Maria and Juliet represent a slightly practical counterpart to both Tony's and Romeo's idealistic nature. Maria's brother Bernardo and Juliet's cousin Tybalt portray impulsively stubborn and violent characters who both die from wounds inflicted by the male lead. Lieutenant Schrank is similar to Prince Escalus, although Schrank is unfair in his treatment and attitude towards one gang- the Sharks. Anita and Nurse both take on the role as Juliet's confidant and trusted friend, often tampering with their roles as messengers. The mischievously tomboyish Anybodys, who desperately wants to be a Jet, would best fit into the role of Balthasar, since it was she who aided Tony in escaping after the rumble, as well as later informing the other Jets that Tony was being hunted. Finally, the character of Doc appears to fulfill the role of Friar Laurence because both possess somewhat of a peacekeeping nature. Doc attempts to get through to Tony by dramatically pleading, "Why do you live like there's a war on? Why do you kill?" (2.5). All of the characters are consistent to the heart and soul of the story as well as the slightly differing plots. .
West Side Story maintains Romeo and Juliet's intricate and exciting plot using appropriate adaptations to accommodate mid-twentieth-century pop culture. For instance, both artistic forms portray mutual disrespect between the parties. At the dawn of Romeo and Juliet, Capulet's cohorts harass Montague's. "I will bite my thumb at them; which is a disgrace to them, if they bear it," boasts Sampson (1.1.42-43). In the opening scene of West Side Story, several members of a Puerto Rican gang insult A-rab, a member of the opposing gang. It is here where Lieutenant Schrank becomes aware of the potential rumble. In Romeo and Juliet Escalus, Prince of Verona, threatens, "If ever you disturb our streets again, your lives shall pay the forfeit of the peace" (1.1.103-104). In West Side Story, Schrank mediates in his own way when he declares, "I got a hot surprise for you: you hoodlums don't own the streets"(1.
