Stanley Kowalski: A factory worker, aged 28 - 30. Stanley is more ambitious than any of his friends. He is childish; he only cares about what he wants and is very rude. He is so concerned with getting his own way -- and hurting Blanche -- that he has no compunction about hurting Mitch, his friend, by telling him the truth about Blanche. He is a very dominating: he overpowers his timid wife, Stella, constantly, to keep her from leaving him. He does the same to his friends when he wants to. Stanley is also incredibly protective of Stella: he doubts everything about Blanche from the beginning, and tries to make sure that he and Stella are not being tricked by a con artist. He is very proud, and is enraged when Blanche calls him "common," or a "Polack." He seems incapable of subtlety, and does everything whole-heartedly: he loves Stella thoroughly and hates Blanche vehemently and he hadn't trusted Blanche and he wanted to know what happened to Belle Reve or where the money went if their ranch was sold: [“STA: Kde sú teda peniaze, ak je dom predaný? STE: Nie je predaný – stratený, stratený! STA:Pozri sa na toto! Myslíš, že si to kúpila z učiteľského platu?.... STA: Pozri sa na tieto perá a kožušiny, v ktorých sa sem prišla cifrovať! Čo je to tu? Šaty z pravého zlata! ... STA: Mám známeho, ktorý pracuje v tomto fachu. Zavolám ho, aby to ocenil. Stavím sa, že do týchto cárachov investovala tisíce dolárov!“ pg. 26-27]

Stanley is honest to the point of brutality, and he does not care about offending others, -- he even brags to Mitch about raping Blanche. He despises Blanche becauses she is the opposite of his honesty; she thrives on illusion and pretense. His hatred of Blanche is so great that he rapes her, causing her final mental breakdown.
He is also full of cynicism:[BLANCHE: ''Túžila som po komplimente, Stanley.
STANLEY: Na také veci nie som.BLANCHE: Na aké veci?ST ANLEY: Na komplimenty ženám, pokiaľ ide o ich výzor. Nikdy som nestretol ženu, ktorá by nevedela, že vyzerá dobre aj bez toho, aby jej to niekto povedal a podaktoré veria väčšmi sebe ako inému. Raz som bol na rande s jednou fiflenou, ktorá mi povedala: "Jasom čarokrásny typ, ja som čarokrásny typ! "Povedal som jej: "No a čo''.pg:29]

Stella Kowalski: Stella is the connecting figure to two different worlds - the supposed
royalty world of Blanche DuBois and the more common world of Stanley Kowalski. Stella is five years younger than Blanche, about 25, and has been submissive to her for her entire life. Blanche and Stanley both attempt to influence her, and they succeed, to a degree. Stella said "Mr. Kowalski is too busy making a pig of himself to think of anything else!" This statement shows a direct influence from Blanche on Stella, as Stella never would have said that if she was alone. However, Stanley pulls his weight as well. He reminds her of all the wonderful times and nights they had together before Blanche came. He also succeeds in convincing her that his side of the rape story is the true one, which is the true goal of the power of influence within the book. Stella is the only place where a connection between Blanche and Stanley could occur. She is a mix of the two worlds. She still has many of the qualities instilled in her at Belle Reve, yet she does not let that get in the way of her having some fun. As she is so entangled between two completely opposite worlds, she is stuck and eventually, is forced to side with one of the two.
She is not strong, and therefore the "winner" of the battle is the one who gets her to side with them, Stanley.

Stella and Blanche loves each other very much,their love is pure emotion,light in the dark reality:[BLANCHE:" Stella, ach, Stella! Stella, hviezdička moja! Začne hovoriť s horúčkovitou živosťou, ako by sa bála, že nastane ticho a budú musieť začať rozmýšľať. Obe sakŕčovito objímajú.BLANCHE: A teraz dovoľ. nech sa na teba pozriem. Ale tysa na mňa nedívaj, nie, Stella, nie, nie, nie. až neskôr, až
ked sa okúpem a odpočiniem si. A zahas tú lampu! Zahas ju! Nechcem, aby si ma videla v tom nemilosrdnom svetle! Stella sa smeje a vypne svetlo. Pod' nazad ku
mne. Ach, bábätko moje! Stella! Stella, hviezdička moja!
Znova ju objíme. Už som myslela, že sa nikdy ne. vrátiš na toto strašné miesto! Čo to tu táram! Prepáč, nechcela som to 'povedať. Chcela som byť slušná a povedať - Ach, aká krásna poloha a podobne - Ha - ha - ha! Prepánajána! Ešte si mi nepovedala ani slova!"pg:14-15]

Harold Mitchell (Mitch): A friend of Stanley's from the plant. The two are about the same age. Mitch falls in love with Blanche, and wants to marry her. He is very sensitive. There are two reasons for this: the death of the girl he loved in his youth, and the terminal illness of his mother, who has no more than a few months to live. This sensitivity makes him feel very awkward sometimes. Mitch is, in Blanche's words, "capable of great devotion:" he wants to stay home to make sure his mother is alright, and is so concerned about her that it hampers his enjoyment of the card game with his friends. He has a very close relationship with his mother, exemplified by the fact that he tells her about Blanch and his great concern for her. This makes his mother's impending death even harder for him to take.
