- For the adoptive sister of Kara of Earth Thirty-Eight, see Alex Danvers.
An unnamed woman was the adoptive sister of Kara on Earth-X.
At one point, the woman tried to kill her adoptive sister Kara, but Kara eventually killed her instead.
When Kara saw Alex Danvers' love for the former's Earth One doppelgänger, she mocked Alex by mentioning her own adoptive sister, who didn't feel this way.
