Blanche DuBois
The protagonist. A former Southern belle and schoolteacher who arrives in New Orleans with nothing left. She lies, performs, and drinks to survive. Her mental state deteriorates across the play as Stanley strips away every defense she has.
Stanley Kowalski
Stella's husband and Blanche's primary antagonist. He's physically powerful, socially dominant, and deeply suspicious of Blanche from the start. He investigates her past, destroys her relationship with Mitch, and ultimately assaults her.
Stella Kowalski
Blanche's younger sister. She left the old Southern world behind and built a life with Stanley. She loves him despite his violence. Her final choice not to believe Blanche is what sends Blanche to the institution.
Harold 'Mitch' Mitchell
Stanley's friend and Blanche's romantic hope. He's more sensitive than the other men and genuinely interested in Blanche. Once Stanley tells him the truth about her past, he confronts and rejects her.
Allan Grey
Blanche's deceased husband. He never appears in the play, but his suicide haunts every scene. Blanche discovered he was gay, said something cruel, and he shot himself. Her guilt over that moment shapes everything she does.
