friends during their childhood. It isn't explained why the friendship ceased, but it is made clear that Heather Duke does not want anyone at Westerburg High to know about their past friendship.

Veronica Sawyer
At the end of the film, free at last of The Heathers's toxic influence, Veronica invites Martha to hang out on prom night and watch movies with her. This is the start of their friendship.
