Earth-2
Alternate reality version
Earth-2 is a parallel Earth in DC Comics continuity, originally home to the Justice Society of America and Golden Age versions of superheroes.
The concept allows characters like Superman or Batman to exist in multiple versions simultaneously—one on Earth-1, another on Earth-2—with different histories and ages.
Earth-2 has been destroyed and rebooted multiple times across DC's various continuity resets.
The naming convention extends to other fictional multiverse settings: In that timeline, she's basically the Earth-2 version of herself.
