Novels Jyn is introduced as a child in the prequel novel
Catalyst: A Rogue One Novel by
James Luceno, published in November 2016. In the novel, Republic Lieutenant Commander
Orson Krennic saves his old friend Galen Erso and his family from a coup, and enlists the scientist to develop energy technology using
kyber crystals that would ostensibly be applied to altruistic purposes. The research is actually necessary for the successful construction of
Emperor Palpatine's secret superweapon, the Death Star. Galen and his wife Lyra begin to suspect Krennic's ulterior motives, and plot to free themselves and their daughter Jyn from his grasp. Jyn appears as the main character in the novel
Rebel Rising by
Beth Revis. This novel takes place between the prologue and main narrative of
Rogue One. She also appears in the
novelization of Rogue One by Alexander Freed. Saw Gerrera appears with an eleven-year-old Jyn Erso in the novelization of the film
Solo: A Star Wars Story.
Film Rogue One Rogue One was released in December 2016, with Felicity Jones in the role of Jyn. In the film, scientist Galen Erso (
Mads Mikkelsen) is pressed into the service of the Empire against his will. When he is captured and his wife Lyra (
Valene Kane) is killed, their young daughter Jyn escapes and hides in the bunker. She is later rescued by a Rebel extremist named
Saw Gerrera (
Forest Whitaker) who cared for her after Galen's capture. Fifteen years later, Jyn is being held in Imperial custody on several criminal charges. The Rebel Alliance frees her upon intercepting a prisoner transport on the planet Wobani. They seek her help in contacting Saw Gerrera and persuading him to turn over information he has received about a powerful new weapon being developed by the Empire. Accompanied by Rebel intelligence operative
Cassian Andor (
Diego Luna) and the reprogrammed Imperial enforcer
droid K-2SO (
Alan Tudyk), Jyn travels to the desert moon
Jedha and reconnects with Saw, who shows her a holographic message that Galen recorded for her. Galen explains that he had secretly built into the Imperial superweapon, called the Death Star, a fatal flaw that can be exploited to destroy it. Jyn and her comrades, joined by the defecting Imperial pilot who brought the message,
Bodhi Rook (
Riz Ahmed), and a pair of local warriors, flee as the Empire's Death Star, an armored battle station the size of a small moon, destroys Jedha City. They track Galen to his research facility on
Eadu, where he and Jyn are briefly reunited just before he dies in a Rebel attack. Galvanized, Jyn proposes a mission to steal the schematics for the Death Star, stored on the planet
Scarif, but the council of Rebel leaders does not support it. Nevertheless, Jyn and a team of Rebel volunteers sneak away under the callsign "Rogue One" to infiltrate the Imperial facility on Scarif. She and Andor succeed in stealing and transmitting the plans, but the Death Star fires on the planet near the base. Jyn and Cassian embrace each other as they are engulfed by a fireball and killed. Chris Barsanti of
PopMatters noted that "Jyn's backstory also helps answer a question that's plagued fans ever since 1977: why did the Empire spend all that time and all those resources building a moon-sized space station only to leave one rather glaring and easily exploited vulnerability?" In the episode "The Stranger", Jyn witnesses a little girl's cat being confiscated by
stormtroopers. Jyn intervenes, snatching the pet and leading the pursuing stormtroopers to fall into a drain, and then returns the cat to the girl. Jyn reappears in the series in the episode, "Accidental Allies," where she encounters
Sabine Wren from
Star Wars Rebels. During the episode, Jyn picks up a holo-map stolen by Sabine that contains crucial intelligence, but is forced to flee when stormtroopers mistake Jyn as the actual thief. When Sabine realizes she has lost the map, she helps Jyn evade the stormtroopers and shares her own experience of working alone to persuade Jyn to give her the map. After some reflection, Jyn agrees and the women part ways. Jyn reappears once more in the episode "Jyn's Trade", where she helps a young thief learn a valuable life lesson. She was voiced by
Felicity Jones in the first season and Helen Sadler in the second season.
