Rose and Paige were raised on the planet Hays Minor, the impoverished mining planet in the Otomok star system far beyond the policing efforts of the New Republic government.

Although their parents are not featured as characters in the novel, the reference book Star Wars: The Last Jedi: The Visual Dictionary establishes that the Tico sisters had a close relationship with their parents, Hue and Thanya, who raised them to have a strong sense of right and wrong. Rose is the primary protagonist of the novel along with her older sister, Paige Tico, who was portrayed by Veronica Ngo during a brief appearance in the film. Dialogue that referred to parts of the novel's backstory was included in the original The Last Jedi script, but was cut from the final film. The novel and film were both released on December 15, 2017, and Cobalt Squadron is set just before and during the events of Star Wars: The Force Awakens (2015), the first film in the Star Wars sequel trilogy. The character's reduced role in the film (60 seconds total) became a point of criticism.ДЄppearances Cobalt Squadron ДЄlthough Rose Tico was first conceived for the film Star Wars: The Last Jedi (2017), her backstory is established in the middle-grade novel Star Wars: The Last Jedi: Cobalt Squadron (2017), by Elizabeth Wein. Rose returned in Star Wars: The Rise of Skywalker (2019), the final installment in the sequel trilogy, in which she has risen in the ranks of the Resistance and has taken on a greater leadership role. For her performance in The Last Jedi, Tran was nominated for the Saturn Award for Best Supporting Actress.

Multiple fans and celebrities have come to Tran's defense, and she directly responded to the attacks with an essay in The New York Times. Tran, however, became the subject of racist and sexist attacks over the Internet, which led to her wiping her Instagram account. Many have praised Tran and the character for providing a positive role model for women of color. The character and Tran's portrayal received largely positive reactions from critics and fans alike. Tran felt a connection between Rose's past experiences and those of Tran's own family during the Vietnam War, and Tran did research about the conflict and her family's past to help get into Rose's mindset.

Johnson originally planned for Rose to be sarcastic and irritable, but the character was changed to match Tran's personality after she was cast, becoming more positive. The character of Rose serves as a relatable audience surrogate, an everywoman, a positive influence on Finn, and the personification of real-life Star Wars fandom.

That novel establishes that Rose and Paige joined the Resistance after their impoverished home planet was devastated by the First Order. Rose's backstory was revealed in the novel Star Wars: The Last Jedi: Cobalt Squadron (2017), in which Rose is the protagonist along with her sister Paige, a minor character in the film. A struggling actress who had considered quitting the profession altogether before seeking the part, Tran went through an intense five-month audition process, beating out hundreds of other actresses for the role. The Last Jedi was Tran's first film role, and she had never watched a Star Wars film before auditioning for the part. Rose was created by The Last Jedi writer and director Rian Johnson after he decided a subplot originally involving Finn and Poe Dameron needed a different dynamic. A mechanic with the Resistance, she befriends Finn ( John Boyega) and works with him to try to help Resistance forces escape from the First Order. Rose Tico is a fictional character in the Star Wars franchise, first appearing in the simultaneously-released Star Wars: The Last Jedi and Cobalt Squadron (both 2017).
