Indigo is an android and a member of the Outsiders. Born in a distant future era, she comes to the 21st century badly damaged, and desperately looking for a cybernetic or mechanical organism capable of repairing her. In the process, she tries to install her self-repairing routines into the Metal Men, but they are incapable of assisting her in maintenance. Then she turns to Cyborg, but in the process, she damages him.
Attacked by the combined forces of Young Justice and the Titans she retreats, switching into an offensive mode.
Although the combined forces of the young superheroes best her, adding further damage, she is able to activate a dormant Superman Android before shutting down for repairs. Yet when the android comes after the young heroes (killing Lilith and Troia), Arsenal briefly reactivates the young female droid and sends her to stop the Superman Android before shutting down again.
When Arsenal reforms the Outsiders, he claims the female droid, now called Indigo, as a teammate.
Her memory was supposedly damaged in the aftermath of her dramatic appearance; any remainder was wiped out by S.T.A.R. Labs. Indigo displays a very naive personality, guilelessly taking pleasure in the simple things in life, like doing laundry for friends, bowling, and silent movies. She often struggles to learn how to behave in society, and takes her cues from those she lives with. As she grows more integrated in her quest to earn the acceptance and forgiveness of Nightwing and her teammates, she even manages to find love with Shift.
Indigo is actually Brainiac 8, and every bit the ruthless, inhuman villain that previous Brainiacs were (except for 5).[1] Indigo as the Outsiders knew her is essentially a subprogram, designed by 8's "grandfather" Brainiac 6 to endear her to the superhero community.
Death
Brainiac 8 had been sent back in time to kill Donna Troy, because a living Donna would negate Coluan domination over the "organics" after the Infinite Crisis. After a beating by the combined forces of Teen Titans and Outsiders the Indigo persona wrests control from Brainiac 8, and reveals herself to be a genuine personality.[2] Weeping, she begs Shift to kill her before the Brainac 8 persona could harm the people she loves. Shift, in tears, transforms her molecular structure into flesh, killing her in the process.
Rebirth
It seems that she was reformed and returned to her former Brainiac 8 glory as Superboy-Prime repairs her for his confrontation with the Teen Titans. Indigo is seen fighting Red Robin as well as the rest of the Titans.
Android Body: Indigo is an android from the future, as such her cybernetic programming vastly overpowers modern earth technology. The only beings on earth that can interface with it are Cyborg and the Metal Men. Her abilities seem to be even greater as Brainiac 8, as she revealed herself to be easily strong enough to defeat her powerful teammates such as Grace Choi, Thunder, and Starfire.
Energy Projection: She has used her powers to cancel out Jade's Green Energy constructs entirely.
