- "Krypton's destruction sent a shock wave that knocked my pod off course and into the Phantom Zone. A region in space where time doesn't pass. I slept there for 24 years until somehow I got here."
- —Kara Zor-El[src]
The Phantom Zone is a region of space in which time stands still, and from which extremely little escapes.
Some while later, Kara Zor-El was sent to Earth. However, her ship veered off course and she was stuck in the Phantom Zone, only arriving on Earth decades later. As Kara left the Phantom Zone, she pulled Fort Rozz (prison) with her.
It was revealed by Indigo that Kara escaped the Phantom Zone when Indigo downloaded herself into Kara's pod and re- activated it, allowing it to leave the zone and resume its journey towards Earth.
