Ophelia was the first ISO program discovered by Flynn and Clu. The pair showed Tron a recording of her rising from the Sea of Simulation. As one of the first ISOs a close releationship and mentorship with Flynn is formed. It is this closeness and first hand knowledge of Flynn's teachings, in addition to her own personality, that inadvertently results in other ISOs seeing her as a leader. As this embraces this role she is seen more in a white gown with an elaborate headdress and as her life and role in on the grid changes she eventually takes on a new name; Radia.
Giles served as her adviser and friend.
