However, there have been times where she's used aliases:
* Linda Lee: In the earlier comics and the 1980s TV show, Kara used this name to blend in with humans while working as a reporter.
* Kara Danvers: In the current TV show, she uses this name (a slight variation on her real name) while working as a reporter and to hide her Kryptonian identity.
So, while she doesn't have a specific alias she consistently uses, she has adopted different identities to blend in and protect her secret.
