One of the synthetic inhabitants of Coppelius Station in 2399, whose murder is used by Sutra to turn her fellow synths against organic life.
Saga is played by Nikita Ramsey in the two-part first-season finale of Star Trek: Picard, Et in Arcadia Ego. She is one of the androids built by Altan Soong and Bruce Maddox on the planet Coppelius, and she is among those who welcome Picard, Soji and the crew of La Sirena.
While the synths argue over the Admonition and the approaching Romulan fleet, Sutra decides that they must summon a higher synthetic power. To settle the matter she helps the captive Narek to escape and Saga is killed in the process, stabbed with her own brooch.
Her death persuades the community that organics will always kill them, and they begin to build the beacon. Soong later finds the proof of Sutra's part in the crime in Saga's own visual memories and shuts Sutra down.
