Stanley Kowalski -  The husband of Stella. Stanley is the epitome of vital force. He is loyal to his friends, passionate to his wife, and heartlessly cruel to Blanche. With his Polish ancestry, he represents the new, heterogeneous America. He sees himself as a social leveler, and wishes to destroy Blanche's social pretensions. Around thirty years of age, Stanley, who fought in World War II, now works as an auto-parts salesman. Practicality is his forte, and he has no patience for Blanche's distortions of the truth. He lacks ideals and imagination. By the play's end, he is a disturbing degenerate: he beats his wife and rapes his sister-in-law. Horrifyingly, he shows no remorse. Yet, Blanche is an outcast from society, while Stanley is the proud family man.
