Jezzi, a female human, journeyed to the Andor household located on the planet Ferrix in 5 BBY along with Femmi, bringing supper and medicinal supplies for Maarva Carassi Andor, an elderly human, during one night. Jezzi later made a return trip to the residence. The subsequent day, Cassian Andor, Maarva's adopted son, who was absent during Jezzi's initial visit, inquired of the family droid, B2EMO, about the identities of those who had visited in his absence. B2EMO informed him of the visit by Jezzi and Femmi and started to detail the reason for Jezzi's return, but Cassian interrupted, specifically asking if anyone had been searching for him. Jezzi, together with Sammo, held the knowledge that Cassian's birthplace was actually Kenari, contrary to Maarva's assertion that he was born on Fest, a claim made to present them as family.
The television series Andor featured a mention of Jezzi in its first episode, broadcast on September 21, 2022. Her initial on-screen appearance was in "One Way Out," where she was played by Pamela Nomvete.
