Princess Jasmine is the deuteragonist of Aladdin. She is longing to marry a man legitimately, despite her father's demands that she marry a prince. She rejects every prince in Arabia, until she meets Aladdin. When he goes into the palace posing as a prince, she falls in love with him as he takes her on a magic carpet ride. When Jafar learns Aladdin's secret, he takes control of Agrabah, becoming more and more powerful until Aladdin defeats him and proves his worth by setting Genie free, the Sultan allows Jasmine to marry the man she loves.
Though her role is similar to that of the film, there are a few significant differences to Jasmine's character. For instance, along with "A Whole New World", Jasmine performs several additional musical numbers, including "These Palace Walls", "A Million Miles Away" (another duet with Aladdin), and "Babkak, Omar, Aladdin, Kassim".
Additionally, during the climax, Jafar's first wish was notably different, and related to Jasmine. As opposed to wishing he was the ruler of Agrabah, Jafar's first wish was to make Jasmine his prisoner. However, in the movie, his final wish was initially to make Jasmine fall in love with him instead, using his newfound sorcery to transform Jasmine's blue bedlah outfit into a red slave-girl outfit first.
Aside from these factors, generally, Jasmine's role in the stage musical remains pretty much the same.
