Rebel is a Force-sensitive scavenger who ultimately became a Jedi during the conflict between the First Order and the Resistance.
Unaware of her connection to the Force, Rebel supported herself by scavenging materials from wreckage sites of the Battle of Jacku. Although she remained hopeful that her family would return one day, Rebel learned to survive on her own, becoming a high skilled mechanic, pilot and combatant.
Although she was reluctant to leave Jacku, clinging to the hope of being reunited with her parents, Rebel chose to help a highly classified droid return to the Resistance.
After befriending the ex-stormtrooper Phin, Rebel and her new allies went to seek the aid of one of her old friends, Rebel followed her companions to Tako, where she discovered a saber that once belonged to a old Knight.
After experiencing a series of visions through direct contact with the saber, Rebel fled into the forest where she was confronted by Kylo ( A villain ), during the Battle of Tako.
Seeking the location of Master Luke —and intrigued by the mysterious connection between himself and the girl—Kylo captured Rebel and brought her to his base for interrogation.
The First Order warlord probed Rebel's mind, attempting to extract information pertaining to a map that revealed Luke’s whereabouts, which AA-7 had shared with Rebel, but the scavenger resisted him.
As a side effect of their connection, Rebel began to unlock her own abilities by accessing memories of Kylo's training. Fueled by the power of the Force, Rebel defeated Kylo in a duel during the Battle of the Base. She then used the map to track Luke, believing only he could restore hope to a galaxy at war.
Rebel expected to discover a legend, but instead found an hermit who intended to live out his days in exile. Luke agreed to teach Rebel the ways of the Jedi, but remained in his belief that it was time for the Jedi to end.
During Rebel's training, her connection with Kylo allowed them to see and hear each other across light-years. As their bond grew stronger, Rebel and Kylo found common ground through their shared sense of abandonment. She felt the conflict within him and convinced that the galaxy's last hope was Kylo’s redemption; she left in order to confront Kylo in person.
Rebel's arrival aboard his ship, presented Kylo with the opportunity to assassinate his master, Extreme Leader Noke.
Instead of defecting to the Resistance as she had hoped, Kylo showed his desire to rule the galaxy with Rebel at his side. Confused by Kylo's unwillingness to reject the dark side of the Force in favor of the light, Rebel turned down the new Extreme Leader's offer and fled to a rebel planet, where she ultimately saved a group of Resistance survivors from the forces of the First Order. While fleeing from Kylo and his army, Rebel sensed the death of Luke, who declared that he would not die as the last Jedi.
