The Queen of The School, leader of the Pink Ladies. Young, strong, extremely beautiful in form, and mischievous. Sporting long blonde hair, a well-toned frame, wearing a reversible pink-to-black satin jacket, she was one of the most beautiful, most desired girls in the school. She yearned for a motorcycle-riding `bad boy', despite her growing disdain for what the smarmy T-Birds symbolized. In actuality, she was a gal looking for the machismo and danger that came with being seventeen and seemingly invincible, but also someone who would show her the respect and kindness she deserved. She would settle for nothing less.
She is the love interest of Michael Carrington, but she's interested in a cool rider. She falls for one (a disguised Michael) outside the bowling alley. When she's failing in English, she accepts Michael's help, returning his feelings in the process.
After being seen with him, Johnny, the leader of the T-Birds, gives her the option in turning down her leadership, in order to spare his image. She, however, refuses it. On the night of the talent show, a jealous Johnny & the T-Birds chase the Cool Rider with the Pink Ladies in pursuit. Assuming he's dead, Stephanie leaves, heartbroken. She & Johnny are crowned Hula Lula king & queen. When the Cycle Lords crashed the dance, the Cool Rider came in & saved the party. He unmasked himself as Michael, much to everyone's surprise. After Johnny, cooling down from his shock, accepts him as a T-Bird, Stephanie approves being with Michael. Stephanie is portrayed by Michelle Pfeiffer.
