Kallie Lintra, a female Resistance pilot, was the sibling of Tallissan Lintra. Her sister, Tallissan, came from the planet known as Pippip 3 and resided on a farm with their parents. Both Kallie and Tallissan were members of the Resistance, a paramilitary organization under the leadership of Leia Organa, a former senator from the New Republic.
In the year 35 ABY, Kallie Lintra took part in the battle fought on the planet Exegol, located in the Unknown Regions. The battle was against the Final Order, a fleet that the Sith Eternal cult had brought together. During this conflict, Lintra piloted an RZ-2 A-wing interceptor and was a part of the air strike team that had the responsibility of safeguarding the Resistance ground forces. Shortly before the Citizens' Fleet showed up, Lintra engaged eight TIE fighters that had surrounded her A-wing starfighter. She successfully destroyed three of these fighters before she was killed. General Poe Dameron, upon seeing Lintra's death, expressed his grief and remembered that they had lost both Kallie and her sister Tallie during the war against the First Order.
The 2020 junior novelization of the 2019 film Star Wars: Episode IX The Rise of Skywalker, authored by Michael Kogge, featured Kallie Lintra as a starfighter pilot.
