Caroline O'Connor (died October 20, 2019) was a criminal based in National City. She was killed by Andrea Rojas before she could reveal who hired her.


Early life

Caroline O'Connor is a former special-ops command, she's highly rated in hand-to-hand combat, explosives, and she's a sniper. She went off the radar two years ago and somehow hooked up with the Aurafacian alien.[1]

Found by Supergirl and Guardian

Niles Jarrod goes to talk to her while at a night club. They find themselves making out in the bathroom, only for her tattoos to come alive, crawl inside his body and kill him.

Caroline finds Supergirl inside her apartment and shoots her with web-shooters against a wall. The Guardian breaks through her door and is able to fight her off before he is attacked with one of her tattoo spiders.

Supergirl and The Guardian find her next mark, Dr. Andrew Stern at the hospital, and though he is still attacked by the tattooed spiders, they are able to save him. Supergirl and Caroline have a physical hand-to-hand fight before Supergirl wins by knocking her off the overhang. Alex Danvers arrives and sucks up the Aurafacian with a device. Before they can question her, she is immediately killed by Andrea Rojas.[1]


Caroline was cruel and sadistic.
