Prior to the conflict between the Basics and ISOs, Quorra was Friends with Radia. She witnessed Clu's betrayal when he attempted to kill Tron and Flynn, and when Clu declared war, she - with the help of a prototype security program named System Monitor - attempted to warn Radia and the ISO's about him as well as combat the viral program Abraxas. After the purge, she attempted to kill Clu but was rescued Von System Monitor and they escaped using a Recognizer. However, the Recognizer crashed and only Quorra survived, leaving her stranded in the Outlands. With her energy depleted, she collapsed as her systems began shutting down, only to be saved Von Flynn at the last moment.
