Grease

Cast:

• Danny Zuko: A smooth greaser from Chicago and successful womanizer, the de facto leader of the Burger Palace Boys has his life upended when he falls for a strait-laced square during his summer vacation leading into senior year.
   

• Sandra "Sandy" Dombrowski: An innocent ingenue when she moves into the neighborhood, she experiences severe culture shock as she learns her summer boyfriend's true nature but eventually transforms into Danny's fantasy dame after she is unable to resist her continued attraction to him.
   

• Betty Rizzo: A "tough little Italian", Rizzo is the cynical leader of the Pink Ladies and a strong alpha female who embraces the low culture and refuses to show her feelings. While she is condescending toward almost everyone, she and Danny have a particularly longstanding hostility toward each other, and she openly mocks Sandy in song.
   

• Kenickie: A hard-nosed tough guy, Kenickie has great pride in his investment, a used car he has named Greased Lightning. He has a tempestuous on-again, off-again relationship with Rizzo and is often at odds with Roger.
   

• Doody: A younger member of the Burger Palace Boys, Doody has some childlike mannerisms and is shown to have great difficulty when approaching his crush, Frenchy, or handling tense situations. He fantasizes about being a great rock-and-roll guitarist.
   

• Dominic "Sonny" LaTierri:  Sonny is a character who imagines himself a Casanova, but most high-school girls find him repulsive. He is also quite cowardly, wilting in the face of any criticism.
   

• Roger "Rump": A sardonic yet very self-confident Burger Palace Boy who is easily able to win over Jan and willing to go into a rumble with only a whip antenna as a weapon. He is frequently seen eating fast food and earned his nickname because he was a proficient mooner.
   

• Frenchy: A member of the Pink Ladies, Frenchy is the first person (other than Danny) to meet Sandy, and the two quickly become friends. She claims to have earned her nickname from being able to "French inhale" a cigarette. A very poor student with aspirations of becoming a beautician, but is equally inept when she drops out to attend beauty school.
   

• Marty: Marty is a seasoned member of the Pink Ladies, with much experience in wine, men, and cigarettes.
   

• Jan: A member of the Pink Ladies, Jan is a quirky Lutheran who has a voracious appetite and has moments of extreme bluntness. She and Roger develop a relationship over the course of the musical, but the two frequently bicker.
   

• Miss Lynch: A spinster English teacher and stereotypical disciplinarian. Her character role would be rewritten as Principal McGee for screen adaptions.
   

• Eugene Florczyk: The class valedictorian and an awkward nerd. He goes on to become a marketing executive after high school.
   

• Patricia "Patty" Simcox: A high-achieving cheerleader who befriends Sandy early in the play, Patty holds her own attractions to Danny and is especially drawn to him when he tries to change to please Sandy.
   

• Charlene "Cha-Cha" DiGregorio: A beastly girl who appears at the school dance as Kenickie's date, later ends up dancing with Danny, and is ultimately revealed as the girlfriend of a rival greaser gang member.
   

• Vince Fontaine: The smooth-talking 19-year-old disc jockey and Rydell High alumnus whose voice-overs serve as continuity for the musical. He appears on-stage during the school dance and serves as an on-air host at WAXX, the local top-40 radio station.
   

• Johnny Casino and the Gamblers: a low-rent rock and roll band that plays at the school dance.
